Need to know, how to increase macbook pro battery life ??

Macbook Pro models may or may not get proper Apple’s 10-hour benchmark, but with the help of these tips & tricks you can improve the odds, you never know it maybe even do laptop repair in mumbai

Was very exited for buying an Macbook Pro as its features and battery life is vei beyond expectations. But After buying a 15-inch MacBook Pro with initially disappointing battery life it just didn’t match my expectation, So I became one of the skeptics. But as I like to search for the cause of the issue, I started running tests and I’ve extended my useful battery life dramatically. As i Process with the test, My one day’s test, mostly using a browser with a dim screen, I made it beyond 12 hours.

Unfortunately Apple’s 10-hour benchmarks for surfing the web over a wireless network connection and for watching iTunes video use relatively little power. The more you use your graphical part like Downloading High Images, playing games watching HD Video, apparently will low your 10 hour battery life.

Dim Screen

At the same time, Brighter the screen use high voltage and use extra battery life. Since 2016 Model Screen is better than 2015 Model. 2016 Macbook Pro screen used 30% Lesser battery than an 2105 Model. But tough if we can control the screen brightness at dim screen we get an good results. Atleast 20% hike in overall battery life

USB Devices

Anything which is been attached to the Macbook Pro it awakes the computer communication system. Plugging USB wake up the system and it consume the battery to run the USB drive if not attached that it can snooze in a low-power state. Even external drives with their own power supplies wake up the system.

Safari – Web Browser

Rivals are working to improve their efficiency, but Apple’s browser often does better on battery life. Part of the reason: It won’t let the MacBook Pro use its high-performance but power-hungry AMD graphics processor. The built-in Intel GPU isn’t as powerful, so sites like Google Maps may not be as smooth, but it uses a lot less energy.

Quit apps and close browser tabs if you’re not using them

Some of the apps & tabs get unknowingly running in background which consume power. It’s even more a problem if — like Adobe Acrobat, Lightroom and Photoshop, or like Google Maps in Chrome — they demand the Mac’s high-performance graphics chip. But if you force-close the background app which are not usefull with the task manager. Also, close the tabs which are running on chrome or any other browser.

Unplug dongles

The MacBook Pro’s new USB-C ports are great if you have the right cables and peripherals, but until then you might need dongles that need a chip to convert video data to HDMI or let you plug an older Thunderbolt 2 device into the Mac’s Thunderbolt 3 ports.

Watch video in full-screen mode and turn off closed captioning

That can extend your battery life by 45 to 60 minutes.

Laqptop Heating Issue

A hot computer is a bad computer. Excess heat can cause malfunctions and crashes, and permanently damage your hardware. And although laptops generally put out less heat than desktops (energy efficiency is a higher design priority), they have their own unique problems. They’re rarely as well ventilated as a desktop, and much more difficult to clean.Laqptop Heating Issue

 [Email your tech questions to [email protected] ]

Keeping a laptop cool is all about ventilation. If the hot air can’t escape, you’re going to have a problem.

Whenever your laptop is on, make sure that nothing blocks the vents (which are probably on the sides). Don’t put the PC on a pillow or a soft mattress, where it’s likely to sink in and get blocked.

And never, ever put your laptop in a bag unless it’s off, hybernated, or in sleep mode.

You’ll rarely find vents at the bottom of a laptop, yet heat tends to accumulate there. If the bottom is hot to the touch, consider buying a laptop cooler–a pad that goes under the laptop and whisks away the heat. Many of them have fans. Prices range from about 300 rs. to 700rs. I’m not going to recommend a particular model because I don’t use one. At least for my laptop, an empty but sturdy cardboard box is sufficient.

If you let dust accumulate in a PC, you’re bound to have problems. And you’ll have to fix those problems with a good cleaning.

Marco Chiappetta described the cleaning process in You’re a dirty, dirty, dusty PC. But he used a desktop, and desktop PCs are designed for easy user maintenance.

Laptops are trickier. You can try using a can of compressed air (I bought one recently for $4) to blow the dust away from the vents. But that’s a very limited solution. The dust may get away from the vent, but it’s still inside the PC.

Try this: Shut down the laptop and turn it over. Examine the bottom. You’ll likely find panels that can be removed with a small screwdriver. Open them up and see what you get access to. If you see dust, clean it away with compressed air.SPU Fan dust issue solve




Unfortunately, the real dust problem may be in places that require a more complicated dismantling. If you feel comfortable taking apart a laptop, go ahead. Otherwise, you may want to take it to a professional.

A soldering iron is composed of a heated metal tip and an insulated handle. Heating is often achieved electrically, by passing an electric current (supplied through an electrical cord or battery cables) through a resistive heating element. Portable irons can be heated by combustion of gas stored in a small tank, often using a catalytic heater rather than a flame. – See more at:

Data Recovery Software Works

Hard Disk Data Recovery

Data Recovery works almost 90% But some hard disk are the exceptional case, where hard disk is not readable or rewritable, Fortunately, the information that still remains on the storage can be recovered to a safe location. Recovery chances depend much on the data loss situation itself, but you should take into account that no information is recoverable after overwriting. For this reason you should never write anything to the storage until the last file is recovered.

Data recovery software serve to get data back after information loss with maximum possible result. Commonly, data recovery operation bases on storage scan to find specific information (deleted files, lost file systems) and assemble structures of a damaged file system.

Hard Disk Data recovery chances

Data recovery chances depend much on the actual cause of data loss and further user’s actions. To get maximum data recovery result it’s strongly recommended to stop any write access to the storage and run data recovery software immediately.

  • Data loss caused by file deletion
    Any deleted file remains on the storage until the storage space is re-used by other data. After file deletion OS may re-use disk space anytime to store a new file. Thus, even minor write to the storage may cause permanent data loss. Internet browser may result in overwriting of deleted files as well by saving cache or cookies to the storage. If you install the software to the same drive, your data are also under the risk of overwriting.Another factor that influences data recovery chances after file deletion is file deletion algorithm dependent on the file system. For Windows NTFS file system recovery chances are quite high, because if file descriptor remains on the disk, the software may easily take all required information about the file. Unlike NTFS, BSD UFS file system destroys information about file start, location and size permanently and together with high degree of file fragmentation typical of this file system leaves very slim chances for successful data recover.Other file systems (like FAT) feature average chances for data recovery. Here only part of information is destroyed (like information about file fragments), but information about file name, start and size still remains on disk. Heuristic algorithms still allow to ‘guess’ file fragments and recover good files. Please keep in mind, that due to lack of real information about allocation of file fragments any data recovery software may fail to detect real file position, especially if several fragmented files were deleted close to the same location on the storage.The scope of these factors make any file recovery software use a set of deterministicand heuristic algorithms to guess deleted file location. Please consider that these algorithms differ from vendor to vendor making recovery results differ as well.
  • Recovery after file system format
    After file system format a part of information on the storage is destroyed due to overwriting with new information of a new file system. Again, data recovery chances after format depend much on the original and new file systems.For instance, if a file system was formatted with FAT, it overwrite huge amount of storage space at disk start with zeros (empty block allocation tables) and therefore destroys any previous data. Even if previous file system was also FAT, the information about allocation of previous files will be lost completely. Other file systems usually allocate more or fewer structures to different storage locations.Recovery chances are much dependent on original and new file systems. Sometimes recovery chances are higher if the file system is formatted with the same file system type (e.g. NTFS), sometimes – not (e.g. FAT over FAT has worse recovery chances than XFS over FAT).Efficient data recovery software usually produce quite good recovery result after file system format. Most file systems (except those like FAT) may still keep file allocation information, directory records, file names etc. that allows to successfully reconstruct the file system. However, since new structures are written to the disk, some user information can be damaged and some files or folders can be lost.
  • Recovery after file system damage
    To this type of data loss data recovery software usually apply the same methods as for a formatted file system. Data recovery chances depend much on the actual file system damage that can be a damage of user files, file folders, file location, file name or all at once. Anyway, efficient data recovery software will help you achieve the highest possible data recovery results.
  • Loss of information about partition
    This type of data loss cause is probably the most unsubstantial. Working with this type of damage data recovery software identifies file system start by known file system structures scanning the storage. If the loss didn’t affect the file system itself, the data can be retrieved in its original form in the full scope.
  • Hardware failure

    Note: Never try to recover data from a failed or failing storage yourself. You may cause permanent data loss. The only exception is RAID systems where storage redundancy allows to recover good data without a failed unit.

    RAID failure may occur also effect file system. But if the file system remains intact, your RAID will have quite good data recovery chances ,the specifics article for more information about data recovery from RAID.

  • Recovery of wiped/overwritten data
    It is simply impossible. The myth about the possibility to recover lost files after overwriting is inherent from successful attempts to recover data from old diskettes and hard disks. These devices (with storage capacity from kilobytes to megabytes) used very wide magnetic trace and simple digital encoding to store the information. For this reason it was possible to read ‘traces of data’ after wiping or overwriting by calibrating read ‘head’ sensitivity and position.Modern systems use very thin tracks, high precision of head calibration and extremely high signal frequency near to the top of technology limit. Performance of modern chips only allows to pick good discrete signal from disk platter and never identifies any‘signal traces’. This scheme is impossible for any digital device (discrete signal frequency to handle such data lays much beyond the theoretical limit of electronic circuits).Please never trust those companies that claim to be able to recover data in this way.

Buying new laptop ? 8 Buying Guides keep in mind

Compact enough to carry with you, yet versatile enough to run demanding applications, a laptop is the best tool for doing serious work or play at home and on the road. While standalone tablets and smartphones are always popular, most people realize that everything from typing a research paper to crunching video to gaming works better on a laptop. So what type of laptop should you get?


There’s a wide variety of sizes, features and prices, which makes choosing the right laptop a challenge. That’s why you need to figure out what your needs are. To make the right call, just follow these steps.

1. Pick a Platform: Mac, Windows or Chrome OS?

This is not an easy question to answer, especially if you’re not familiar with both Macs and PCs. But this quick overview of each platform’s strengths and weaknesses should help.

Most laptops come with one of three operating systems: Windows, Chrome OS or Mac OS X (for MacBooks only). Choosing the right one is a personal preference, but here’s a quick summary of what each offers.

Windows 10

The most flexible operating system, Windows appears on many more makes and models than Chrome OS or Mac OS X. Windows notebooks range in price from under $200 to several thousand dollars and offer a wide array of features from touch screens to fingerprint readers to dual graphics chips. Windows 10, the latest version of Microsoft’s flagship operating system, provides a number of improvements over Windows 7 and 8, including the ability to switch between tablet and desktop modes, a revamped Start menu with live tiles and the Cortana voice assistant. While it still needs more touch-friendly apps for tablet users, Windows has millions of desktop programs available, including the full versions of the major productivity, graphics, video and development software


Apple OS X El Capitan


All MacBooks come with Apple’s own operating system, Mac OS X El Capitan. Overall, the operating system offers similar functionality to Windows 10, but with a different take on the interface that substitutes an apps dock at the bottom of the screen for Microsoft’s Start menu and taskbar. iPhone or iPad users will appreciate iOS-like features such as Launch Pad for your apps, superior multitouch gestures, and the ability to take calls and text from your iPhone. However, OS X isn’t made for touch, because no MacBook comes with a touch screen.


Chrome OS


Found on inexpensive “Chromebooks” such as the Lenovo 100S Chromebook, Google’s OS is simple and secure, but limited. The user interface looks a lot like Windows with an application menu, a desktop and the ability to drag windows around, but the main app you use is the Chrome browser. The downside is that there are few offline apps and those that exist don’t always work well. However, if you need a device to surf the Web and check email, navigate social networks and chat online, Chromebooks are inexpensive and highly portable, and they offer good battery life


2. Decide If You Want a 2-in-1

These days, many PC laptops fall into the category of “2-in-1s,” devices that can switch between traditional clamshell mode, tablet mode and other positions in between such as tent or stand modes. The 2-in-1s generally come in two different styles: detachables with screens that come off the keyboard entirely and flexible laptops with hinges that bend back 360 degrees to change modes. Most of these systems are much better at serving one purpose than the other, with bend-backs being laptops first and detachables offering a superior tablet experience. However, if you don’t see the need to use your notebook as a slate, you’ll usually get more performance for your money and a better productivity experience with a traditional clamshell laptop.

3. Choose the Right Size

Before you look at specs or pricing, you need to figure out just how portable you need your laptop to be. Laptops are usually categorized by their display sizes:
  • 11 to 12 inches: The thinnest and lightest systems around have 11- to 12-inch screens and typically weigh 2.5 to 3.5 pounds,
  • 13 to 14 inches: Provides the best balance of portability and usability, particularly if you get a laptop that weighs under 4 pounds.
  • 15 inches: The most popular size, 15-inch laptops usually weigh 4.5 to 6.5 pounds. Consider this size if you want a larger screen and you’re not planning to carry your notebook around often.
  • 17 to 18 inches: If your laptop stays on your desk all day every day, a 17- or 18-inch system could provide you with the kind of processing power you need to play high-end games or do workstation-level productivity.

4. Check That Keyboard and Touchpad

The most impressive specs in the world don’t mean diddly if the laptop you’re shopping for doesn’t have good ergonomics. If you plan to do a lot of work on your computer, make sure the keyboard offers solid tactile feedback, plenty of vertical travel (distance the key goes down when pressed, usually 1 to 2mm) and enough space between the keys.
Look for an accurate touchpad that doesn’t give you a jumpy cursor and responds consistently to multitouch gestures such as pinch-to-zoom. If you’re buying a business laptop, consider getting one with a pointing stick (aka nub) between the G and H keys so you can navigate around the desktop without lifting your fingers off the keyboard’s home row.

5. Pick Your Specs

Notebook components such as processor, hard drive, RAM and graphics chip can confuse even notebook aficionados, so don’t feel bad if spec sheets look like alphabet soup to you.
Here are the main components to keep an eye on.
  • CPU: The “brains” of your computer, the processor has a huge influence on performance, but depending on what you want to do, even the least-expensive model may be good enough. Here’s a rundown.
    • AMD A series or Intel Core i3 / i5: If you’re looking for a mainstream laptop with the best combination of price and performance, get a Core i5. Core i3 is a small step down. AMD A series CPUs are less common, but promise similar performance.
    • Intel Core i7: High-end performance for gaming rigs and workstations.
    • AMD E Series or Intel Pentium/Celeron: Found on low-cost laptops. It provides just enough performance to enable basic tasks such as video viewing, document editing and Web surfing.
    • Intel Atom: Also found on low-cost laptops and 2-in-1s. It offers basic performance but more battery life than Celeron/Pentium.
    • Intel Core m3 / m5 / m7: Low-power and low heat allow systems with these processors to go fanless. Performance is better than Celeron, but a notch below Core i3 / i5.
  • RAM: Some sub-$250 laptops come with only 2GB of RAM, but ideally you want at least 4GB on even a budget system and 8GB if you can spend just a little more.
  • Storage Drive (aka Hard Drive): Even more important than the speed of your CPU is the performance of your storage drive. If you can afford it and don’t need a ton of internal storage, get a laptop with a solid state drive (SSD) rather than a hard drive, because you’ll see at least three times the speed and a much faster laptop overall.
  • Display: The more pixels you have, the more content you can fit on-screen, and the sharper it will look. Most budget and mainstream laptops have 1366 x 768 displays, but if you can afford it, we recommend paying extra for a panel that runs at 1920 x 1080, also known as full HD or 1080p. (The difference is typically about $TK.) Some higher-end laptops have screens that are 2560 x 1600, 3200 x 1800 or even 3840 x 2160, which all look sharp but consume more power, lowering your battery life.
  • Touch Screen: If you’re buying a regular clamshell laptop, rather than a 2-in-1, you won’t get much benefit from a touch screen and you will get 1 to 3 hours less battery life. On 2-in-1s, touch screens come standard.
  • Graphics Chip: If you’re not playing PC games, creating 3D objects or doing high-res video editing, an integrated graphics chip (one that shares system memory) will be fine. If you have any of the above needs, though, a discrete graphics processor from AMD or Nvidia is essential. As with CPUs, there are both high- and low-end graphics chips. Nvidia maintains a list of its graphics chips from low to high end, as does AMD.
  • DVD/Blu-ray Drives. Few laptops come with optical drives, because all software and movies are downloadable. However, if you really need to read / write discs and your laptop of choice doesn’t come with a built-in DVD drive, you can always buy an external one that connects via USB for under $20.

6. Don’t Skimp on Battery Life

If you’re buying large, bulky notebook that you’ll use only on a desk near an outlet, you don’t have to worry about battery life. However, if you plan to use the laptop on your lap, even if it’s at home and or work, you’ll want at least 6 hours of endurance, with 8+ hours being ideal. To determine a notebook’s expected battery life, don’t take the manufacturer’s word for it. Instead, read third-party results from objective sources, such as our reviews.


7. Plan Based on Your Budget

These days, you can buy a usable laptop for under $200, but if you can budget more, you’ll get a system with better build quality, stronger performance and a better display. Here’s what you can get for each price range.
  • $150 to $250: The least-expensive noteboo
    ks are either Chromebooks, which run Google’s browser-centric OS, or low-end Windows systems with minimal storage and slower processors, such as the HP Stream 11 and the Lenovo Ideapad 100S. Use these as secondary computers only or give them to the kids.
  • $350 to $600: For well under $600, you can get a notebook with an Intel Core i5 or AMD A8 CPU, 4 to 8GB of RAM, and a 500GB hard drive, all respectable specs. However, at this price, most notebooks don’t have an SSD, a full-HD display or long battery life.
  • $600 to $900: As you get above $600, you’ll start to see more premium designs, such as metal finishes. Manufacturers also start to add in other features as you climb the price ladder, including higher-resolution displays and entry-level SSDs.
  • Above $900: At this price range, expect notebooks that are more portable, more powerful or both. Expect higher-resolution screens, faster processors and possibly discrete graphics. The lightest, longest-lasting ultraportables, like the MacBook Air 13-inch and the Dell XPS 13, tend to cost more than $1,000 (although you can get the Dell for less if you don’t opt for a touch screen). High-end gaming systems and mobile workstations usually cost upward of $1,500 or even as much as $2,500 or $3,000.

8.Mind the Brand

Your laptop is only as good as the company that stands behind it. Accurate and timely technical support is paramount, which is why Laptop Mag evaluates every major brand in our annual Tech Support Showdown. This past year Apple came in first place, followed by HP and Samsung.This past year Apple came in first place, followed by Microsoft and Samsung.
Support is only part of what makes a notebook brand worth your money. You also have to consider how the manufacturer stacks up to the competition in terms of design, value and selection, review performance and other criteria. In our 2015 Best and Worst Laptop Brands report, Apple placed first, followed by Dell and HP.

Laptop CPU Fan Not Working Properly | Laptop CPU Fan Making Noise | Laptop Cpu Fan Replacement | Laptop CPU Fan Diagnose

Laptop CPU Fan Not Working

If you have a working fan and it is properly connected with laptop motherboard and by bad luck it’s not spinning as usual.
First of all try to update laptop BIOS and if still nothing fixed then come down to CHIP LEVEL treatment of laptop. Now only two thing you can do to make laptop again working.

1. Check +voltage and senser track from fan connector, find out the CPU fan PWM controller circuit, cpu fan supply comes from output section of fan PWM circuit and this circuit not a smmiliar kind for all laptops and notebooks basically +5 voltage required on Vcc pin to spinning fan and to find out Vcc pin of CPU fan read my previous post no CPU COOLING FAN NOT WORKING
check cpu fan controller circuit and it’s all fusible resistor or small coil in circuit with a simple OME meter or continuity meter coil and fuse should be show zero continuity on there surface and if no continuity , found open component then you can bypass them using a unshielded Cooper wire.sure it will work again if other things are OK
and unfortunately no any coil and fuse you found on fan controller section then just resold this section using hot air-gun and check other components of fan PWM circuit if possible at your own way 🙂 you try all you best and still have same problem then now a good news for you because we can power up laptop notebook cpu fan Directly without using PWM controller circuit..
just found out the +5v track on motherboard nearby fan supply track ,connect the fan Vcc pin with +5v track using shielded thin wire jumper on motherboard and some time you can make your fan alive as just remove only the sence pin of fan from it’s connector if + five volt is already coming on the power pin of fan. your fan will start working but it will start spinning in a same speed non stop till the laptop is on. but doing this thing please confirm that which supply given to fan directly by jumper that will be generated after you turned on laptop.


How to Fix USB Port Setting After Trying all things in Windows/MAC

A common problem that arises for computer users is dealing with the USB Device not recognized error. This error is thrown after an USB device is connected to the computer but is not automatically detected.
When the error occurs, the Windows Device Manager may also list the component as an “unknown device” depending on the type of error.

Or the Laptop/Desktop completely unable to detected any electronics USB device no any error has shown on the display.
Some times computer only detect few hardware that don’t  draw power from the computer via the USB connection like printer and many other hardware that requires external power source to work.
Now let me divide this USB problem to parts to easy understand and diagnose the fault for both USB 2.0 and USB 3.0 :-

  1. Laptop not detecting any electronics device which draw power from USB port like pen-drive or any USB device (USB 2.0 & USB 3.0) detected.
  2.  Laptop detecting the hardware witch plugged in the USB 2.0 or USB 3.0 port but not recognizing the hardware device (error pop up shows  “USB not recognized”)

When you switch on the computer or connect any USB 2.0 or USB 3.0 devices, a BIOS message or Windows message may be displayed such as:

  • CMOS checksum error.
  • USB device overcurrent status detected.
  • Error 0701: USB Over Current On HC/Port – Bus:00H Dev :1DH Fun:01H / Port:00H
    Error 0701: USB Over Current On HC/Port – Bus:00H Dev :1DH Fun:02H / Port:00H
  • Error 0701: USB overcurrent error.
  • USB Device error.
  • Shutting down in 15 seconds
  1. Device recognized on normal 2.0 but not on 3.0.

Make sure before you read this solution, you made sure that everything is okay on the software side your device driver and OS settings like ”USB 2.0 or USB 3.0 Hub Power Management should be disable or have configure correctly and also BIOS settings are configured correctly and up to date. Make sure that USB is enabled from bios settings.

Before I stat the solution of this problem let me introduce some basic thing about the electronics behind the USB.

We have two type of USB.

Both power up the device from +5v  Vbus pin to power up the small USB devices like pendrived and mouse  the difference is USB 3.0 has double data lines for Superspeed high speed interface.

Both port detect any device by their data lines.


How to Fix Usb port

  1. Laptop detecting the hardware plugged in the USB port but not recognizing the hardware device (error pop up shows  “USB not recognized”)

If the +5v is okay on the port and the system only detect  the hardware not able to recognize the hardware that means something is malfunction in the date lines tracks form USB port to south bridge. Check the coils and fuse able SMD resistor for open which are connected in series of data liens with the malfunctioning port. If coils not found open then heat up the complete motherboard using the hot air gun.

Make south bridge and the nearly components of USB port  you main focus when to heating up the main board. After did all thing if you sill have problem then it means south bridge is dry-sold or the some track is broken on main board.

now only two things can be done to resolve this problem..reflow or reball the south bridge.

if this ‘not recognizing’ problem comes with the all ports of laptop or desktop board then the problem happens due to BGA south bridge if you already tried bios reflashing.

But don’t worry i m not gonna tell that the time is to change the south bridge. Because it’s pretty risky work to replace a big BGA chips on a laptop motherboard.

Just you need to re flow the south bridge using a simple hot air gun or a IR BGA rework station.

You can see my older post if you gonna use the simple hot airgun to reflow you south bridge.

Be carefully because if you not ever had any BGA re flow. a mistake can be damage your main board or the chip.

  1. Laptop not detecting any electronics device which draw power from USB port like pen-drive or any USB device detected.

This problem is related with main board of desktop laptop computer. If you facing this kind of problem then first thing that I would like to let you know that is this problem happens due to the missing +5v on the port. because if laptop not able to detect device that draw the power from the USB port to working like pen drive mouse keypad. If USB device didn’t get the power how they will work?

In every laptop and in some desktop mother board manufactures use a switch circuit for power management and protect the motherboard from shorted USB device and to protect form overload. Mostly you will found the VBus pin fuse open or the switch IC faulty.

This switch is normally is a SMD chip that provide the power. Each and every USB port can be have a single chip as there power management switch and also a chip can manage two or more port depends on the manufacture.

So simply take out the motherboard of laptop on your working desk and trace out the track of VBus of the port that malfunctioning and check the fuse or coli for open if this used in series of . pin to USB power manger chip. if it’s okay then now check the input voltage of chip if available  first of all resold the chip and then make sure chip gets the enable signal is available on the chip. you can download the chip data sheet to know the pin details of chip. But as per my experience you don’t have to download the chip data sheet because mostly laptop have same chip for every port so it’s easy to diagnose that chip has problem or not. Simply check the same voltage on the so this fault happens some of reasons if you ever plugged in any sorted USB device in USB port or due to port broken and also can be happens.

  1. When you switch on the computer or connect a USB device, a BIOS message or Windows message may be displayed such as:
    • CMOS checksum error.
    • USB device overcurrent status detected.
    • Error 0701: USB Over Current On HC/Port – Bus:00H Dev :1DH Fun:01H / Port:00H
      Error 0701: USB Over Current On HC/Port – Bus:00H Dev :1DH Fun:02H / Port:00H
    • Error 0701: USB overcurrent error.
    • USB Device error.
    • Shutting down in 15 seconds

If you get the this kind of error message on starter (POST) screen wham you turn on the laptop or desktop computer than that meas any short circuit in the USB port.

So simply check the port for physically broken normally the broken USB socket is the most reason of shorting in USB power supply line.

if no any port the seems like broken or short the problem will can be in USB power manager chip simple check the USB  VBus  shorting with ground.

usb power now working

And the good news if you have problem with USB power chip and it’s availability is out of reach from you then u can easily bypass the USB port supply… remove the USB power chip and just short the input and output track of chip using a wire.

If USB 3.0 device not recognized by the usb 3.0 port and your hardware device and the settings of USB is seems okay then check the StdA_SSTX, StdA_SSRX pins or and coil for open and dry.

Repairing a Laptop is more trickier than repairing a desktop computer. how much does laptop repair cost ?

Frankly Speaking, Service from small business run by people is better than looking for Authorize Service Center, as it will charge unnecessary things and it consume a lot of time. Ask friends, relative, Search on internet for Laptop Body Fabrication and the name of your town.

That small business will mostly buy the replacement body from online retailer Shantilaptop. You can contact on 8879192872 for the available models of the laptop as well as the service which they provide and at what price (Usually about 1500rs.), Its a good idea to have the information on your call, so that its save your time to visit the store.

You’ll really need Shantilaptop, if you decide to do repair yourself. (Don’t try if possible)

Search on google for best laptop body fabrication, and you will get the best laptop repair cost of that on call.

If you can’t fix it go for second hand laptop, if you can’t afford second hand laptop.
