Computer Laptop Repair

This page is all about basic Laptop computer repair tips. You will learn how to troubleshoot and fix minor laptop problems. If you are looking for an advance step-by-step Laptop repair and maintenance guide then I highly recommend Laptop Repair Online Video Course.

In Laptop computer repair one should pinpoint the accurate problem before taking any action. For example, when a laptop does not function you may rush to change its battery, but the problem may be a bad connection with the power cord. In the same manner a “dead” LCD screen may be a video adapter failure, a main board, burnt out backlight or a bad inverter.

Laptops parts are sensitive and expensive. Trial and error is not a very good solution with all laptop problems.

Some Laptop problems cannot be repaired or not worth repairing. If you can see blocks of dead pixels or a physical crack in the screen then you need to replace the laptop screen. Fixing these type of problems may be difficult or very costly.

Laptop user with a little bit of knowledge can fix common laptop computer problems, usually occurred due to regular usage. However, identifying the problem is crucial before repairing the laptop.

Repair laptop display problems

If there is complete display failure, first of all check the status of the power. If you were able to hear the fan of your laptop and now it isn’t, that means it’s a main board or power failure, not a video failure.

Another common practice in laptop computer repair is to connect a normal computer monitor with a standard VGA connector, if your laptop does not light up the external monitor means either the internal video adapter or the motherboard has failed. In case the external monitor is working then your laptop video subsystem has a problem and need to investigate further.

If there is a display problem in your laptop computer and the number of dead spots or columns or whole row increases slowly on the screen, it indicates that the assembly of actual LCD is bad. In the same way, if the screen flickers it is probably the failure of backlight or inverter.

Other common Laptop problems

Laptop computer problems can cause by internal disorders of the physical connectors. The common victims are network or modem ports, which may be detached within the case or the breaking of the power connector solder joint of the board. Such problems are very dangerous because here you need to open up the body of the notebook for soldering. Be careful to use a decent solder sucker for quick clean up.

Laptop problems are often caused by virus attacks. In this case they behave very strangely. One common symptom is the screen display goes off though the laptop is running. This can be due to graphic display driver files affected by virus or sometimes deleted by anti virus considering it to be a strange file. Re-starting the laptop in Safe Mode and re-installing the display drivers will repair this problem.

If you are not tech savvy, my personal advice is to hire a professional technician for Laptop computer repair unless it is software related problem. It is always better if you can contact s Laptop Repair Company authorized by the Laptop manufacturer.

How To Troubleshoot a Computer That Won't Turn On

It's a dreadful way to start a day - you press the power button on your computer and nothing happens. Few computer problems are more frustrating than when your computer won't boot.

There are many reasons why a computer won't turn on and often very few clues about what might be the problem. The only symptom is usually the simple fact that "nothing works" which isn't much to go on.
Add to this the fact that whatever is wrong could be an expensive part of your PC to replace - like the motherboard or CPU.
Do not fear because all may not be lost! Here's what you need to do:
  1. Read #1 below (it'll make you feel better).
  2. Pick the best troubleshooting guide (#2 - #9) based on how your computer is acting or #10 if your PC stops at any point because of an error message.
Note: All of these "computer won't start" troubleshooting guides apply no matter what Windows operating system you have installed on your hard drive, including Windows 7, Windows Vista, and Windows XP. Steps 1 through 5 even apply to other PC operating systems like Linux.

1. Don't Panic! Your Files are Probably OK

Files and Folders - Your Files are Probably OKWhen faced with a computer that won't start most people tend to panic, worried that all the data on their PC is gone forever.
It's true that the most common reason a computer won't start is because a piece of hardware has failed or is causing a problem but that hardware isn't usually a hard drive, the part of your computer that stores all of your files.
In other words, your music, documents, emails, and videos are probably safe - just not accessible at the moment.
So take a deep breath and try to relax. There's a good chance you can figure out exactly why your computer won't start and then get it back up and running.

2. Computer Shows No Sign of Power

Computer Shows No Sign of PowerTry these steps if your computer will not turn on and is showing no sign at all of receiving power - no fans running and no lights on the computer case.
Important: You may or may not see a light on the back of your PC depending on the kind of power supply you have and the exact cause of the problem.
Note: Don't worry about the monitor yet. If the computer is not turning on because of a power issue then the monitor certainly can't display anything from the computer. Your monitor light will likely be amber/yellow if your computer has stopped sending information to it.

3. Computer Powers On... and Then Off

Computer Powers On and Then OffFollow these steps if, when you turn your computer on, it promptly powers back off.
You'll probably hear the fans inside your computer turn on, see the lights on the front of your computer turn on or flash, and then it will all stop. You won't see anything on the monitor and you may or may not hear beeps coming from the computer before it shuts off by itself.
Note: As in the previous scenario, don't worry about the state your monitor is in. You may have a monitor issue as well but it's not possible to troubleshoot it quite yet.

4. Computer Powers On But Nothing Happens

Computer Powers On But Nothing HappensIf your computer seems to be receiving power after turning it on but you don't see anything on your monitor, try these troubleshooting steps.
In these situations, the power lights will stay on, you'll likely hear the fans inside your PC running, and you may or may not hear one or more beeps coming from the computer.
This situation is probably the most common in my experience working with computers that won't start. Unfortunately it's also one of the most difficult to troubleshoot.

5. Computer Stops or Continuously Reboots During the POST

Computer Stops or Continuously Reboots During the POSTUse this guide when your computer powers on, shows at least something on the monitor, but then stops, freezes, or reboots over and over again during the Power On Self Test (POST).
The POST on your computer may look like the screenshot to your left or may instead simply show your computer maker's logo.
Important: Don't use this troubleshooting guide if you encounter an issue during the loading of the operating system, which occurs after the Power On Self Test is complete. Troubleshooting Windows related reasons why your computer won't turn on begin with #6 below.

6. Windows Begins to Load But Stops or Reboots on a BSOD

BSOD - Computer Turns On But an Error Prevents Windows From LoadingIf your computer begins to load Windows but then stops and displays a blue screen with information on it then try these steps. You may or may not see the Windows splash screen before the blue screen appears.
This kind of error is called a STOP error but is more commonly referred to as a Blue Screen of Death or a BSOD. Receiving a BSOD error is a common reason why a computer won't turn on.
Important: Choose this troubleshooting guide even if the BSOD flashes on screen and your PC restarts automatically without giving you time to read what it says.

7. Windows Begins to Load But Stops or Reboots Without an Error

Try these steps when your computer powers on, starts to load Windows, but then freezes, stops, or reboots over and over again without generating any kind of error message.
Windows Begins to Load But Stops or Reboots Without an ErrorThe stopping, freezing, or reboot loop may happen on the Windows splash screen as shown to the left or even on a black screen, with or without a flashing cursor.
Note: If your computer won't start and you see a blue screen flash or remain on the screen, you're experiencing a Blue Screen of Death and should use troubleshooting guide #6 above.
Important: If you suspect that the Power On Self Test is still going on and that Windows has not yet started to boot, a better troubleshooting guide for why your computer won't turn on might be #5 above. It's a fine line and sometimes hard to tell.

8. Windows Repeatedly Returns to the Advanced Boot Options Screen

Windows Repeatedly Returns to the Advanced Boot Options ScreenUse this guide when nothing but the Advanced Boot Options screen appears every time your restart your computer and none of the Windows startup options work.
In this situation, no matter which Safe Mode option you choose, your computer eventually stops, freezes, or restarts on its own, after which you find yourself right back at the Advanced Boot Options menu.
This is a particularly annoying way in which your computer won't turn on because you're trying to use Window's built-in ways to solve your problem but you're getting nowhere with them.

How to install Windows 7 using bootable USB drive

We have been using CDs and DVDs to install operating systems on our computers for quite some time now. With the ever increasing popularity of netbooks, things are about to change. In such cases, an external optical drive or a USB drive is required.
There are a few situations where the use of USB drive brings a certain benefit:
(1)When you want to create a live USB from an ISO image
(2)You can protect your original install media from wear and tear.
(3)When you are trying to install Windows on a netbook or your optical drive is broken.
For starters, not every PC is capable of booting from a USB flash drive. For the most part, computers manufactured within the last two years are generally able to boot from a flash drive.The pen drive capacity must be a minimum of 4 gb.
Now the following are the steps required to install windows using a bootable USB:
(1)First install the boot files onto it by following either of these methods.
  • Using Windows 7 USB creator tool :How to create bootable USB Windows 7
  • Manually : How to create bootable Windows 7 USB manually
(2)The next thing that you must do is to configure your PC to allow you to boot from the flash drive. This is all done through the computer’s BIOS Setup.
(3)You can access your computer’s BIOS by pressing a specific key immediately after you turn the PC on. The key varies, but it is usually either [F1], [F2], [Delete].
(4)Once you are in the BIOS Setup, you should verify that all of your computer’s USB options are enabled. This might include things like support for legacy USB devices or support for USB 2.0.
(5)If there is a time out setting for USB devices, you should set it to the max to insure that the system doesn’t time out while waiting on the USB device to boot.
(6)Next, find the section on boot device priority. Normally, a USB flash drive (which is usually listed as USB-HDD, but may be listed as a removable device) will have a very low boot priority.
(7)If the USB flash drive’s boot priority is lower than the hard disk (listed as HDD) then the only time the computer would ever boot off of the USB flash drive is if the system were to fail to boot from the hard disk. You must therefore rearrange the boot device priority so that the flash drive has a higher priority than the hard drive.
(8)After configuring the PC reboot the system and insert the USB pendrive onto which the boot files are created and install the new WINDOWS 7.

Microsoft: Fix It For Me Now!

It does not matter how something on a person's computer broke. It could be the result of a malware infection, a conflict with a third-party application, or self-help that backfired. Regardless of the source of the problem, we all want Microsoft to Fix it and to Fix it Now.

Although Microsoft has long provided Knowledge Base articles with detailed instructions for repairing problems such as those mentioned above, the instructions generally involve registry edits -- which is understandably something the average home user generally will shy away from doing.
Along comes Microsoft Fix it, a tool to automate those fixes that you want now, relieving you from worrying about messing up a registry edit that could result in your computer in worse condition than before you attempted the fix.

The Fix it Team has created a wide range of fixes covering problems in Windows, Internet Explorer, Microsoft Office programs such as Excel and Word, Outlook, Windows Media Player, Zune and a whole lot more. Many of those fixes are a result of Windows Error Reporting (WER) where people like you and I allow the submission of crash reports to Microsoft. By submitting those reports, Microsoft Product Support Reports (MPSReports) is able to analyze the results and fixes for repeated problems are added.

To check that Windows Error Reporting (WER) is enabled, do the following:

Windows Vista

    Click Control Panel > System and Maintenance > Problem Reports and Solutions > Change settings > Advanced settings > Select "Automatically check for solutions".

Windows XP:

    Click Start > Right-click My Computer > Properties > Advanced Tab > Error Reporting.

If you are not sure where to start, you can try Microsoft Automated Troubleshooting Services (Microsoft ATS) to detect problems on your machine and automatically fix any common problems.

The Fix it Team has provided multiple resources to assist you in locating a Fix it solution:

   1. Fix it for me blog
   2. Fix it Gadget (Download link)
   3. Fix it Solutions Page
   4. Microsoft Fix it Solutions Center

The next time you need a solution for a problem, let Microsoft Fix it for you.
