How to Repair Laptops

Although any number of errors can occur that can impede normal operation of your computer, repairing your laptop may not be quite as difficult as you may think. There are a handful of more common problems that should always be troubleshooted first for a laptop and likely will lead to the normal operation of a laptop once these issues are repaired--whether it is a battery problem or display malfunction. Typically repair of any one part requires only a few steps.



Things You'll Need:

* Replacement battery External monitor Phillips screwdriver Replacement LCD display

#

Examine the laptop carefully and check for the obvious. Check the AC power adapter and make sure it is plugged into the wall and providing power to the laptop. Try switching power outlets. The problem may not be a lack of battery power or the AC power adapter connection but rather the power outlet itself.
#
Step 2

Check the laptop battery. How old is the battery? After a number of full charges--usually 1,000 for modern batteries--the battery will start to significantly lose charge and may need to be replaced. Shut off the laptop, flip it over and find the outline on the bottom, at the bottom back edge of the computer. Although laptops differ, there should be a sliding mechanism to the left or right of the battery outline that, when activated, allows the user to pop out the old battery. Slide a new battery in until it clicks snugly into place.

Step 3

Plug in your laptop into an external monitor to see if your current laptop LCD display is functioning properly. Use a VGA cable. Turn on the external monitor and see if it displays the contents of your laptop's desktop. If it does, the problem lies with your laptop LCD display.

Step 4

Replace the LCD display of your laptop. Before doing so, shut the computer down, remove the AC adapter and remove the battery once more. Use a Phillips screwdriver and remove the screws surrounding the perimeter of the bezel that encloses the LCD display. Pop these screws out and then carefully peel off the bezel, starting at one corner and working slowly.
#
Step 5

Unscrew the screws located on the metal brackets. There are two metal brackets, one on each side of the monitor display. These brackets can be seen only after the bezel is removed.
#
Step 6

Unplug the inverter cable. This cable leads directly into the inverter beside it. The inverter cable can be found just below the display, at the bottom center of the computer. It can be seen only after the bezel is removed.
#
Step 7

Slide out the old display carefully after the cable is disconnected. Then, slide the new display in. Reattach the inverter cable. Replace the screws back into the metal brackets on the side of the display enclosure, and then fix the bezel back over the display. Replace the bezel screws, and then turn on your computer to use your new LCD display.
