Troubleshoot as needed

If you can’t remove the DC jack it may not be a plug in type some must be de-soldered. Before beginning the repair search the type of DC jack within your specific laptop.

If some screws don’t go back in, you may have gotten confused with the screws. Different parts of the laptop carry different sized screws.

Most times the laptop doesn’t need half the screws in it, the screws make it stronger against drops. You can purchase the screws in most electronic and/or computer repair stores.

If after the repair is complete and the laptop still does not charge or turn on, you may have had another problem. Take a look at the Related Article about diagnosing this problem. The problem could have a simple fix.

If the keyboard is not working, you will have to remove the keyboard and make sure that the strip connector is locked in.

If the DVD drive doesn’t slide into its slot smoothly, don’t try to jam it in that could damage a cord. Use the computer chip lifter to move the cords out of the way of the DVD drive.

When pulling the face plate up be sure to go from corner to corner slowly. Going too fast could snap the joints.

Take pictures as often as possible during the dis-assembly period to aid your memory in the re-assembly period.

A lot of times there are various different screw sizes for different parts of the laptop. An egg container and some labels can help you sort them out so that you don,t get confused or lose any screws.

Work on a soft cloth so that the laptop doesn’t scratch

If your tough pad is not operating you may not have connected the touch pad strip connector

If your keyboard is not operating you may not have connected the keyboard strip connector.

Be sure to connect all peripherals or else they will not work and you will have to dis-assemble to entire laptop again.

If laptop doesn’t turn on you may need to go back and connect the strip connector that is connected to the power button.
