Fix Laptop DC Jack

It is possible to fix a laptop DC jack when it becomes defective. If you hired a professional to do it, the job may cost half the computer price.

Laptop computers receive power through the AC/DC adapter and the battery pack. The AC/DC cable occasionally can get damaged through regular wear and tear. It is important to repair the DC jack that the adapter plugs into as soon as possible, because most computers can only last on battery power for a few hours. It will take an hour or two to disassemble the computer and repair the power jack.
Taking Computer Apart

Position the computer so it is upside down on a flat surface. Take out all the screws from the bottom of the laptop with a screwdriver. Slide the cover off and store the screws in a drawer for safekeeping.

Take out any screws securing the hard drive housing with the appropriate type screwdriver. Once the housing is free, slide it away from the computer. Remove any screws holding the hard drive and pull it out.


Release the battery cover by pushing the lever to the side and pull out the battery.

Remove the screws in the hinges securing the LCD screen to the computer. Lift the screen away from the computer body, but do not disconnect any cables. Set down the screen near the computer.

Insert the blade of a flat head screwdriver into the groove on the right side of the laptop, above the top of the keyboard. Apply downward pressure to the handle to pry up the keyboard bezel. Pull off the bezel and set it aside.

Unscrew the screws holding the keyboard and remove it. Unplug the cable connecting the keyboard to the laptop.

Replacing Laptop DC Jack

Find the plastic piece on the motherboard that the DC jack fits into. Locate the jack if it dislodged and that is the reason for the power being cut off to the computer. Push the jack into the openings on the motherboard. Add a small quantity of glue on the base of the jack so it stays in place.

Replace the computer parts in the correct places. Test your computer to make sure the new jack works correctly. If the power still is not working, check the jacks contact points, as it may not be correctly connected. This should remedy the problem and power will be running to your computer through the AC adapter.
