A broken power jack can render your Acer laptop nothing more than an expensive paperweight. Without a working power jack, the rechargeable battery in your laptop can't get power and your laptop won't turn on. Replacing the power jack can be expensive if you send it to a repair service, and you'll be without your computer for a while. You can save yourself the time and expense by learning how to do it yourself. Keep in mind that attempting to replace the power jack on your Acer will void your warranty, so do not attempt this if your laptop is still under one. Contact Acer for an authorised service centre.

Remove the memory modules. Spread the latches on both sides of the memory to cause the memory sticks to pop up. Slide the sticks out of the laptop base. On most Acer models you can also remove the wireless card at this point, as it is typically located right next to the memory modules. Disconnect the two antenna cables connecting the card to the motherboard. Spread the latches just like you did with the memory and remove the card.

Locate the power jack, typically found in the back left corner of an Acer laptop. Turn the motherboard over and locate the solder holding the power jack in place.

Once the solder has been loosened or removed, remove the old jack from the motherboard.
Insert the new jack into the motherboard and solder it in place.
