DC Jack Repair on Gateway MA7 Laptop

admin — Mon, 06 Jul 2009 10:53:48 +0000

Here I have a DC Jack to replace on a Gateway MA7 Laptop, there was no power to the laptop and the battery would not charge. These symptoms can also indicate a faulty AC Adapter so this was tested before any work was carried out on the laptop.

To replace the DC Jack you need to remove the motherboard from the laptop completely, this is a long and complicated process and alot of screws to account for. It takes me 2 hours to complete the DC Jack repair on a laptop so allow yourself more time if this is your first attemp.

If you do not not have a desoldering iron station I do not recommend you attemp a DIY repair.
