Lately I’ve been seeing exactly the same problem with the power socket in some newer Toshiba Satellite L305/L305D and Satellite L355/L355D laptops. I don’t know if it’s a poor design or people just not careful enough with their laptops, but the power socket in these models breaks very often.

On the picture below you can see a good working power socket. The power jack is seated correctly. It’s tight and will not move when you plug in the adapter.

On the next picture you see a broken socket. There is a gap between the power jack and laptop base and when you plug the AC adapter inside the jack it feels very loose. In some cases, the power jack disconnects from the laptop base and you cannot plug in the power adapter at all.

In the following guide I’ll be taking apart a Gateway NX570X laptop. I think my disassembly instructions will work for other Gateway laptops in the NX570 line too. Please let me know if you have a different Gateway laptop and this guide works for you, you can mention your model in the comments below.

The laptop I’m fixing stopped charging the battery even though the AC adapter works properly and outputs correct voltage. I tested the adapter with a voltmeter. Actually, it’s charging the battery but only intermittently, when the AC adapter pushed in firmly. In order to charge the battery I have to adjust the AC adapter plug inside the power socket on the back of the laptop. Apparently, there is a problem with the power socket (aka power jack) and it has to be replaced or resoldered. OK, let’s take this lappy apart. I’ll be removing the system board so I can access and repair the power jack.
