In the following guide I take apart a Gateway NX570X laptop.

I think my disassembly instructions will work for other Gateway NX570 models too.

In my case the battery started charging intermittently with the AC adapter connected.

In order to charge it 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 (DC jack) and it has to be replaced or resoldered.

I’ll be removing the system board so I can access and repair the jack.

Here’s how you can replace or upgrade memory (RAM) in a Toshiba Portege M400 Tablet PC.

As you see on the picture below, there is no access to the RAM slots on the bottom.

Why? Because both RAM slots are hidden under the keyboard.
