How to upgrade RAM in Toshiba Satellite A45

posted in: 8. Toshiba | 33

In this guide I explain how to upgrade RAM (memory) in a Toshiba Satellite A45 laptop.

If you search for memory slots on the bottom of the laptop, you will not find any because both slots are hidden under the keyboard.

In order to access both RAM slots you’ll have to remove the keyboard. Don’t worry, it will take about 5 minutes even for inexperienced users.

Before you start,  turn off the computer, unplug the power adapter and remove the battery and of course, proceed at your own risk. 🙂


Insert a small flat head screwdriver under the keyboard bezel and lift it up.

Gateway NX570X laptop

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.
