In this guide I explain how to remove and upgrade memory in a Toshiba Satellite M100 or Satellite M105 laptop. I will upgrade it from 512MB (default size) to 2GB. This model has two RAM slots. One of the RAM slots can be easily accessed from the bottom but another one is hidden under the keyboard.
Let’s start with the hidden internal RAM slot. In order to access this slot we’ll have to remove the keyboard.
Make sure the computer is turned off and the battery is removed.
Insert a small flat head screwdriver between the speaker cover and laptop base.
Lift up and remove the speaker cover.
