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.
Remove two screws securing the keyboard. Release the latch located above the key F8 and lift up the keyboard.
It is not necessary to disconnect the keyboard while accessing the internal RAM slot. Simply turn the keyboard upside down and place it on the palm rest.
The internal slot is hidden under a metal cover. Remove two screws and remove the cover.
Remove the original memory module installed into the internal slot. In my case I had a 512MB module installed.
Install a new 1GB module into the internal slot.
Install the metal cover, keyboard and speaker cover.
Now we’ll move to the second slot located on the bottom.
Remove one screw securing the cover. Remove the cover.
In my laptop this memory slot was not occupied.
Install another 1GB module into the bottom slot.
Both RAM modules should be detected and configured automatically as soon as you turn on the laptop.
You can check memory size in the BIOS setup menu or System Properties.
Toshiba Satellite M100/M105 will take up to 2GB RAM total. You can install up to 1GB RAM module into each slot.
Use DDR2 PC-5300 SODIMM. You can install faster memory, for example DDR2 PC-6400 but it will slow down and run at PC-5300 speed.
UPDATE: I checked some RAM sellers recently and they say that Satellite M100/M105 can handle up to 4GB.
Have you been able to install 4GB into your Satellite M100/M105?
