Upgrading memory in the Toshiba M400 Tablet PC

My new laptop is a Toshiba M400 Tablet PC – it only came with 1GB RAM which I planned to upgrade. I ordered two 1GB sticks of M400–compatible RAM from EZ-Computer (EDGE MEMORY – PERIPHERAL KTT667D2/1G-PE 1GB PC25300 NONECC UNBUFF 200PIN DDR2 SODIMM). When the sticks arrived, I started poking around the back of the tablet only to discover that there was no memory compartment!? After searching around the net, I came across this awesome detailed explanation of the procedure from Toshiba – it was a little more than I bargained for but only took about 10 minutes once I got started. You basically have to remove the keyboard to get access to the memory compartment. I had to do a similar thing a few years back to get access to the hard drive in a VPR Matrix laptop that Best Buy used to sell.

I took a few pictures to help out anyone else going through the same process …


I started by unclipping the keyboard holder from one side and remove it to get access to the screws for the keyboard.


Removed the screws then folded the keyboard over.


Now we can see the memory compartment, remove the screws on the left of it.


Now simply replace the memory sticks.

Anyone want to buy two 512MB sticks?

Look out for a post soon about my experiences using the tablet for managing and building software.

    Hey, thanks for putting this page out there! Saved me a ton of time taking the laptop apart to upgrade the RAM!
