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.
According to manufacturer specifications a Toshiba Portege M400 Tablet PC can handle up to 4GB memory total.
That means you can install up to 2GB module into each slot.
Toshiba Portege M400 laptop configured with PC2-5300 DDR2 667MHz RAM.
You can easily upgrade RAM to 4GB yourself; all you need is a couple of screwdrivers, two 2GB modules and 15 minutes of your time.
Before you start turn off the computer, unplug AC adapter and remove the battery.
Now I’m going to remove the keyboard.
Carefully insert a small flathead screwdriver under the bezel and lift it up.
Continue removing the bezel with fingers.
The bezel has been removed.
Now remove two screws and release a small plastic latch in the middle.
Lift up the keyboard as it show on the picture and place it upside down on the palm rest.
You’ll find two covers under the keyboard.
Both memory modules are hidden under the right cover. Remove two screws and remove the cover.
In my case both RAM slots are occupied with 512MB modules.
I’m going to remove both modules and replace them with new once.
Spread latches on both sides with thumbs.
The RAM module will pop up at a 30 degree angle.
Carefully pull the module by the edges and replace it with a new one.
Repeat three last steps with the second RAM card.
