Having problems with your IBM ThinkPad T40 2373 Notebook ?

I can only find one slot for a RAM module, under the memory bay door on the bottom of the machine, but the Crucial site says there are two slots. A system info readout for it says I have 512 of RAM but the module I find is only 256, so I suspect there's another module somewhere but don't know where. I want to upgrade the to 2048 using two 1024 modules, but won't order them until I know where to find the missing slot. Help!


Answers :

The other memory slot is under the keyboard. Below is the service manual that has the full disassembly instructions for thelaptop. You can see the memory module installation on page 83. Just follow the guide on keyboard removal, the slot will be visible when the keyboard is removed.
