Question about IBM Computers & Internet
Well, what a mine field!
I found this;
There are at least 9 different R40 Thinkpad models. Look for a label underneath & see if there's a "Type" number...something like 2681, 2682, etc. Once you find the number, go to the following site & select your model/type from the dropdown menu:
And being a 256Mb standard, that may be all it can handle. The above link is rather old but worth a try.
Hope this helps.

Testimonial: "Quick response. Although not quite the response I was looking for it was because I didn't provide enough information, not the responder."
Is Ubuntu installed as a dual boot option.
If so, boot with windows RMB on my computer and select properties. If it gives a reading of 512mb or there abouts, 1 stick is dead, faulty, not inserted properly or the wrong kind of ram.
If running Ubuntu only, click on "Sytem" at the top of the desktop, select "Administration", Select "System Monitor", finally choose the "System" tab. Under the subheading "hardware" you can see how much RAM is running, if 512mb 1 stick is dead, faulty, not inserted properly or the wrong kind of ram.
For the correct type of ram go to the ORCA or CRUCIAL website. Enter your PC details and they'll tell you how much max and what type of ram to install. You don't need to buy from these, but the info is handy.

You can install 128 MB, 256 MB, 512 MB, and 1GB DDR SDRAM DIMMs into the DIMM sockets using the memory configurations in this section.
• Install only identical (the same type and size) DDR DIMM pairs
using the recommended configurations.
• Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table on the next page.
• This motherboard does not support double-sided 16-bit DDR DIMMs.
• Do not create a three-DIMM configuration in dual-channel mode. The
third DIMM is ignored in the dual-channel operation.
