An old laptop I bought (IBM ThinkPad T30) has two memory slots but only one seems to work. When I run a memory test it seems to suggest nothing is wrong. If I put a memory module in the other slot on its own it won't work and the system beeps.

The first slot works perfectly yet I have both slots filled with 512MB and the maximum load is 1024MB.

It sounds like the motherboard is defective.

Have you tested both SODIMMs in both slots? Are both chips identical?

Have you used the IBM diagnostic or something else?

Any sign of damage on the socket?
