Memory (RAM) issue

I have the same problem and the only reasonable solution is to send the unit back to fix the motherboard. I bought two 512 MB modules, installed them both for a total of 1 GB, only to have the machine recognize 512 MB. After swapping the modules around and even depopulating all memory, I found that the slot closest to the front is not working. When I populate a module only in that slot, the BIOS beeps a memory error code when powering up the machine. I've read other posts that claim this is a latent defect in this model. Some folks have even had their T30's degrade to where the once-working front slot no longer works. Hope this helps.

How many RAM slots do you have? Are they coloured differentlly? For example 2 blue, 2 black. If so.. Put one 512 MB DIMM in either a black one or a blue one, and the other DIMM in the other slot of the same colour.

I hope this solves your problem.
