This is an obvious question but are you sure your two slots both have a 2G dimm in them? Is it possible that one of them is only a 1G dimm? I myself would be inclined to test each dimm in each slot separately and make sure that each one is seen as 2G by the system independently. (Be careful for ESD damage when handling the ram.) Perhaps you have a bad dimm. Perhaps you have a bad address pin on a dimm slot. If you find that one combination isn't producing a full 2G then you have isolated a problem. If both are 2G in both slots then together the boot time BIOS ram power on self test should report 4G. If not then I think this would be a BIOS problem. You might need to check your laptop's BIOS for updates to see if this is a problem with an update. Other than these things I have no further suggestions. Good luck! Bob
