memory problem with Thinkpad 600E
Posted: Sun Jun 05, 2005 5:02 pm
My IBM Thinkpad 600E (type 2645) has 32mb of onboard memory. I recently installed two 128mb/pc100 chips. Buy only 164mb is recognized. To mess around, I removed a 128mb chip out of bank 2, and left a 128 in bank 1, laptop only recognizes 32mb onboard memory. I also tried installing a 64mb/pc66 chip in bank 1, it is still not recognized. This laptop is supposed to recognize up to 288mb of ram. Does anyone know what the problem could be? Do I have a bad memory bank? I ran a memory test in the bios which concluded that everything was o.k.. I am at a loss as to what to do next, if there is anything I can do. Any help would be appreciated.
p.s. I also removed all power sources during attempted upgrades.
Thanks
