From: Farao on 30 Jun 2010 18:35 My Dell Dimension 9150 worked well yesterday but today when I turn it on it freeze during the POST, the status bar under the Dell logo on screen go up to 95% more or less, emit a constant beep and the Diagnotic Lights 1 and 4 light up. I unplugged the keyboard, mouse, HD, DVD, monitor and video card and I still get this error. Any idea? Thanks

Chris and William fixed my 9150 by buying a new CR3032 (I think) CMOS battery, and replace the old one, check for battery failure in the event logs if you can get into the BIOS setup, pull all the memory and blow the slots out with compressed air, reseat all the memory, the slots don't matter, but I think they may be matched, e.g. 1-3, 2-4 or 1-2, 3-4. My 9150 only had two sticks of memory, with two open slots. I think we got a bad batch of CMOS batteries, and if the memory slots are left open they get dust and cause a short of some kind. The experts here will chime in if I am wrong. But, that is all it took to get mine back running, and still running ever since. Pat |
