Other causes I've found for this issue.
1. Type "bad caps" at google.com
2. I fixed a few by putting in a new power supply.
There is some CMOS RESET or PWD RESET jumpers on boards, which I will not write at length about. I use those to reset the CMOS values and then setup the values again. Rarely fixes the issue.
Worse case issue? The motherboard has failed in some odd way.
I am using this Lenovo PC for some 2 years now. The specs are as follows:
Intel Celeron CPU
Speed 2.66 GHZ
Ram 1.27 GB
MS OS SP2
Bios Type Phoenix-Award V6.00PG
Bios Updated on 11/10/06
Bios ID Grantsdale 6a 79DFKJC-00
At times when I boot up the pc, I would hear 2 beeps and ?CMOS Checksum Error? appears. Then I have to press F1 and reset the date/time and press F10 when I am done. The PC then boots up normally. The next time when I boot up again after switching on the power, the same thing happens. The date goes back to 1/1/2003 and time is 0:0:0. I have to reset this again.
I have tried changing to a new CPU battery but the problem still remains. I have not install any new hardware expect increasing the ram by another 1GB. I have also tried removing the new ram card and conducted an anti-virus scan. Problem still not solved. And the thing that frustrates me is that this happens intermittently.
I have not try the jumpers yet, cause i do not know how or where the jumpers are. Is it necessary to do so? What would be the pros and cons to adjust the jumpers?
Thanks and pls HELP!!!!
