CMOS error?

Postby cncnb on Sat Oct 16, 2004 8:50 pm

I have a HP Pavillion XL866 I used in our office, no gaming just record-keeping. It began to restart itself if more than one operation was running so I cleaned it up and blew it out. I found the cpu fan had gone bad. I changed this part out and also replaced the larger fan in the housing(it was running but noisy). When I restarted it the set up screen gave the following message:

0251-System CMOS checksum bad-Default config. used
0271-Check date and time settings

this was followed by a message to go to F1 or F2
the system froze at this point and will not go any further.

Is there a quick fix for this or do I need to change out the cpu since it may have overheated and gone bad?
Thanks in advance for any information.

The battery for the bios chip on the board may have died cuasing the error. I spose it may also cuase it to not boot if the chip can't even remember default settings. I'd check the battery first as it should be cheap and easy to replace then if it doesn't work try the cpu. If that doesn't help start pulling things that might have died one at a time and you might get to the problem, good luck.

Thank you. I'll try that first. If it looks like its going to be something else, this may be a good time to think about building a new one.

That would be a good bet. You can pick your own parts and have better upgradability, and probably do it cheaper as well.
