CMOS battery

retsel25 · 03-28-2009, 11:01 AM

Hi I'm getting this message each time I turn on my laptop:

cmos checksum invalid

and I google the problem and most of the sites say its faulty cmos battery. My question is: where is the cmos battery located and what kind.

any assistance is appreciated.

AFAIK it is located in the motherboard. Get a service manual for your brand/model to help you locate exactly the CMOS. The manual may help tell you also what kind of CMOS battery you need.

if you post the exact laptop model you have, maybe someone here can give more specific help.

Sorry about that, my laptop is SEANOTE XP HOME with Sin number:N18803

I HOPE THATS GOOD ENOUGH INFO.

Download a service manual to guide you for the location and replacement. Try the Seanix website may be they have it for download like HP/COMPAQ, DELL and IBM.

EDIT:
I checked with Seanix website and it is not much of a help. No hits in Google. I suggest you contact Seanix as they do not have any information available publicly.
