M10000 CMOS battery every 3 weeks?

Davefocus · 10-10-2009, 02:32 AM

My M10000 was great for about a year (got it second hand so longer thnn a year). The CMOS battery needs chaning every 3 weeks now, or more to the point I get an error message to says 'CMOS defaults being loaded....F1 to continue DEL for setup', so I end up changing the CMOS battery and re-setting the BIOS.

Relevant other information. About the time I changed the CMOS battery the I tried hiberation in RR to see whether this would improve boot time, but didn't significantly, so went back to shutdown, as before. I also started using the interal USB header for more USB devices.

I can't think why the CMOS battery appears to be draining so quickly and losing the BIOS settings? Any suggestions?

Thanks

This one is tricky. Im assuming you are using new batteries each time. Is it very cold? Try resetting the BIOS using the jumpers before putting in a new battery. It could be that the motherboard has a short circuit somewhere, maybe try wiping down the motherboard and the battery connector? Do you see any corrosion? I suppose if nothing else works then you can strap on some AA's or have a regulated 3V supply direct from your main car battery.
