I just picked up (part of) a HP Pavilion 6830(KR) (P 2937 A), a few days ago... It was a "dumpster dive" find, that was just the case, and mobo.
It's got an Asus mATX board in it, that I can find little info on anywhere other than HP's site itself. HP shows a mobo layout jpeg of the board that "supposed" to be in it (an Asus CUW-AM), but the board I have is slightly different.
Anyways...it's (was) a Celeron700 system, that originally had 64MB SDRAM, a 20GB HDD, and a 40x CD-ROM.
I put my old C366 in it, and 128MB of PC133, and it booted! But.... The RTC (Real Time Clock) is way, WAY off... It runs at two or three times the correct speed. What I mean by that is, as you watch the clock in the BIOS, it'll tick off 60 seconds in around 20 to 30 real time seconds.
Once I got into Windows, it would display the correct time and speed, if I set it in Windows, until I reboot. I had it running for about half an hour (real time), and when I rebooted, the clock in Windows jumped ahead over an hour.
I cleared the CMOS, and flashed the BIOS, and neither fixed this. I also replaced the CMOS battery (twice) with known good ones... I'm assuming that this is why the thing got thrown out.
Is there any way to repair this, or is the mobo toast? Everything else (onboard sound, vid, etc...) works great...just the clock is royally screwed up.
TIA!!
