Hi friends,

i have HP 625 with black screen. I tried to warm up the IGP 216-0752001 and soutbridge 218-0697014 D1, but no effect. I try change the processor and RAM - of course no effect. If i used my postcard, so i receive error "C5P - PnPnd dual cmos (optional), check CMOS baterry or southbridge"

What is mean the error C5P - PnPnd dual cmos (optional) ? Could someone explain it to me, please?

Configuration is:

CPU: AMD Athlon II (AMM320DB022GQ)
IGP: 216-0752001
SB: 218-0697014 D1
IO: SMSC KBC1098-NU
BIOS: SST25VF016B

Thank you for your help.
