Answer» HI. I ve a NEC versa pro VA12J. When i START my laptop it starts with beep sound and shows BIOS screen with an error message: 0251: system CMOS checksum bad- DEFAULT configration used. During this period, my processor fan runs very fast.In BIOS only time and date are incorrect. After changing the time and date when i save the setting it appears a black screen like it is checking drives, but suddenly my laptop goes off. I ve checked my HARD DISK in an other laptop it works there, so what's the problem?Sounds like the CMOS battery needs replaced.....part #CR2032....available anywhere. |
