Having problems with your PC Desktops ?

Fujitsu Seimens Laptop V2030. I have removed the 2030 disk shaped cmos back up battery placed under sticky tape and replaced with new. The computer will now not boot up. I have power to the fan but no screen. is there a lock that I have to remove through the keyboard settings?

Answers :

Changing this shouldn't cause or harm it at all. except if you change it the wrong way it could burn the bios chip's internal blocks.

1. remove the battery, + big battery + ac charger
and wait 15 minutes, then boot.

2. try booting without the cmos battery

3. try swapping the memory

why did u change it in the first place?
