Boot/Bios problem

Hello

When my laptop boots, the message "CPU not installed" is displayed (before Windows is loading). When I press F1 I can go on. After that however the message "remove floppy" is displayed, but there isnt any floppy in the disk drive....

All in all very strange things. So maybe a BIOS virus?

I need the laptop for my work, so any help would be greatly appreciated.

More likely your CMOS needs to be reset or the battery replaced.  They're cheap - less than $5, and you should be able to do it yourself.

Resetting your CMOS? How do you do that without having to loosen the CMOS battery?

Well, actually, that's what you have to do with a laptop - remove the battery.  You may need to replace the battery anyway, so try removing it for 1/2 hour first.

Hi,

First try removing the CMOS battery for about an hour, and replacingg it.  If that fails, try flashing the BIOS to a new version... Other than that I wouldnt know.

Good luck.

Thanks all for your input.

But why do you recommend me to remove the battery for about (half) an hour? If I just remove the battery for a second, any viruses in the BIOS's volatile memory will be deleted, not?

Not.  Circuits have capacitors in them, and CMOS in general is designed for low power operation, as opposed to regular RAM, which disappears as soon as voltage is removed.  The two are not the same technology, and you really need to wait longer.
