bois screen lost after cmos battery discon

Friend has given me a ZDS VESTA SX laptop to try and fix.On boot up and even after pressing F2,it was asking for "the CURRENT password".On advice after looking through postings on here,I disconnected the CMOS battery overnight.Now when I boot up,there is no picture at all,not even the password request.I can hear the fan running so at least its starting up .How do I get the bios back ? . (Zenith Data Systems were taken over by Packard Bell round about the time this machine was made so support for it is hard to find).Cheers all.

Will it boot into Safe Mode (usually F8 on boot)?

No it doesnt Graham.. Mibbe its me guessing,but it would appear the bios has been totally lost.Just wanted to know how to download the bios (if I can find it ) and reinstall

Unplug the power supply, take out the main laptop battery so it has no power.

Press the start button for 30 seconds, connect power back up and try.

Sorry Norm no joy.. this is an ancient lappy and probly due for the square window..just hate these buggers getting the better of me

I am clutching at straws.

Could it be the laptop is looking for the recovery disk? Or is there a jumper you have to move to reset the CMOS?

Another long shot, my first lappie would occasionally lose its brightness and contrast settings and the screen would appear blank. Fiddling with the appropriate controls would restore things.
