deleated bios?

[acprkit]

Hi

I have an ibm thinkpad x23, and shut it down about an hour ago. When I
went to
reboot , all the lights come on then they go off and only the light
with the z in a circle stays on. The screen stays blank and the hard
drive spins. Could I have deleated the bios when I added memory
(shocked the motherboard?)



Thanks for any help!
