my sister gave me her old acer laptop since my lcd screen went out and I want to completely delete and restore the hard drive.

i did it once before on my laptop since I don't have the system restore disks and it basically consisted of holding down a few keys

at the start up screen.

Can ssmeone refresh my memory?

I think possibly you hit F11 52+ times and it will restore to factory settings, but not 100% SURE

sure*
