I have a pair of HP DC7700 's that I'm about to deploy to a computer lab here. Because it's a public lab situation I'd like to prevent users from entering the BIOS. This works fine on one of the machines, but the other won't accept a password. It allows me to enter the password and save and exit the BIOS, but on reboot does not enforce the password I just created.
I've tried restoring factory defaults first, but that didn't help.
Any ideas?

1Did you try unplugging the computer and then checking? I've seen computers with bad batteries which show correct time until they lose power for some time. – AndrejaKo – 2010-07-27T19:05:05.203
