On the newer laptops I've serviced there is no BIOS reset and pulling the CMOS battery does nothing. I've seen some with what looks similar to solder pads labeled as CMOS reset, but they won't work in most cases.

My suggestion, try the password three times, and a dialog box should pop up with a code. Punch in the code to unlock the bios here...

This has worked on every laptop that I've serviced, even new models. However, if a drive is protected at a bios level, for security, you cannot unlock the drive (this is put into place in case the drive is stolen).
