you are going to have to unplug the laptop from the wall, turn the laptop over and figure out how to unscrew the keyboard.

Take the keyboard off, find a small battery (looks like a watch battery) take it out for around 5-10 seconds, put everything back together.

This should clear the password

IF the Date & Time reset then the BIOS was cleared. IF it was cleared then this is an ANTI-THEFT BIOS lock -- Contact ACER.
