You will need to pull the CMOD battery in order to clear the password if you don't know it.

It says enter unlock password what is it


Acer locks down the BIOS on there computers. The unlock password it is asking for is probably the password to unlock the BIOS. If you do not know what the BIOS is or why you would need in it, it is best to leave it alone and ignore the message. Also, from some quick research, unlocking the BIOS may void your warranty.
