If the battery won't come out then check out this website, they seem to have good tools: http://www.dewassoc.com/support/bios/bios_password.htm

Otherwise try sending your computer back to Compaq/HP if it's under warranty. 
I'm sorry I couldn't help more...

Compaq presario r 30000 need to bypass power on password    password is not working . need to restore to factory setting


Power On The Power On password is set in the System BIOS options. It prevents unwanted users from accessing the computer. By default, HP does not set the Power On password. If you set the Power On password in the System BIOS options you will be prompted for it immediately after you power on the Notebook PC. If this password is forgotten, a repair at an HP certified repair center is required to reset the computer. Please contact HP to schedule a repair. This service is not covered by the warranty. Drive Lock The Drive Lock password protects the data on your hard drive through encryption. If your computer is stolen, the data on the hard drive is inaccessible without the Drive Lock password. This password cannot be reset. If it is lost or forgotten, the hard drive must be replaced. Please contact HP to order a new hard drive. This service is not covered by the warranty.

How to resets bios for compaq 2514 at


Why? What happend? Is it asking for a BIOS password?
If it is asking you have to short two jumpers on the systemboard to have it reset.
If not, just go in to BIOS by pressing F2 then restore or optimize default settings on BIOS.

Hope this helps...
