Instructions
http://www.wikihow.com/Disable-BIOS...
1: Turn on your computer and press the key needed to access your computer's BIOS. "F2," "Del" and "F12" are common keys, but this varies for different manufacturers.

2: Use your computer's arrow keys to access the "Advanced" menu option. Select the "System BIOS Shadowing" option and press "Enter." Select "Disabled" from the options that appear and click "Enter."

3: Use your arrow keys to select "Exit" and choose "Save and Exit" to save your settings

When you took the main battery out (disconnected from power I hope) did you hold the Power Off/On button down for at least 20 seconds? If not do this, it discharges the motherboard and has been known to fix the symptoms you are having - at times.

See also the options here:

Have you always had to enter a BIOS password? Try just hitting Enter key instead of a password. Back tomorrow sometime - way past bedtime (I'm in UK).

Always pop back and let us know the outcome - thanks

"would not except the password"
Did you try without a password?

Did you know there was a bios password but when entering it it's not being accepted or is the bios password something new? If the former take care with upper and lower case letters. If the latter ask others who have used it recently if they set a password.
