Hi,
I have a HP dc7600 Small Form Factor desktop. I need to reset it's Bios password as i have forgotton it. I tried by removing the motherboard battery with the power cord disconnected for more than 24 hrs. Also booted the computer with the battery disconnected for more than 15 min. But the password remains.
Need your help.

Hello faizi. Try this:

You might need a second computer for this

And next time, apply the password on Windows, not on BIOS :)
(because password cracking on windows is relatively easier)

@Mods: Sorry, but its from Lifehacker, so it isn't hacking. But delete it if the link isn't OK...

From HP's website http://h20000.www2.hp.com/bizs.....0405101#A1

Resetting CMOS
Configuration settings for the computer, such as system passwords and BIOS values, are stored in CMOS memory. Occasionally, CMOS may be corrupted, usually due to improperly functioning software or hardware, or the addition or removal of expansion boards. If CMOS is corrupted, you can clear it and reset it to its original (factory) configuration. This resets the software settings that include the boot sequence order and other BIOS values. It will not, however, force hardware rediscovery.
NOTE: Resetting CMOS clears any current passwords and resets them to the factory defaults, which are null.
Resetting CMOS on the System Board
To reset CMOS using the CMOS reset switch:

* Power off the system.
* Disconnect and remove the AC power cord.
* Remove the access panel.
* Locate the CMOS reset switch on the system board.
* Depress the switch for 3 to 5 seconds.
* Replace the access panel.
* Reconnect the AC power cord.
* Power on the system.
