Question about Computers & Internet
Assuming you can get to the CMOS button cell battery, remove all power, pull the button cell out for about a minute, then put it back. The next boot-up should load right to setup, or to an error screen telling that CMOS is corrupt and to run setup.

This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:
I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

I have a HP Compaq nx9010 which has a power on password set.
I origanally knew this password but wanted to remove the need to enter a password at bootup.
I typed in the original power on password and then went into security setting and then entered the old password and then left the new password and confirmation password blank which I though would remove the need to enter a password at bootup.
When I have restarted the laptop I was prompted to enter a password. If I leave it blank it says incorrect password and if I enter the old password it says incorrect password.
I have been in contact with HP and they say removing the bios battery will remove the password but it does not.
Is there anyway of removing this password without having to send it off to HP
Thanks in advance
