My hp board has a motherboard jumper to reset the bios.

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

Get your HP/Compaq and HP Mini bios master password and Hard Drive (HDD) master password. They also do this for Dell, Acer, Advent, ASUS, Gateway, Samsung, Fujitsu-Siemens and Sony.
Just go to http://www.mastermindit.biz/bios_reset_hdd_recovery.htm...
The Master Password will delete all Bios passwords giving you access to your locked computer again.

I used a program called killcmos and it worked GREAT. I can email it to you, or you can probably find it in a google search. Surefire way to get past the BIOS password.

If it's a Dell NB then the BIOS Password is hardwired via a chip to the MOBO. Call Dell.

I used the killcmos on a Toshiba a215 series. It kills the BIOS, then you reload the BIOS from the manufacturer site, and tada. Worked awesome. Toshiba had quite an issue with BIOS passwords just "assigning" themselves, with no known password (to the user or Toshiba). A lot of their lappys were affected.

^ However, as I stated {I see 1-2 of these/month} if it is a Dell then typically it means a Stolen Notebook and once the Dell goes online {poof lockout}. The Password is a calculation of the S/N; Dell will be happy to provide the P/W to the OWNER.

The BIOS Password, for a Dell, CANNOT be "flashed" away it is a separate chip.

Unless you're out of warranty and they try to charge you, then take any means neccessary... :) 
But I agree, if you can do it through OEM channels, then do so. There is less chance of bricking your laptop with a BIOS flasher. Myself, I was out of warranty and they wanted $45 to pick up the other end of the line. I'll never own a Toshiba again (very happy with my Dell and wife's HP)

Your Phoenix Bios uses a challenge and response method, after entering a wrong password 3 times you will see a system halted-system protected type message along with a 5 digit number, this number is called a hash or check-sum also called an error code. Using this code a master password can be calculated if you know how. The team at www.bios-unlock.com know how, fast and reasonable.
