To reset the BIOS read the information from this link.

In case of your HP laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

I don't have a password for the set up utility screen!


BIOS password to enter set up?

When you boot up to the log in screen type in administrator as user to log in if you cant log in

during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there


if no luck with this

The most common way that we know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing the Cmos battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased.

Hope this helps you

The BIOS and Supervisor passwords cannot be removed or changed unless you know the existing password(s). If you forget your BIOS or Supervisor password, you will have to have the password removed by a Toshiba Authorized Service Provider

Toshiba a120 bios password


It cannot be removed using software.

To remove the password you will have to remove the CMOS battery located on the lower side of the motherboard.

To access the battery the computer must be disassembled completely.

Bios defult to erase system passowrd


You can only change supervisors password in BIOS by entering blans(spacebar) to reomove that password but you cant change your windows password. For that you will have to login with a different user and then delete/change the earlier password. Other repair the OS from its original disc and make sure where you enter the passwords....Do not try to add supervisor password in BIOS, thats very deceptive....sodeep
