Re: "power on" password

A "Power On" password is set up in what's called the BIOS. This password is a serious one, in that without the correct one you cannot ever use your machine. If you have lost your power on password, you may have to reset your BIOS by removing your onboard battery. Keep in mind if your computer is still under warranty it is advised you contact HP technical support. 

 

Be aware, in most cases not knowing your power on password will leave the computer inept.

 

Have a better day,

Re: "power on" password

Hi:

 

If you want to remove the power on password, if removing the battery doesn't work (and that method will NOT work on HP business PC's), there is a green jumper on the motherboard that you have to remove.

 

The procedure is as follows:

 

Resetting the Password Jumper
To disable the power-on or setup password features, or to clear the
power-on or setup passwords, complete the following steps:


1. Shut down the operating system properly, then turn off the
computer and any external devices, and disconnect the power
cord from the power outlet.


2. With the power cord disconnected, press the power button again
to drain the system of any residual power.
WARNING: To reduce the risk of personal injury from electrical shock
and/or hot surfaces, be sure to disconnect the power cord from the wall
outlet, and allow the internal system components to cool before touching.
CAUTION: When the computer is plugged in, the power supply always
has voltage applied to the system board even when the unit is turned off.
Failure to disconnect the power cord can result in damage to the system.
CAUTION: Static electricity can damage the electronic components
of the computer or optional equipment. Before beginning these
procedures, ensure that you are discharged of static electricity by briefly
touching a grounded metal object. See the Safety & Regulatory
Information guide on the Documentation and Diagnostics CD for more
information

 

3. Remove the computer cover or access panel.


4. Locate the header and jumper.
✎ The password jumper is green so that it can be easily identified. For
assistance locating the password jumper and other system board
components, see the Illustrated Parts Map (IPM) for that particular
system. The IPM can be downloaded from www.hp.com/support.

5. Remove the jumper from pins 1 and 2. Place the jumper on either
pin 1 or 2, but not both, so that it does not get lost.

6. Replace the computer cover or access panel.

7. Reconnect the external equipment.

Password Security and Resetting CMOS

8. Plug in the computer and turn on power. Allow the operating
system to start. This clears the current passwords and disables the
password features.

9. To establish new passwords, repeat steps 1 through 4, replace the
password jumper on pins 1 and 2, then repeat steps 6 through 8.
Establish the new passwords in Computer Setup.

Re: "power on" password

When your computer wakes from sleep, or is turned on, no one can access it without enter the correct password to unlock the computer.  This is usually referred to as the "power on" password or "CMOS" password.  If you set a "power on" password it is very important to NOT forget it. Resetting the "power on" or "CMOS" password usually requires opening the computer and manually resetting jumpers or removing the battery. Check the documentation that came with your computer, if you need to reset the jumpers.
