BIOS does not have a password by default. However, some users add a security password when setting BIOS. Because the BIOS administrator password is rarely used, it tends to be forgotten after a long time, which leads to that the BIOS can't be accessed. If you do the same, worry not, this article shows you how to remove BIOS administrator password in HP laptop.

  1. Option 1: Temporarily Remove the CMOS Battery
  2. Option 2: Remove HP Laptop BIOS Password on freeDOS

Option 1: Temporarily Remove the CMOS Battery

If you have the tools and are familiar with laptop disassembly, then you can delete the forgotten BIOS administrator password by removing the CMOS battery. This is a traditional and effective method, but you have to be careful during the process to avoid damaging the hardware.

Note: This method will not only remove the password, but also the entire BIOS setup.

Step 1: Turn off your HP laptop and make sure to disconnect all external power sources.

Step 2: Open the bottom cover of the laptop, find and remove the CMOS battery (it looks like a coin).

Step 3: After removing the battery, wait for a few minutes to make sure the BIOS settings are cleared.

Step 4: Reinstall the CMOS battery, reassemble the laptop and reboot the system, then you can reset and access the BIOS now.

Step 3. In freeDOS, use the commands of cpqtag.exe to clear all the data of BIOS and set the information of mainboard.

1. Restart computer and press F9 key, select the USB drive as the boot drive to enter FreeDOS, and then enter the command cpqtag write defaults to clear all the data of BIOS.

2. Commands of setting the information of the mainboard:

cpqtag write model "HP EliteBook 8530w"
cpqtag write sku "FM880UTR#ABA"
cpqtag write serial "USH93000WC"

Or you can use Hpset152 -r command to select the profiles you just backed up using Hpset152 -s command to restore.

Important: After restart, the BIOS password has been removed, but you may find a red warning in the upper left corner of the screen like: WANING!!-Machine is not in committed state! This is because there is not vPro status on the computer.

A method to remove the red warning:

1. Run CPQTAG in FreeDOS. Command: cpqtag read VPRO.

2. Check the output results. Generally, the computers that have not activated vPro will display the following message:
VPro Enable
Descriptor locked
DesManagement Engine enable
Flash Protection Override disable

3. Unlock Descriptor locked. Before doing this step, you need to shut down your computer. It is better to unplug the power supply and battery and then connect them again after 5 seconds.

4. Press Win, and key simultaneously and don't release, and then press the power button to boot. You can release the three keys after starting.

5. After boot, press F9 to select the USB drive to enter FreeDOS, run CPQTAG in FreeDOS, and then enter cpqtag read VPRO again. The following message will be displayed if successful:
VPro Enable
Descriptor unlocked
DesManagement Engine enable
Flash Protection Override disable

In short, the word behind "Descriptor" should be changed to "unlocked" but not "locked".

6. Enter the below commands one by one to remove the red warning:

cpqtag write vpro reset
cpqtag write vpro on
cpqtag write vpro lock
cpqtag reboot vpro

The red warning will be removed after restart.

Note: If the word behind "Descriptor" is "locked" but not "unlocked", you should repeat the third and the fourth steps until successful.
