SOURCE: How to reset BIOS password

If you really wanted to reset the bios, you have to disassemble your laptop and look for the battery. It is a small circle usually clip with a small metal and soldered. Cmos battery located on the rear of your motherboard. Get the battery using soldering iron or gun, put it back again the battery after 10 seconds. These process will erase all the save information from your cmos or bios. Assemble again and test your laptop. Have a good day!

SOURCE: how to reset the HP

Go to HP's site, look to see if there is any documentation on taking the laptop apart, remove the battery, take it apart, and remove the watch battery found within. Keep it out for a few minutes, put it back, reassemble, and you're good to go.

SOURCE: i need to reset bios administrator password of my hp probook 5310m

If you know the password you can enter the BIOS settings to change the password.. but i stress that you WILL need the current password to do so.

If you do NOT know the current password, you will have to remove the Lithium ION 1.5v battery from the computer, which will require a miniature screw-driver. If you remove the battery for about 30 seconds, the BIOS settings will be cleared to default.

In order to do this I suggest you look up a guide on the manufacturer's website and find out where exactly the battery is housed. It is generally very easy to access the battery, so don't be too scared off by all of the steps provided.

If you are a newer of computer, you can use the bios/cmos password recovery tool from

Wish you luck!

My laptop HP ProBook 4510s prompt computer open password befor going to BIOS or OS. And i don't know what is the password? So how can i reset the password to boot the computer.

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


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
