1. Shut down the computer. If you are unsure whether the
computer is off or in Hibernation, turn the computer on,
and then shut it down through the operating system.
2. Disconnect all external devices connected to the computer.
3. Disconnect the power cord.
4. Remove the battery pack by following these steps:
a. Turn the computer upside down with the front panel
toward you.
b. Slide and hold the battery release latch 1 to the left. (The
front edge of the battery pack disengages from the
computer.)
c. Lift the front edge of the battery pack 2 and swing it
back.
d. Remove the battery pack.
5. Remove the RTC battery from the socket on the system
board.
6. Wait approximately 5 minutes.
7. Replace the RTC battery and reassemble the computer.
8. Connect AC power to the computer. Do not reinsert any
battery packs at this time.
9. Turn on the computer.
All passwords and all CMOS settings have been cleared.

SOURCE: I have forgot my hp compaq nx5000 laptops's cmos addministration password tell me how to refresh my flash bios

Hello
Well having the Nx5000 and running into the same prob I tryed every thing. And figured it out.

Okay to start off you need to unplug the rtc battery located under the keyboard (Please excuss my spelling im just a 15 yr old that cant spell :P)
Continuing
Its a black and red cord located left of the lan card.
Keep it unpluged for 5 mins then plug back in after that keep the battery out and plug in the ac after that power on and then it atomticly save so put the battery back in and your DONE :)
works 100%.

SOURCE: hp compaq nx8220 - Administrator password cannot be reset

If this issue started with a motherboard error that appeared to be a faulty CMOS battery and then it started incorrectly detecting your memory and now is asking for a password it could be a faulty motherboard. If you are 110% you or anyone else has set a password on that laptop then I would say your motherboard needs to be replaced. It is a difficult process to reset admin passwords on most laptops due to a security chip that will prevent the trick of removing the battery from working. In all honestly if no one has set a password and the motherboard THINKS someone has then even if you reset the password you will still have issues. There is a small chance your CPU or RAM could be defective. But, again going back to it saying you have a password set that was never set. It just yells faulty motherboard unless someone has set a password without you knowing.

SOURCE: how can i remove bios password fro hp 6735s

You won't be able to do it yourself. You'll have to contact an authorized HP support center.

There used to be "easy" ways but now the password is stored on a chip on the motherboard.

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

also

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

Hi, Is it possible to reset/recovery admin Bios password on Probook 4310s ? And how, if Yes. regargs, Bob


To reset the BIOS password read the information from this link.

In case of your HP ProBook 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 and I wouldn't recommend doing it especially if it's under warranty.
