How to remove forgotten power on password on hp 18'' all in one desktop pc


If I understand correctly, you are referring to a password that is set in the computer's BIOS which comes before the operating system (Windows / Mac / Linux) starts.

Most BIOS passwords can be reset using a jumper on the motherboard. This is where it gets very specific to the motherboard so you should look for documentation on your specific HP model at support.hp.com.

Typically, you move the CMOS jumper to different pins, power on the system and when the POST completes, turn it off, move the jumper back to its original position, and the computer should start without the "power on" password. In short, it removes whatever changes were made to the BIOS.

I hope this helps.

How do i locate the hp probook 4520s BIOS password jumper on the motherboard


4520s.
you failed because of one reason, you asked on fixya not HP'
why ask here, there are no HP(few) folks here, they are all over at HP, real forum.?
bios resets are tricky,
the new rules changed with UEFI BIOS and or TPM chips added.
back in 2007 the mobo had reset jumper, (mine desktop does)
but not my 2008 elitebook laptop, due to the TPM rules.

first the link to your books
https://support.hp.com/us-en/product/HP-ProBook-4520s-Notebook-PC/4145198

those cover most issues, you will have. all by HP direct,
page 126 here is not too clear;.
the answer is here
your PC is fully locked now, there is no way to reset it .
without HP direct intervention (fixya can never ever do that)
the send you a special binary flash file that only works on YOUR PC (a fact and is by DESIGN)

https://h30434.www3.hp.com/t5/Business-Notebooks/Probook-4545s-Bios-Password-reset/m-p/6350164#M147169


never use a BIOS password, unless you write it down and hide the paper in a book you know, where it is. (got books?) i know books are now (dead technology but)>?
if you guess and start flashing BIOS, you will BRICK THIS PC.

Where dos jumper located on compaq 6910p and how can i remove bios password on 6910p


Most "laptop" computer do *NOT* have a jumper that can be used to bypass a BIOS password.
This is DELIBERATELY done, so that a thief in possession of your laptop cannot bypass your password, and thus cannot use your stolen laptop.

Find your original bill-of-sale, to prove ownership, and telephone HP/Compaq, and ask for Technical Supoprt in resetting the BIOS password.

Hp probook 4310s bios password reset pls


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

In case of your 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.

Hi,

There are four common categories of solutions to remove or reset a BIOS password and here are the details on how to go about resetting your BIOS password.

Manufacturer Backdoor BIOS Password

Most of the BIOS makers have set a backdoor password on the older computer models. That is the master password for BIOS. To reset BIOS passwords first you need to check the manufacturer of your computer's BIOS. Most computers have BIOS include AMI,
IBM, Award, and Phoenix. These are the most common BIOS. You can unlock your locked BIOS using this master password. It works, no matter what the user sets the password to. Many popular computer and laptop manufacturers such as HP and DELL lock the BIOS because they want to protect their machine's most sensitive areas (those areas which have warranty) from their customers. These passwords are usually used by computer technicians for testing and repairing.

Reset the jumper that holds the password

Open the computer and locate on the motherboard the BIOS password jumper. The jumper is usually jumper 1 and often labeled as PSWD, PWD, CLRPWD, CLEAR, JCMOS1, CLR, CLEAR CMOS, PASSWD, or PASSWORD. Normally you would have 3 pins and to reset the password you just need to put the jumper on the 2 and 3 pins leaving pin 1 empty. After you move the jumper, turn the computer on to clear the password, then once password removed turn it off and put the jumper back to its original position.

Removing the CMOS Battery to reset the BIOS to default

Switch off your computer, and open up the case. You'll see a circular metallic silver item on motherboard. This is called CMOS Battery. Remove it carefully, and leave it out for about 2 minutes. This act will remove the CMOS memory which contains BIOS password. Set the CMOS battery back and switch on the computer. Restore the CMOS configuration as default. Your BIOS password has been cleared now.

Using third party software utility to reset BIOS password

To reset BIOS you can use third party software like Kill CMOS which wipes out CMOS, or CmosPwd which is a BIOS utility. Hiren's Boot CD has a few programs including the above two that will help you to reset the password. Here is a link to Hirens Boot CD website http://www.hirensbootcd.org/. To download the latest version, click on the Download link on the left side and go to the last page. You will need a CD writer to put the content on a blank CD.

Please let me know whether this works or not.

In do not know the biao password of my HP 5100 ssf


Since it's a desktop computer, there is a small 'jumper' on the motherboard that can be accessed.
Turn the computer off.
Disconnect the AC power cable.
Remove the side-panel.
Look for 3 gold pins in a row, labelled 'BIOS reset' or just 'reset'.
Move the jumper from the 1-2 position to the 2-3 position.
Wait a few seconds.
Move the jumper back to the 1-2 position.
Replace the side-panel.
Reconnect the AC power.
Restart, and enter BIOS SETUP.
Use 'LOAD BIOS DEFAULTS'.
Done.
