Abdo Amir wants more answers to this question
Hyghjacked posts, why?
hp probook 4520s Abdo why not ask that at HP dot com and not here.

why ask this on fixya.?

here is the real pages, and anwers
why not get a free account and post there.
the PRO BOOK
is not consumer product
and has BUSINESS Grade , password protection
most need a chip changed out, (by design)
imagine you are CEO of say GM. (full of SECRETS !)
and lost your laptop or was stolen.? stuff happens, right?
do you MR CEO, want that probook hacked, ?
answer is NO, and is part of the reason PROBOOKS cost more.
for SECURITY at this level. (its in silicon this hidden pw , fixed)
but do call HP and ask, never forget to ask the maker direct
and NOT HERE. (we are not HP , not by a 100 miles)

I own an ELITE book and is same deal, (check the new sales prices, see that large price and read the security pages there, yah)

never ever turn on bios password, and lose the PW, write it down for gosh sakes and put the paper in your BIBLE or what eva.
use the cheap notebooks are easy to hack, and all have a back door, yes, but that is what you get for cheap , ALL THAT.

As a laptop repair tech I often get HP notebooks with an unknown bios password and I use http://www.unlockbiosrecovery.com/Unlock_HP-Compaq_HDD.php to get the bios master password for that HP notebook. They make it easy showing you what information they need to calculate your bios master password which deletes any current bios password. I have used them on a regular basis now and they have worked perfectly, if I have a question I just give them a call and a real human answers that knows all about unlocking bios passwords. Only $20 for the bios master password and they guarantee it to work. Only site to order your bios master password from, no scams and real people with real solutions. They have saved me a lot of time and money.

For a probook 4520s. bios user id: 0000 Domain: 0000-HP, Whats the pass word for the bios?

Hello,

There should not be a password set for the BIOS unless you set it. The only way around this is to take the battery out of the BIOS so the BIOS resets itself.

I hope this helps.

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

The 6930p uses the HP Sparekey method of password recovery. The owner sets a password and then completes hints to retrieve it in case it is lost.


They can also register the password with HP and upon providing proper proof of ownership, HP will provide the password the owner registered with HP.


So, if a person can't remember the password or the password hints, they can get it from HP.


If the password wasn't registered, or you are not the original owner, there is nothing you can do to retrieve the password, or clear it.


You will need a new motherboard, or you can strip the notebook for parts (except for the motherboard, which is useless as it is).


Last but not least you can install the Operating System again and this will by pass the Windows password. That would be my option instead of using the computer for a door jam or throwing it out. Just get a System restore disk or another Operating System disk upgrade to Win 7 good software for a laptop.

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.
