Remove the BIOS password for laptop HP Compaq 6520s

Hello everybody!
Notebook is my HP Compaq 6520s. I set the BIOS password, but now I have forgotten it. How can I remove the password now?
Thanks everyone!

I do not know what decade the last replier is from but is most apparent that they can not read the written word... the first person said, that they had a laptop not a desktop... Most laptops that are under eight years old do not have pins to reset the bios... Everything that the replier stated might work on a desktop computer to reset the password.. but since laptops are to easy to steal the companies have made it more difficult to enter the bios and change things when they are password... There are three ways to remove the forgotten password 1 remember it 2 call Hp to get the backdoor password 3 replace the motherboard.. that is it... most of the bios clearing programs are made for dos and will not work with windows above windows 98... xp vista and 7 are NT and will not allow access to the bios..........

How to reset bios password for laptop( HP pavillion zd8060, pr315ua)

I need to reset the bios password for my HP Pavilion Zd8060USA, Part #: PR315UA.

Hi:
Below is the link to the service manual for your notebook.
http://h10032.www1.hp.com/ctg/Manual/c01383095.pdf
Please read the instructions to clear the password in Chapter 1, section 1.2, page 1-4.
Wait 30 minutes, not 5. Five minutes is not enough time to drain the current in most cases.

How to remove the BIOS password on Satellite Pro M10

Hi

thank's
Irwan

Hello Irwan
As you can see there is no much to do and only service can help you. I am really wondering that people here believe that removing CMOS battery will help. It is not the desktop and some things on laptops work a little bit different.
One more thing for you and all people who want to remove BIOS alone. BIOS password removing procedure is not the same for all notebook models. For some models it is so complicated and works similar like on mobile phone. To delete existing password you need to enter special generated code using special tools.
Please contact nearest service provider in your country and they will help you. If the notebook is your private property and if you are owner it should not be the problem.

How to remove the BIOS password on Satellite M40

I'm looking for the the master Bios password or how can I reset the Bios password of Satellite M-40.
I forget my Bios password and I can't used my laptop any more.
Please I need the help

I've got bad news for you... :( the BIOS password cannot be removed easily.
As far as I know only the ASP (Toshiba authorized service provider) can remove the unknown BIOS password...
Therefore I don't see any other solution as to contact the local ASP and to ask for the password removing.
Bye & good luck

There are no master password generators for ProBooks or EliteBooks and most business class laptops.
You will need to contact HP.

Satellite M - How to remove the BIOS password?

Hello.
I forgot my BIOS password. I tried doing everything from introducing some default passwords like 'toshiba' 'phoenix' holding the left shift key while booting to disassembling my laptop and finding my BIOS battery to remove it.
The problem is that my battery is glued on my motherboard and I don't know what to do. I heard that there should be some jumpers near the battery that could help me but I cannont find them.
I am desperated ....what can I do?
please help me
thank you.

Default password doesnt exist and there is no magic default password that can remove existing one. Removing BIOS battery will not help at all. On notebooks it will not work so forget it.
BIOS password can be removed by ASP only so contact nearest ASP and they will help you.
Theory with jumper is also not correct because BIOS removal procedure is not the same for every notebook model.
Sorry but ASP is your only way to remove BIOS password.

Hello farahani hairon nizar,
If your Apple ID was changed from your old account, you may have to change it back to your old account to be able to sign out and then change it back after that is done. Take a look at the article below for more information.

Thats weird because the BIOS or Supervisor password can be reset only by an authorized service provider.
The BIOS password is a high security option which cannot be reset easily.
So ONLY ASP can remove a UNKNOWN password.
