Compaq 610 Notebook PC BIOS password recovery/reset

[Ryan_HP]

Hello,

I bought a Compaq610, and i'd like to update its bios. I downloaded the updater, but it required the bios password and I don't have it.

May I kindly ask if there is a way to recover/reset or delete the passoword?

Many thanks.

Best regards,

Ryan

If you enter wrong password 3 times- or just leave it blank & hit enter 3 times you should get a message about "System Disabled" and a halt code. Post the code here.

If you do not get a halt code-then the answer is no backdoor password for this model.

How to reset your laptop BIOS or CMOS password ?

You can reset the bios password by different backdoor tricks. Here’s a list of backdoor tricks:

1. Reset by backdoor passwords
2. Reset by software
3. Reset by bios jumper and solder bread
4. Reset by C-MOS battery

Reset by backdoor password –

There are some of backdoor passwords which the bios manufacture company creates to open the bios menu in case of customer forgets our own password

Resting by password cracking software -

We can also remove the bios password by the cracking software’s like “Hirens.BootCD.15.2.zip”. We also use Hirens Boot CD because it’s bootable software which contains numbers of diagnostic tools and a live operating system.

Resting by bios jumper and solder bread -

You can also break the bios by CMOS jumper. Shorting the jumper till 20 sec can reset your biospassword. Mostly the bios jumper (solder bread) located, nearest by the ram slot or the CMOS battery.

Resting by C-MOS battery – 

All the cmos and bios setting is saved in the bios chip which was attached on the motherboard. The main work of cmos battery is giving a continuous power supply to the bios chip to save all the settings. If you unplug or remove the battery for above 5 sec, the bios setting will be reset.

Hi @jimmy0385,

Welcome to the HP Forums 🙂

I would like to take a moment and thank you for using this forum, it is a great place to find answers.

As I understand there is a message - "Bios Password" on your screen and you need assistance with the same,

You would have to contact HP phone support for a hardware service as the motherboard may require a tattoo/Bios Flash.

Any other way of unlocking the BIOS is not authorised by HP.

Keep me posted,

Hi @jimmy0385,

Thanks for the update,

I see from the previous post that you are getting a message "Power ON Password" message on your screen. In this scenario, the only option would be to tattoo the motherboard or flash the Bios, now this can be done only in the HP service center. Any other way of unlocking the Bios is not authorized by HP.
