Re: HP 6735B Bios recovery

You will need a good BIOS file and a SPEG to flash the BIOS.

 

Go to this site and post there to see if you can do that model.

To whom it may concern.

 

There are no master password generators for ProBooks or EliteBooks and most business class laptops.

 

You will need to contact HP.

 

http://www8.hp.com/us/en/contact-hp/ww-contact-us.html?jumpid=reg_r1002_usen_c-001_title_r0003

 

Or look at this link.

I have a master external USB HDD with his programs that I have removed hundreds of passwords with Mazzif's help.

 

Mazzif’s program will detect your UUID, Serial Number and model number then use that information to produce an .exe file to clear the password.

 

If you find it to be to technical then.

 

Or replace the BIOS chip.

If you have good soldering skills order the BIOS chip. You will receive a picture of the chips location after purchase.
