There are no master password generators for ProBooks or EliteBooks.
You will need to contact HP.

First, is the password in the bios or in the windows startup screen?

If it is a windows password issue the only way I am aware of (that may work) is by using the info at the link below.

I have personnally and successfully used this solution. Howerver, it is a bit technical.

I hope this helps you.

Good Luck!

HP Support can create a bios master password for you that will delete any currently set bios password. You can also use http://www.unlockbiosrecovery.com/Unlock_HP-Compaq_Bios.php and for $20 they can create the same bios master password that HP Support would give you and they guarantee it to work.

remove the BIOS battery and insert .so that BIOS password will get reset

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.
