ok you reset your bios by given process

Yet another way to clear the CMOS is to reseat the CMOS battery. By removing and then reinstalling the CMOS battery, you remove the source of power that saves your computer's BIOS settings.

Another way to clear the CMOS is to short the "CLEAR CMOS" jumper on your motherboard, assuming you have one (most motherboards do).

1. Prepare the notebook for disassembly (Section 5.3).
2. Remove the real time clock (RTC) battery (Section 5.18).
3. Wait approximately 5 minutes.
4. Replace the RTC battery and reassemble the notebook.

battery packs at this time.

All passwords and all CMOS settings will have been cleared.

Hi
Sadly there is no easy fix for this, you will be presented with a pass request code when you have tried and failed to enter the correct pass? This requires a response code, which you need to get from HP

How do i remove bios password on my hp 6730s?


On HP DV6000 series laptops, to clear the BIOS password, find the Cmos Battery (or RTC battery) and disconnect it from the motherboard for at least 10 minutes. This will clear the CMOS and clear the passwords. This is straight from the service manual. Once the time is over reconnect the battery and power the system back up, make sure you go right into the BIOS and reset the date and time. This is usually accomplished by striking the delete key or the F2 key during the HP splash screen.
