Hello there
i found the manual for this laptop and it i did a search on the net and everythng that i found is telling me that if you do not have or forgot either your user password or the power on password you are supposed to contact the computer manufacture technical support for password reset instructions
But if you boot into bios you should be able to either disable the password section totally
or simply erase the existing password and if you want to create a new one it will give you the option for this you dont have to enter anything just hit the next or continue and confirm this and than save and reboot the machine ok?
I hope that this is very helpful for you
Best regards Michael

Most laptops do not have one and clearing the cmos will not help.

Contact HP, they have a master password that can get you in. You may have to fax them proof of ownership to get them to help. I had to do this on a laptop.

Hope this helps

Remove the Battery

Remove the Hard Disk

Remove the DIMM Memory from underneath the Laptop and remove the 2x KEYBOARD screws

Turnover laptop and REMOVE the KEYBOARD by pushing back the 4 x Spring clips between keys "esc" & "F1" - "F4" & "F5" - "F8" & "F9" - "F12" & "DELETE"

Remove the 2nd DIMM Memory and Unclip the Battery from Mainboard.

Leave for 30 minutes then start with mains ONLY no battery or Hard Disk

BIOS NOW RESET including Password

Switch Off and now put all back together

I would suggest checking the website of your laptops manufacturer on how to access the BIOS Battery.

When you have gotten to it, remove the BIOS Battery for several (10-20) seconds and then put it back in.
