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.

you need to consult the customer care support line for HP on the bypass password. sometimes they might have to replace your bios.

Inside of the computer you will see a small yellow(likely) button. Press and hold for about 5-7 seconds and then try, This is the CMOS reset button.
