I have a hp paviion note book and i lost thr bios password. how can i get it or how to reset it?

If you have phoenix bios try one of these backdoor passwords:-
BIOS
CMOS
phoenix
PHOENIX

Otherwise let me know which bios you have

u need to dis.assemble ur laptop and short the positive and negative terminal of the cmos battery for 10 seconds.

I have phoenix bios KF_KF.F.19, 05/12/2003. These backdoor passwords don't work. Also, I removed the battery from motherboard for 10 min and put back the battery. Then powered on computer,pushed F2, but it asked me a password again!
