Hello. I just got HP 550 laptop, but it has power-on password. Even if i hit enter 3 times i dont get any code just symbol like this *. I tryed removing RTC battery and i waited for like 2 hrs nothing password is still there. Holding power on button for 30+ seconds with no battery, nope. Im trying to find any CMOS, RTC reset contacts on motherboard but no luck. If any knows how to delete that password please help.
