My grandpa's computer was hit with an HP Assistant Update so he updated it. After the update, it wont boot at all. The computer shows signs of boot up but will shut down after a few seconds, then it will turn it self on again and off again. Can't access bios and any key will not do anything.
I have tried all the take out components, leave the battery out. It was suggested to reset the cmos battery but for some reason I don't think my notebook has it. It had a small button on the back side of the board but I am not to sure if that was it.
I did once get it where the caps lock was blinking. 3 long and 2 short but I do not know how i got to do that.
