I have a HP DV4-1225dx laptop that the screen would flicker while booting up into Vista. I would be able to get as far as the login screen sometimes and the screen was visibly flickering with hard drive activity. After a minute or so, the laptop would instantly power off. This happened to me several times. This happens with the charger plugged in to the laptop.
So, I left the charger plugged in to the laptop to make sure the battery was fully charged (charging light came on), got home from work and went to power the laptop up and nothing at all.
I tested the power supply with a multimeter and I am getting good readings. I am having problems testing the battery as the contacts are too small for me to get my multimeter probes into. I used aluminum foil to get to the contacts and get my probe attached to it. I am getting nothing. However with a netbook battery I tried the same rig and got nothing when probing it either. Am i doing something wrong?
Does this sound like a battery problem, mobo, or something else?
