My Pavilion laptop has started to fail at times when I boot it up, all that happens is I get a blank screen and my power button pulses every 3-5 seconds. Additionally, when it's working and I disconnect the power cable it crashes.
The pulsing indicates the battery is low and is being charged; the power off means is it too low to run the laptop. My guess is that it is not holding a charge and will need to be replaced.
I am a volunteer and I do not work for, nor represent, HP
