have a HP Pavillion DV3 that is not powering on.
There is power at power socket and amber light shows when charging changing to a white light when charged. Pressing the power button produces nothing its dead, no lights, no beeps, no fan noises, nothing.
Have removed battery and held power button down for 30 seconds NOTHING
Left battery out and connected power lead NOTHING
Im leaning more towards that its maybe the graphics chip needs reflowing? but my diagnosis is systemboard issue due to the fact that its completely dead.
