I'm experiencing a problem with my HP Pavilion DV5 laptop. It will not power on with the charger only. It did so before. It powers on with the battery, but the charger light on the side next to the cable is flashing, and the light that shows that it is on charge is dead.
I tried removing both the cable and battery, holding down power button for 1 minute, then plugging back only the cable, but it won't start. It just starts for half a second, giving some power to the lights and then dead. With only the battery, it starts normally.
The battery hasn't been charging normally for a long time and needed replacement. But, I had it both on cable and battery and it worked with the cable.
I have been running it 5 years on Vista and I recently changed to Windows 7. How can I fix this?
