My HP Pavilion DV7 1261WM will not turn on. Was using it last night and turned it off. This morning it came on for about 5 seconds and shut off never to come on again. I followed the instructions here for a hard reset and it comes on for about 5 seconds, enough to light up the keyboard and then shuts back off. Every time I perform the hard reset it works for 5 seconds and then shuts back off.
What is the solution please? Dead battery? Thank you.
I notice that during the 5 seconds of attempting boot up there is no power light where the AC cord plugs into the laptop.
