HP Pavilion dv4 won't boot; blank screen

So yesterday I was using my hp laptop just fine.  However, the ac plug was loose and so I was running only from the battery.  I guess the battery ran out and I was unaware of this, so the laptop just completely shut down.  So i plugged the ac cord back in and pressed the power button.  But now the screen doesn't show anything.  All the lights are on and i can hear the fan.  However, the volume light and the internet wifi light is orange which is usually the case when the computer is hibernating.  I kept trying to restart it over and over and sometimes the screen will turn greyish so I know the LCD screen isn;t the problem.  Any ideas?

Have you tried removing the battery to see if that clears it up?

Perform a hard reset on the Notebook. To perform a hard reset, follow the steps below.

 

  1. Unplug the AC adapter from the notebook PC.
  2. Remove the battery from the notebook battery compartment.
  3. Disconnect any external devices or peripherals connected to the notebook. Press and hold down the power button for about 15 seconds

My dv4 is doing the same thing, come on HP - {Content Removed: legal discussion}Apprarently one of the chips on the motherboard heats up and causes the solder joints to disconnect. This happened with Nvidia chips and HP and a class action forced them to repair or replace the laptops - or refund the users if they paid for a repair. I WILL NOT PURCHASE OR RECOMMEND ANY HP PRODUCTS UNTIL THESE QC ISSUES ARE RESOLVED.

{Content Removed: legal discussion} My piece of junk dv4 just got itself stuck with the same problem.  Flashing caps lock and scroll lights, fan running, no screen.
