I have HP Pavilion 4700 series (model #: DV9910US)...
since morning, I am having issues with the machine...
As soon as I boot the laptop, it starts blinking lights on the keyboard (and I can also hear the fan starting)... it starts and then suddenly closes almost immediately and this sequence goes on untill I press Escape key... as soon as I press escape key, lights on the key board stays on (fan also starts) but I don't see anything on the screen, nor any of the key is working... only thing that I can do at this point is to shut it off by powering off the start key...
