Hi
I'm working on a:
HP Pavilion dv9610us laptop
Nvidia chipset
Nvidia video
windows 7-64

I guess this deals with interal & external. When I turn it on sometimes the display comes on and sometimes it won't.
I then have to do any combintion of the following. Turn it off, take out the battery, hold down the power button for 15 sec
for a hard restart, try to restart with battery out on AC, restart on battery no AC or with battery and AC.
I have flashed the BIOS to HP's current for this model, updated the Nvidia drivers (HP's)and run all the Windows 7 updates.
There are no perifreals pluged in. I have diabled Sleep mode, set hard drive idle at 300 min. One or two times it would not come
back after it went to the screen saver The fan is running and the temps are: (using SpeedFan)
GeForce Video 140f this may be an issue but it does it when cold also
HD 104
ACPI 127
AMD K8 104
this program won't show me fan

Any help with this would be appreciated

I would advise you hook up a monitor to the VGA-out port on your laptop. (this is a blue coloured port
on the side or the back of the system). Having an external monitor plugged in will give you a better idea
if your inbuilt screen is Ok or not.

Hope this helps!

Hooked a external monitor worked fine. Figured out it's the LCD invertor
