When the display goes black, try looking at it at an angle to see if the
display is still functioning or not. I had a similar problem with an
Averatec laptop when the backlight would go off due to an intermittent
connection in the cable from display to body. Do try to determine if there
is any function in the display or not, even with the backlight off.

Your "Kernel power event ID 41" means that you rebooted without a clean
shutdown. This is when you have to reboot due to a blank screen and does not
indicate the cause of the blank screen.

Subject: Dell Laptop shuts off spuriously.

I have a Dell 17R 5720 Laptop running Windows 7 pro, i7 Intel Mobile, 8 GB
Ram, 1TB hard drive, and integrated intel graphics.  I bought it just this
way about 4 yrs ago and it has been running good up until the current
hiccup.  What is does is just turn off to black screen while I'm using it.
Sometimes it clicks once (could be hard drive seating?), but I am hard of
hearing, so maybe clicks everytime.  It doesn't seem to happen consistenly
doing any one thing like videos.  If I play videos consitently to check out
if it is overheating, the fan cycles on and off blowing warm air.  I lifted
the keyboard to check fan movement and it is moving.  The event logs for
this time shows a critical error.  Kernel power event ID 41.  I have taken
it apart to look at the system board under bright light, but have not been
able to see anything like burn spots or puffed up capacitors.  I haven't
taken the heat sink off yet since I don't have any thermal compound, but I
think that could be next when I get some. The laptop is currently back
together and is doing the same thing.  PC doctor doesn't find anything on
extended memory and
drive tests.   Does anyone have any ideas or experience with this or
similar?   Thanks  George.
