I have been running my Toshiba M--35X-S239 for just a little over three 
years (which puts it ou of warranty) and today when I opened the lid to 
turn it on, the fan came on and I got the  bar across the bottom 
indicating that it was coming out of hibernation, then it suddenly 
stopped, the screen went black and the fan turned off. The power button 
still shows that it is on, and the lights across the front are all on, 
indicating a full battery and tha the computer is on - but nothing else.

I tried to turn it off by closing the lid, but that doesn't work,  Then 
I tried to turn it off by holding down the power button - but it won't 
go off!!
Only way to turn it off is to remove the battery!

Any ideas on what I may do before I take it in to the "Geek Squad". I 
think their standard price is about $90 just to open it up then the 
charges for repair.!!

I might think that it was a bad screen, but it was good and "strong" 
before today, and the fact that I can't shut it down without removing 
the battery makes me think it may be the power control software. 
Warranty is out by a couple of months!! Grrrrrr!!
