Brazenly OT: ThinkPad760XL local/v/remote screen

[David Betz]

If the screen works during bootup but then stops working once the OS is 
loaded, you might check to see if the little switch that detects 
whether the screen is closed is stuck. That happened to my Dell laptop 
and it would only work with the external monitor. Apparently, the OS 
thinks that the laptop is closed and shuts down the LCD.
