Opening and Closing the Display
To open the display, slide the display cover latch to the left and lift up the 
cover. Then tilt it to a comfortable viewing position. The computer employs a 
microswitch that turns off the display (and enters standby mode) to conserve 
power when you close the display cover, and turns it back on when you open 
the display cover.
Note: 
If an external monitor is connected, the computer turns off the 
display (but does not enter standby mode) when you close the 
display cover.
To close the display cover, fold it down gently until the display cover latch 
clicks into place.
Warning: 
To avoid damaging the display, do not slam it when you close 
it. Also, do not place any object on top of the computer when 
the display is closed.
