Opening and Closing the Display

To open the display, slide the display lid latch to

the left and lift up the lid. 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 closing. Do not place any object

on top of the computer when the display is

closed.

The computer has six easy-to-read indicator lights

(LEDs) near the display cover.

even when you close the display cover so you can

closed.
