3TravelMate 230/ 280 Opening and closing the display To open the display, slide the display cover latch to the right 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.
