Backlight Period

In order to conserve the battery’s charge when you are running your computer without the AC adapter, your screen is designed to go blank after a preset period of inactivity. Initially, that period is two minutes. If you don’t press any key on the keyboard for two minutes, the screen’s backlighting is automatically turned off. To turn it on again, press any key. To do this without disturbing a program running on your computer, press Shift, Ctrl, or Alt.

You can change the period of time the computer waits before darkening the screen to any value between 30 seconds and five minutes, in half-minute increments. You can also disable the automatic screen darkening feature by selecting an unlimited backlight period. To change the backlight period, highlight Backlight period on the setup program’s main menu, then press Enter. The following display appears:

Press the + key to increase the backlight period or the -key to decrease it. To disable automatic screen darkening, keep pressing the + key until the display reads No time limit.
