What if the power is ON, but the display powers off by itself after a certain period of time?
• Your unit may be in one of several “power saving” modes. • Press any key on the keyboard or move the mouse around. If the computer has been set to standby mode, this action will restore the display. • For DP860, press the suspend button on front display panel. For other units, press power button shortly. This will release the computer from suspend mode. The computer may switch into suspend mode if the display is left on and has been inactive for an extended period of time.
