-You have a laptop system running Windows 7 with multiple display adapters (2 or more)
-You have set the system to use the external monitor only
After you restart the computer the settings is saved. But when the laptop boots up the next time, the LCD backlight is not turned off.
- Switch the display source to the external monitor through the Windows Mobility Center (or Windows keys – P) from external to internal display and back to external display. The internal display is turned off when output to the external source is reconfigured.
-Connecting the HDMI cable to the laptop computer after booting the computer, or unplugging and reconnecting the HDMI cable if the laptop was booted with the HDMI cable connected.
