20124. How To Adjust The LCD Brightness On Your Notebook (Windows 7)


STEP 1. Adjusting & Maintaining The LCD Brightness On Your Notebook


At boot up, by default, the LCD brightness of your notebook is at its brightest (Level 8) if you've connected the notebook to the AC power adapter. It becomes dimmer automatically if your notebook is running on battery power to conserve energy.

For notebooks with an ambient light sensor, the ambient light sensor detects external, ambient illumination and automatically controls the LCD brightness accordingly. However, the ambient light sensor only works when the computer is operating on battery power.

Adjusting the Brightness Level

Note: If you do not have Samsung Easy Display Manager installed, you will not be able to adjust the LCD brightness as described below. To adjust the LCD brightness, you must use the Power options instead.

Increasing and Decreasing the Brightness Level

Press the Function key and the up arrow to increase the brightness level. LCD brightness has 8 levels. Each time you press the up arrow, the brightness increases by 1 level.

Press the Function key and the bottom arrow to decrease the brightness level. The on screen LCD indicator appears briefly on your LCD screen, showing the current brightness level.

Maintaining the LCD Brightness You Set With or Without the AC Adapter Connected

To maintain the LCD brightness you've set with or without the AC adapter connected, follow these steps:

  1. Turn the notebook on, and then press the F2 key when the SAMSUNG logo appears on the screen to enter the BIOS setup. The BIOS setup screen appears.
  2. Use the right and left arrows on your keyboard to select the BOOT menu.
  3. Use the down arrow to highlight Brightness Mode Control, and then press Enter. Two options appear:
    • Auto: The Brightness values are set by the status of the AC adapter at each boot up.
    • User Control: The Brightness values you set remain regardless of the status of the AC adapter.

    Note: Regardless of which option you choose, you can still increase or decrease the brightness by pressing the function key and the up or down arrow key.

  1. Use your up and bottom arrows to highlight User Control, and then press Enter.
  2. Press the F10 key to save the settings and exit the Boot menu. A Setup Confirmation screen appears.
  3. Use your right and left arrows to select Yes, and then press enter. Your notebook restarts.
