How to turn off the Surface keyboard backlight

When it comes to saving battery, one of the things that you can do that is effective is to turn off the keyboard backlight of your Surface device. Note that other mobile devices will benefit from this as well, but that they may or may not support functionality to turn off the lighting of the keyboard.

The Surface Pro ships with a sensor built-in that will activate the light on the keyboard to highlight the keys better. This is a useful feature as it helps you identify the keys on the keyboard which may be an issue in low-light environments.

This is not much of an issue if the Surface device is connected to a power outlet, but if it runs on battery, you will notice that the lighting makes the battery drain faster.

The guys over on Linus Tech Tips ran battery saving tests recently which concluded that turning off the keyboard backlight extends battery use before you need to recharge by about 16%.

Other beneficial battery saving tweaks included:

  • Removing mouse and keyboard peripherals (20%-30% longer battery life on a single charge)
  • Turning down the brightness of the display to 50% (16% longer battery life, turning it further own is less efficient).

Turn off the Surface Keyboard backlight

The Surface keyboard backlight turns on and off automatically using the built-in sensor. You have controls however to toggle the backlight manually as well, but it may not be available on older versions of the Surface keyboard.

The first two keys next to the Esc-key on the keyboard above, those with the function keys F1 and F2, control the keyboard backlight on the Surface device. If you just tap on the keys however, you will notice that nothing happens. Or, to be more precise, that you press F1 or F2, and don't toggle the keyboard lighting functionality.

You need to hold down on the Alt-key to access the special keys of the Surface keyboard. So, this is how you turn the backlight of the keyboard on or off:

  • Increase the keyboard backlight on with Alt-F2
  • Decrease the keyboard backlight off with Alt-F1

Activating the special keys increases or decreases the keyboard backlight on the Surface keyboard. You may need to activate the key multiple times to turn it off completely, to make it less bright, or brighter.

Verdict

If you need to squeeze the maximum battery duration out of your Surface device, you need to consider turning off the backlight keyboard of the Surface. While that may not be an option at all times, for instance in dark environments that make keys hard to identify, it is usually possible to at least turn the brightness of the lights down.

Now You: Do you have other power saving tips for mobile computers?

    Processor power management
    Minimum = 00
    Maximum = 50

    Note these values represent the percentage of your CPU’s multiplier. You can use something like CPU-z to see the values which your CPU supports, depending on the CPU you may want to choose something between 30 and 50. The idea is to not let the CPU raise it’s multiplier high enough to need the increased power needs for said higher values.

    Search for a program called nvidiaInspector (doeanload it from Softpedia or Guru3D). The author is Orbmu2k.
    You can do a few things with it to make Nvidia GPU’s consume significantly less power than usual. First, right click on “Show overclocking” button and you have a power saving option.
    Second you can run the program with this argument:
    nvidiaInspector.exe” -forcePState:0,12
    to force the GOU in its lowest power state. Use:
    nvidiaInspector.exe” -forcePState:0,16
    to revert back. (or restart, this setting doesn’t stick)

    Disable Intel’s integrated GPU, it’s useless and you can make Nvida GPU consume a lot less power. Alternately you can go further and enforce a 30fps global limit (also in NvidiaInspector, click on the key/screwdriver button).

    Note: NvidiaIsnpector is portable. Version 1.9.7.3 requires NET 3.5 (enabled on Win7 by default). Newer versions require a combination of 3.5 and 4.

    You can do a few software-wise things as well:
    – disable smooth scroll in browser
    – disable transparency in Windows 7 (do not dsable Aero completely)
    – mute speakers/microphone, or bring them to 0 (this cuts off the power)
    – the more animations you can do with disabled the better (disable showing of windows contents while dragging if you plan to move around your windows a lot)
    – unless your outside brightness to lowest possible should be just fine
    – the less programs open you have the better (including useless placebo-tier ones like antivirus programs)
    – set screen timeout to a lower value like two or three minutes
    – go to Device Manager and check whether or not your wireless card’s power saving features are enabled/auto

    [1] and [2] will bring the largest gains as it will also eliminate that fluctuation of “time remaining” as you use your laptop. Power consumption should be minimal regardess of what you do (even watching a 720p movie).

    Speaking of movie, use a player that supports Cuda decoding (like MPC-HC, look in settings, needs to be configure to use it). It is the most power efficient one. Nvidia-only.
