  1. Surface wakes up from standby always with maximum brightness


    Surface Pro 6

    Adaptive brightness doesn't make a difference.

    The brightness setting shows me my last brightness but the brightness itself is 100%.

    As soon as i click at the brightness setting bar it sets the correct brightness.
    Restart didn't work.


    Seems like the hardware can't get the last brightness setting at wake up.

    :)

    Surface Pro 6 goes Standby every 30min-ish (SC_MONITORPOWER)

    I see you have set the Sleep setting to never. As a further step, on the same window, in the same list, there should be an option for the video card as well. Just to be sure, set that one to maximum performance. Another thing I can think of, is if there is any surface specific battery saver software, one that would come pre-installed, which overwrites the settings you already changed. Might be good idea to check that too.

    Actually, I have looked more into it. It seems very likely that your problem comes from the Windows "Connected standby" feature. For some reason many surface devices have problem because of this feature. What you can try is to disable this feature. For many it seems that it fixed their strange behaviors on the surface. Here is a link to toolofgod it explains in detail how this feature can be disabled.

    The instruction for disabling it:
    "Open regedit then navigate to
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\CsEnabled

    If you have Connected Standby enabled, this variable will have a 1 (one) in it. To disable it, double-click on the CsEnabled variable and put a 0 (zero) in there. Reboot and you are done."
