    Screen not turning off


    Hi guys!I have a Toshiba Encore tablet with windows 8.1 on it. After an update yesterday, the screen doesn't turn off when it gets in sleep mode.It turn black, but it still has the background light on.The same update messed up the screen luminosity.It is set to maximum by default, and no matter how much I change it, nothing happens.The battery drains very fast with the screen on this way and I really don't know how to solve it.I tried system restore, but it didn't have any images saved, so I need a solution apart from that.Many thanks!

    You could try rolling back the updates until you uninstall the "bad" one. Process of elimination is all I know if you cannot restore point your way out or apply a backup image.

    I've done that few minutes ago, but it still doesn't want to turn off the screen

    I would try the Toshiba Forum. If an update is causing it then a lot of people would likely be looking there for an answer.

    Also someone may chime in here that has a work-around.
    Myself I turn auto updates off because it's too many changes to track. When something goes weird it takes too much time to track it down. If it is something that fixes a problem I notice on my system then I'll install it manually.
