    High guys,

    So today my Macbook Air 2012 running High Sierra 10.13.5 has started to develop a very strange issue where if I do not constantly move the mouse cursor it will log out.

    Usually if pops up with this prompt:


    But often just goes straight to sleep. I also noticed a few times after i tried restarting the computer fully that even the loading to log on screen was interrupted by being put to sleep unless I kept moving the cursor.

    I checked I had deselected the Security and Privacy auto logout which I had so it's not that. This happens with wifi connected and not, and when fully charged on battery and plugged in.

    It is almost like the power button is being pressed sometimes bringing this dialogue up. However I can't find an APP that will allow me to monitor if this button is registering as pressed or not.

    Anyone have any suggestions?

    I would try resetting the SMC if you have not already done so. Refer to the following Apple KB article.
