    Power settings resetting and disabling passwords


    Greetings folks,

    I'm having two problems with my new Dell XPS 8930, and I suspect they're related.First, the power settings keep reverting to "Power saver." I repeatedly set it on "High Performance," but it frequently switches back for no clear reason. This often happens in the middle of the night, when no user applications are running.

    Attempts:
    * Monitored CPU / GPU idle temperatures to see if they're running hot. Ruled out due to reasonable temps (41C / 55C).
    * Created my own custom plan (matching the "High performance" plan). No effect
    * Looked into a way to make the power plan registry settings read-only. Aborted effort before I broke anything

    Normally, I wouldn't care too much about the "Power Saver" setting, except that the setting allows the system to go to sleep, which prohibits me from remotely accessing the desktop from TeamViewer. My goal in this case is to ensure that my system never, ever goes to sleep under any circumstances, so I can remote-access it at any time.=================In addition, some mornings when I bring the desktop out of sleep mode, it demands a password.

    Attempts:
    * A month ago, I followed the instructions here to disable the password screen.

    Still, when the computer comes out of sleep (which it shouldn't be doing anyway), the password is demanded. I reviewed the checkbox (see link in previous paragraph), and it remains unchecked. Regardless, I'm forced to enter the password when the system comes out of sleep mode.

    My goal is to disable the password requirement completely.Many thanks for any help.

    Ok... I think I found my own solution, though it's a rather brutalist approach.

    This page describes how to export power plans to files, which should be done via command prompt elevated with administrator privileges. The command is powercfg - and there are several flags of note.

    Use /L to list all of the plans. Note that a GUID is listed for each one.

    Use -export (in conjunction with the GUID) to export each of the plans except for the one that you want to use. Put these files somewhere safe, ideally with the instructions.

    Having exported the power plans and backed up the files safely, use -delete (in conjunction with the GUID) to delete each of the undesirable power plans.

    When you're done, the only power plan remaining will be the one you want, and neither Windows 10 (nor any application) will be able to surreptitiously switch you to another power plan.

    Based on a single overnight test, there are no side effects. I'll post if I learn otherwise, but I rest easy knowing that I have all of the deleted power plans backed up. Furthermore, even without the backups, I believe I can restore them with the powercfg -restoredefaultschemes command.
