    Screen Blank after one minute but I set it to 20


    This happens on Lenovo Thinkpad W550s with Win10 Pro. I do not have Lenovo crapware on it, because I did a clean, generic install about 1.5 year ago. I have never had this problem on a Windows desktop with Win10Pro or a Dell laptop with Win10 Pro.
    Behavior
    After one minute of inactivity the screen goes blank. Shake the mouse and I get the lockscreen. Have to enter code to unlock.
    Settings
    I have set screensaver to None and screen timeout to 20 minutes when plugged in, 10 minutes on battery. So why does it blank after one minute?
    Solutions?
    I have tried many solutions. Sometimes it works as set for a few weeks, then reverts to one minute. Sometimes the screen goes blank after 20 minutes, but it never goes to lock screen!
    No matter what I do it always reverts in a few weeks to this one-minute blank and lock behavior.
    Currently I have set a reg key: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\InactivityTimeoutSecs. Oh, I've set it to 7200 (2 hours). BTW, I didn't set it by using regedit, I set it by using secpol.msc.

    It's so exasperating. I see that many people have this problem. Where is Microsoft in all this?

    :)

    Screen goes blank after changing BIOS settings/

    I don't know how long this has been happening, a few weeks at least, but whenever I change a setting in my BIOS (and save & exit), my screen goes blank and my monitor goes into standby. Any suggestions to fix this?

    Hi Virginia,

    Conflicts with third-party software and outdated graphic drivers are common contributors to the black screen issue that you're having. To isolate the said issue, we'd like to ask a few questions:

    • Are you getting any error messages before getting a blank screen?
    • Are you experiencing this when using a particular app?
    • Were there any changes made on your computer settings prior to this issue?

    Meanwhile, we suggest that you refer to this
    article
    which talks about the steps you can take to resolve blank screen errors.

    We'll wait for your response and assist you accordingly.
