I hope you can help me.

Here are the Windows 11 power settings on my HP ZBook Firefly 15 G7. The laptop lid is often down. I reset the defaults on my Samsung S20 D70XE.

I have tried many settings. But nothing seems to work.  I hate to waste so much power and burn my screen

    Hello,

    Every category says None, so no app or driver is holding the display or system awake. The problem isn’t a stray program; it may be a setting (or firmware) telling Windows what to do.

    Run this in the same admin prompt: powercfg /setacvalueindex SCHEME_CURRENT SUB_BUTTONS LIDACTION 0 and then powercfg /setdcvalueindex SCHEME_CURRENT SUB_BUTTONS LIDACTION 0, followed by powercfg /setactive SCHEME_CURRENT. That sets “Do nothing” on lid close for plugged in and battery, and it applies to the plan that’s actually active, which is often where people get tripped up when they’ve been editing a different plan.

    Please note that this is a public forum. I will do my best to respond within a short time, and I apologize for any delay. I’m simply another user sharing insights and information that may be helpful to others.

    Hello again.

    Please try these steps: open Command Prompt as administrator and run powercfg /requests.

    It lists whatever is telling Windows to keep the display or system awake, and it’s often a browser tab playing video, a remote desktop or Teams session, or a driver.

    If something shows up under DISPLAY or SYSTEM, close that app and see if the screen finally turns off.

    Hi, let me help you.

    Do you have any third-party devices connected? If you do, remove them and then check if the machine goes to sleep.

    Is your Windows up to date? If not, please update Windows.

    Try this Windows 11 check list in order:

    1. Set lid close to Sleep
      • Open Search on the taskbar, type control panel, and open it.
      • Go to System and Security > Power Options > Choose what the power buttons do.
      • Select Change settings that are currently unavailable.
      • For When I close the lid, set On battery to Sleep.
      • Set Plugged in to Sleep too if the lid is often closed while connected to power.
      • Select Save changes.
    2. Shorten the screen and sleep timers in Settings
      • Go to Start > Settings > System > Power & battery > Screen and sleep.
      • Set On battery power, turn off my screen after to a shorter time.
      • Set On battery power, put my device to sleep after to a shorter time.
      • If the laptop is usually plugged in, also reduce the Plugged in times.
    3. Use a more efficient power mode
      • Go to Start > Settings > System > Power & battery.
      • Under Power mode, choose a more efficient mode, or Best Power Efficiency if available.
      • This can reduce background activity and power use.
    4. Turn on Energy saver
      • Go to Settings > System > Power & battery > Energy saver.
      • Turn on Lower screen brightness when using energy saver.
    5. Check display settings that affect power use
      • Go to Start > Settings > System > Display > Brightness and lower brightness.
      • Go to System > Display > Advanced display and select a lower refresh rate.
      • If available, enable Dynamic refresh rate.
    6. Run the Power troubleshooter
      • Go to Start > Settings > System > Troubleshoot > Other troubleshooters.
      • Select Run next to Power.
    7. If the PC still refuses to sleep, use a temporary workaround
      • Install PowerToys from the Microsoft Store and use Awake to control sleep behavior while troubleshooting.

    Since the lid is often down, step 1 is the most important. If When I close the lid is set to Do nothing, the laptop can stay awake with the screen behavior controlled separately, which matches the problem described.
