How do i fix my system wouold not sleep and screen

Baha Habashy 80

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

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.

Thank you for your help. By third party, does this include a mouse, keyboard, external SSD drive or HDMI monitor? If yes, I do and can not do without them. I have a similar setup on another PC, but it works fine. Do I have a solution for this one?

Try this Windows 11 check list in order:

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.

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.

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.

Turn on Energy saver

Go to Settings > System > Power & battery > Energy saver.

Turn on Lower screen brightness when using energy saver.

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.

Run the Power troubleshooter

Go to Start > Settings > System > Troubleshoot > Other troubleshooters.

Select Run next to Power.

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.
