Windows 10: Screen takes long to turn on and can't change brightness after automatic display turn off...

After i update my laptop to windows 11, a lot of bugs occured but most of it got fixed along with the newer updates, but one problem still remains and it's really annoying.Windows power plan have the option to turn off display automatically after some time, and also the option to sleep automatically. After this update, everytime i try to turn my display back on after either option are carried out, it usually tkaes around 30 seconds to 2 minutes for the display to turn back on, I can confirm that it is only the display that takes long to boot up because i can type my pin to get into the desktop

screen brightness on windows 10

Hi,

Some computers can let Windows automatically adjust screen brightness based on the current lighting conditions.

To manually adjust the screen brightness, we suggest following these troubleshooting steps:

• Click Start, then select Settings.
• Choose System, then select Display.
• Under Brightness and color, move the Change brightness slider to adjust the brightness.

Feel free to post back if you have other concern.

 

I can't turn off Change brightness automatically...

Hi Nguyen

Are these the steps you are using:

Open the old Control panel

Choose Power options

Click 'Change plan settings' next to the current power plan.

Choose 'Change advanced power settings”'

Scroll down to locate the 'Display' and expand it for 'Enable adaptive brightness' and turn that off from there?

 

Screen brightness change automatically

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that the screen brightness change automatically while watching videos.

• Are you aware of any changes made to the PC recently?
  
• What is the model number of Lenovo Yoga PC?
  

Windows 10 has the ability to automatically adjust the screen brightness depending on the ambient light levels. This feature can be more annoying than helpful, either leaving your screen too dark or frequently
adjusting the brightness levels.

If you are using Lenovo YOGA 3 Pro-1370, I suggest you
Disable auto brightness feature
and check if it helps.
