Windows 10: Laptop display brightness stuck in Balanced Power Mode

Hi all,

Have a strange issue. As the title suggests, I can't change my laptop's display brightness when 'balanced' power mode is selected. Doesn't matter if I use my fn keys or the native windows slider. Changing the mode to 'high performance' unlocks the brightness slider again.

What's going on here? All plans are restored to default. Windows has latest updates and my display drivers are also up to date via intel driver assistant as well as my manufacturer's native driver utility.

Thanks in advance.



Edit: I am connected via HDMI to an old external display whose own menu/brightness adjustment buttons have stopped working.

1. If I UNPLUG the display and restart, I am temporarily able to change display brightness in 'balanced' mode again, but sooner or later the problem will reappear while in usage.
2. If I keep the display PLUGGED IN and restart, the problem persists at startup.
3. If I UNPLUG the display WITHOUT restarting, the problem persists.

Could it be a hardware thing?? I've never heard of such an issue.

Power Plan stuck in Balanced Mode.

I have this bug for some time now but since i couldn't find a fix for it i decided to post it here to see if anybody could help me.

Basically, my power plan is stuck on Balanced mode and whenever i try to choose the Maximum Performance mode it just resets to Balanced Mode again.

I have tried to create my own power plan but with no avail, it still reverts to balanced mode. Does anyone know the fix for this?

Thank you guys in advance and sorry for any spelling/grammar mistakes, English is not my native language.

 

DPC Issue In Balanced Power Mode

Hi Corey,

Thank you for writing to Microsoft Community Forums.

What is the issue that you are facing with the sound?

The difference between Balanced Mode and Power Saver Mode is that Balanced Mode automatically increases the CPU's speed when the computer needs it and reduces it when it is not necessary. The Power Saver Mode will attempt to save power by reducing CPU's
speed all the time and lowering the screen brightness with the intention of increasing battery life.

Also, we have another mode, i.e., High Performance Mode and this mode does not lower the CPU's speed when it is being used and also increases the screen brightness.

For the DPC issue, put your computer in Balanced Mode, follow the below methods, and check if this helps.

Method 1: Disable Dynamic Ticking.

Step 1: Click on the Start Menu and search for
Command Prompt > Right-click on Command Prompt > Click on
Run As Administrator.

Step 2: In the Command Prompt window, type the following command and hit
Enter.

bcdedit /set disabledynamictick yes

Step 3: Once the command is executed successfully, you should see
Operation completed successfully message, so exit from Command Prompt and check for the issue.

Method 2: Update Graphics Card.

I suggest you to follow the steps mentioned in Update drivers in Windows 10 and update your Display
adapters drivers and check for the issue.

Method 3: Tampering with Network Devices.

Step 1: Click on the Start Menu and search for
Device Manager and hit Enter.

Step 2: Expand Network adapters and locate the Wireless and Ethernet adapters (they should be at the top of the list and carry a bran's name such as Intel) >
Right-click on each one and click on Properties > Go to
Advanced tab > Locate Energy Ethernet and disable it by choosing the option under
Value and choosing Off.

Step 3: Then, go to Power Management tab and
uncheck the box next to Allow the computer to turn off this device to save power (make sure you repeat the process for all suitable devices that you apply the changes and check for the DPC issue).

Method 4: Disable Firewall/Antivirus.

If you have installed any third-party security software, I suggest you to temporarily disable them and check for the DPC issue.

Note: Software helps protecting your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software and\or troubleshoot any
pertinent issue, you should re-enable it as soon as you're done. If you are connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to malware attacks.

Method 5: Finding The Device That Is Causing The DPC Issue.

The common problematic devices that may cause the DPC issue are Network/WiFi adapters, card readers, sound devices that are not in use, Bluetooth adapters, and graphics card.

To narrow down which device is causing the issue, try disabling the above device one by one from Device Manager and then run the DPC test again. If DPC test is successful, then enable each device and run the test again to see exactly
which device is causing the issue. If you find the device that is causing the issue, then uninstall that device from your computer, go to the manufactures website, and install the latest drivers for that device, else get back to us to help you further.

Give it a shot and let us know of any changes.

Hope it helps.
