You may notice that when you unplug your laptop from power connection, the screen dims automatically and you have to manually adjust the brightness of the screen. This can be very annoying if you plug/unplug your device frequently. You can disable this feature on your computer very easily.
Fix-1 Disable battery from Device Manager-
Disabling battery devices on your computer will solve this issue.
NOTE–
Disabling the battery devices on your system will remove the battery icon (showing charge percentage) from the Taskbar and will disable other power options.
1. Press Windows key+X and then click on “Device Manager“.
Device Manager window will be opened.
2. In the Device Manager window, click on “Batteries” to expand it.
3. Then, right-click on the second battery device “Microsoft ACPI-Compliant”
4. Finally, click on the “Disable device” to disable the battery.
This way disable all the battery devices under ‘Battery‘.
Note: – If it does not work, enable it and try disabling the other one in the list.
Now you will see there is no battery icon on the Taskbar and all the power options disabled.
The laptop screen won’t be dimming further upon unplugging it from power.
Your problem should be solved.
NOTE–
If you want to re-enable the battery devices on your computer, follow these steps-
1. To open the Device Manager window, press Windows key+X and then click on “Device Manager“.
2. In the Device Manager window, again expand “Batteries“.
3. Now, right-click on the disabled device and then click on “Enable device” to enable it on your computer.
Following this process (step-3) you can enable the battery devices again on your computer.
Method-2 Change Display Power Saving Technology-
Changing the power saving technology settings will stop this problem.
1. Press Windows key+R to launch Run window on your computer.
2. Now, type “Control Panel” and then hit Enter to open Control Panel window.
3. In the Control Panel window, on the top-right corner, click on the search box and then type “intel“.
4. Now, click on “Intel HD Graphics” which will appear in the search results.
5. In the Intel HD Graphics Control Panel window, click on “Power” settings to modify it.
6. In the Power settings window, on the left-hand side of the window, click on “On Battery“.
7. Now, under ‘Display Power Saving Technology‘ the settings, click on “Disable” to disable it.
8. Finally, at the rightmost corner click on “Apply” to apply the settings on your computer.
Close Intel HD Graphics Control Panel window.
Thank you sir. It worked. I was fighting with it for days.
These steps worked for me to prevent from dimming the display when charger unplugged.
Open Control Panel > Type Intel in search and click Intel HD Graphics > click Power > click On Battery > change Change Display power saving technology to disable and click Apply at bottom. Done.
Thank you so much 🙂
Worked for me. Right-click on desktop -> AMD Radeon Software -> Settings -> Display -> Disable the Vari-Bright Level. Thanks for the help guys
I tried all that steps, but not work for me, so, after read comments from Chingis J. i adapted this steps to solve the problem.
– Right-click on desktop -> AMD Radeon Software -> Settings -> Display -> Disable Virtual Super Resolution.
YES,IT WORKED.
THANKS.
To prevent dimming when plugged off:
– Right-click on desktop -> AMD Radeon Software -> Settings -> Display -> Lower the Vari-Bright Level
After way too much messing around trying to find the answer, this worked great! Thank you
Awesome fix (#1), thank you!
bang on man, second one works for me
Thank you! It worked for me.
Your 1st Solution only works with Intel based CPUs. What about AMD based PCs?
Your 2nd Solution only causes new issues. What good is that?
Seriously, I’m not trying to Nit-Pick, but this Half-Baked-Potato quality information.
Fix 2 worked for me. Well done mate. Good finding 🙂
thanks so much for this! very helpful!
it worked like a blessing for me thanks for it btw second option worked for me….
thumbs up for ur suggestion
The first method worked for me. Thank you so much. my dimmer screen was driving me crazy and changing power options/plan was not working. This did!
Worked for me. Now how will I know if my laptop needs to charger? Doing the above got rid of the battery life display.
Worked like magic. Thanks.
It still dims, i’ve adjusted all my windows power settings, my intel power settings and now this and it STILL dims so much i can’t read the screen without a flashlight (my laptop is an asus x555la and doesn’t have adaptive brightness). Do you have any other suggestions?
