Laptop screen keeps dimming (IdeaPad 310)

2018-01-19, 20:19 PM

I have an IdeaPad 310.

The screen keeps dimming on its own, sometimes every few seconds, sometimes after a good while.

When I click F11 or F12 the screen quickly shows what the brightness should be before brightening (F12) or dimming (F11) as if the first dimming didn't happen.

I went to the power options --> enable adaptive brightness but both of them are off.

Thanks in advance.

There are hundreds of suggestions about how to fix this.   Different things work for different people because the computers and the software differ so one solution will work for one person but not another.   Our symptoms were that on battery power after a number of seconds (did not time it but it was probably 10 or 15 seconds) our display would dim if we were not actively typing on the keyboard.   We have a Lenovo X1 Nano with Windows 10 Professional.

We tried a LOT of things that did not work.   Like turning the Intel Graphics Command Center Power Saving Option to off.   Also hacked the registry to re-enable the Auto Dimming setting in the Advanced Windows Power option so we could turn it off (set it to 0).   Also noticed the Night Light was already off so that was no help.   Did a registry hack to permanently disable the Adaptive Brightness settings.   

We tried a LOT of other things and NOTHING worked for us.

 

We finally did find something that seems to work.    It may not work for you, but I am posting it because it might work for some people since it worked for us.

 

We went to Device Manager -> Batteries -> Microsoft ACPI-Compliant Control Method Battery and right clicked on it.   Then we selected 'Disable Device'.

 

So far nothing else has been affected.   Interestingly enough, the Intel Graphics Command Center Power controls disappeared from that application interface.

 

It has stopped the auto-dimming where nothing else we tried has succeeded.

Hi Gaius Gracchus,

 

Thank you for openly sharing these steps to the thread and to the community. This would surely be a reference in the future for other folks going through a similar issue.
