T25 Auto Brightness Issue - Persistent!

2018-07-10, 15:33 PM

Hello everyone,

I own a beautiful ThinkPad T25 Anniversary Edition and since day 1 the auto dimming brightness feature has been driving me absolutely nuts. No matter what settings I turn off the screen STILL dims when it's on a black or dark image (like my default T25 desktop or dark websites).

- I have disabled the Windows auto brightness feature.
- I have disabled the Intel Graphics Power Savings Mode feature on ALL power plans.
- I have updated my drivers and ran all available updates through Lenovo Vantage.

I really don't know what else to do. I don't really use this laptop much, otherwise I would have complained about it a lot earlier, but I am recently traveling and the T25 is my only machine right now and this auto-dimming on dark screens is driving me to insanity! I write code on my machine and switching between dark and bright screens is a very common thing! Please help!

Thank you.

Intel HD Graphics Control Panel --> Power --> Display Power Saving Technology

Is this what you disabled?

Yes it is exactly what I disabled. Sometimes ir works but sometimes it doesn't have any effect, and the screen continues to dim automatically! Sometimes unplugging the power cable and re-plugging it back fixes the issue but not always. Sometimes a reboot will fix it, It's extremely annoying! I cannot for the life of me disable this auto dim feature permanently!
