Windows 10: Screen dim after waking from sleep

    Screen dim after waking from sleep


    Recently I have been finding that when I wake my laptop from sleep, the screen is set to minimum brightness, even though it was at maximum brightness when I put it to sleep. I've only been having this problem recently before that I was using Windows 10 without running into this problem. It's an annoyance rather than a catastrophic malfunction, but it is starting to annoy me quite a lot. How can I get the machine to wake with the same brightness as when I put it to sleep?

    I've got a Lenovo Yoga 710 with Intel Graphics (plus NVidia graphics as well).

    Hi ricecrispies

    As this just started lately what has changed?

    Did V1803 get installed on your device? or was a video driver updated ?

    Recognize this is not your model but people having brightness issues on Lenovo's after 1803

    It looks like I'm still on 1709. I'm not sure what changed. But it's changed again since I posted. When I posted, the login screen was dim and it stayed dim once I'd logged in. Now it brightens back up when I log in, which makes it a bit less annoying.

    Please have a look at your windows update history. Towards the bottom the drivers are listed. Did a driver get updated around the time you noticed this issue?

    Uninstall the Display Driver, reboot and let Windows reinstall. Known issue.

    It's due to a Lenovo setting.

    Open Lenovo Vantage, navigate to Hardware Settings > Audio/Visual, then turn off Dynamic Brightness Control.

    Perhaps - seems to be a Lenovo thing anyway - there is lots on reddit regarding 1803 and Lenovo.

    It happened to me yesterday (Lenovo X201) but I don't have any Lenovo software installed - just a clean install of 1803 - and usual fixes (close/open lid, adaptive brightness) didn't work. I've clean installed every version of 8 and 10 on this laptop and it is the first time it happened to me although from my limited research the issue seems to date back to Windows 7 at least.

    A simple reboot (without doing anything else) fixed it for me and I've not been able to make it go wrong again.

    Some say setting sleep (Alt+F4) and then shutting lid before sleep state is completed will reproduce this error but so far I can't. It may be worth changing what closing the lid does to "nothing" and playing around.

    I found it quite alarming initially tbh - I thought the screen backlight had broken or something (this laptop is 8 years old so quite likely to start falling apart).

    It is actually due to a known issue with the latest driver updates for Windows 10. Dynamic relies on a sensor to adjust. The issue is not the sensor.
