Screen brightness not adjusting

Hi!

 

My Lenovo Yoga 710 14-IKB is now stuck on medium brightness and I can´t change it. I have tried to disable and enable generic PhP drivers and rebooting. Brightness adjusting was working fine 3 hours ago but now when I booted up my laptop, it wasn´t working.

Re: Screen brightness not adjusting

I fixed it! I had an BIOS update on Lenovo Companion and updated it and I can now adjust the brightness again.

Re: Screen brightness not adjusting

I encountered the same problem, I called the support and they asked me to press for 20 seconds on the computer power button, the computer restarted and everything worked out.

Re: Screen brightness not adjusting

An improper shutdown by holding in the power button until the computer kicks off has been reported to work. However, instead of an improper shutdown, do a FULL SHUTDOWN. Open a CMD window, type "shutdown /p" no quotes and press enter. Let it shut down properly then restart normally. Don;t know how to open a Command (CMD) window? In the Cortana window type cmd - then choose the black thing at the top. This full shutdown trick also works to reset Windows Update should it ever gets stuck.
