Yoga 900 Hotkey issue

I have a problem with my Hotkey F11 and F12.

Somehow it isn't possible anymore to control the brightness of my display.

 

What I tried:

 

1. Disabled all automatic control brightness functions in the Lenovo settings -> no success

2. Changed brightness manually via the Lenovo settings page -> no success

3. Disabled the Hotkey Mode in BIOS -> no success

4. Updated BIOS -> no success

5. Updated Grafics driver from the Lenovo download page -> no success

 

Does somebody know what I can do as well?

 

Thanks in advance Smiley Happy

Re: Yoga 900 Hotkey issue

Welcome to the Forums Yogauser!

 

Does function key feature working on-screen keyboard?

 

I've seen a lot of success with people regaining features by updating their Power Management software. This may be worthwhile solution for you. Lenovo Energy Management Driver.

 

Let us know how you get on.

Re: Yoga 900 Hotkey issue

Hi Shahsi,

 

Thanks for trying to help me with my problem!

The on-screen keyboard doesn't show me the function-keys at all. The keyboard layout is German.

I already installed the energy management driver with no success unfortunately. 

All other Function Keys of the keyboard are working fine...

 

thanks and best regards,

Wolfgang

Re: Yoga 900 Hotkey issue

We are sorry to hear that your issue has not yet been fixed.

 

If you still get the same problem, consider reinstalling the display driver (Intel) from the D:\Drivers folder or from the yoga 900 drivers page and observe.

 

Let us know how you get on.

 

Regards,

Shashi

Re: Yoga 900 Hotkey issue

I deinstalled the graphics driver and tried to install the one from the yoga 900 drivers page, where you sent me the link. During the installion it says that the driver is not validated for this computer and that the setup will be aborted.

 

Via the program "Lenovo Companion" you also have the opportunity to change the brightness but here it also doesn't change anything Smiley Sad

Last resort would be backing up your files and doing a factory reset to isolate if it's an OS issue.

However I would suggest you to visit the nearest Lenovo authorised support for hardware assistance.

 

Let us know how you get on.

Hi Shashi,

 

A factory reset "fixed" the issue. 

Thanks for your help!!
