YOGA500 after sleep function keys not working

2016-02-25, 20:30 PM

Hallo,

i have problem with my YOGA500-14IBD Windows 10. Into January everything worked. From January not working function keys after sleep mode. When I turn on the notebook, everything works. But after returning from sleep mode, some of the function keys do not work. F5 (refresh the page), F6 (touchpad on/off) and F10 (second screen mode). I re-install windows and installed all drivers, but no change.

After restarting, everything works into sleep mode. After waking up not working.

 

Does anyone have any idea?

 

Thank you very much.

Hi,

problem solved.

 

I reinstalled windows on deposit W8.1 from the backup. Keys did not work.

Finally, I flash the BIOS from 63 to 63. Reflash same version... Function keys work!

I installed W10 and everything works.

 

Thank you all.

Hello,

 

In the Device Manager, Keyboard section, double click on the keyboard listed, Driver tab, Details.

You should see 3 files:

- i8042prt.sys

- kbdclass.sys

- a third one: maybe SynTP.sys, or ETDSMBus.sys, or APKbFiltrdr.sys (depending on the keyboard model) ?

 

Which file is the third one, and what is its version ?

 

Also, you should update the Yoga to the latest BIOS version, if it's not already done:

Hello,

 

I see you have the 1.0.0.2 version of Apkbfiltr.sys of the Alps touchpad driver.

Maybe you could try the 1.0.0.1 official version of Lenovo here:

I doubt it will change anything, but I don't see much else to try.
