My Lenovo Yoga 500's keyboard and the trackpad isn't working. I already tried disabling ymc service but it didn't help. The only keys that are working are F9 to F12 but the rest are not working even the Caps lock key wouldn't show the light. The keyboard and trackpad also doesn't work in then login screen. When I connect another keyboard, it works perfectly fine. Ths happened after I put my laptop to sleep for the first time. Please help :(

Hi there!

Some people had that problem too when their yoga went to sleep or hibernated. I read some solutions that BIOS update might work!

Hi

I also have a Lenovo Yoga 500 running Windows 10 and have had the same problem as many others with the keyboard and touchpad suddenly stop working. I have done a system reset, updated the BIOS and even run a Lenovo system update, all only giving a temporary fix. In the last few days I have narrowed it down to a 'glitch' in the screen rotation changes, even though tent or tablet mode are hardly ever used. This is what I have found and currently have to do on each start up.

Power up the machine in laptop mode, flip over to tent mode and let the screen rotate and settle for a few seconds. Flip back over to desktop mode, watch the screen rotate back and hey presto the touchpad, mouse and keyboard are working again! Sometimes only angling the the screen forward a few degrees will do it, without going to tent mode first.

This is what is currently working for me, hope this is of some help :)
