I don't know the best way to describe such weird issues but sometimes when I startup my laptop these won't work.
the only way to log into windows is by attaching an external keyboard or using the on-screen keyboard.
in device manager, disabling and re-enabling the keyboard wont fix it
the only way I found to make it work is by executing lenovo diagnostic utility, and despite it wont find/correct any issues it will somehow solve the problem (temporary)
wont work on some apps like skype: "no device found" or windows camera: "0xA00F429F<WindowsShowFailed> (0x800706D9)"
but works flawlessly in google hangouts.
lenovo utility reports all drivers are updated
tried already uninstall/reinstall related drivers
