any idea? I tried also to click with a pin the 'upside down U hole' near the microphone, it only booted to bios.
i tried to update and reset bios, to set keyboard drivers as lenovo standard keyboard and standard keyboard instead of elan but nothing. when keyboard and mouse doesn't work keyboard backlight is off (for mouse i mean touchpad, and gestures don't work too). when keyboard doesn't work but mouse yes, keyboard backlight is on. keyboard and mouse work only for 5 minutes after windows installation, than first the keyboard and than the mouse stop working. I updated every driver with snappy driver installer, reinstalled windows and installed driver with driver booster, reinstalled windows and installed drivers from lenovo official support page, but nothing.
Hello, I just got a lenovo yoga 720 15lkb ideapad, it was all good but keybooard and mouse stopped working, also keyboard backlight was off.
