[Bug 1396857] [NEW] [Lenovo T440s] Power button can't bring up the Shut Down menu

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

CID: 201308-14073 Lenovo Ts440s

On 14.04.1 (3.13.0-40)
When you press the power button, it won't open the Shut Down menu like other laptops.
It seems that the power button on this system is not sending any keycode to the system.
Nothing can be captured by "sudo showkey -k", "sudo showkey -s" and "xev"
