I have been having a problem with the "on-off" key on my 14z 5423 laptop. If I hole the laptop and rotate it toward me so that the screen is parallel to the desk, and press the on-key, it turns on.
Second, and more annoying: the hotkeys. One (the MAXX sound hotkey, the one in the center) is on and I can't turn it off. Is it a reasonable solution to take the keyboard off and unhook the connector for the hotkeys? And leave it disconnected?
