I had this Lenovo Flex 3 1580 worked fine. Suddenly it won't power up. After open it up, I found it can start with lid closed when I plug in the power adapter. (No need to press the power button) If the lid is open, it won't start after plug in the power. After it is powered up, the on-screen keyboard works. But the mouse pad and physical keyboard won't work. The power button won't do anything.
From the symptoms, it looks the keyboard control is not working. The logic of the signal from the lid sensor is reversed. If just one thing is broke, what is it?
