Hello,

I have a strange case for you: since one week my XPS 9570 won't switch on *when the cord is plugged in*. No lights, no beeps.

I CAN switch it on without the cord (on battery).

However, once booted, the power button does not switch it off (even if I keep it pressed 1 minute).

The battery is new, I changed it recently (4 month ago).

What I tried:

- to rule out a problem with the charger, I tried with a new DELL charger. It won't boot.

- to rule out a problem with the battery, I tried to boot without battery. I removed the battery, plugged the cord: It won't boot.

- Once on, the power button events does not arrive to the system. When I press it, usually a menu appears under Linux. But now, nothing. I verified in the system logs that the power button event does not arrive at all in the ACPI daemon when I press the button.
