When I move my active pen over the area at the top of the keyboard, my XPS15 9575 turns off without me touching it. You can see it on this video:
In addition, the top button of the PN557W pen works very rarely - most of the time when I click it, double click it, or long press it, it doesn't do anything to my laptop. They are connected by bluetooth and I've got the latest drivers for the pen and the Active Pen program installed.
Sometimes while I'm using the pen it stops working and the mouse icon disappears when I'm hovering over the screen and pressing anything on the screen does nothing.
Are these issues due to software or my error or is the pen's hardware not functioning?
I have never seen or heard any pen having the ability to turn a Laptop off.
What are you current Dell Power Manager settings?
Boot into the BIOS (F2 on boot). Move the pen like in the video. Does the Laptop turn off?
Boot into SafeMode. Move the pen like in the video. Does the Laptop turn off?
