XPS 13 automatically power on

my xps 13 power on itself automatically, no matter it's plugin or unplugged, it has been nightmare for me for years, sometimes I shut down the computer put on the backpack and it's turned on and cause super hot, very dangerous especially when I am on the airplane, because of that, I have changed 2 new batteries, I did research found many others had the same issue and without any solution, but I still want to try, it's very annoying, I hate this computer every night boots itself,, every night.
