Recently updated to windows 11, worked fine and updated all drivers and software after the OS update. Then just stopped responding after I switched it off. It automatically switches on the screen back light, and does not respond to the power button besides when I press and hold it for 5 seconds, it switches off and when I let go, the back light comes on again
