Lenovo ThinkPad Yoga, 4 years old. Great little device but maddening problem.
It is a 2-in-1 and I 've disabled "tablet mode" etc.
I use it for ONE THING ONLY. To hook up to TV and watch videos. I boot up, and all is well. But 90% of the time when I open a video, as soon as I do, the cursor and keyboard freeze. I can still manipulate via the touchscreen.
Other times it's moving the mouse for the first time that freezes it. I have to shut down, restart then all is well. It's like it's PROGRAMMED to do this ONE every OTHER log in session, but no more than once. I've even watched a video, shut that one down, then opened a 2d and that's when it freezes. So no rhyme or reason. Freezes basically when it's given ANY input whatsoever, with the first 5 input events (mousepad touch, screen move, file opening, etc.) then once rebooted, it generally won't do it again during the NEW reboot.
RESTARTING DOES NOT SOLVE. IT STAYS FROZEN. I literally have to hold the power button until everything goes dead, then restart.
