I have a Yoga 14 20FY0002US running Win 10 Home. BIOS 1.49.
Once in a while, the laptop will freeze if it is running on AC power. If I disconnect and reconnect the AC power, the laptop becomes responsive. I haven't detected a pattern.
Naturally, if I'm at the computer, it isn't a big deal. But I use it to control a lab instrument and it needs to run experiments for hours at a time. Right now, my only "fix" is to use battery power (it hasn't frozen yet).
Any solutions for this?
I am VERY reluctant to update my BIOS (from 1.49 to 1.57). The last time I tried that, it bricked the laptop and had to go back for factory repair.
