I have a Yoga 720-13IKB (base model from 2017), and I cracked the touchscreen a few months ago, and replaced it a day or so ago. I noticed that when I either unplug the AC power, or replug it back in, the screen flashes black for a second or two, then comes back on. it does not affect the functionality in any way shape or form, it is just really really annoying. I have found people who have the screen turn totally off when unplugged, but it does not do that for me, it just flashes black for a second. Any ideas?

Hello and welcome,
It may be that your power plan settings have different refresh rates set for battery and AC power. When the refresh rate changes the screen blanks briefly while adjusting.
I'm not sure where or if that setting exists on your particular machine. Sorry I can't be more specific.
