I noticed that, from time to time, more or less randomly, my Aerobook screen flickers for a fraction of a second. It does it randomly, perhaps twice in an hour, then no flicker for the next hour, then again, and so on.
The only pattern I have observed is that it appears to flicker only when the laptop is operating on AC power and/or charging. I haven’t observed the flickering when the laptop is operating on its battery.
Any hint what could this be?
