Michael von Glasow:
1) To clarify, did this issue start to happen after an update? If so,
2) Does this issue happen if you don't have any external displays, and
the laptop is not docked?
3) Regarding the internal laptop display going black for a few seconds,
how often does this occur per hour, day, etc.?
