trouble waking up from sleep
My fairly new MacBook Pro (Catalina) has difficulty waking up from sleep. It will flash the screen (and the monitor I have attached as well), sometimes for as long as 90 seconds! Once fully awake, it behaves fine. It behaves a little better if I actually put it to sleep, rather than let it time out, but some times it flashes even then. Even stranger, it will wake up in the middle of the night! Any ideas?
