Hang: Left alone too long
Had to reboot (as always, using a long-press on the power button) after I left the Dell alone for 20 min to make a call. Outlook, firefox were up, but the Dell had gone to standby while connected to power. No idea what caused it, but returning from standby hung before i had the keyboard up.
This might be related to my habit of hitting caps-lock to watch for a flickering light to tell me when the Dell has come back (Mac takes 2-3 seconds after opening the cover before it’s usable, from full sleep, so even 10 seconds seems like 3x too long).
All work lost, but at least it was near the start of the day.
