My wife didn't take the car yesterday. I assumed she had taken the "little car" because she needed to park somewhere tight. She normally charges at work but given the car was on the driveway I used the fob to open charge-port and plugged it in. When she got home last night she said she hadn't taken it because "when I got in it didn't work" ... ... like a muppet I then forgot to take a look. This morning she didn't take it and sent me a reminder "I couldn't unplug the charge cable" (I suspect she would normally do that from Screen rather than Fob; we don't have a button-on-charger-plug). So I have now taken a look Main screen was dead. I pressed brake and both scroll buttons and continued to depress all three until the screen started up fully. (I don't know if that "continue to press" is actually needed?) I then saw that the car had not charged overnight ... and after reboot it immediately connected, some power was drawn, and then it shut off (this is a scheduled-overnight-charge location to use off-peak tariff). I presume it will charge, as normal, tonight. Although dashboard had not stopped working I did brake-plus-two-top-buttons until the dashboard fully rebooted. I had had an Email from TeslaFi "Car has been offline for 30 minutes" (which I ignored ) day-before-yesterday at 21:45 I periodically reboot "just in case", so it will have had a reboot at some time in the last few weeks. Anything to worry about? Seems a bit odd that the car let me plug in, but did not then charge. Never had dead-screen needing a reboot before (that I can remember, but I have had "screen reboots by itself on entry" at times) Car is on an ancient version (February) and I haven't got around to chasing support, again, as to why the car has not updated. That's another story though ... but there isn't a new-update that might have upset something.
