I’ve had a sleep schedule set for a few years and it’s worked without fail. I recently shut it down, disconnected it and moved it gently so I could dust the surface underneath it. I then put it all back together, and the following morning, it was off. It’s supposed to go to sleep at 2am and boot back up again at 6am on weekdays, and 8am on weekends. It has not woken by itself since, I have to disconnect and reconnect power each time. This has gone on for 3 days now, it always sleeps but won’t wake. I’ve tried clearing the sleep schedule and reconfiguring it, I’ve tried turning the sleep schedule off and then turning it back on, I’ve tried shutting it down, disconnecting the power, and reconnecting it in case I somehow failed to plug it back in properly. I’ve checked the timezone, that’s all still accurate. I’ve run a system test, which says there is a fault with the system clock but won’t tell me what the fault is or how to fix it. What else can I try?
