Involuntary reboot log 10.20

1/1/2023

To celebrate the new year, a hard reset.

Machine didn’t wake from sleep on opening shell after a time away (screen was black, screen backlight was not on). Tried a few buttons and closing/re-opening, but in the end had to hold the power button down to hard reset.

I suspect a problem with the power supply. The battery is so weak now that even when at 80 or 90% it occasionally goes to sleep as though the battery were dead. Machine claims battery is at "58% health". Going to have to get it serviced soon, before Apple stops doing battery service on this model, but I don’t want to be without the machine for too long.

Despite this incident, the average time between failures for this machine is 94.4 days (up from 87.74), which isn’t bad at all.

Involuntary reboot log 12.4

12/21/2022

Screen went black and machine was unresponsive to key presses, power button, opening/closing, plugging/unplugging (tried Thunderbolt dock and also Apple-provided USB-C charger). After a couple hours of fiddling, eventually a long power button press (greater than 10 seconds) forced it alive again.

Even so, after this event machine is still one of the most reliable I’ve had to date, with an average time between failures of 142 days (only the Liferay machine was better, as it never had an involuntary reboot in its entire 844-day history).
