Hopefully they will adjust this in a future update.This was definitely very annoying for me. I have a glitchy monitor and the lack of a sleep indicator makes it hard to troubleshoot sometimes when I need to hard power it.
Same here, it feels a bit naff and un-Apple like to just stay on full brightness when the Mac is sleeping.I noticed it too and actually my expectation was that the power LED will blink or get dimmer.
Interesting. I have just woken mine out of 'sleep' to find that it had encountered a problem during the night and rebooted itself back to the logon screen. Not a great start but didn't have this with my previous 2019 iMac.I,
More than a led problem, there is a bug on standby. The machine does not turn off.
