On battery power, when I close the lid after 1-2 hours I come back and start working. The MacBook is turned off / rebooted, the work starts with a gong and starts to run as after a reboot. How do I solve this?
Sleepmode set to 3.
MacBook Air 18, Big Sur 11.3.1
MacBook Air 13″, macOS 11.3
Hi there,
When you shutdown, it will have to come back on, which makes a chime.
Granted, I may have missed what you're asking since you posted wit the "Code Insertion" tool, which messed-up your text.
Cheers,
Jack
I have a MacBook Air (Retina, 13-inch, 2019) running Big Sur 11.3.
I finally found a solution to the annoying problem of my Mac restarting due to the sleep/wake failure.
Go to Settings/Battery/Power Adapter. Check the option "Prevent computer from sleeping automatically when display is off."
No more sleep/wake failures.
After logging into the system, the MacBook gives this error. Tried to reset smc, didn't help.
Sleep Wake failure in EFI
Failure code:: 0x00000000 0x0000001f
hibernation and sleepmode
