MacBook Screen going dark within seconds.
My MacBook Air M2 Sonoma screen is going blank/dark within 30 seconds if I do not tap a key or work the touchpad. I tap a key and the screen comes back on. This screen blanking did not start until I did a TimeMachine backup, not a restore, a backup.
The MacBook is set to go to sleep after one hour of inactivity not 30 seconds. The computer stays plugged to the adapter that is plugged to a USB C port.
Why after over a year of use would the screen start turning off after 30 seconds of inactivity?
MacBook Air, macOS 14.1
