The macbook air and a 16-inch m1 pro I bought a few months ago after the national subsidy all have similar problems. Whether they are placed in a schoolbag or on a laptop stand, they are hot after sleeping. After starting it, it turns cold. The air has no fan, and it is even cooler when using it than when not using it. It is very puzzling. Have you ever encountered a similar situation? How do you need to deal with it?

When waiting to be turned off, you should pay attention to whether the screen really changes from dark gray to a real black screen and avoid accidentally touching the keyboard/second control panel. It is turned on again after the box cover is closed (of course, it is indeed in a sleep state after the box cover, but it will indeed heat up slightly if you reply as above) Last year, I observed that if a fully charged M3 Air does not shut down but sleeps, the battery drops to about 30% in about 10-15 days

Anonymous689 Jun 6, 2025My current Mechanical Revolution notebook also has this problem. It doesn't support S3 sleep. After forcibly turning it on, the CPU usage rate remains high during sleep, but when the fan stops, it feels very hot to the touch. The CPU usage rate is very low under normal use
