Sometimes my MacBook won't wake up and I have to restart it. Sometimes it wakes up but has a flashing file folder on the screen. How can I fix this??
MacBook Air 13″, macOS 10.15
I suspect your hard drive is defective. Consider scheduling an appointment with a Genius at your Apple Store.
See If your Mac doesn't sleep or wake when expected helps. For the other issue, If your Mac starts up to a question mark.
What do you mean by "heating up"?? Did you mean "starting up"?
I think when your Mac is heating up it disconnects your Drive. You need to backup your drive first.
Then Reinstall your macOS & see if that helps. If that does't help then you probably you have a Hardware problem which is needed to be checked by Apple OR by Apple's Authorised Service provider.
There is no evidence that heating up causes the drive to disconnect.
