Why does my laptop only last 2-3 minutes without a power adapter?
MacBook Air (13-inch, 2017)
Processor 1.8 GHz Intel Core i5
Memory 8 GB 1600 MHz DDR3
Graphics intel HD Graphics 6000 1536 MB
It’s been shutting down unexpectedly. At first, it was every 1 hour or so, than minutes, so on and so forth.
I’ve tried an SMC reboot, NVRAM, reinstalling macos. I did a hardware check (holding d on the keyboard when powering on). They said it could be the power adapter so i changed it, only for it to say that no issues were detected.
Battery condition, it says normal and with a cycle count of 731.
What could be the issue? Could the battery be faulty regardless of what the mac says?
