Macbook Pro and Air won't turn on and won't charge.
So my MacBook pro 2020 which I'm using for 5 months and my sisters MacBook air 2020 which she is using for over a year won't turn on and won't even charge, we've taken good care of the units and this happens. it didn't even last long, Good thing mine is still under warranty but my sister isn't anymore. We had mine diagnose and they couldn't find out why if they wouldn't replace the parts, I ask the support and they said they don't know too. It's so bizarre that this happens both at the same time? Are there anyone who has the same problem? Repair cost too much.
MacBook Pro 13″, macOS 12.4
