After I made the switch to Manjaro a few months back, I also installed Manjaro on two of my older laptops, which I only incidentally use. This morning, upon working on a project for my Pi, I needed my old laptops because of the SD card slot. However, I quickly found out that they wouldn’t charge and also wouldn’t boot. One of those laptops, which is very old, used to run Windows 7 until I put Manjaro on there a few months back. It always booted up until today, even when there were years in between. After the initial Manjaro installation a few months back, I don’t think I’ve booted these laptops, since they’re not my daily drivers.
What might be going on here?
