MacBook air shuts down abruptly while using directly with a charger, is it because I am not using battery backup?

[aadibean]

bought a MacBook air in 2018. After a few months, the battery stopped working and I started using it directly with a charger without any battery backup. Sometime later the device started to shut down randomly even when plugged in and especially when using software like Photoshop.

I am anyway planning to replace the battery but before that, I wanted to make sure is this shutdown issue related to battery or something else?

Did anyone face the same issue before?

Thanks!

I can't diagnose your exact issue but I'm pretty sure a dead battery can throw a wrench into the power works. Whether or not is has caused damage…I dunno.

Did you buy it new or used?

Without a working battery, the CPU speed is throttled by the OS.

It could be shutting down because the charger can't provide enough power for CPU-intensive tasks.

If it's a 2018, you will probably have to get Apple to replace the battery. If it's older, you might be able to do it yourself.
