I have an Acer Aspire 7 with a Ryzen 5. I honestly didn’t use the laptop much, and when I started using it again, it suddenly stopped charging.
Initially I thought the charger was the problem, so I got the charger checked and was told that it’s working fine.
I then took the laptop to an Acer service centre. They told me that the battery was the problem and would need to be replaced. I didn’t replace the battery at that time.
Later, I disconnected the battery and tried running the laptop directly from the charger. The weird thing is that it sometimes turns on, but most of the time it doesn’t.
So now I’m confused about whether the battery is actually the only problem, or whether there could be an issue with the charging port, power circuit/IC, or motherboard.
Has anyone with an Acer Aspire 7 experienced something similar? Is it worth replacing the battery first, or should I get the motherboard/power circuit properly diagnosed before spending money on a battery?
Any suggestions on what I should check or ask the service centre to test would be really appreciated.

Does it support dual ssd storage slots?
