Acer Swift 3: Battery 100% but shuts off when unplugged

Been having issues with my acer swift 3 battery lately, I've only had it for 3 years. Started when I would charge the computer past 100% it would shut off when I un-plug it. I solved that issue by enabling the 80% battery charge limit.

It was fine for a while, but now it's like the battery isn't charging anymore. The computer works fine when plugged in, but shuts off immediately once I un-plug the charger. The indicator light is permanently blue, and the battery icon is full. However, when I hover the mouse over it, it doesn't read 100 (I know, very strange). I've tried the battery reset (pressing down the pin, leaving it for 45 mins, and charging again) but the problem persists.

Is there anything I should try, or should i just bring it to repair?

There is no such thing as "overcharging a Li-Ion battery" unless you are using a wrong power adapter or USB-C charger not compatible with your laptop. The 80% battery charging limit is a myth touted on the internet by bloatware vendors, don't buy that hype, You either have an adapter issue or the battery is bad. There are ways to check both, check this forum for threads with these topics. Also reset your BIOS with F9 in BIOS and save settings on exit. Then uninstall the 2 ACPI battery drivers and reboot, and uninstall the battery limiter app.

You don't tell us which of the hundreds of different Swift 3 models you have. Your full model number is usually on the same sticker as your serial number, it should look something like SF3xx-xxx-xxxx. Many have a battery reset button behind a pinhole on the bottom of the case. You can do a reset of the battery's internal stats by first shutting down and disconnecting everything, including the charger. Use a bent paperclip or a SIM tool to press and hold the reset button for 15-30 seconds. Release the button and wait 15-30 minutes. Plug only the power back in and wait for the full battery indication. Then turn things on and do a Windows battery calibration. That involves running on battery until the system shuts down due to low battery, then recharging fully before starting up again. Each time you do that Windows will get a little better at showing correct numbers for estimated battery life.

Needless to say, if you do the reset and you still have the same issue, the battery itself has likely gone bad and you need to replace it. More often than not though with a machine that's only 3 years old it's just that the stats are all confused.
