Windows 10: Laptop will only turn on when plugged in, instantly turn off when unplugged, and will not...

I own an older 2018 Asus ROG Zephyrus GU502GV and suddenly very recently I have been experiencing the issue described in the title and I see it as extremely odd and very sudden. Initially I thought this must be some sort of display bug but it truly wont charge above 3% and when the charger is plugged in will instantly turn on, I refuse to believe that the laptop battery has finally gone out as I never experienced this and it just seemed to happen. Is there any fixes for an issue like this or similar? If more information is needed please ask, my hardware is as follows:CPU: 9th gen i7GPU: NVID

Laptop turns itself back on when unplugged

When I turn my laptop off and unplug it, it turns itself back on. If I shut it down while unplugged, it immediately restarts. If I shut it down while plugged in, it stays turned off. Need help to sort this please.

 

Turned on automatically when plugged in and off when unplugged

Laptop just start misbehaving. It won't turn on except when plugged in, and it will off when unplugged despite displaying 94% at the battery bar.
