Acer predator ph315-2 won't charge
My laptop is 14 months old, out of warranty. It is Predator Helios 300 2019 model. My laptop turned off suddenly while power was there and battery charged at 40%. Then, next time I could turn it on, battery was ar 0% and it wasn't increasing. Initially it shows the animation of charging battery. Also, acer care center (software) reported battery condition as good.
I went for repair at 2 places. One of them checked with substituting several ICs but couldn't identify the problem. But he didn't find alternative battery so couldn't check if replacing battery will work. Can anyone help me out with where the issue is. Also, should I buy a battery to check if issue resolves on replacement?
