I want to buy an Asus Rog flow X13(GV301R) off the marketplace, but there is a problem, the seller said it was plugged in 24/7. It doesn't hold off battery alone anymore. Still, it is fully functional when plugged in, I messaged the seller about the battery and he said, “Off the charger, the computer will restart somewhere between like 5 and 45 minutes. The battery report is like 65% efficiency or something like that. I'm not sure if it's the battery that is the problem.” I was thinking about replacing the battery if I buy it, and I was wondering if I had bought and replaced the battery would it work?
