Laptop only boots with AC, but functions with battery afterwards
I have an acer Nitro (i7-4720hq, 860m) and it has a new battery I put in it. But for some reason it boots for 5 seconds (on battery power) just to turn off. Then I boot it with the ac adapter and it boots fine, unplug it, then it works as it normally should on battery power alone. So I am confused why this is the case.
