Won't accept charge, or battery drains quickly
I have tested the charging cable, which is not the problem, and fully taken apart the laptop, as well as tested the battery itself. both of those are not the issue, and I had the laptop working fine for 2 years before it started this. It does not accept a charge, and when it does, it may only charge to 50 or 75% then die out again, or not recognize that it is plugged in at all, and refuse to accept a charge entirely, as well as not even powering on even when plugged in. I was curious if it may be something to do with the motherboard, or the power port possibly being broken. As stated, I have tested the battery and charging cable and neither of those are the problem. Any help would be greatly appreciated.
