Hello! I just got a MacBook air but I'm having a problem and there is literally no answer anywhere on the internet to my problem, so i thought i would join a forum and see if anybody in the world has ever had this problem-- when my battery goes lower than 80% the laptop slows down so much and it keeps getting worse for every percent drop that you would think it only has 10kb of ram, as soon as I plug it in, the laptop runs normally within 2 seconds. What could be the problem? I don't think it's the battery cause i can use it for almost an hour from 100% to 80%
