Hi, We've had this problem since long. My lappy seems to be a good recording platform, specially since we've only made single tracks yet. The problem is that whenever I put my lappy on charging and try recording, there's lot of unbearable noise in the recording. But its good when I record without plugging in the charger. Its quite frustrating because I've to make sure that my lappy's fully charged before recording. And if it gets discharged while doing it, well, wait for it. Laptops are really good as far as portability is concerned. We even did songs on a building terrace. Why's there so much noise? What to do to prevent it? Solutions?
