Hi! My xiaomi notebook pro 15.6" occasionally has sounds (like a loud sound then stop for a few seconds then another) coming from the bottom. I'm not sure if it's overheating because it happens very randomly, sometimes when I first turn it on, sometimes when it has been turned on for a while. I had previously changed the ssd as it became spoilt and I did ask the repair centre to look out for this issue but they didn't face it. Any ideas? Much appreciated!
