I bought asus r510jx for music production. I operate this laptop for about 2 hours in a week (yes, very less usage). My problem is that when I shut down my laptop I hear weird beeping sound continuously. This sound doesn't come when I am operating the laptop. I am bit weird about this sound. Please help. I am posting the link of recorded audio of beep. http/vocaroo.com/i/s16tqmKVmlHA
