My laptop Asus A510U out of the blue started making these faint beeping noises from underneath the keyboard 2 days ago. I thought it was only when charging, but when I unplug it, the beep is still there. It makes this 10 beeping sound in a somewhat consistent time interval. I have consulted a lot of people including store technicians but nobody knows what the issue is. Can anyone help me out? How do I solve this issue?
