I have an acer nitro 5 (AN515-52 to be specific). I used to get a beep sound when I connected my charger or unplugged it but not anymore. I had been getting that sound for 8 - 9 months now, but it suddenly stopped playing. The beep sound was helpful as if I was in full screen mode I would I get to know if my charger was plugged in or not! Please provide me with a solution of you have any!
