Hello, I am having Gateway NV5378u laptop in my home. Now I am getting some of the unexpected problem. If you connect or disconnect the power adapter, it gives the loud beep sound. It simply like as the Windows xp error big. I want to know the solution from which I will able to remove the sound by making use of the disabling of it. If you are having any kind of solution then please provide that to me. Thank you in advance.
