Hello Subha,
To assist you further with this issue, I would request you to help me understand if the buzzing noise that you hear from the ac adapter is when you connect it to the wall out let or to the port on the computer.
I would suggest couple of steps to isolate the issue.
Connect the ac adapter directly to the wall socket (no APC or surge protector) and then disconnect it from the computer and check if you get the buzzing noise.
Please try the step and write back to us, I would be glad to assist further.
