Since I got the xps13 I have a buzzing sound problem on the right side of the laptop.
I tried A7, A8,A9 and A10 BIOS and I tried the combination of Windows 7, 8 and 8.1 with those BIOSes.
I have same problem in every case.
When I press the F2 to enter the BIOS, the buzzing sound is getting higher and higher !
After OS started, there is no buzzing sound, as soon as I turn on the music or test the speakers (all drivers installed already and updated) , sound comes back at the same time.
Please help me to fix the problem, I cant use my XPS.
