I have the same problem with my T540p. Speakers make white noise unless they are turned off or headphones are connected. This notebook is a real piece of crap. Horrible touchpad, speakers and cooling system make it unusable. My 7 years old laptop works better than it. Lenovo seems to not care of its customers. Shame on you Lenovo!
I will never again make a mistake buying any of your products. I would like to return this notebook and get partial refund or another laptop.
