So I'm using a Lenovo W520 bought in the states while studying in Berlin. I just arrived, and even though my power converter/adapter handles the change from 230 (or is berlin 220...) to 110, and the brick says it works with 100-240, my power cable brick is buzzing. It's not heating up any more than usual, and the only side effect is the buzzing, but it makes me a little concerned.
There doesn't seem to be any mention of buzzing, and most things I've found tend to show that things are ok with lenovo laptops if you use a converter, but I just want to make sure. Any help would be greatly appreciated.
Solved! Go to Solution.

Plug the PSU directly into the wall socket (get the adapter plug for Germany). The buzzing is happening because your 220/110 convertor that is not producing sine wave power.

That sounds like a good idea... now if I can find an adapter that is not a converter with my limited German... that will be a miracle.
Until then, do you think its an issue to use the converter I have inspite of the buzzing sine wave?

Sorry, didn't see this before I posted. It is not exactly loud... its like a large fly constantly buzzing around my feet. Its useable as far as noise goes, but this laptop has to get me through graduate school, so I don't want to damage it obviously.
