Hm, earlier I asked if my computer would work in the Philippines in a 220v socket and indeed, it does, and so does my monitor (both are able to receive and input of 100-240v) but i notice the brushed aluminum is tingly. This happened last year when I brought my laptop as well and I wondered what causes it and how dangerous is it? Hopefully not too dangerous because I used to use my laptop often and really didnt think it was due to the power last year.
