Look on the brick and see what kinds of voltage and frequency it takes.
For some time it's been common for them to take anything between 100 and 240V and 50 and 60Hz, which is basically worldwide.

My assortment of laptop power bricks from the last decade basically has no model specific brick that wouldn't run anywhere in America or Europe.

The only thing you should need is a different plug or an adapter.

here in switzerland we have 230V, so you think i just need a other plug, right?
do i have to switch some button?

As said, look on your power brick and read the specs yourself if you want to be sure. My way older power supply units from the TC4400 (grandfather of the 2730p) accept 100-240V~ and 50-60Hz, so yours should do, too.

And what button do you think of?
You mean a switch to throw for the different voltages?
I only know those from desktop PSUs. If your brick has one, it's there for a reason. If it has none and is specified for a range of voltages and frequencies, it has to take them without any modifications.

yes , i guess youre right, they work all over the world. do i have to compare only the volts, or also the Hz?

[Hattori Hanzo]

As Switzerland has 50Hz and the US have 60Hz: yes.

is that difference a problem?

No, it won't be an issue.... you are really not understanding what is being said above

Take a look at this


That is not the A/C adapter you will be using. But if the A/C adapter you get is a proper 'branded' (not 'Off-Brand') adapter then it should have the same text as in that picture [notice the little outlined box it says 100-240V and 50-60Hz] as long as its like that then you are good to go with simply using a different plug/ cable to plug into the wall as its all internalized and setup to work fine. If it doedn't state 50Hz and 240V somewhere then don't use that adapter

EDIT: lol, beat you to the punch Hattori

I wouldn't put a machine I'd still want to use on the business end of a power brick that is not driven within its specs.

Why don't you just take a look at the specs of yours already?
And yes, it almost certainly says 50-60Hz and hence should be working fine in the US, Switzerland, Italy, Germany, Poland, Spain and some dozen other countries.

Edit:
Yes, look at Agent9's picture.
Just below the Dell Logo in the white rectangle are the key electric specs.
INPUT tells you what it needs to get supplied and that is denoted as a range of voltages and frequencies.

Now go and look on your brick and look for those figures. That's the only (sane) way to determine what it can handle.
