If you are attempting to connect your laptop between 110 and 220 volt power outlets, you may be able to do so already, take a look at your power cord's transformer (brick) and read the input voltage. If you only can use 110 volt AC Input Voltage should read 115VAC. If you can do both, then it should read 110-225VAC.
If your power brick supports 220, then all you will likely need is a plug adaptor, found at many electronics store. If not, you wil need to stop in at a computer store or an import store and get an international transformer, which are set up to convert many different country plugs and many common voltages.
