so im going to be taking my thinkpad t60 to europe and the middle east on a business trip and the voltage where i am going is apparently 230 volts whereas here it is 110 or something like that. the a/c adapter with my computer says it does a range of 110-240 and friends have told me this means it is dual voltage and i can use it in those countries with nothing more than an adapter plug but some dude who works for ibm told me that i need a transformer to downgrade the voltage so that it does not damage my computer. ne tech savy guys here wanna tell me the real story?
