i get back to school after a month break, i left the 4.1s at school, ( i craved them over break) i downloaded the docs from creative, hooked em up, and noticed that i have no power. i dissconnected everything, tried a dfferent power outlet and still nothing. the only thing i cant think is maybe a power surge at school over the break? I got these as a gift friom my parents about 3 months ago. anything else i should try?
