In that case, it could be that Win 7 requires a driver that either isn't installed or isn't working; or perhaps the USB port is disabled. Even without a driver, though, I'd expect the drive to power up; otherwise Windows would probably be unable to obtain the required device info. Do other devices work properly when plugged into the same USB port?

Another possibility is that the drive requires more power than your Vostro's USB port is able to deliver. That's not too uncommon and requires a powered hub to provide the power.
