If the board is not showing any LED activity when connected to the PC, it could mean that it is in fact in a damaged state. Nevertheless, it could be a powering issue, maybe the USB port the customer is using is not providing enough power to turn the board on, in that case, I'd suggest him to use either another USB port that he is sure provides enough power or an external power supply.
Also remember that if he is using an Arduino Expansion board, the board has a micro switch, if this switch is facing the full-USB port, the board is in host mode and it will not be able to be powered through the micro-USB port.
