A method, apparatus, system, and signal-bearing medium that, in an embodiment, receive service data at a computer system from an RFID tag, where the service data was sent to the RFID tag from an RF transmitter while the computer system was powered off. The RFID tag includes tag memory and an antenna, and the RFID tag is attached to the computer system. In another embodiment, the computer system sends the service data to the RFID tag, and the service data is received by an RF scanner from the RFID tag via the antenna while the computer system is powered off. In various embodiments, the service data identifies the computer system or a product within the computer system. In another embodiment, the service data includes log information associated with the computer system. In this way, in an embodiment, service data associated with a computer system, such as vital product service data and log information may be accessed and updated even while the computer system is powered off.
