power, docked in an optional docking device, or connected to an optional power source. During the
download and installation, follow these instructions:
Do not disconnect power from the computer by unplugging the power cord from the AC outlet.
Do not shut down the computer or initiate Suspend or Hibernation.
Do not insert, remove, connect, or disconnect any device, cable, or cord.
