preparation

Save your work and shut the computer down through the operating system, unplug AC power and every external device, and work on a clean, grounded, ESD-protected surface while sorting each screw by its original location. Handle every cable by its connector and put each one back in its own place during reassembly.

  1. Power the machine down. If you are unsure whether the machine is off or in Hibernation, turn the machine on, and after that shut it down through the operating system. (printed page 32).
  2. Detach every external device wired to the machine. (printed page 32).
  3. Cut the power by pulling the cord out of the wall outlet, and after that unplugging the AC adapter from the machine. (printed page 32).
  4. Take the battery out (the Battery section is on page 32). (printed page 33).

replacement

  1. Take the small service door (the Service doors section is on page 33). (printed page 41).
