FRU Removals and Replacements (TP-770 - 9548/49)

FRU Removals and Replacements

  Before the computer is powered-on after FRU replacement, make sure all screws,
springs, or other small parts, are in place and are not left loose inside the computer. Verify this by shaking the computer and listening for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.

  The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water, or
short-circuit it. Dispose of the battery pack as required by local ordinances or regulations.

  Before removing any FRU, power-off the computer, unplug all power cords from electrical outlets, remove the
battery pack, and then disconnect any interconnecting cables.

  An electrostatic discharge (ESD) strap must be used to establish personal grounding.
