FRU Removals and Replacements This section contains information about removals and replacements. Do not damage any parts. Only certified, trained personnel should service the computer. The arrows in this section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal. When other FRUs that must be removed before the failing FRU is removed, they are listed at the top of the page. To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement. See "Locations" on page 503 for internal cable connections and arrangement information. When replacing a FRU, use the correct screw size, as shown in the procedure. Safety Notice 1: Translation on page 8 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. Safety Notice 3: Translation on page 10 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. Safety Notice 8: Translation on page 14 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.

Dispose of the battery as required by local ordinances or regulations. Use only the battery in the appropriate parts listing. Use of an incorrect battery can result in ignition or explosion of the battery. 454 IBM Mobile Systems HMM
