FRU Removals and Replacements This section contains information on removals and replacements, and locations. The arrows in the removals and replacements show the direction of movement to remove a field replaceable unit (FRU), or to turn a screw to release the FRU. The arrows are marked in numeric order to show the correct sequence of removal. When other FRUs must be removed before removing the failing FRU, they are listed at the top of the page. Go to the removal procedure for each FRU listed, remove the FRU, and then continue with the removal of the failing FRU. To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement. See "Locations" on page 583 for internal cable connections and arrangement information. Safety Notice 8: Translation on page 14 Before removing any FRU, power-off the ThinkPad Dock I and computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables. Warning: The main board, adapters, and circuit boards on the drives are sensitive to, and can be damaged by, electrostatic discharge. Establish personal grounding by touching a ground point with one hand before touching these units. Note: An electrostatic discharge (ESD) strap must be used to establish personal grounding. 574 IBM Mobile Systems - ThinkPad HMM Volume 3
