2: Removing and Installing System Components
Removing the Baseboard
To remove the baseboard, follow these steps:
Caution: The baseboard can be extremely sensitive to ESD and always requires careful
handling. After removing it from the system, place it component-side UP on a
non-conductive, static-free surface to prevent shorting out the battery leads. If you place
the board on a conductive surface, the battery leads may short out. This will result in a
loss of CMOS data and will drain the battery. Do not slide the baseboard over any
surface.
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Turn off all peripheral devices connected to the system.
3. Turn off the system power by pressing the power on/off button on the front panel,
and unplug all AC power cords.
4. Label and disconnect all peripheral cables attached to the I/O panel on the back of
the system.
5. Remove the front cover. See “Removing the Front Cover” on page 23.
6. Remove the top cover. See “Removing the Top Cover” on page 25.
7. Remove the foam cover that shields the E-Bay.
8. Remove the fan board assembly. See “Removing the Fan Board Assembly” on
page 39.
9. Remove the memory retention bar. See “Removing the Memory Retention Bar” on
page 26.
10. Remove the memory module. See “Removing the Memory Module” on page 55.
11. Disconnect internal cables to the baseboard. Cables and connectors include:
• ThreeribboncablesatthefrontoftheE-Bay
• Three power connectors
• A ribbon cable located next to the non-hot-plug PCI add-in boards at the back of
the E-Bay
• A 13-pin AUX-IMB connector
