TP 355/360 - FRU Removals And Replacements
Applicable to: World-Wide
FRU Removals and Replacements:
This section contains information about removals and replacements.
The system board is sensitive to, and can be damaged by, electrostatic discharge. Establish personal grounding by touching a ground point with one hand before touching these units.
An electrostatic discharge (ESD) strap must be used to establish personal grounding.
Do not damage any part. Only certified trained personnel should service the computer.
The arrows in the "Removals and Replacements" section show the direction of the movement to remove a FRU, or to turn a screw to release a FRU. The arrows are marked in numeric order, in square call outs, to show the correct sequence of removal. When others FRUs must be removed before removing the failing FRU, 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 " for internal cable connections and arrangement information.
When replacing a FRU, use the correct screw size as shown in the procedures.
Safety Notice 8:
Before removing a FRU, power-off the computer, unplug all power cords from electrical outlets, remove the battery pack, and then disconnect any interconnecting cables.
Safety Notice 3:
The battery pack contains small amounts of nickel. Do not disassemble it, throw into fire or water, or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations.
Safety Notice 1:
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 flashes can cause electrical shorts.
Removal Models:
1010 Rear Connector Door
Remove the center latch 1; then remove the rear connector door by flexing it 2.

Notes:
1. Be careful that the computer does not fall backward when the battery pack is removed.
2. Check that the keyboard latch springs are in place.
1030 Diskette Drive:
Battery pack (1020)
Warning:

Important:
The EEPROM on the system board contains the vital product data (VPD), that is, system unit serial number, system board serial number, and other computer unique data. When the system board is replaced, the system unit serial number must also be restored. Use the Set system identification utility on the maintenance diskette to restore the number.
Do not power-off the computer when restoring the VPD.
The serial number label is attached to the bottom cover.
Notes:
1. Before removing and replacing the system board, make sure that the PCMCIA cards are removed and the eject levers are not sticking out.
2. When replacing the system board assembly, align the power-key slide hub with the power-switch actuator by moving the power-key in the direction of the arrow. See the large circle in the figure. Before tightening any screws, check that the power-switch operates correctly.
3. Do not pull the PCMCIA slot assembly while removing the system board.

Warning:
The system board can be damaged if the lower shield touches the system board components. Carefully follow the next instruction.
In step 4, gradually raise the system board from the lower shield until all the components of the system board just clear the tabs of the lower shield. Be careful not to raise it too far. While keeping the clearance to a minimum separate the system board from the lower shield by moving the system board straight forward as shown by step 2.
Notes:
1. When handling the PCMCIA slot assembly, be careful not to disassemble any part of it. The slot assembly is not solidly fixed when it is removed from the system board or the FRU.
2. The screw stand-off located each corner of the PCMCIA slot, is easy to remove. Make sure that the screw stand-off is positioned when replacing the slot. Do not replace the slot without the screw stand.
