Closing the case
The following instructions describe how to close the case.
1. Recheck all connections to all PCAs. Be sure all connectors are fully
seated and latched, and all metal bails are properly installed.
2. Make sure the Data Card ejector button is pressed fully in.
3. Orient the unit flat on a smooth surface so the handle is closest to you,
with the bottom case on the left next to the top case. See "Case Opened"
on page 4-26.
4. Flip top case over to the left into a rightside-up position over the bottom
case. Lower top case straight down, with front edge first to give extra
room for the ejector button. Mate top to bottom.
5. Carefully check around all mating edges of the case for any gasket, wires,
etc., sticking out between the case halves.
6. Turn the case upside down (holding the halves together with your hands)
and shake it to double check for loose hardware inside.
7. Place the unit on the work surface upside down.
8. Replace the 1 T15 case screw located in the battery compartment.
9. Replace the Battery Cover as described in "Battery Cover" on page 4-15.
10. Turn the unit over rightside up. Install a battery. If the battery does not
readily latch into place, check for a case screw or other hardware lodged
against the battery PCA. Also check that the Battery PCA is installed cor-
rectly.
11. Turn on power and run an Extended Self Test before installing the rest of
case screws (see "Extended Self Test" on page 2-17).
12. Remove the battery.
13. Turn the case over and replace the remaining 11 Torx T15 screws in their
holes and tighten snugly.
14. Perform Performance Verification Testing as described in "Performance
Verification and Safety Tests" starting on page 2-1.
