PowerBook G4 (15-inch FW 800_1.5/1.33GHz) Adjustments
Latch Adjustment
Procedure
Note:
The latch mechanism under the top case of the computer has a small amount of
right and left play (less than 1 mm), and can shift during normal operation.
The following procedures will test the latching function with the latch mechanism at its
maximum right and left positions, and the latch hook will be very slightly bent, as
necessary.
Important:
The latch hook metal can become brittle and break if it is bent too much,
especially if it is over-bent and bent back. Work carefully and with restraint to avoid over
bending the latch hook. If the latch hook breaks, the entire display panel assembly will
need to be replaced.
1. Open the display and use a black stick to push the latch mechanism, at the location
shown, to move it to the right as far as it will go (less than 1 mm).
Note:
You may not notice movement if the latch mechanism was already in this
position.
Note:
In this position, the latch mechanism has the least overhang available to catch
the latch hook, so this would be the “worst-case” position.
2. Perform the testing procedures in step 1 of the Preliminary Steps, above.
3. If the latch functions properly, skip to step 7, but refer back to the procedures below, if
the latch hook requires an adjustment.
