Program Overview

The PowerBook 5300/190 Repair Extension Authorization (REA) program provides instructions for resolving specific quality issues that customers may experience on the PowerBook 5300 and 190 family of computers.

Note: Not every PowerBook will be affected by each issue covered under the program, and a customer's PowerBook need not be exhibiting symptoms to be eligible for repair.

Symptoms Addressed by the Program

1 The AC power connector on the logic board can become loose or inoperative as evidenced by the inability to fully insert the AC adapter plug into the PowerBook.

2 Some computers may freeze when accessing a device in the media bay while using certain PC cards that draw higher levels of power.

3 The plastics may crack.

4 Some computers may take twice as long to boot when plugged into AC power as compared to booting from battery only.

5 Some computers on larger LocalTalk networks may experience devices dropping off the network.

Before repairing a unit, check whether it qualifies for repair under this program. Use the following guidelines to determine this.

Determine Whether a Unit Qualifies

Units That Don't Qualify

• If the unit has an REA label (consists of the letters “AA”) and an ink date stamp, it has already been repaired. No further repairs are necessary, so the unit does not qualify.

To the left is a sample of an REA label.

16261E A 6200 ZP OCT 28 1996

8152513 A 6200 ZP OCT 28 1996

If the unit has an ink date stamp (consists of a series of numbers/letters and a date stamp), but no REA label, it has already been repaired. No further repairs are necessary, so the unit does not qualify.

To the left is a sample of an ink date stamp.

In the unlikely event that an REA label is not attached to this unit, attach one before returning the unit to the customer.

Units That Do Qualify

• If the unit has an REA label, but no ink date stamp, perform the procedures below:

• Replace the palm rest.

– Replace the center clutch cover and CPU stiffener.

• Replace the bottom case.

• If the unit has no REA label or ink date stamp, perform the procedures below unless the part does not meet a specified criteria:

– Replace the display bezel/housing on units with serial numbers xx622xxxxxx and below.

• Replace the palm rest.

– Replace the logic board on units with serial numbers xx605xxxx and below.

– Install a power supply shield on units with serial numbers xx605xxxxxx and below and no existing shield on the power supply.

– Replace the center clutch cover and CPU stiffener.

• Replace the bottom case.
