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
1The 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.
2Some computers may freeze when accessing a device in the media bay while using certain PC cards that draw higher levels of power.
3Theplasticsmaycrack.
4Some computers may take twice as long to boot when plugged into AC power as compared to booting from battery only.
5Some computers on larger LocalTalk networks may experience devices dropping off the network.

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

• 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.

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