PowerBook 5300/190 REA Program Overview - 0

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.

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

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.

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.
