Troubleshooting
 
General
 
In each service manual on Service Source, you will find 
Flowcharts and/or Symptom Charts designed to help you 
diagnose and repair Apple computers.
If you have narrowed the problem down to a particular 
symptom, start with the Symptom Charts. Because cures are 
listed in the order of most likely solution, try the first cure 
first. Verify whether or not the product continues to exhibit 
the symptom. If the symptom persists, try the next cure. 
If you are not sure what the problem is, or if the Symptom 
Charts do not resolve the problem, refer to the Flowcharts.
Diagnostic tools are also available to help you isolate a 
hardware problem. Refer to the Diagnostics page of Service 
Source, which you can access on Service Source CD or at 
Service Source Online (http://service.info.apple.com).
If you require additional assistance, contact Apple Technical 
Support. 
						

							 
General / Power-On Self Test -  
2 
Troubleshooting 
PowerBook (FireWire) 
Power-On Self Test 
There is a power-on self test that resides in the ROM of the 
PowerBook (FireWire). This test automatically runs 
whenever the computer is powered on after being fully shut 
down (the power-on self test does not run if the computer is 
only restarted).
If a problem is detected during the test, you will not hear a 
normal startup chime. Instead, the system will beep as 
explained in the Power-On Self Test Beep Definitions chart. 
Power-On Self Test Beep DeÞnitions 
BeepsDefinition
1 beep No RAM is installed or detected.
2 beepsEDO memory is installed. The PowerBook (FireWire) 
ships with SDRAM SO-DIMMs and does not accept EDO 
memory. 
3 beeps No RAM banks passed memory testing. 
4 or 5 beepsBad checksum for the remainder of the boot ROM. The 
ROM (which is located on the microprocessor module) 
is bad. 
						

							 
General / AirPort -  
3 
Troubleshooting 
PowerBook (FireWire) 
AirPort 
Verify you are using the latest AirPort software. In the U.S., 
this should be at least AirPort 1.1.
Always make sure the antenna cable connector is plugged in 
fully. There should be no space between the base of the 
connector and the edge of the AirPort Card.
For AirPort troubleshooting help, refer to the 
Troubleshooting chapter of the AirPort service manual on 
Service Source. 
Battery VeriÞcation 
PowerBook (FireWire) batteries have level-indicator lights 
that show whether the battery is fully charged, three-fourths 
charged, one-half charged, or one-fourth charged.
To determine the actual battery charge, push in the level 
indicator button to activate the indicator lights.
If more than one light is blinking, there is a problem with the 
battery. If only one light is blinking, the battery is fully 
depleted and should be charged soon. 
Note: 
 If it seems that the lights are not reporting levels 
correctly, fully discharge the battery and then recharge it to

Troubleshooting 
calibrate the battery. After this calibration, the lights will 
report charge levels properly. 
Backup Battery VeriÞcation 
The backup battery saves the PRAM and power management 
information on the I/O logic board when the computer is shut 
down. To check that the backup battery is working:
1. Verify backup battery is connected to the I/O logic board. 
2 . Set the date, time, and time zone.
3. Select Shut Down from the Apple menu or Special menu.
4 . Remove the main battery and disconnect the power adapter 
for 10 minutes.
5. Connect the power adapter, insert the battery, and power 
on the computer.
6. If the date and time were lost, the backup battery may be 
dead or discharged.
7. To recharge the backup battery, leave the computer 
plugged in for 48 hours. It is OK to use it while it is 
charging.
8. If the backup battery appears dead or will not charge, 
replace the backup battery. 
						

							 
General / Reset PRAM -  
5 
Troubleshooting 
PowerBook (FireWire) 
Reset PRAM 
Important:  
Resetting PRAM erases the contents of the RAM 
disk, if there is one. Resetting PRAM also restores the default 
settings in most control panels. After you reset PRAM, be 
sure to check any custom settings for the desktop pattern, 
memory, network, AppleTalk, trackpad, power conservation, 
and so forth. 
To reset PRAM:
1. Power on the computer by pressing the Power key.
2. Immediately press Option-Command-P-R. 
3. Press the four keys until you have heard the startup 
chime at least one additional time after the initial startup 
chime. 
Reset the Power Manager 
PowerBook (FireWire) computers have a reset button located 
on the back of the computer behind the I/O door. Press the 
button once to reset the power manager.
