Troubleshooting
PowerBook 2300 Series
Troubleshooting General - 1
General
The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts 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.
(Note: If you have replaced a module, reinstall the original module
before you proceed to 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 Flowchart for the product
family.
For additional assistance, contact Apple Technical Support.
Troubleshooting Battery Contact Alignment - 2
Battery Contact Alignment
Use the Duo battery contact alignment tool in these situations:
• Any time a battery contact screw is loosened, removed, or
replaced.
• Whenever a PowerBook Duo logic board is installed or
reassembled into a system.
• Whenever a PowerBook Duo with a known good battery shuts
down unexpectedly (other than going to sleep), won’t boot off
the battery, or intermittently powers off when running off the
battery.
• Any time a known good PowerBook Duo battery won’t charge.
Troubleshooting Power Manager Reset - 3
Power Manager Reset
If a unit crashes or experiences power problems, reset the power
manager chip by pressing the rear power switch for 30-45
seconds.
If resetting the power manager chip does not solve the problem,
reset the code for the power manager chip by removing all power
sources and letting the unit sit for 10 minutes. (Take out the
battery and disconnect the AC adapter and the internal backup
battery.) This forces the PowerBook Duo to reload the power
manager code from the system software.
Troubleshooting Symptom Charts/Startup - 4
Symptom Charts
Startup
RAM failure occurs
(eight-tone error
chord sequence
sounds after startup
chord)
1 Attach power adapter.
2 Check RAM expansion card connection.
3 Replace RAM expansion card
4 Replace logic board.
Note:
When replacing the logic board, check that the serial port
EMI clip is attached to the bottom of the CPU stiffener. If it is
missing, replace the stiffener. On international units, also
replace the stiffener if the modem EMI clip is missing. The “CPU
Stiffener” topic in Take Apart helps you locate and identify the
two EMI clips.
Note:
Perform the battery contact alignment procedure when
you replace a logic board. (See Additional Procedures “Align
Battery Contacts.”)
Troubleshooting Symptom Charts/Startup - 5
Hardware failure
occurs (four-tone
error chord sequence
sounds after startup
chord)
1 Check that mylar tape on docking connector is attached and in
place.
2 Disconnect hard drive cable from logic board and reboot
system. If startup sequence is normal, power off system,
reseat cable, and retest.
3 Check for sound from spinning hard drive.
4 Replace hard drive.
5 If system is connected to any external device, disconnect
device and reboot system. If startup sequence is normal,
reseat device’s cable and retest.
6 Replace logic board.
Note:
Perform the battery contact alignment procedure when
you replace a logic board. (See Additional Procedures “Align
Battery Contacts.”)
