power adapter is connected. Changing the battery while the system
is in sleep mode, without a power adapter, will result in a loss of
all data stored in RAM.
The iBook has no backup battery. Therefore, shut the
Sleep
There is an option in the Energy Saver control panel called
“Preserve memory contents on sleep.” When this option is
selected, the system creates a file containing all the information
contained in RAM at that time, and stores it on the hard disk before
going into sleep mode.
Battery Verification
When the power adapter is being used, the ring around the power
adapter port glows green when the battery is fully charged. The
ring glows amber if the battery is being charged.
You can also check the battery status by looking at the Battery
portion of the control strip or the battery symbol in the upper
right corner of the Finder menu bar.
Power Adapter Verification
Try using a known-good power adapter if the computer cannot run
off the existing one, or try the existing power adapter with
another iBook or G3 Series PowerBook
Under normal operation, the ring around the power adapter port
will glow green or amber if the computer is receiving adequate
power.

Symptom Charts
How to Use the Symptom Charts
The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to the product.
The steps to solve a symptom are listed sequentially. You might not
need to perform every step before the symptom is solved. Start
with the first step, and then test for the symptom. If the symptom
persists, replace any modules you removed, go to the next step,
and test again. Continue down the list until the symptom is solved.

Troubleshooting Symptom Charts / Error Beeps - 6
Error Beeps
The computer automatically performs a power-on self test when
it is turned on after being fully shut down (not a restart). This
section describes what to do if beeps are heard during the startup.
Note:
The iBook and iBook (FireWire) have one memory
expansion slot. Refer to the Memory Replacement instructions for
removal and installation.
Computer beeps once
at startup
Computer beeps twice
at startup
Computer beeps three
times at startup
Computer beeps four
times at startup
1 One beep means that no RAM is detected.
2 If a RAM card is installed in the expansion slot, remove it and
put in known-good and compatible RAM and restart.
• If symptom does NOT repeat, replace RAM card.
• If symptom repeats, replace logic board.
3 If no RAM card is installed, replace logic board.
1 Two beeps means that EDO memory is installed in the
expansion slot. The iBook does not accept EDO memory.
2 Replace RAM card with known-good and compatible RAM and
restart.
• If symptom repeats, replace logic board.
1 Three beeps means that no RAM banks passed memory testing.
2 If a RAM card is installed in the expansion slot, remove it and
put in known-good and compatible RAM and restart.
• If symptom does NOT repeat, replace RAM card.
• If symptom repeats, replace logic board.
3 If no RAM card is installed, replace logic board.
1 Four beeps indicates a bad checksum for the remainder of the
boot ROM. The ROM (which is located on the logic board) is
bad.
2 If a RAM card is installed in the expansion slot, remove it and
put in known-good and compatible RAM and restart.
• If symptom does NOT repeat, replace RAM card.
• If symptom repeats, replace logic board.
3 If no RAM card is installed, replace logic board.

4 Replace modem.
1 Use the Modem Country Selector utility to make sure the
modem is set to the correct country.
2 Make sure the correct driver is installed and the correct CCL
is selected and that they are not corrupted. If necessary,
reinstall the driver and/or CCL.
3 Try another cable and phone jack.
4 If problem persists, reinstall system and modem software.
1 Use the Modem Country Selector utility to make sure the
modem is set to the correct country.
2 The phone line may have too much noise. If the user has a
second line, try that one. The user should contact their local
phone company and request their line be checked.
3 Check to make sure the TCP/IP control panel is correctly
configured for the user's Internet Service Provider. If the
TCP/IP control panel is not configured correctly, it may
connect but won’t be able to access any sites.
4 Sometimes online services use different servers for dial-up/

1 Use the Modem Country Selector utility to make sure the
modem is set to the correct country.
2 Try another cable and phone jack.
3 The phone line may be too noisy to handle the higher modem
speeds. Try connecting at a slower speed or use a generic CCL
file. (If you are familiar with the CCL script language, you
can edit the modem script to force a connection at a lower
speed.) If the problem continues, contact the phone company
to report the bad phone line.
4 Verify that the user has call waiting on that phone line. With
call waiting active, an incoming call can interrupt the
connection. Disable call waiting using AT commands placed in
the init string of the dialup application. Usually the string is
*70.
5 There may be a problem with the server to which you are
connecting. Servers sometimes develop problems that
disconnect users without explanation. Try calling back later
or use an alternate number if one is available.
6 Check with the Internet Service Provider.
