16 - PowerBook G4 (17-inch) Troubleshooting

Hardware Symptom Charts

Memory error message “The built-in memory test has detected an error”

appears on the screen

1. Run Apple Service Diagnostic Test. Note: If the failure is intermittent, run Apple

Service Diagnostic Test in loop mode (check looping options under Test Controls tab

and select only the RAM test under the Select Tests tab) for an extended time to test

the memory.

2. If the test can’t ﬁnd the memory or ﬁnds bad memory, inspect the bad DIMM. Verify

proper memory is being used. The PowerBook G4 (17-inch) uses PC2700 (also called

DDR333) DDR SDRAM SO-DIMMs with a maximum height of 1.25-inch (30 mm). If

improper memory is being used replace it. Otherwise, try reseating the DIMM and

retest. If still reported as bad, replace it.

3. Check the memory connector for damage (retention arms broken, connectors bent or

missing, connector lifted from logic board). If damage is detected replace the logic

board.
