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.
