1. Check if the battery is covered under a repair
extension program. Use the “Portable Computer
Battery Screening Process for Apple Service
Providers” (Knowledge Base CP165).
2. Verify no applications have runaway processes
with the CPU. See “Runaway applications can
shorten battery runtime” (Knowedge Base
TS1473).
3. Use “Apple Portables: Battery Life” (Knowledge
Base HT1466) to screen for short battery run
time. If replaced for run time too short, regardless
of warranty coverage, use symptom code P09 if
replaced.
