Your battery may drain when connected to the AC adapter during heavy use. When your computer requires more power than the AC adapter can provide, it will stop charging to allow it to draw additional power from the battery. The system will resume charging the battery when the power demands are lower. This may occur during heavy gaming sessions.
Note: If the battery discharges below 30% while using the AC adapter, the system will stop using power from the battery until the charge is above 40% again.
