| Symptom | Description |

| Battery Won’t Charge | Laptop doesn’t recognize battery or charge level stays at 0% when plugged in. |
| Swelling/Bulging | Battery case appears swollen or distorted, which can be a safety hazard. |

Estimated Battery Life by Usage
Conservative estimates for the 57Wh battery under different scenarios:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 3-4 hours |
| Word Processing | 4-5 hours |
| Video Streaming | 2-3 hours |
| Gaming | 1-2 hours |
| Mixed Use | 3-4 hours |
| Standby/Sleep | 24+ hours |
Important Note: These are conservative estimates for a new battery used with older hardware. Due to increased power demands from modern software and natural aging of other laptop components, actual battery life may be shorter compared to when your laptop was new.
