| Swelling/Bulging | Battery case appears swollen or deformed, which can be a safety hazard |
| Failure to Charge | Battery won’t charge despite using working charger and proper connections |

Estimated Battery Life
Conservative estimates for 38Wh battery performance across different usage scenarios:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 3-4 hours |
| Document Editing | 4-5 hours |
| Video Streaming | 2-3 hours |
| Gaming | 1-2 hours |
| Idle/Standby | 6-8 hours |
Important Note: These are conservative estimates for a new battery used with older hardware. Actual battery life may be shorter than when your device was new due to increased power demands from software updates and natural hardware aging.
