Business Laptop Battery: heat-sensitive battery failure. Internal resistance or sensor error becomes worse as the pack warms.

The distinguishing clue

Charging or battery operation works from cold and stops after several minutes.

Checks before an assessment

Record whether the problem occurs with the direct charger, the office dock or both. Save open work before any normal power transition.

Stop point: Protect current work before disconnecting power during battery diagnosis.

Workshop confirmation and repair

Device-level check: Leave an unusually hot pack out of load tests and inspect the battery, its connection and surrounding thermal damage before any further charging.

Targeted check: Monitor temperature and voltage during a limited, safe load. If confirmed: Replace the heat-sensitive battery and inspect nearby cooling.

Repair boundary: Replace the supported battery and correct any dock or firmware condition that affected it.

Related cause to rule out

When runtime falls steadily and the laptop may shut down when demand increases, also consider Business Laptop Battery: worn battery cells before choosing a repair.

Checks after the work

After repair or replacement, check direct charge, dock charge, meetings workload, sleep and repeated transitions.
