Chromebook 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

If safe, note the battery-health information already available in ChromeOS and the charger model. Distinguish loss of charge during sleep from shutdown immediately after unplugging.

Stop point: A swollen Chromebook battery should remain switched off and unplugged.

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 matched pack after confirming the USB-C or charging path is healthy.

Related cause to rule out

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

Checks after the work

After repair or replacement, check charging, browser workload, sleep, restart and battery-only runtime.
