Chromebook Battery: worn battery cells. Age and charge cycles reduce usable capacity and voltage stability.

The distinguishing clue

Runtime falls steadily and the laptop may shut down when demand increases.

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: Check ChromeOS battery health, charger compatibility and behaviour through shutdown and sleep.

Targeted check: Compare full-charge capacity, cycle count and behaviour during a controlled discharge. If confirmed: Replace the confirmed worn pack and verify normal charging.

Repair boundary: Replace the matched pack after confirming the USB-C or charging path is healthy.

Related cause to rule out

When charging is blocked or interrupted despite normal room conditions, also consider Chromebook Battery: battery temperature-sensor fault before choosing a repair.

Checks after the work

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