Chromebook Battery: incorrect replacement battery. A physically similar pack uses the wrong voltage, firmware, connector or identification.

The distinguishing clue

The laptop rejects the pack, charges abnormally or reports incorrect information.

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 the original battery code and full electrical specification. If confirmed: Install the exact supported pack and inspect for mismatch damage.

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

Related cause to rule out

When the pack is identified but will not accept or deliver normal energy, also consider Chromebook Battery: battery protection lockout before choosing a repair.

Checks after the work

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