Instructions
Battery Calibration Cycle
It is recommended to perform up to three battery calibration cycles to ensure that the laptop’s battery has been fully calibrated.
- Start by plugging in the laptop’s AC Adapter to the wall outlet and the laptop. Ensure that the laptop has begun charging once the AC adapter is plugged in.
Note: Your AC Adapter might be a USB Type C or a Barrel style connector. - Allow the laptop to charge up to 100%. While the laptop is charging, you may use it.
- Unplug the AC adapter from the laptop and allow the battery to discharge. The laptop can be used during this time.
- Once the laptop’s battery has reached 6% or less, plug the AC adapter back in, and allow the laptop to charge up to 100%.
- Once the laptop has been charged up to 100%, this completes one battery calibration cycle.
