How to use

Power down the notebook and disconnect any external power sources before replacing the internal battery. Remove the service panel according to the notebook manufacturer's maintenance instructions, replace the depleted battery with the new Lenovo 86Wh internal pack, and reconnect any battery connectors or securing brackets. Reassemble the notebook and connect the AC adapter to allow the system to calibrate the new battery and charge it to full capacity.
