How to use

Power down the laptop and disconnect it from the mains before beginning installation.

Reattach any panels and reconnect the power adapter. Allow the battery to charge fully before first use for accurate charge level reporting.

If the laptop shows charging anomalies after replacement, consult device diagnostics or authorized service options.
