Battery Installation Guidelines
1.Prepare Before Installation: While installing a battery is generally straightforward, it is recommended to watch online installation tutorials for your specific laptop model or seek assistance from a professional.
2.Follow Installation Procedures: Handle all components with care during installation. Be particularly gentle with the battery connector on the laptop motherboard; do not use excessive force. Any damage caused by improper operation is the user's responsibility.
3.If the New Battery Doesn't Charge: If the battery isn't charging after installation, try a power reset: remove the battery, unplug the charger, hold the power button for 15 seconds, and then reinstall the battery. Repeat this process if necessary.
