Possible Repairs
If your 97Wh Dell laptop battery is not charging, the following repairs may help:
Check the Power Adapter
The first thing you should check is the power adapter. A faulty power adapter may not supply enough power to charge the battery. Try using a different power adapter to see if the problem is with the adapter.
Check the Battery Connector
If the power adapter is working fine, check the battery connector for any damage. Look for any bent or broken pins, and make sure they are properly connected. If the connector is damaged, you may need to replace it.
Check the Battery
If the connector is fine, the problem may be with the battery itself. Try charging the battery outside of the laptop using a USB charger. If the battery charges, then the problem is with the laptop's charging circuitry. If the battery does not charge, then the battery may be faulty and need to be replaced.
Check the Charging Circuitry
If the laptop's charging circuitry is the problem, you may need to replace it. This is a more complex repair and may require the help of a professional technician.
The 9-pin connector is a common type of connector used in Dell laptops, including the 97Wh battery. Understanding the pinout of this connector can help you troubleshoot charging issues. If your battery is not charging, check the power adapter, battery connector, battery, and charging circuitry to identify and repair the problem.
