You can follow the steps in this video to troubleshoot your battery:

1. Central Pin: In many laptop power supply connectors, especially those using the barrel-type connector, there's a central pin that carries the voltage (typically around 19 volts for most laptops) to power the device.
2. Voltage and Polarity: It's crucial to ensure that the voltage supplied by the power adapter matches the requirements of your laptop. Most laptops operate on 19 volts, but there are exceptions, so always double-check the specifications of your laptop and the power supply.
3. Polarity: Additionally, the polarity of the connector is important. The central pin typically carries positive voltage, while the outer sleeve of the connector is the ground (negative). Reversing polarity can damage your laptop, so make sure the connector is inserted correctly.
4. Safety: Always use the power adapter that came with your laptop or a compatible replacement from a reputable manufacturer. Using an incorrect or incompatible power adapter can not only damage your laptop but also pose safety hazards such as overheating or electrical fires.
5. Replacement: If you need to replace your laptop's power adapter, ensure that the new adapter provides the correct voltage, polarity, and wattage for your laptop model. It's often safer to purchase adapters from the laptop manufacturer or certified third-party suppliers to guarantee compatibility and safety.
