Lenovo ThinkPad L390 Battery Not Charging

Is your Lenovo ThinkPad L390 battery not charging even when plugged into a functional charger? Use this troubleshooting guide to help diagnose why.

If your Lenovo ThinkPad is not charging properly, the charging port might be the issue. Here are some steps to address potential charging port problems:

• Check for Loose or Damaged Ports- Ensure that the charging port on the Lenovo ThinkPad is not loose or damaged. A loose connection can prevent proper charging.
• Inspect for Debris: Debris or dust accumulation inside the charging port can interfere with the connection. Gently clean the port using a soft brush or compressed air to clear any blockage.
• Test with a Different Charger- If the charging port appears fine, test the Lenovo ThinkPad with a different compatible charger. If the issue persists, the problem may lie within the charging port or internal hardware.
• Avoid Excessive Force- When inserting the charging connector, make sure to not use excessive force as it can damage the charging port over time.
• Port Replacement- If the charging port is physically damaged, it may need professional repair or replacement.

If you are experiencing internal issues with the Lenovo ThinkPad here are some helpful tips to solve that issue:

• Reset the Device - If the device is running slow and not operating as it should all you may need to do is just power down and hard reset the device.
• Lenovo ThinkPad Crashing Issue- If you experience this often it may mean that your device is running out of memory, and it is best to clear space in the system.
• Faulty Battery Sensor - Battery sensor not properly picking up the charge from the battery may be due to the battery sensor being faulty and it is best to replace it.

If you are failing to get a charge or experiencing quick battery drainage while the Lenovo ThinkPad is plugged in, and the charger/port is working fine, check your battery to see if it is working fine.

• Battery Age - If your device is 2-5 years old or has already gone through 300-500 charge cycles, your battery may need to be replaced.
  • Before replacing the battery, check to see if it is swollen and properly dispose of it.
• Check Resource Usage- Closing open applications will help the battery from draining so quickly.
• Check the Battery Temperature - Constant overheating can increase the decline of your battery, so If your battery is constantly overheating, check to see if your cooling system is working properly.

If you are failing to get a charge while your Lenovo ThinkPad is plugged in, after checking other causes, use these steps to fix any charger related issues:

• Check Connections - Check the charger connections to the Lenovo ThinkPad and outlet for any loose connections that may be stopping the Lenovo ThinkPad from charging.
• Inspect the Charger - Check the connection piece of the charger for any debris or damage.
  • If the charging pins are damaged or corroded, the charger must be replaced.
  • If there is a lot of debris, carefully clean the connection piece to allow better connection.
• Test the Charger - Try using the charger with a different device. If it charges the other device, the problem may lie in the Lenovo ThinkPad itself.
• Check the Specifications - If using a different brand of charger than the provided Lenovo ThinkPad L390 one, make sure the specifications match the original charger.
  • Differing specifications may cause less efficient charging or no charge.
