Did you activate the battery in the correct way? Please charge and discharge at least 3 times.

1. It can be solved by deep charge and discharge.
2. 2. Set the battery charging threshold: it can be set to 80% when charging starts and 100% when charging stops.
3. 3. Sometimes the battery cannot be fully charged, because the laptop battery is a lithium battery, it is easy to overcharge during the charging process, which will damage the battery or shorten the battery life. Therefore, manufacturers will protect laptop batteries from overcharge damage. The charging of the notebook computer can only be charged to less than 100%, which can protect the battery and extend the battery life.
