Why is my Lenovo Saver computer suddenly charging slowly?

First, the 67 battery has been used for a long time and worn out. At this time, the performance will decline, the charging time will be longer, the use time will be shorter, and there will be problems such as virtual electricity. This may happen if the notebook is used for a long time.

Second, the power adapter is not plugged in, or there is something wrong with the power management circuit. Insert the power adapter carefully and try again. If not, go to the after-sales inspection.
