I believe that many Dell notebook enthusiasts will encounter such a situation, the power indicator keeps flashing after booting; and it flashes with the switching of different colors.

Dell notebooks usually light up in a fixed color after being powered on. When the lights of different colors flash alternately, it means that there is a problem with the power battery! You can check as follows:
1. Check the power cord connector. During the charging process of the laptop, it is easy to cause the power indicator to flash continuously due to improper connection of the charging power supply and poor contact. You can re-confirm whether the power cable is connected correctly.
