Why does the Dell laptop not turn on the charger when it is unplugged, and it can be turned on when plugged in, and the screen power display is fully charged, ask God for advice.
Hello dear, this one is because the laptop battery is broken. Because, if the battery is broken, it will not store electricity. Therefore, it can only be used if the core is connected to alternating current.
As soon as the alternating current is unplugged, the computer will be disconnected and then shut down. The solution is to change the mountain trail and replace it with a new laptop battery. Of course, there is another reason, which is caused by poor contact between your battery and the laptop.

When a new laptop battery is first turned on, the battery itself should have more than 70 charges (this is also a common practice for manufacturers). If you open the laptop you bought for the first time and find that the battery is fully charged or more than 70% charged, it means that the manufacturer has done a factory test). At this time, you should fully charge the battery, the charging time must be more than 12 hours, and then set the battery to turn off when the battery is 5% power, and repeat it three times, so that the battery can be completely activated, which can effectively improve the service life of the battery. >>>More
