Many friends have encountered such a problem. When your laptop is connected to the power supply, a prompt "Power is connected" appears. "Not charged", so what should we do in this situation? This situation will cause the laptop battery to be unable to charge. Laptop users have a habit of plugging the power supply directly into the computer when using the computer, and it is very uncomfortable after using the computer. Don't unplug the power supply. After a long time, you will find that the laptop's battery is no longer durable. So what's wrong with the laptop when it's plugged in but not charging?
First, let’s troubleshoot the software problem. Generally speaking, many computer brands, such as Dell, Lenovo, Sony, etc., equip their notebooks with power management software. If a certain "battery protection mode" is enabled, the power management software will prohibit battery charging and discharging after detecting that the user is using AC power to extend battery life. Therefore, if you find that your laptop is not charging, you can first enter the relevant power management software, turn off the battery protection mode or check the disable charging option. If there is no problem with the hardware, the battery can be charged.
