The laptop keeps showing 0% when it cannot be charged, and it immediately shuts down after unplugging the charger

Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.12
When using a computer, sometimes we encounter situations where even if a charger is plugged in, the charging speed cannot keep up with our usage speed, resulting in an automatic shutdown during the charging process. When we unplugged the charger, it immediately shut down due to the lack of external power support.



The reasons for this phenomenon can be explained as follows:

Firstly, the power of the charger is insufficient. Each laptop has a minimum operating power requirement, and when using a charger with higher loads (such as running large programs or performing complex calculations) and connected to a low-power (such as a regular household socket), it may not provide enough energy to maintain system operation and fast charging simultaneously.

Secondly, there is an issue with operating system settings. Some operating systems may choose to remain on by default and not actively adjust device status or close applications based on the current power supply situation. Therefore, after connecting the charger, it remains on and runs normally.

To solve this problem, you can try the following methods:

Firstly, please ensure that you use an original or certified brand adapter/charger that meets the specifications and has sufficient power output;

Secondly, it is recommended that you check the power management options in the system settings after plugging in the adapter. Some operating systems provide settings that can automatically adjust the device status based on the connection and disconnection of the charger to extend battery life or improve charging speed;

Finally, when performing high load operations, it is recommended that you connect your laptop to a more powerful socket or use an adapter that includes USB-PD (Power Delivery) functionality to ensure sufficient power supply.

In short, when using a laptop, it is important to pay attention to the power of the charger and system settings, and choose appropriate measures to solve possible shutdown situations.
