Preface

Perhaps many friends who use laptops will encounter a very headache, that is, after the laptop is turned off for a period of time (within a week or several hours), the battery consumption is very high. So what exactly causes the laptop to consume fast power after shutting down? How to solve the problem of fast power consumption? The following is a detailed description of the problem points and their solutions.

Several problem points

Network wake-up

Network wake-up function is a function of the network card to wake up the computer through the network. This function requires the network card to remain powered on. Generally, you can see on the connected router and other devices that are connected to the network port in the connection state, and generally display a 10Mbps rate. At this time, the power consumption of the laptop is relatively large.

USB charging

usb charging function is also a feature of laptop . It is that when the laptop is turned off, it can still use the corresponding USB port to power the connected device. If the USB charging port of the laptop has a connected device, the laptop battery is also in a power consumption state.

Quick Start

Quick Start is a new technology of windows10. It can quickly start the system from memory when the system is powered off after the system is powered off. It does not take more than ten seconds of waiting time, and the running state of some applications can also be restored. However, this technology relies on the continuous refresh of memory data, that is, it is necessary to keep the computer's memory constantly powered to achieve rapid startup normally. Therefore, if this function is enabled, it will also cost a lot of battery power.

Solution

and above are several major problems with serious power consumption after shutting down the laptop. So below will explain how to solve the power consumption problem.

Turn off the network wake-up

The network wake-up function can be turned off. There are many tutorials on the Internet, so I won't explain in detail here.

Close Quick Start

Quick Start function can also be turned off. There are many tutorials online, so I will not explain in detail.

Disconnect the USB peripheral

, that is, after turning off the laptop, you can unplug the device with the corresponding USB interface.

Unplug the charger before shutting down

This method is effective in testing and can easily solve most of the system power consumption problems caused by the settings. The principle is that after the laptop unplug the charger when the boot state, the computer will automatically enter the battery power supply mode. The default power mode of the Windows system is different from the power consumption settings of the battery power supply and the charger power supply. Some settings that continuously consume power are turned off, so the power consumption will be reduced accordingly after shutdown.

Summary

Comprehensive the above, the easiest and most effective solution for laptop power consumption is to unplug the charger before shutting down the laptop, and unplug all USB socket devices after shutting down. Of course, this method is only the simplest and most effective method, and it does not ensure that the system does not consume power at all. Different power consumption problems still have to be solved by different methods.
