With the popularity of laptops, most users have experience in using laptops to handle personal affairs in their own lives. The most prominent feature of a laptop is its mobile feature, even if there is no external power supply, we can continue to use the notebook for a period of time to deal with various situations through the battery. At the same time, the problem of the endurance of mobile devices will also emerge. Is it possible for us to extend the use time of our Win7 notebook through some tips to improve our use performance?

By simultaneously pressing Fn and a button indicating brightness changes, you can adjust the brightness, generally, this brightness is indicated by an up arrow or down arrow in a small sun. Different brands may change.
Next let's talk about wireless network cards. Some users are used to enable wireless network cards all the year round. When using batteries, they may not have available Wi-Fi signals in their environments, at this time, it is not suitable to enable the wireless network card. So how to disable it? In the above mentioned Win + x mobile center, you can choose to enable or disable wireless connection:
 
Most laptops have a switch to enable the wireless function quickly. Different brands may change. Finally, the most important power option is that we can customize our own power plan through this item in Win7 to achieve the best power-saving effect. Still use the Win logo key + x to open the mobile center. Here we can not only quickly turn on the power option, but also adjust the preset Power Plan:

The following describes these options. Hard Disk: after the set time, the hard disk enters the low power state.
 
Desktop background setting: The Windows 7 desktop is set to a slide group. If you choose to suspend the desktop, the desktop background will not be switched.
 
Wireless Adapter: Nic Performance Settings.
 
Sleep: After a computer is idle for a period of time, it enters sleep state. Sleep State means that when a user wants to start working again, the computer can quickly resume full-power work. Putting a computer into sleep is like pausing a DVD producer: the computer immediately stops working and is ready to continue working.
 
Hybrid sleep: the system will recover from the memory if it is powered on. If it is powered off, it will recover from the hard disk, so you don't have to worry about data loss.
 
Sleep: saves work and settings in the memory and consumes a small amount of power, while sleep saves open documents and programs to the hard disk, and then closes the computer.
 
USB: enables a USB device to sleep for a certain period of time.
 
Power Button and lid: Set the corresponding action for the notebook cap, power button, and sleep button operation.
PCI Express: configures power management for devices that belong to the PCIE bus, such as hard disks, NICS, sound cards, and video cards.
