Many friends have seen an icon called "Energy Management" in the notification bar in the lower right corner of their laptops, but they don't quite understand what it is used for.
In fact, this is a very practical tool that comes with Lenovo notebooks. Power management software .
Using software and hardware to cooperate with each other, it intelligently adjusts the performance and power consumption of various computer components, which can effectively extend the battery life and enhance the notebook's battery life.
Today, we choose the Win8 system as an example to teach many audiences step by step, link by link, and in detail how to use this software with specific practicality and functionality.
Step 1: Download the appropriate power management software from the official website
The first step to use Energy Management is to make sure that your laptop has this software installed.
The safest and most reliable way is to remove the brand of your laptop Official website .
Open the "Driver Download" page of the official website and find the "Host Number" input box.
This number usually starts with letters such as NS, NA, ES, SS, FS, EA, BA, etc., followed by an 8-digit number. You can find it on the sticker at the bottom of the notebook.
After entering the number, the website will pinpoint your model.
Then, for the operating system type, select Windows 8 (if it is Win8.1, select the corresponding one).
Find the "Power Management" category in the driver list and click to download the corresponding software.
Pay special attention to the fact that the power management software in some notebooks contains shortcut key drivers.
If the multi-function button on your laptop fails to work, or you cannot use the Fn key combination to turn on WiFi, it is most likely because the driver is not installed.
Simply install the power management software to solve the problem.
Step 2: Install and set up auto-start at boot
After the download is complete, double-click the installation file and follow the prompts to complete the installation.
After installation is complete, it is strongly recommended that you Restart laptop .
After turning it on again, you will find a green battery icon in the notification bar in the lower right corner of the screen, and that is the Energy Management program icon.
If you don't see it, you can click the small inverted triangle on the left side of the notification bar, select "Customize", find "Energy Management", and set it to "Show icons and notifications".
After setting up in this way, the software will start with the system and work silently in the background.
At any time, you can right-click the icon to quickly switch between different power modes, which is extremely convenient.
Step Three: Understand the Four Core Power Modes
Right-click the Energy Management icon in the notification bar, and a menu will pop up. There are generally four power modes in this menu.
While different laptops may display slightly different options, the core functionality remains the same.
The first one is " Balanced performance "model.
This is the most commonly used mode. When the power is plugged in, the CPU's cooling method is active, and the processor's performance will be dynamically adjusted from 5% to 100%.
To put it simply, the computer will automatically turn on the power-saving mode when it is idle, and will output at full capacity when it is busy, thus taking into account both performance and energy consumption.
The second mode is the "high performance" mode. If you choose it when playing games or running large software, it is the most appropriate situation. In this case, the CPU and graphics card will exert their maximum performance, and the heat dissipation will also be adjusted to active mode, so as to ensure smooth and unobstructed operation.
The third one is " Super energy saving ” (or energy-saving mode).
In this mode, the CPU frequency will be limited in order to maximize battery life.
Just like a CPU that originally had 2.5GHz, after it is turned on, it may not even be able to break through 1GHz.
Therefore, only when the battery is used for power supply, the recommendation to turn it on will be made. If you use this specific mode while plugged in, you will notice that the computer's operation status gradually becomes sluggish, and finally it will appear like this.
The mode ranked fourth is the "Energy Star" mode. It is a mode given by Lenovo personally. This mode feels very similar to performance balance. It can be understood as a balanced plan formed after Lenovo's official optimization.
Step 4: Enter the power management center and maintain the battery
After double-clicking, the Energy Management icon in the notification bar is operated to enter the main interface of the software, which is the "Power Management Center".
The core function here is about battery maintenance.
You'll see two key options: "Maximum battery life" and "Best battery care."
When the "Maximum battery life" option is selected, once the laptop is plugged in, the battery will be charged at any time until the battery reaches 100%.
Moreover, when the "Best Battery Care" mode is selected, the system will automatically limit the battery power to a range between 45% and 50%.
Doing this can greatly slow down the loss of battery cells and effectively extend the battery life.
Many friends ask, should I unplug the battery when plugging in the external power supply?
In fact, there is no need to pull it out at all.
You only need to turn on the mode called "Best Battery Care", so that you can continue to use it with peace of mind by keeping it plugged in. This will not only protect the battery, but also avoid damage to the computer caused by unexpected power outages.
After reading the above tutorial, you must have a comprehensive understanding of this laptop battery maintenance software called Energy Management.
To summarize briefly: Go to the official website to download and install, set up the startup properly, and flexibly switch power modes according to usage scenarios (such as playing games, working, relying solely on battery power). If you often use the computer with the power supply connected, remember to turn on "Best Battery Care" to protect the battery.
I hope this content can help you make better use of your notebook.
