System operation modes

Lenovo has preset several modes in which your computer can operate. The maximum attainable
performance, power consumption, and speed limit for the heat sink fan vary among the operation modes.
Consider the following conditions when you want to switch operation modes.
• The environment where you use your computer, and
• The tasks running on your computer
You can switch the operation mode in the pre-installed app Lenovo Vantage or Lenovo BaiYing. As a
shortcut, you can also use the key combination Fn + Q. Three modes are usually available for most Lenovo
computers. The following table lists the operation modes and the recommended conditions for each mode.
Note: The operation modes listed in the table are descriptive and may not be the same as those displayed
by the app.

Note: In Auto (Balanced) mode, the computer dynamically switches between High Performance mode and

Adjustable display refresh rate

Your eyes might not notice it but the content displayed on the computer screen refreshes constantly. Display
refresh rate refers to the number of times per second the screen content refreshes itself and is measured in
hertz (Hz).
A refresh rate of 60 Hz is adequate for most situations and is energy efficient. However, when viewing videos
or playing video games, a higher refresh rate usually provides a smoother viewing experience.
The displays of some Lenovo computers support dual refresh rates. For such a computer, you can manually
switch its display to work at either the higher or lower refresh rate. For Windows operation systems, the
manual settings are usually found in Settings ➙ System ➙ Display. As a shortcut, you can also use the key
combination Fn + R to switch the display refresh rate.
Note: Not all displays support dual refresh rates. If you cannot find settings to change the display refresh
rate, the refresh rate of the display might be fixed or cannot be manually changed.
