26. What is the FN key on the IBM keyboard?
It is a very powerful combination of function keys, such:
FN + F3: Turn off the LCD screen display, standby mode (standby), move the mouse or press any key to remove. Some machines
Type press FN + F3 cannot close the screen
FN + F4: enables the machine to be suspended. In suspend mode, all tasks are stopped and saved
In memory, all devices except the memory are stopped. Press the FN key for more than one second.
FN + F5: Search for Wireless Networks
FN + F7 switching shows the output status (LCD, external, or at the same time), which is a cyclic conversion process.
FN + F12: enables the machine to enter sleep state, Hibernate mode (sleep), all tasks are stopped, and the memory
And the current status is saved to the hard disk, and the system shuts down.
FN + pgup: enable or disable the keyboard light

Maintain the power-on status. When used again, press the FN key to wake up.

29. What is the difference between sleep status and suspension?
Suspension is a power-saving mode. The system stops external devices, such as hard disks and monitors, while the CPU and memory are still
However, work, wait for the user to wake up at any time, and then wake up the FN key on the keyboard several times.
Physical sleep is a more power-saving mode. It stores data in the memory in the hard disk so that the CPU stops working.
You need to press the shut-down key for the next usage, and the machine will be restored to the state when you perform sleep, instead of starting again w
Indows is a complex process.

30. What is the significance of adjusting the screen brightness?
There are three points:
It can protect users' eyesight. When the ambient light is dark, the light is brightened and the ambient light is dimmed.
The service life of liquid crystal can be longer, and the high brightness will shorten the service life.
It can make the machine more energy-saving, longer use time, high brightness will increase the use of power.
