Two small questions about computers

1、"Standby" power management mode.

Standby mode is primarily used to save power, and it allows you to get back to work without having to restart your computer. Standby mode shuts down monitors, hard drives, fans, and other devices to keep the entire system in a low-energy state. When you reuse your computer, it quickly exits standby mode, and your desktop, including open documents and programs, returns exactly to the state it was in when it was waiting.

To get rid of the wait and get back to using your computer, move your mouse or press any key on your keyboard, or press the power button on your computer with a quick click.

Please note! Unlike the "hibernation mode" described below, standby mode does not store unsaved information on the hard disk, which is only stored in the computer's memory. This information will be lost if there is a sudden power outage during the period.

Therefore, you should save the file before putting your computer into standby mode. If you want to automatically save your work when you're away from your computer, you can use hibernation mode instead of standby mode. However, sleep mode will shut down the computer.

2.Hibernate power management mode.

When you use hibernate mode, you can turn off your computer and be confident that when you come back, all your work, including programs and documents that you haven't had time to save or close, will be completely and exactly back to the state you left off. The contents of the memory are saved on disk, and the monitor and hard disk are turned off, which also saves power and reduces the wear and tear of the computer. In general, it takes longer to get a computer out of sleep than it does for it to wait, but it consumes less power.

If you are constantly interrupted at work, such as some secretarial professions that often have to answer questions while doing computer processing**, etc., you can consider setting your computer to go into automatic sleep mode after a specified number of minutes. Sleep mode saves everything in memory to the hard drive, turns off the monitor and hard drive, and then shuts down the computer.

To resume computer operations, you can quickly press the power button on your computer, and all programs and documents that were open when you shut down your computer will be quickly restored to your desktop.

Usually, turning off your monitor or hard drive for a while can save power. If you want to leave the computer for a longer period of time, you should put the computer into standby mode, so that the whole system will be put into a low energy state; If you're away from your computer for a long time or overnight, you should put it to sleep.

Standby for less than two hours and dormancy for more than two hours
