What are the learning of computer standby and hibernation?

The various parts of the computer system are learned. In many people's view, standby and hibernation are a simple operation, but many people on standby and hibernation still can't figure out the relationship and difference between them. Today Just pass the form of the problem and think about popularizing it.

Q: Is there any benefit to standby and hibernation, but also to shut down? Or is it better to change hibernation directly to shutdown?

A: Although the advantages of standby and hibernation are obvious. However, ACPI/APM is required for both hardware and system. If the hardware or system is not supported, the standby and hibernation functions are forcibly used. It is easy to lose data, the system is unstable or even crashes. At the same time, only in the case of a real shutdown. Only hardware changes can be made, such as replacing devices, adding memory upgrades, etc., so they are not a substitute for shutdown.

Q: I accidentally lost it in <;start →shutdown”&###################################################################################### The problem can be solved by reinstalling the motherboard driver, or by deleting the hardware that supports “ACPI” in the Device Manager, and then restarting the machine and reinstalling the hardware according to the system prompts. If you cannot stand and hibernate on a newly installed system, or the system fails to start after performing these functions, first confirm in BOIS that STD and STR have been turned on. If it is already open, confirm whether the hardware supports ACPI (especially the motherboard). ), or consider the issue of hardware conflicts.

Q: I am using Windows XP. In the screen saver window, I have selected "Use password protection when recovering", but the strange thing is that it does not work. After the screen saver starts, the keyboard or mouse will end the screen saver, and there is no window for entering the password!

A: Under Windows XP, only “Use password protection during recovery” It doesn't work. Right-click on the desktop to open “Properties", in the Power Options Properties window, select “Advanced>, check “ When the computer resumes from standby, prompt for the password ”. In addition, the screen saver password of Windows XP is different from that of Windows 9x. The password cannot be set separately. It can only be opened by the user password when the system logs in.

Q: Sometimes my computer has been used for a long time, I want to take a break, then I choose to let the computer sleep, but the computer often does not respond at all?

A: Sleep Is to save the data in the memory to the hard disk, because the computer runs for a long time, and some of the infrequently running data is saved to the virtual memory, then select sleep and some of the data in the virtual memory is not released in time, There will be no reaction after performing sleep. In this case, it is recommended to restart the computer.

Q: Why do I enter the “Power Options & Rarr” option after the desktop, “Enable Hibernate Support” checkbox is grayed out and not selectable?

A: Current System Disk The remaining space is smaller than the memory space, and all the contents of the memory are saved to the hard disk during hibernation, so the remaining space of the hard disk is greater than or equal to the capacity of the memory. Clean up the disk and make enough space in the system disk.
