What is the difference between sleeping, hibernating, and turning off the hard disk, and will it be

Sleep is an energy-saving state. Sleep saves all open documents and programs, allowing your computer to quickly resume working at full power (usually within seconds) when you want to start working again. Putting the computer to sleep is like pausing the machine

The computer immediately stops what you're doing and is ready to start again when you want to get back to work. Dormancy is also an energy-saving state. However, sleep usually saves settings in memory and consumes a small amount of power, while sleep saves open documents and programs to the hard drive and then shuts down the computer.

Of all the energy-saving states used by Windows, hibernation uses the least amount of power. When your computer's battery is critically low, Windows automatically puts your mobile PC into hibernation mode. Turning off the hard disk is actually when no one has moved the machine for a long time, in order to prevent the hard disk from rotating for a long time, after turning off the hard disk, the hard disk will be in a "daze" state and stop rotating; When the computer is operated again, the hard disk will be reactivated; Of course, this function is mainly to prevent the hard disk from running without tasks for a long time and consuming the life of the hard disk; However, it should be noted that the hard disk will consume more when the hard disk is started and stopped, which is why the computer does not allow frequent restarts; Therefore, it is recommended to cancel the hard disk shutdown function when using the computer; This will extend the life of the hard drive; Turning off the hard disk has nothing to do with standby hibernation, as long as the machine is in a daze for a specified time, the hard disk will stop, and then the hard disk will start when you execute commands on the computer; Hibernation and shutting down the hard disk have a certain impact on the future use of the hard disk, and using these two often will cause the computer to read the hard disk too slowly.

If this problem often occurs when watching movies, it is due to the management of the power supply in the system, and the modification method is as follows: "Start" -- Settings -- Control Panel "-- Power Options" Power usage scheme setting "Always on" under the hard disk off, hibernation, monitor are all set to "Never".

Yes, the voltage will be disconnected when the voltage is low.

Dear, hello, I am glad to answer for you, how to turn off the hard disk hibernation of the computer Answer: The computer can turn off the hard disk hibernation by running the dos command window "powercfg h off" to name it, you can quickly turn off the system hibernation function. After restarting, the win10 system hibernation file will disappear from the system C drive, which can save a few GB of storage space, which is very practical for some users of small-capacity SSD hard disks.

1. First of all, you need to open the control panel and click on the power options: 2. After entering the power options, you need to select the power plan you are using and click to change the settings of the plan: 3. Then turn off the display and set the computer into sleep mode to never, and then click on the change advanced power settings below 4. The pop-up power options dialog box, the group is setting the sleep time of the hard disk to 9995, and finally the sleep settings will be all the settings in the options, set to never, Click OK to save.

Sleep means that the system goes into standby, and the hard disk and CPU are still working; Hibernating hard disks, CPUs stop working, and the power consumption of the machine is close to shutting down; And what you said about turning off the hard disk should belong to a kind of hybrid sleep, between sleep and hibernation, its function is to make the hard disk stop working, but the CPU is still working, and it is also very low power consumption.

This is most likely the cause of the drive, as earlier drives had a problem where when it was woken up from hibernation, the drive motor needed to be restarted, and the drive motor would crash when it could not withstand the current shock. Because the drive head may not have returned to the drive landing zone, rebooting the drive may corrupt the CMOS information and drive data, ranging from the main boot area information to disk track 0.

Therefore, it is recommended that you first use IDE HDD Auto Detection in the BIOS to identify the LBA mode of the hard drive, and then save and exit. If that doesn't work, use a floppy disk.

Boot the system and use the "fdisk mbr" command to restore the main boot area. If that still doesn't work, you can only use fdisk to repartition the hard drive, then format it, and reinstall the system and software. The only serious thing is to perform a low-level format on the hard drive.

Finish. Note that once the hard drive is back to normal operation, the hibernation feature should be disabled in the system settings.

If you need to take other tests, you can try the following options in the Power Management Setup in the BIOS

1.Prohibit hibernation features: Set Power Management to disabled. The following options will not work. No more testing it.

2.Disable Advanced Power Management: Setting PM Control by APM to Disabled Advanced Power Management can cause a lot of problems and can be used as a diagnostic switch for abnormal computer hibernation and shutdown.

3.Set HDD Power Down to "Disabled", which disables hard drive energy saving. Because some hard drives will be abnormal when they run again after saving energy.

4.Set primary IDE 0 and primary IDE 1 to enabled; Setting Secondary IDE 0 and Secondary IDE 1 to Enabled will cancel the current hibernation state of the computer or IDE device when the corresponding IDE channel device has access actions (such as reading and writing to a hard disk or optical drive). If they are set to disabled, they will continue to hibernate regardless of the access requirements of the hard disk or optical drive.

5.Set the PME Event Wakeup to Enabled.

Turning off the hard disk means that when the system is idle, the hard disk is not running, sleep is the standby to save the data that is currently in the running state in the memory, the machine only supplies power to the memory, and the hard disk, screen and CPU and other components stop supplying power. Since the data is stored in fast memory, it is faster to enter the waiting state and wake up. However, this data is stored in memory, which can be lost if the power is lost.

Hibernation is the process of writing data from memory to the hard disk, at which point you can cut off the power to the computer, which is similar to shutting down. If you want to continue, don't use sleep, sleep, you just need to choose how many minutes to turn off the monitor, the monitor is a big power consumer. Even if you set the hard disk to turn off after a few minutes, the setting is invalid when you are in **.

Sleep: The system will cut off the power supply to all other devices, but the power supply to the memory will still be there, and the memory data will not be lost.

Hibernation: The system will save the contents of the memory to a file in the root directory of the system drive, and then completely cut off the power to the computer. It is recommended that the computer be turned on for a while, and it will automatically turn off the monitor!
