I believe many people will encounter such a situation. In the middle of using the computer, they are suddenly called by a friend or need to go out for something. They don’t want to shut down the computer, and it would be troublesome to have to restart it when they come back. At this time, you will choose to hibernate the computer. Some people forget that the computer will automatically enter sleep mode. When I came back, I didn’t know why the computer screen was black and the power light was still on. So what is the difference between sleep and hibernation? How to wake up in both cases?

When the computer is idle, in addition to shutting down, the user can also Consider putting your computer into hibernation or sleep mode.

Compared with shutting down, the system has the following differences and advantages between hibernation and sleep:

1: There is no need to close the work in progress. After the computer wakes up, all open programs and windows will immediately Restore to the state before hibernation or sleep, allowing users to continue completing interrupted work.

　2: The wake-up speed is much faster than booting up. It takes about 40-50 seconds to turn on normally, while it only takes about 30 seconds to return to working state when sleeping, and it only takes about 5 seconds to return to working state when sleeping.

The reason why most people now start to download the win7 system is precisely because the system has many advantages and functions and is widely loved, and the hibernation and sleep functions are also commonly used in the win7 system.

Difference tips:

The system writes all the data in the memory to the hard disk during hibernation, and then shuts down all devices in the host of power supply. When waking up, the status data recorded in the hard disk is rewritten into the memory to restore the original working state. Therefore, after being in the hibernation state, even turning off the power will not cause any impact.

When the system is sleeping, the CPU is in a low energy consumption state, retaining the power supply of the memory to save the data in the memory, and at the same time cutting off the hard disk and display.Power supply for cards, network cards and other equipment to reduce power consumption. Since the CPU and memory are still powered during sleep, once the host is turned off or the battery of the laptop is removed, the sleep state is immediately interrupted and all unstored data will be lost.

How to wake up the computer from hibernation/sleep:

After entering the hibernation state, if you want to use the host again, you need to press the power button Start the computer.

When in sleep state, if you want to restore the original working state, just press any key on the keyboard or move the mouse to wake up the system.

If you are unable to wake up, you can try the following methods:

First, check whether the computer supports this function!

Check method: click "Start" - "Run"; then enter "CMD", then click OK!!

Second, enter "powercfg -a" in the command window, remember - there is a space in front; press "Enter" when finished "; The result shows Standby (S3); It means your machine supports the sleep function. If it is not supported, you need to contact the computer manufacturer to upgrade Blos.

Third, system setting solution:

Many times it is because this function is not turned on. First, right-click My Computer, then select Manage!

Fourth, then open "Device Manager" - "Mouse and other pointing devices". Then right-click and select Properties.

Fifth, then, switch to "Power Management" and then tick the box!!

We need to treat computer problems differently. The situations that may occur are similar, but the solutions may be different. Same. Sometimes the computer cannot be woken up after sleeping. Sometimes, the above method can be used to wake up the computer easily. Here, the editor still recommends that if you have something to do and don’t want to shut down, you should still turn on the computer. Sleep mode, this will be good for the circuit board, screen, and hardware. Okay, after listening to the editor's sharing, do you know the solution to sleep and hibernation?
