Why doesn t the notebook have a sleep option when the lid is closed ? How do I set it to sleep when

From the start menu, find the "Accessories" command prompt, manually enter the following command: powercfg -a, from here you can clearly see that the computer supports hibernation, displaying "Hibernation not enabled"。Still in the command prompt, start the sleep method:

Manually type the following command:

The powercfg -hibernate on command can take effect immediately after it is executed, and there is no need to restart the system, execute the "powercfg -a" command again, which will prompt that the current system has supported hibernation and hybrid sleep.

Open the Control Panel.

Power Options – Select Power Plan – Balance Energy Saving High Performance – Change Plan Settings – Change Advanced Power Settings – Sleep – Allow Mixed Sleep – Change to "Off". Save to exit.

Then you can see that there is an extra "hibernation" button. Ha ha.

Because hybrid sleep is originally enabled, the so-called hybrid sleep is a combination of standby and hibernation. If your computer doesn't power on after a mixed sleep, it's actually standby; If the power is cut off, it is essentially dormant. When you turn off Hybrid Sleep, that sleep button is true standby, i.e. it still maintains power to memory; And the sleep mode, where even the memory is powered off, comes out.

Now the system is turning off the hibernation option by default, which not only occupies hard disk space, but also bad hard disk, and needs to be turned on in the system properties setting.

<> click [Other Power Sources to Disassemble].

Click [Select the function of the power button].

It can be set to perform the action when the power button is pressed or the lid is closed when the battery is used or the power is turned on (no action, inch-hidden date sleep, hibernation, shutdown, etc.).

After the settings are complete, click [Save Changes] to apply to all power plans.

1. The reason why the laptop does not sleep when the lid is closed is because the power option is not set.

2. We can open the control panel on the computer.

Click "Category", select the big icon, select "Power Options", in the power options, click "Select the function of closing the lid", set the battery and leakage Wang Tong power supply when closing the lid to "do not pick up any operation", and finally after the setting is completed, click "Save Modification".

The reason why you can't sleep when you close the lid of the laptop is that your computer system is streamlined, and many streamlined systems such as WinXP and Win7 systems have streamlined the sleep function, which is turned off by default when installing the system, and you need to turn it on before you can use it. The way to turn it on is: Start --All Programs --Accessories--Run, type powercfg -hibernate on.

Click the "Start" button in the lower left corner of the computer, as shown in the figure below;

Find the "All Programs" menu to crack the brigade, open the "Accessories" menu, and click "Run";

In the "Run" command bar, enter powercfg -hibernate on and click OK.

Find the "Control Panel" menu in the Start menu, click, or find "Computer" on the desktop, and right-click to find "Control Panel;

Find "Power Options" and click to turn it on;

6.Select Close the lid as the Sleep action, and then save the modifications.

Computer hibernation refers to the fact that the data currently in the running state is saved in the hard disk, and the power supply of the whole machine will be completely stopped. You can completely disconnect the power of the computer during sleep, and automatically turn off the monitor and hard disk for as long as you need.

The setting of the notebook with the lid closed and not sleeping is as follows:

Tool Raw materials: Tsinghua Tongfang, win7 system.

1. Click the start button in the lower left corner of the notebook, and then click "Control Distress Panel".

2. Then on the control panel page, click "Hardware & Sound";

3. In the hardware and sound interface, click "Power Options";

4. In the power options interface, click "Select the function to close the lid";

5. When closing the lid, under the battery, click "Sleep" and select "Do not take any operation on the crack core";

6. Finally, under the power supply, click "Sleep" and select "Don't take any action", you can set the laptop to close and not sleep.

In the "Power Settings", set the option after closing the lid and the posture of the box: Book shouting.

First, the subject is different.

1. Sleep: It is a new energy-saving mode for the computer to change from the working state to the waiting state.

2. Hibernation: Save the data that is currently in the running state in the hard disk, and the power supply of the whole machine will be completely stopped.

Second, the characteristics are different.

1. Sleep: When the sleep state is turned on, all the work of the system will be saved in a system file under the hard disk, and the power supply of all devices except the memory will be turned off at the same time.

2. Hibernation: The power of the computer can be completely disconnected during hibernation, and the time for automatically turning off the monitor and hard disk can be set.

Third, the status is different.

1. Sleep: After the system switches to sleep, the system will store the data in memory, and then turn off the power supply of all devices except the memory, so that the data in the memory is still maintained.

2. Hibernation: The operating system began to introduce advanced power management, which is to turn off some devices when the computer is idle and put the computer into a state of waiting for rest.

"Sleep" is an energy-saving state that allows your computer to quickly resume working at full power (usually within seconds) when you want to start working again. Putting your computer to sleep is like pausing *** Announcer: it immediately stops the current operation and is ready to restart when you want to continue working.

Hibernation is a power-saving state designed primarily for laptops. Sleep usually saves work and 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.

For laptops, if you know that you will not use it for a long time and it is not possible to charge the battery during that time, you should use the sleep mode. "Hybrid sleep" is primarily designed for desktop computers. Hybrid sleep is a combination of sleep and hibernation - it saves all open documents and programs to memory and hard disk, and then puts the computer into a low-energy state so that you can get back to work quickly.

This way, in the event of a power failure, Windows can resume your work from the hard drive. If you turn on Hybrid Sleep, you put your computer to sleep and your computer automatically goes into Hybrid Sleep. On desktop computers, Hybrid Sleep is usually turned on by default.
