Windows 7 does not wake up from standby mode. How to wake up from sleep mode if Windows won't wake up from it
Computer sleep mode, which is also relevant for Windows 7, is an excellent invention for those who actively and daily use such technology, but do not want to greatly increase energy costs. In this case, the screen of a PC that is not in use for some time turns off, and the computer switches to energy saving for a while, and if it is necessary to use the computer device again, Windows 7 itself wakes up from sleep mode. The most important thing is that the current session is completely saved, with all the tabs and programs open by the user, which can then be used again, but to ensure this result it will be important to know how to wake up from Windows 7 sleep mode.
The method for waking up a particular computer from sleep mode depends on many factors and settings, primarily on the settings specified by the manufacturer, the specific type and model of the device, because each case may have its own nuances. For example, methods suitable for laptops are sometimes not suitable for desktop PCs, and vice versa, but there are also some virtually universal methods that turn out to be relevant for a great variety of gadgets of a similar variety. So, often, in order to put a “asleep” computer back into an active state while preserving the tabs previously used during the current work session, pressing certain buttons is required.
Moreover, in most cases, to wake up from sleep mode, you need to lightly press the power key, indicated by a circle partially crossed out by a small dot, and this method works with many desktop computers and laptops. For the latter, the list of keyboard buttons required to return the device to the “wake” state may be a little wider - in some cases you will have to press, for example, Fn, although for some laptops everything is even simpler. A number of models of laptop computers have such settings that they can be exited from sleep mode by pressing almost any key on the keyboard or even the mouse, which will give the system a signal to resume the current work session.
By the way, with laptops running Windows 7, sometimes the usual way of lifting the flap on which the monitor is located above the keyboard and moving it to a virtually vertical position also works. This method is especially relevant in cases where the laptop PC was switched into a “sleepy” state by folding it, i.e. connecting the sashes in a horizontal position, respectively, the reverse action and effect should have a corresponding effect. However, sometimes it happens that, despite performing any of the above actions, the computer or laptop does not wake up from sleep mode - Windows 7 does not work properly to allow such a transfer.
In a situation of this kind, the most important thing is to try to find the reason why the system settings do not work, and the first thing that requires especially close attention in this regard is the condition of the battery, however, this moment is relevant only for laptop computers equipped with a battery. If it was not properly charged before entering sleep mode, then it is possible that, even while in sleep mode, the device will gradually discharge, which is why it will stop responding to pressing any buttons. Therefore, if you have problems getting the laptop into an active state, it is advisable to first connect it via a suitable power cord to the mains to recharge a possibly discharged battery.
It is advisable to start repeated attempts to transfer a laptop PC from sleep mode to active mode not immediately after connecting this gadget to the power supply, but wait at least ten minutes so that the battery has a small reserve of charge. This should be enough to start the system, which you should try to do by pressing any of the above keys: power, Fn or another, which, when pressed, activates the computer. By the way, even for stationary PCs, lack of power supply can sometimes become an obstacle to waking up from sleep mode: there may be a power outage or the power cord may be damaged.
In the case where the issue is not at all a matter of electricity, it is possible that the problem with waking the computer from sleep mode lies in a system failure that occurred while it was in this state or a violation of some settings. To eliminate such problems, the restart button is useful: for stationary PCs it is usually located on the system unit next to the power key, and for laptops it is on the bottom; pressing it allows you to restart the system while maintaining the current session. If, for some reason, it is not possible to independently resolve the difficulties with waking up your computer from sleep mode, it is not a sin to turn to a qualified technician for this.
A possible reason for this behavior of a computer or laptop with Windows 7 installed is the programmed shutdown of the hard drive from power after a certain time of operation.
The Windows7 system is configured by default in such a way that the hard drive is turned off after 20 minutes from the start of operation in standby mode. When you try to turn it on again, problems may occur. To avoid such problems, it makes sense to disable the drive power-cut feature.
To do this you need to do the following:
1. From the Start button menu, select the Control Panel folder. In the Control Panel window, go to the "System and Security" section. In this section, select the "Power Options" tab.
2. In the Power Options section, select the Change Battery Power Settings tab. The Select Power Plan window opens. Here the “Balanced” plan is selected by default, leave it that way. Go to the "Power plan settings" tab of the balanced plan.
3. In the window that opens, go to the "Change advanced power settings" tab. Select the line “hard drive” in the drop-down list, then “disconnect the hard drive through”. Left-click on the set time value in minutes and in the window that opens, select “Never”. Click OK.
After this change in settings, the hard drive will no longer be disconnected from the power supply, which will speed up the time the computer wakes from sleep mode.

Sometimes when working with a computer it is required that it remain on for quite a long time, but at the same time the computer can be in a passive state. mode. In order not to waste extra electricity and reduce the computer's power consumption by reducing the processor power, you can run the expectations or computer sleep mode. In Windows Me or Windows XP, you can do this at any time.
Instructions
First, open the Display Settings and check if your computer supports standby mode and adjust the idle power settings. Both in a regular desktop and in a portable one, you can switch it to mode by clicking the “Start” menu and then clicking on the “Shut down” button. A window will open in which, from all the buttons that appear, you need to select the “Sleep Mode” button. Click OK for the computer to enter expectations.
Open the “Power Options” section and in the properties in the window that opens, select the “Advanced” tab. Set the properties so that when you click the button once, it goes to . Click Apply and then Ok. Press the Power button to make sure the changes take effect.
If you use, switching to sleep mode will become even easier for you - most have this mode when lowering the lid of the computer while it is on. If your computer does not have these settings, open the Start menu, go to Control Panel and go to the Power Options section again.

Setting up the computer's power subsystem and operating system, in which current data is saved to a special file on the hard drive, is called hibernation regime. It is very convenient to restore a fully operational state of the computer and running programs by “waking”, that is, exiting sleep mode. This takes much less time than booting from a powered state
Instructions
Open My Computer and check the free space on your system drive. Typically, the C: drive is used as the system drive. Right-click on the disk icon and select the "Properties" menu item. On the “General” tab, you will see a diagram of disk space usage, next to which information about free and used space will be indicated. Hibernation typically requires at least 3 gigabytes of unallocated disk space. Delete or move unnecessary files and check again. As a result, you will have space for the hibernation service file or the “Sleep” mode.
Click the "Start" button and launch the command execution menu - the "Run" item. Type the command to call the system console cmd and click OK. A command prompt text window will open. Type the command powercfg -h on, this will create a file on your hard drive where Windows will save data about the current state of the computer, for example, your open files and programs. This file will have a volume equal to the amount of RAM on the computer. Close the console window after running the command.
Open the Start menu again and select Run. Enter the command powercfg.cpl in the line - this will open the menu for configuring the computer’s power settings. Another way: open the control panel, launch the “Power Options” menu. In both cases, you will see a window with settings for turning off the monitor and using options for reduced power consumption.
Click the "Set up a power plan" link. There will be several of them in the window. Choose the one that is opposite the current nutrition plan marked with a black dot. A window will open in which you need to click on the “Change advanced settings” link. A list of settings items will appear, in which find the words “Sleep” and click on the “plus” icon next to it.
Expand the “Sleep After” submenu and select the time in minutes that suits you. Expand the “Allow hybrid sleep” option and disable it. Also select the "Disabled" option in the "Allow Wake Timers" menu. Click the Apply button and agree that you need to restart your computer first.
Repeat these steps for all the energy plans you use. For example, for laptops, it makes sense to set the power plan to Economy. Be sure to restart your computer. After this, sleep mode will appear in the shutdown menu.
Create a shortcut for sleep mode. Sometimes running Disk Cleanup will cause the Sleep option to disappear from the menu. To restore sleep mode and enable it regardless of the presence of the icon in the shutdown menu, you can use the following method.
Click the “Start” button and type the following text in the “Search programs and files” line: “shutdown -h”. At the top of the menu you will see a line with this command. Right-click on the found file and select the “Send…” menu, “Desktop” item. Clicking this icon on your desktop will initiate sleep mode.
Sometimes users of Windows operating systems are faced with the inability to boot into the desktop after resuming from sleep. regime. Most often, this problem is associated with old versions of video drivers, but in some cases you have to look for the real cause.
You will need
- Windows operating system with the “Hibernation” option activated.
Instructions
When emerging from sleep regime the user is usually faced with three options: the desktop is displayed correctly, a BSOD (blue screen of death) appears, or the absence of any image, i.e. black screen. The last two conditions are not critical and can be treated with a small add-on to the system.
If you have already encountered such a problem, restarting your computer will help you: press the Reset button on the front panel of the system unit. After the system boots, you should configure one of the USB devices, a mouse or keyboard. To do this, open the “Device Manager” applet by selecting the item of the same name in the “My Computer” context menu. You can also do this through “Run”, which is located in the “Start” menu. In the window that opens, enter the command devmgmt. msc and click OK.
In a new window, expand one of the “Keyboards” or “Mice and other pointing devices” sections. Call the “Properties” of the device through the context menu. Then go to the Power Management tab. Uncheck the box that says “Allow this device to wake the computer from sleep.” regime» and click OK to close the window.
In some cases, it is recommended to completely disable Standby/Hibernate modes. You can perform this operation by configuring the “Properties: Screen” applet, but this does not always help. Therefore, you need to launch a special application through the Run tool. Press the Win + R key combination, enter the command powercfg.cpl and click OK.
In the left column, select the line “Set sleep mode.” The “Put the computer to sleep” and “Turn off the display” options must be set to “Never”.
Waiting and sleeping mode computers running Windows OS are designed to reduce the device's energy consumption and preserve user data during interruptions or power outages.
Instructions
Make sure you understand the difference between these two functions: Waiting mode switches the computer to mode minimal energy consumption, but does not turn off the computer. Therefore, when going to standby mode It is necessary to save all changes made, otherwise they will be lost if the power goes out.Sleeping mode Shuts down the computer while maintaining the existing state on the hard drive. Therefore, saving the changes made is not necessary.
Waiting mode The computer is turned on by default and is available to the user in the shutdown and shutdown menu, being one of three options: - reboot; - shutdown; - standby mode A.
If on computer sleep was previously enabled mode, then to turn on the standby mode You will need to call up the desktop context menu by right-clicking on an empty space. Select the “Properties” item and select the “Screen Saver” tab in the dialog box that opens. Click the "Power" button in the "Energy Saving" section at the bottom of the window and go to the "Sleep" tab mode» next dialog box. Uncheck the box next to "Allow sleeper" mode a" group "Sleeping" mode" and confirm saving the changes made by clicking the "Apply" button.
Select the “Advanced” tab and select the “Go to standby” option mode" in the drop-down list of the line "When you press the button to go to sleep mode" section "Power buttons". Confirm the selected action by clicking the “Apply” button.
This can happen to anyone: the user’s computer goes into standby mode, and after some time, when waking up, it does not exit it, showing a black screen or BSOD - blue screen of death. The problem is not that common, but it does occur. What’s worse is that it’s not possible to cope with it in all cases, but we’ll still try to do it.
Update your video card driver
The first and one of the simplest solutions that can help is. I will not describe this process, since I talked about it in detail in the next article.
The main thing is to be sure to perform this easy operation, which can easily solve your problem.
Prevent your mouse or keyboard from waking up from sleep mode
In this case, the problem may be due to the fact that when waking up from sleep mode, some USB devices do not support this very mode incorrectly, resulting in an error. Therefore, you need to disable one of these devices. Please note that you cannot turn off both devices at the same time, since in this case you will not be able to wake the computer from sleep mode at all. Therefore, first turn off, for example, the keyboard and, if that is not the problem, turn off the mouse, and at the same time do not forget to turn on the keyboard.
This is how it is done. (for example, press WIN+R and in the Run window enter the word devmgmt.msc, then click OK). Here select a device, for example a mouse. Right-click on the device and select Properties.
Prevent the hard drive from being disconnected
Here we will look at turning off the power supply to the hard drive when entering standby mode. To do this, go to the control panel and select “Power Options”. In the new window, select the current power plan setting.
Then click "Change advanced power settings."
In the additional parameters window, in the “Hard disk” subsection, in the “Turn off hard disk through” item, set the value to 0 and click OK.
This must be done if there are problems with the hard drive when exiting standby mode.
What else?
- The problem may be related to the hard drive itself, or rather, to its performance. The hard drive should be checked using a special utility.
- Experts often recommend updating the BIOS version to the latest. And this method helps.
- For Windows 7 you can try.
- On some video cards, according to Internet users, the problem cannot be cured. The only solution is to replace the video card itself. Of course, in this case it is much easier to refuse to use standby mode altogether.
People are often interested in what sleep mode is, how it is useful, and how to put a computer/laptop to sleep. There are also a lot of questions about why the computer wakes up from sleep mode on its own. There are many answers on this topic, but they are often written by incompetent individuals, resulting in confusion. In this article we will try to answer all questions regarding this option, as well as resolve the issue of waking up the computer independently. So let's get started.
What is hibernation mode?
There is some confusion with the modes. It arose due to the fact that there are two of them, and not everyone understands how they differ. Let's figure out what each of them is and establish what is their difference.
- Waiting mode. We are used to seeing it under this name in Windows XP. In the seven it was called “sleep mode”. That's why people get confused, mistaking him for sleeping. How does he work? The computer or laptop, it doesn’t matter so much, goes on hold. All programs that were currently open are stored in RAM, which continues to work. Therefore, if you hear somewhere that equipment does not consume electricity in standby or sleep mode, it is a myth. This is a volatile mode that is not very reliable. After all, if you stop the supply of electricity, the computer will turn off. Accordingly, all data that you worked with before the computer was sent to standby will be lost.
- Sleep mode. In XP it continues to exist under this name, but in Windows 7 Microsoft once again decided to show their unbridled imagination by renaming it, which completely confused novice users. Here it is called hibernation. How is he different from someone who is waiting?
Unlike waiting during hibernation, all data from RAM is written to the hard drive in a file calledFiberfil. sys . This is a special file that is created by the system to store data in sleep mode. When the computer is awakened, all data from it is returned to RAM in the same form as it was before hibernation.
We've sorted out the general description. Now you know how they work and how they differ. Now let's pay more attention to sleep mode in Windows XP and 7 systems, since the settings are slightly different in each of them. We will also consider the issue of independently exiting standby/hibernation mode and find out how to fix it.
Windows XP
Setting Sleep Mode
- Inclusion. In this system, sleep mode is initially disabled for some reason. It's easy to turn it on. To do this, do one of the following:
- Open control Panel, Power Options and go to the Sleep tab. Next, check the box "allow sleep mode" and save the changed settings.
- Click on an empty space on your desktop and select Properties. Next, go to the screensaver tab, open the power item. Next, perform the same steps as in the previous method.
- Setup. Depending on what kind of technology you use, a computer or laptop, entering sleep mode can be done in different ways.
- For a computer, you can use the corresponding key on the keyboard, as well as the power button. The transition to sleep mode is configured as follows: "control Panel", "power supply", tab "additionally". Next, select an action for the power button and sleep mode from the list. I would like to draw the attention of Windows XP users that in some cases the sleep button, even if it is on the keyboard, is not displayed in these settings. For it to appear, you must press this key for the system to identify it. By default, it puts the computer into standby mode.
- For laptops, there are 3 ways to enter sleep mode: by pressing the power button “if it is pre-configured”, by using the combination FN + a certain key and after closing the lid. Actions for all of the above methods in laptops can also be configured in the power supply on the Advanced tab.
Why does my computer/laptop wake up from sleep mode on its own?
There are few such reasons in Windows XP and they are not something out of the ordinary.
- The most common "strange" wakeup call for computers is touching the keyboard or mouse. In fact, there is nothing supernatural here. It’s just that most modern computers react to keypresses and regard them as a signal to wake up from sleep. How to solve this problem? If you send your car to sleep, it means you don't need it. Do not touch the keyboard, or better yet, move away from the computer altogether. :)
There are dubious programs that supposedly disable this feature, but I don’t recommend using them, as they often contain keyloggers.
- Some computers support automatic scheduled wake-up. If you do not need this function, you can disable it in the BIOS.
- There are many specialized programs that turn your computer on and off, as well as put it into sleep mode and wake it up at a specified time. If you don't need it, delete the program data. But these programs do not work without an active scheduled on/off function, which is controlled in the BIOS settings.
- If your computer wakes up and none of the above methods help, it means that it is either infected with a virus or one of the controllers has failed. The second is more likely, since such breakdowns are not uncommon. Contact the service center and they will help you.
Windows 7
Setting Sleep Mode
In order not to confuse you, first we will define that in this system “sleep mode” is called “hibernation”. And in the future I will use the concept of “hibernation” rather than “sleep mode”.
In the seven, Microsoft took care of the users. Here, hibernation is enabled by default. All the user needs to do is configure it. The fact is that Microsoft cares not only about the user, but also about saving energy. :) By default, the computer falls asleep after 20 minutes of inactivity. In Windows XP, automatic sleep mode is initially disabled. This is not good, because sometimes you have to leave your workplace for 30 minutes or more, but not turn off the machine. To prevent equipment from “sleeping on the job,” open the control panel, power options, and select the active plan (usually balanced). Next, you should specify the interval after which the computer can rest, or even disable sleep mode and hibernation by setting the slider to “never” in the lists. Then save the changed settings.
As for the keys that when pressed, a computer or laptop goes into hibernation, they remain the same in Windows 7. For a computer, this is the power button and the sleep key on the keyboard. For laptops, the combination FN + a specific key, power button and closing the lid. The setup is a little different, but basically everything is the same. You need to open the control panel, the power supply item and the required plan. Next, make the required settings. Once again I would like to draw your attention to the names of the modes.
Due to the wild imagination of Microsoft developers, “sleep mode” turned into hibernation, and “standby mode” received the name “sleep”. Do not confuse these terms during setup.
Why does my computer/laptop wake up on its own?
The information below not only answers the question posed, but also explains how to wake up from sleep mode in Windows 7.
- If you still use “sleep” and not hibernation, then another reason for the equipment to independently exit this mode may be wake-up timers. They are disabled in the power settings. Open control Panel, Power Options and select the plan you are using. Then find the item additional power settings and click it with a rat. After that, from the list that opens, select sleep and expand it. Find an item "allow wake timers" and clicking it, set the value to Disable. Save all changes.
- As in XP, awakening is possible by pressing any key on the keyboard. If the computer has been put into hibernation, do not touch it.
- Waking up on a schedule and the corresponding programs in the seven are also relevant. If you don't need this, simply disable the wake-up feature in the BIOS settings and uninstall the programs that control these processes.
That's probably all. This article covers all questions regarding this option. I hope you find this information useful.
Restarting your computer erases all data in the computer's memory, which may restore functionality. Before following these steps, be sure to restart your computer to resolve the issue.
If your laptop does not wake up from sleep mode, first make sure it is connected to AC power and that the power light is on.
Step 1: Activate the keyboard in Windows 7
Skip this step if your computer does not go into sleep mode or wakes up spontaneously.
Follow these steps to activate the keyboard to wake up your computer:
Some drivers can be downloaded from the HP website, others from the Microsoft website via Windows Update. Installing the latest BIOS and drivers on your computer may resolve some issues. To find available BIOS and driver updates for your printer, check the following resources in this order:

Step 4: Use Power Diagnostics in Windows 7
You can run power diagnostics to adjust your computer's power settings. Power diagnostics check parameters such as computer timeout, which determines the amount of time that the computer is idle before the monitor turns off or goes into sleep mode. Configuring these settings helps save energy and extend your computer's battery life.
To perform power diagnostics, follow the steps below.
The computer unexpectedly wakes up from sleep mode
If your computer unexpectedly wakes from sleep mode, see the information in this section to prevent hardware signals from waking your computer from sleep mode.
Step 1: Change device settings in Windows 7
Some device settings may cause your computer to unexpectedly exit a low-power state. This causes the computer to wake up from sleep mode without any reason. Activity from devices such as a wireless mouse, network, or high-definition audio device can cause the computer to wake from sleep mode. Activity from network equipment can wake the computer from sleep mode, especially if the network is always on (such as a cable modem or DSL connection).
Follow these steps to prevent signals from these devices from waking your computer from sleep mode:
Step 2: Check for problems with your connected device in Windows 7
Some devices may cause standby/sleep problems. Follow these steps to determine if there are problems with devices connected to your computer:
Disconnect all non-essential devices (printers, scanners, USB drives, etc.).
Turn on the computer with only the following devices connected: the mouse that came with the device, the monitor, and the keyboard.
If this resolves the standby/sleep issue, one of the connected devices is causing the issue. Check for problems when reconnecting each previously disconnected device. Continue connecting devices and testing until you find the device causing the problem.
Step 3: Install/Update Antivirus Application and Definitions, Run Antivirus Scan in Windows 7
Some viruses and other malware can cause sleep/hibernation problems. Therefore, it is recommended to download/update the application and antivirus application definitions and run an antivirus scan.
Run an antivirus scan to check your computer for possible viruses or other malware that may be interfering with sleep/hibernation.
For instructions on downloading and updating the antivirus application and definitions, and running an antivirus scan, see HP PCs - Removing and Preventing Viruses from Your Computer (Windows 7, Vista, XP) (English).
If the problem persists, continue to the next troubleshooting step.
Step 4: Check your system for malware

Scan options. You can use Windows Defender to scan your system for malware installed on your computer and to automatically remove (or temporarily quarantine) any malware it finds during the scan.
Open Windows Defender and scan using the following steps:
The computer does not go into sleep or hibernation mode
If your computer does not go into sleep or hibernation mode, follow these steps to troubleshoot:
Step 1: Change power settings in Windows 7
Some power settings affect the computer's ability to enter standby/hibernation mode. Make sure that the following power settings are configured to ensure that your computer uses standby/hibernation mode correctly.
The steps below provide detailed instructions.
Step 2: Update Software and Drivers
Some drivers can be downloaded from the HP website, others from the Microsoft website via Windows Update, and others only from the manufacturer's website. Installing the latest BIOS and drivers on your computer may resolve some issues.
To find available BIOS and driver updates for your printer, check the following resources in this order:
Use HP Support Assistant to automatically search for updates in Windows
HP Windows PCs come with HP Support Assistant installed. HP Support Assistant is used to automatically search for and install the latest updates for your computer. If necessary, the latest version of HP Support Assistant can be downloaded from the HP Support Assistant website (in English).

Step 3: Check your system for malware
Malware can also cause sleep/hibernation problems. Windows Defender can help prevent your computer from becoming infected in two ways:
Understanding sleep and hibernation in Windows 7
Sleep mode: Pressing the sleep key on your keyboard or clicking Sleep in the Windows 7 shutdown menu causes your computer to go into sleep mode. Closing the screen on a laptop also puts the laptop into sleep mode. Sleep mode saves the state of all applications in memory, then turns off the display and hard drive. Only enough power is consumed to maintain the data in memory. Exiting sleep mode is quick, usually taking a few seconds. Hibernation mode is useful when you need to stop your computer for a short time. However, in a laptop, powering the memory modules can drain the battery if the laptop is not connected to power.
Hibernation: Selecting Hibernation, if available in the Windows 7 shutdown menu, causes the computer to enter hibernation mode. Hibernation mode saves all running applications on your hard drive and shuts down your computer completely. While in hibernation mode, the computer does not consume power. When you restart the computer, the previous state of all running applications is restored. Restoring from Hibernate mode may take longer than recovering from Sleep mode. Use hibernation mode if you don't plan to use your computer for a long time.
