Why Can't Computer Wake Up from Sleep Windows 10: How to Fit It?

In general, to wake up the computer in the sleep mode, you just need to click the mouse or tap the keyboard once. But if it doesn't work, you need to troubleshoot the problem after the reboot. We can analyze the reasons why can't computer wake up from sleep from 3 aspects: hardware glitches, software glitches and system errors. In this post, we will point out those reasons from 3 aspects one by one and give you specific solutions. If you are more interested in solutions, click on the list below to have a quick view of a specific method.

There are some hardware glitches which may cause the problem. But before checking the hardware, you need to make sure if the keyboard and mouse has the permission to wake up Windows.

Reason 1: Keyboard and mouse don't have wake up permission

Your keyboard may not have permission to wake the computer. So is your mouse. Therefore you should check and allow keyboard and mouse to wake Windows 10 first.

Steps:

1. Search for and open "Device Manager" from the start menu.

2. Find the "Keyboards", expand it and right-click to choose "Properties".

3. In the "Power Management" tab, tick Allow this device to wake the computer option. Then tap on "OK".

4. Come back on "Device Manger", expand Mice and other pointing devices and open its Properties.

5. Repeat Step 3 for the mouse.

Reason 2: Keyboard and mouse are malfunctioning

Perhaps your keyboard or mouse is malfunctioning, or it is malfunctioning in both. There is an easy way to test whether the keyboard and mouse are malfunctioning. Just connect your keyboard and mouse to any computer which can wake up from the sleep mode by its keyboard and mouse. If the computer comes out of sleep mode by using your keyboard or mouse, it means they are well-functioning.

If there is a problem, go fix it by updating the driver of keyboard and mouse. And then check if this is working fine. If the update doesn't work, you need to buy a new one.

Steps:

1. Search for and open 'Device Manager' from the start menu.

2. Double-click on 'Keyboards' and right-click on Keyboard Device to select Update Driver.

3. Do the same thing for the mouse.

Except for the keyboard and mouse, there may be other hardware problems. Here I recommend Five Free Windows Hardware Diagnostic Tools to check the problem of your computer, which is convenient for you to know the specific hardware problem.

Here comes to the system errors. There may be many system problems that prevent the computer from waking up from sleep mode. Among them, the system update and the graphics driver problem is seen most often. If you solve these common problems, you are more likely to solve the problem of computers not being able to wake up from the sleep mode.

Reason 3：The system update

Among many software problems, the most common and easily overlooked one is the system update. Whether it is a minor feature update or a patch update, when your computer informs you of a restart for an update or the 'update and restart' prompt appears on the power option, your computer is likely not to wake up from the sleep mode. So when your computer informs you of rebooting the computer to update, don't put your computer into the sleep mode.

Reason 4: The graphics driver is damaged or not updated

Because the sleep mode shows itself on the display, it is associated with the display adapter. Without the intact and undamaged graphics card driver or the updated graphics card, the sleep mode on Windows 10 cannot work. So it is needed to update the graphics driver frequently. The source of the steps is support.microsoft.com.

Steps:

1. Right-click on the start icon of your desktop or press Win + X key on your keyboard to open Menu. Then choose 'Device Manager'.

2. Expand the "Display adapters", right-click the graphic card to choose Update Driver.

3. Select 'Search automatically for updated driver software'.

4. When the best drivers are already installed, close all windows.

Reason 5: Other system errors

In addition to the above reasons, there may also be problems caused by system errors. How to solve the problem when we don't know what is it? We can use a built-in service of Windows system -- troubleshoot settings to find and fix problems related to the sleep mode.

Steps:

1. Type 'Troubleshoot settings' into the search box in the start menu and open its interface.

Scroll the mouse, click 'Power' in Find and fix other problems and choose Run the troubleshooter. Then the computer will automatically help you find and repair power problems.( Because in the Windows system, sleep mode is a power issue, so choose power to find.)

3. When the pop-up window shows 'troubleshooting has completed', close the interface.

You can set the Windows to repair the problems automatically.

1. Type 'Troubleshoot settings' into the search box in the start menu and open its interface.

2. Then click "Recommended troubleshooting" settings.

3. Choose Fix problems for me without asking in the Recommended troubleshooting interface.

After figuring out hardware problems and system errors, your computer should be able to get out of sleep mode. if it doesn't, you need to consider the software problem First, you need to make sure that your computer is away from any malware or virus. You can use an official tool to check the malware and virus, like Microsoft Safety Scanner. Then, you can think about the other reasons which prevent the computer from waking up from sleep mode.

Reason 6: Fast startup mode is enabled on your system

Fast startup is a feature of Windows 10 designed to reduce the time it takes for the computer to start from a complete shutdown. However, sometimes it prevents the computer from performing regular shutdown operations and may make your computer unable to wake up from the sleep mode. So when the problem happens, it's time to turn off fast startup on your Windows 10.

Steps:

1. Open Run process by pressing Windows + R.

2. Type 'powercfg.cpl' and click on the "OK" button.

3. Click the 'Choose what the power buttons do' on the left side, and choose the 'Change settings that are currently unavailable'.

4. Untick the 'Turn on fast startup (Recommended)' under the Shutdown settings

5. Click the "Save changes" button.
