Sleep mode is a power-saving feature on your computer that reduces power consumption by shutting down most components while keeping the system state in memory for quick resumption. Waking your computer from sleep mode is usually as simple as pressing any key on your keyboard, clicking your mouse, or pressing the power button. However, there may be times when your computer doesn't wake up as expected, and you may need to troubleshoot the issue. This could involve checking your power settings, updating your operating system, or adjusting your BIOS settings.

What You'll Learn
Move the mouse
If you're having trouble waking your computer from sleep mode by moving the mouse, there are several troubleshooting steps you can take.
First, ensure that your computer is configured to wake from sleep mode when you move the mouse. To do this, navigate to the Device Manager and find your mouse device. Go to its properties, and under the 'Power Management' tab, check the box next to 'Allow this device to wake the computer'. This setting ensures that a simple mouse movement can bring your computer out of sleep mode. Don't forget to click 'OK' or 'Save' to apply the changes.
If your computer is a laptop, you may need to adjust the power settings to ensure it doesn't enter sleep mode when plugged into external power. You can also try enabling the Microsoft Bluetooth stack or your laptop's proprietary Bluetooth stack to allow wake-up via Bluetooth devices.
If you're using a wireless mouse, it's worth noting that connectivity issues or power-saving features may sometimes cause complications with sleep mode. In this case, you may need to adjust the BIOS (Basic Input/Output System) settings, which can significantly impact how your computer wakes from sleep mode. Accessing the BIOS setup during startup (usually by pressing a key like F2 or DEL) allows you to check and adjust power management settings and sleep mode settings, potentially resolving wake-up issues.
If you're using a PS/2 mouse, you can enable "resume from S3/S4/S5 by PS/2 mouse" in the BIOS settings to use the mouse to wake up the computer.
If you're still encountering issues, you can try flashing or updating the BIOS, as this has resolved similar problems for other users. Additionally, you can try disabling USB selective suspend settings and hybrid sleep mode in the advanced power settings.
If none of these steps work, you may need to force restart your computer or consult the computer manufacturer for further troubleshooting advice.

Press any key on the keyboard
Pressing any key on the keyboard is one of the simplest ways to wake up a computer from sleep mode. Sleep mode is designed to save power when you're not using your computer, and pressing a key on the keyboard signals the computer to exit sleep mode and resume normal operation.
However, if your computer does not wake up when you press a key on the keyboard, there are several troubleshooting methods you can try. First, check your power settings. On a Windows computer, you can do this by going to Start > Settings > System > Power & Battery > Screen and Sleep. Here, you can adjust the 'sleep after' time and enable 'wake timers'. You can also access the Control Panel or System Settings to modify how your computer enters sleep mode and what actions can wake it up.
If adjusting the power settings does not work, you may need to change some settings in the BIOS (Basic Input/Output System). The BIOS settings can significantly impact how your computer wakes from sleep. To access the BIOS setup, try pressing a key like F2 or DEL during startup. Once in the BIOS setup, you can check and adjust power management settings and sleep mode settings.
Additionally, you can try the following steps:
- Search for and open Device Manager.
- Double-click on Keyboards and right-click on HID Keyboard Device to select Properties.
- Under the Power Management tab, ensure that the box for 'Allow this device to wake the computer' is selected. Save the settings.
- Repeat the same process for the HID-compliant mouse.
- On the Windows search bar, type Regedit and open it.
- Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power, double-click on CsEnabled, and change its valuedata to 0. Click OK and restart your computer.
If none of these methods work, you may have experienced a system problem. Refer to the documentation that came with your computer or contact the manufacturer for further assistance.

Press the power button
Pressing the power button is an effective way to wake up your computer from sleep mode. This method works for desktop computers, tablets, and laptops. If your computer is in sleep mode, pressing the power button will quickly resume normal, full-power operation within a few seconds.
If you're using a desktop or tablet, you can customize the power button's function. To do this, go to Settings > System > Power & Sleep > Additional Power Settings. Then, select "Choose what the power buttons do." Next to "When I press the power button," select "Sleep" and then "Save changes."
For laptops, the process is slightly different. Go to Settings > System > Power & Sleep > Additional Power Settings. Choose "What closing the lid does." Next to "When I close the lid," select "Sleep," and then click "Save changes."
If your computer doesn't wake up by pressing the power button, you may need to adjust your power settings. You can do this by going to Start > Settings > System > Power & Battery. Here, you can adjust the "Screen" and "Sleep" settings to your preferences. If your monitor doesn't wake up, ensure that your computer is not in sleep or hibernate mode.
In some cases, you may need to troubleshoot to resolve issues with waking up your computer from sleep mode. This can include updating your operating system, adjusting BIOS settings, or changing USB settings. If you're experiencing persistent problems, refer to your computer's documentation or contact the manufacturer for further assistance.

Update to the latest Service Pack
Updating to the latest service pack will depend on the operating system or software you are using. Here is a guide for some of the most common systems:
Windows
Microsoft regularly releases major updates to its Windows operating systems. The latest major update to Windows 11 is Windows 11 Version 24H2, which was released on October 1, 2024. The last major update to Windows 10 is Windows 10 Version 22H2, also known as the Windows 10 2022 Update.
If you are using Windows 11, 10, or 8, you will not find a service pack installed. This is because these versions of Windows receive updates on a continual basis in smaller chunks instead of large packs. You can use Windows Update to install the latest updates automatically.
For Windows 7 or earlier versions of Windows, you can install service packs manually. The last Windows 7 service pack is SP1, and a Convenience Rollup (essentially Windows 7 SP2) is also available, which includes all patches up to April 12, 2016. For Windows Vista, the latest service pack is SP2, and for Windows XP, it is SP3.
To check which version of Windows you are running, go to Settings > System > About, and you will see the installed update next to the Version line.
SQL Server 2012
To obtain the latest service pack for SQL Server 2012, visit the Microsoft Support website. Service packs for SQL Server include hotfixes and fixes to issues reported through the Microsoft SQL Server community.
ManageEngine ADSelfService Plus
To update ManageEngine ADSelfService Plus, you will need to download and install every major version of the software until you reach the latest one. You can find these patches on the ManageEngine site.
It is important to keep your operating systems and software up to date to ensure they are working well and are secure from malicious attacks.
