What You'll Learn
Waking a computer from sleep mode
To wake a computer from sleep mode, you can usually just press any key on the keyboard or move the mouse. If this does not work, try pressing the power button.
Troubleshooting
If the above methods do not work, there are several things you can try. First, check that your computer's drivers are up-to-date, and that the operating system as a whole is fully updated. Sleep-related problems can arise if important updates are missing.
Next, check your power settings. You can do this by opening the Control Panel and navigating to Power Options. From here, you can adjust your power plan and sleep timer. You can also create a new power plan that aligns with your specific needs, whether it's for maximizing battery life or ensuring high performance.
If you are using a wireless device, make sure it is set to 'Allow this device to wake the computer' in its power management settings.
If you are using a Bluetooth device, note that many laptop manufacturers will not allow a Bluetooth device to wake the computer from sleep mode because of the power consumption required to keep the Bluetooth radio activated. If you can open the lid of your laptop, use the embedded keyboard or pointing device or an external non-Bluetooth device to wake the computer.
If you are using a keyboard to wake your computer, make sure the Keyboard item in the Control Panel is configured to wake the computer when you press a key. If you are using a mouse, make sure USB selective suspend settings are disabled.
If you are still having issues, you may need to reboot your computer.

Troubleshooting sleep mode issues
Identify the Cause
Firstly, it is important to identify what might be causing the sleep mode issues. This could be due to a variety of reasons, such as incompatible devices, outdated drivers, custom manufacturer apps, or specific power settings.
Check for Incompatible Devices
A device connected to your PC may not be compatible with your Windows version. Common culprits include printers, scanners, gaming consoles, and webcams. To check for this, go to the manufacturer's website and look for any compatibility issues. If there are none, unplug the device and see if the sleep problem persists.
Check for Outdated Drivers
Outdated drivers can also cause sleep mode issues. Check if your drivers are up to date, especially the chipset, network, audio, and BIOS drivers. You can use tools like DriverView to check the version number, installation date, and other details of your drivers.
Disable Problematic Devices
If a specific device is causing your PC to wake up from sleep mode, you can disable its ability to do so. To identify the device, disconnect all USB devices and then reconnect them one by one, observing if the PC wakes up. Once identified, open the Start menu, search for "Device Manager," locate the device, open its Properties, and uncheck the "Allow this device to wake the computer" option.
Change Power Settings
You can also change your power settings to prevent your PC from going into sleep mode when plugged in. Additionally, you can disable the "Turn on Fast Startup" option in the power settings to see if that resolves the issue.
Run the Power Troubleshooter
Windows has a built-in power troubleshooter that can help identify and fix issues. To access it, go to Settings > Update & Security > Troubleshoot and launch the troubleshooter.
Check for Manufacturer-Specific Solutions
Different PC manufacturers may have unique solutions or custom apps that affect sleep mode. For example, Dell provides specific steps for fixing sleep mode issues on their computers.
Remember to refer to official Microsoft documentation or your PC manufacturer's support pages for detailed instructions and additional troubleshooting steps specific to your Windows version and hardware configuration.

Preventing auto-sleep
To prevent your Windows 8 computer from automatically going to sleep, you can adjust your power and sleep settings. Here are the steps you can follow:
- Go to the Start menu and select "Control Panel".
- In the Control Panel, locate and select "System and Security".
- Under "System and Security," find "Power Options".
- Click on the drop-down arrow next to "Put the computer to sleep" and select "Never".

By following these steps, you have configured your Windows 8 computer to never automatically go to sleep. You can also adjust the timeout settings to determine how long your computer waits before entering sleep mode. This can be done by going to ""Start", selecting "Settings", then "System", and finally "Power & Sleep". Here, you can set the amount of time you want your device to wait before turning off the screen and going to sleep when you're not using it.

Making it easier to wake up the computer
If you want to make it easier to wake up your Windows 8 computer from sleep mode, there are several methods you can try. Firstly, ensure that your computer's drivers are up-to-date, and that the operating system as a whole is fully updated. Sleep-related problems can arise if important updates are missing.
If you find that your keyboard or mouse won't wake up your Windows computer, the reason could be USB selective suspend, which prevents USB-connected devices from working when the PC goes to sleep. To change this, search Control Panel for Power Options, and then change the advanced settings for your selected power plan so that USB settings > USB selective suspend settings is set to Disabled.
You can also ensure that your keyboard or mouse can wake your computer from sleep by navigating to the Device Manager, finding your device, and going to its properties. 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 or keypress can bring your computer out of sleep mode.
If you're using a laptop, you can change what closing the lid does. Next to 'When I close the lid', select 'Sleep', and then select 'Save changes'. Press the power button on your laptop or close its lid to make your computer sleep.
If none of the above methods work, you may have to look into the wake timers set on your computer—that is, scheduled events that are allowed to wake your machine. Open the Start menu, search for "Edit Power Plan", and click Change Advanced Settings in the Edit Plan Settings window. Head to Sleep > Allow Wake Timers and change Battery and Plugged In to Disabled. Repeat this process for all your power plans in the drop-down menu at the top.
