What You'll Learn
Issues with USB devices
If you are facing issues with USB devices when trying to wake your Windows 7 computer from sleep mode, there are a few troubleshooting steps you can try.
Firstly, check your Device Manager. Go to "Device Manager" and look under "Keyboards". Right-click on your keyboard and select the Power Management tab. Here, you should see an option to "Allow this device to wake the system". Make sure this setting is enabled. If this setting is greyed out, you may need to enable the sleep/suspend settings in the BIOS.
Additionally, you can try enabling USB wake-up in your computer's BIOS. When turning on your computer, press a specific key (such as F2, DEL, F12, or ESC) to access the BIOS Setup. Navigate through the BIOS settings and look for options such as "USB Wake Up", "Wake up by USB KB/Mouse", or "USB Wake Support". Ensure that these settings are enabled.
It is also worth noting that some users have reported issues with USB keyboards not waking up their Windows 7 PCs from sleep mode. In such cases, you may need to change the keyboard to a different type, such as PS/2, or try updating to the latest available Service Pack if you are using Windows Vista.
If you are using a Bluetooth device to wake your computer from sleep mode, ensure that your laptop or computer supports this feature. Many laptop manufacturers do not allow Bluetooth devices to wake the computer due to power consumption requirements to keep the Bluetooth radio activated.
By following these steps, you should be able to resolve issues with USB devices when trying to wake your Windows 7 computer from sleep mode.

Bluetooth device problems
If your Windows 7 computer won't wake from sleep mode, it could be due to a few reasons. Firstly, check if your keyboard is configured to wake the computer when a key is pressed. If not, go into your Keyboard settings in the Control Panel and configure it to do so. Additionally, ensure that your Sleep key is configured correctly. If not, pressing it again might resolve the issue. If you are using Windows Vista, ensure that you have updated to Service Pack 1 or a later version.
Now, for Bluetooth device problems, here are some troubleshooting steps you can try:
- If you are using a laptop, check if you can open the lid. If so, try using the embedded keyboard, pointing device, or an external non-Bluetooth device to wake your computer.
- If you are unable to open the lid or if your computer is plugged into an external power source, change the Power settings in Windows to prevent the computer from going into Sleep mode when plugged in.
- Remove the Bluetooth device and then add it again: Go to Start > Settings > Bluetooth & devices > Devices. Select More options for the Bluetooth device and then select "Remove device" > "Yes". To pair your Bluetooth device again, go to Start > Settings > System > Troubleshoot > Other troubleshooters, and then select "Run" next to Bluetooth and follow the instructions.
- If you recently upgraded to Windows 11 or installed updates, your current driver may be designed for an earlier version of Windows. To check for driver updates, go to Device Manager and select Bluetooth, then select the Bluetooth adapter name.
- If Windows can't find a new Bluetooth driver, visit your PC manufacturer's website and download the latest Bluetooth driver from there.
- If Windows doesn't reinstall the driver automatically, open Device Manager and select Action > Scan for hardware changes. You may need to contact your PC manufacturer to get the latest drivers for your Bluetooth adapter.
- If you are using a Windows 11 device, you can run the automated Bluetooth troubleshooter in the Get Help app, which will automatically diagnose and attempt to fix most Bluetooth problems.
Remember, an outdated or incompatible driver is one of the most common causes of Bluetooth connection problems, so ensure your drivers are up to date.

- Right-click on the Start menu and select "Device Manager."
- Locate and expand the "Display adapters" section.
- Right-click on your graphics card and select "Disable device."
- Wait for a few seconds and then right-click on the disabled graphics card, and select "Enable device."
Reset Graphics Card Settings
If none of the above solutions work, consider resetting your graphics card settings to their defaults:
