What You'll Learn
Waking a PC from sleep with a keyboard
Waking a PC from sleep using a keyboard is a convenient option, as it lets you resume work from where you left off without having to press the power button. By default, this option is enabled on most PCs. However, sometimes it might not work as it should, or the option is disabled.
If your keyboard doesn't wake your PC from sleep, you need to check an option to confirm it's allowed to do so. To do this, right-click on the Start Button, or press Win + X, to open the Power User menu. Select Device Manager. You'll see a list of categories for the devices connected to your PC. If you can't wake your PC from sleep with the keyboard, click the arrow next to Keyboards. This list will show one or more entries for your PC keyboard. On each entry's Power Management tab, make sure that the "Allow this device to wake the computer" box is checked. Click OK when done, making sure to do this for all entries.
If you don't see the Power Management tab on any of your keyboards, either your hardware doesn't support waking the computer from sleep, or you don't have the proper drivers installed. Check your manufacturer's guide on updating Windows drivers for help with getting the latest ones. Also, make sure that your keyboard is working properly overall. If it suddenly doesn't do anything, it won't wake your PC from sleep.
If you are using a Microsoft keyboard, you may be unable to wake the computer from sleep or standby mode by using your keyboard. This issue may occur if you are running Windows Vista and have not updated to Service Pack 1 or a later version. The Basic Input/output System (BIOS) system that is installed on the computer reduces power to the port to which the input device is connected.
If you are using a Bluetooth keyboard, your computer might not receive Bluetooth signals while it's asleep. You can't tweak this in the Device Manager, so your best bets are to update your Bluetooth driver or consider getting a newer Bluetooth adapter with better power management.

Troubleshooting when a PC won't wake from sleep
If your PC won't wake from sleep mode, it might have automatically transitioned into hibernation mode after being in sleep mode for an extended period. In hibernation mode, the device cannot be awakened via the keyboard; you must press the power button to rouse it. If you are using a battery-powered device, ensure it is connected to a power source and that the battery charging indicator is illuminated. Then, attempt to press the power button to wake the device. If the device still does not wake, press and hold the power button for 15 seconds to force a shutdown. Afterward, restart the device and follow the troubleshooting steps below to prevent the issue from recurring.
If your keyboard or mouse won't wake your PC from sleep, you need to check an option to confirm they're allowed to do so. Right-click on the Start Button, or press Win + X, to open the Power User menu. Select Device Manager. You'll see a list of categories for the devices connected to your PC. If you can't wake your PC from sleep with the keyboard, click the arrow next to Keyboards. This list will show one or more entries for your PC keyboard. On each entry's Power Management tab, make sure that the "Allow this device to wake the computer" box is checked. Click OK when done, making sure to do this for all entries. Your keyboard should now wake your PC from sleep. If you have an issue with your mouse not waking your PC from sleep as well, repeat these steps for the Mice and other pointing devices category in the Device Manager.
If you don't see the Power Management tab on any of your keyboards or mice, either your hardware doesn't support waking the computer from sleep, or you don't have the proper drivers installed. Check a guide on updating Windows drivers for help with getting the latest ones. Also, make sure that your keyboard and mouse are working properly overall. If they suddenly don't do anything, they won't wake your PC from sleep.
If you use a Bluetooth mouse and keyboard, your computer might not receive Bluetooth signals while it's asleep. You can't tweak this in the Device Manager, so your best bets are to update your Bluetooth driver or consider getting a newer Bluetooth adapter with better power management. Many laptop manufacturers will not allow a Bluetooth device to wake the computer from sleep mode because of the power consumption requirements to keep the Bluetooth radio activated (Bluetooth paging can consume up to 15% of the computer’s power). Therefore, 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 cannot open the lid or if you have it plugged into external power, you can change the Power settings in Windows to not go into Sleep mode when plugged in.
If the problem persists after all troubleshooting steps are completed, please back up your personal files, then reset the device to its original configuration. If your issue remains unresolved, contact the manufacturer's customer service for further assistance.

Changing power settings to prevent sleep mode
Changing power settings is an effective way to prevent your PC from going into sleep mode. This is especially useful if you need continuous access to your computer for quick file retrieval, ongoing software tasks, or business operations.
Windows 10 and Windows 11
For Windows 10 and Windows 11, you can adjust the power settings by going to Start, then selecting Settings > System > Power & Sleep. Here, you can modify when your device enters sleep mode under the Sleep section. Set "When plugged in, put my device to sleep after" to "Never" to prevent sleep mode when your device is plugged in. You can also adjust the "On battery" option if you want your device to stay awake on battery power.
Additionally, you can access the Additional power settings to fine-tune specific aspects, such as disabling sleep mode when the lid is closed (for laptops) or adjusting the hard drive sleep timer. You can also select the High-Performance Power Plan if it is available, which prioritizes keeping your computer active over power-saving features.
Laptops, Desktops, and Tablets
For laptops, desktops, and tablets, you can change what the power buttons do to prevent sleep mode. Go to Start, select Settings > System > Power & Sleep > Additional power settings. Next to "When I press the power button" or "When I close the lid" (for laptops), select "Sleep" and then "Save changes."
Control Panel
Another way to prevent sleep mode is by using the Control Panel. Press the Windows key on your keyboard, type "Control Panel" into the search bar, and press Enter. Click on "Hardware and Sound," then "Power Options." On the left side, select "Change when the computer goes to sleep" and modify the sleep settings to your preference.
Hibernate Mode
If you want to prevent sleep mode and conserve power, you can also consider using hibernate mode. Hibernate mode uses less power than sleep mode and allows you to resume your work quickly. To enable hibernate mode, go to Start, select Settings > System > Power & Sleep > Additional power settings. Under "Shutdown settings", select the "Hibernate" checkbox (if available) and then "Save changes."
Wake Timers
You can also prevent your computer from waking up automatically by changing the wake timers. Press and hold the Windows key, then press "Q." Type "Power Options" in the search box, then click "Power & Sleep Settings." Click on "Additional power settings," then "Change plan settings" and "Change advanced power settings." Click the plus sign next to "Sleep" and "Allow wake timers." Change the settings for "On battery" and "Plugged in" to "Disabled" or "Important Wake Timers Only."
