Pressing a key and getting nothing back from a sleeping PC is frustrating, especially when the mouse or the power button still works. This guide explains how to fix keyboard not waking PC from sleep by checking the Windows wake permissions, USB power saving, drivers, and BIOS options that control the behavior.
Key Takeaways
- Windows only wakes a PC from a keyboard when the keyboard is allowed to do so in Device Manager.
- USB selective suspend and USB hub power saving are among the most common reasons a keyboard stays silent during sleep.
- The powercfg command shows exactly which devices are armed to wake the PC.
- Drivers, wireless dongles, and BIOS or UEFI USB wake options can all block wake-up, so each one is worth checking in order.
Before You Start
Nothing needs to be opened or unplugged inside the PC for these fixes. A few basics make the process smoother, though.
- Sign in with an administrator account, since most of the settings below need admin rights.
- Keep a spare keyboard or mouse nearby in case the main one stops responding during testing.
- Save open work before testing sleep, because each test means putting the PC to sleep and waking it again.
Common Causes
A keyboard that will not wake a sleeping PC almost always falls into one of a handful of categories. Knowing them makes the fixes easier to follow.
- The keyboard is not allowed to wake the computer in its Device Manager properties.
- Windows is cutting power to the USB hub or the keyboard to save energy.
- USB selective suspend is turned on in the active power plan.
- A driver is corrupted, outdated, or was replaced by a generic one after an update.
- The BIOS or UEFI has USB wake support turned off, or an energy-saving mode is cutting USB power during sleep.
- A wireless keyboard dongle or Bluetooth adapter is not permitted to wake the PC.
- The keyboard is plugged into a port or hub that loses power while the PC sleeps.
How to Fix Keyboard Not Waking PC From Sleep Step by Step
Work through these steps in order. Test sleep and wake after each one, because many PCs are fixed by the first two or three changes.
- Step 1: Rule out the simple causes. Put the PC to sleep, then try the space bar, a different key, and the power button. Some keyboards only wake the PC with certain keys, and some laptops are designed so that only the power button wakes them. Then move the keyboard to a different USB port, ideally one directly on the PC and not on a hub or a front-panel extension.
- Step 2: Allow the keyboard to wake the computer. Right-click the Start button and open Device Manager. Expand Keyboards, right-click the keyboard entry (usually HID Keyboard Device), and choose Properties. Open the Power Management tab, tick Allow this device to wake the computer, and click OK.
- Step 3: Check the USB hubs. In Device Manager, expand Universal Serial Bus controllers. Open the properties of each USB Root Hub and Generic USB Hub entry, go to the Power Management tab, and untick Allow the computer to turn off this device to save power. Also tick Allow this device to wake the computer if that option is present.
- Step 4: Turn off USB selective suspend. Open Control Panel, go to Power Options, and click Change plan settings next to the active plan. Choose Change advanced power settings, expand USB settings, then expand USB selective suspend setting and set it to Disabled. On a laptop, set both the On battery and Plugged in options.
- Step 5: Confirm what Windows is armed to wake from. Open Command Prompt as administrator and run powercfg /devicequery wake_armed. The keyboard should appear in the list. If it does not, run powercfg /devicequery wake_programmable to see whether Windows considers it capable of waking the PC, then repeat Step 2. The command powercfg /lastwake shows what woke the PC most recently, which helps confirm whether a test worked.
- Step 6: Reinstall the keyboard driver. In Device Manager, right-click the keyboard entry, choose Uninstall device, and restart the PC. Windows reinstalls the standard driver automatically. Also run Windows Update and install any available chipset or USB controller drivers from the PC or motherboard maker, since those drivers control how USB ports behave during sleep.
- Step 7: Check the BIOS or UEFI settings. Restart the PC and enter the BIOS or UEFI setup using the key shown at startup. Look for options such as USB Wake Support, Wake on Keyboard, Power On by Keyboard, or Resume by USB Device and enable them. Some boards also have an ErP or EuP energy-saving mode that cuts power to USB ports while the PC sleeps, and turning it off restores keyboard wake. Save the changes and exit.
Tip: Change only one setting at a time and test after each change. That makes it clear which fix solved the problem, and it avoids undoing a working setting later.
Fixing Wireless and Bluetooth Keyboards
Wireless keyboards add one more layer, because the receiver or adapter has to stay awake and be allowed to wake the PC. For a keyboard with a USB dongle, plug the dongle directly into the PC, then repeat Steps 2 through 4 for the dongle entries under Keyboards, Human Interface Devices, and the USB hubs. For a Bluetooth keyboard, open Device Manager, expand Bluetooth, open the properties of the Bluetooth adapter, and enable Allow this device to wake the computer on its Power Management tab. Fresh batteries or a full charge also matter here, because a weak battery can leave the keyboard unable to send a wake signal.
Checking Which Sleep Mode the PC Uses
Running powercfg /a in an administrator Command Prompt lists the sleep states the PC supports. Many newer laptops use Modern Standby instead of the traditional sleep mode, and wake behavior can differ from older desktops. On those systems, the power button or opening the lid is often the most dependable wake method, and keyboard wake depends more heavily on the manufacturer’s drivers and firmware.
Tip: If the keyboard wakes the PC from a short nap but not after several hours, a power-saving setting is usually cutting power to the USB port during long sleep. Revisit Steps 3, 4, and 7 first.
Common Problems and Fixes
The Power Management Tab Is Missing
The tab only appears when the device driver supports wake settings. Check the HID Keyboard Device entry and the USB hub entries for the tab, then reinstall the driver as described in Step 6. A keyboard connected through a hub or a switch may expose fewer options than one connected directly.
The Setting Turns Itself Off After a Restart or Update
A Windows feature update or a driver update can reset wake permissions. Reopen the Power Management tab and re-enable the option. Installing the latest chipset driver from the PC or motherboard maker also helps keep the setting in place.
The Mouse Wakes the PC but the Keyboard Does Not
This points to a permission problem for that single device. Repeat Step 2 for the keyboard entry, check for a second keyboard entry under Human Interface Devices, and try a different USB port.
The Keyboard Wakes the PC but Stops Working Afterward
This usually means USB power saving is cutting power after wake-up. Disable USB selective suspend and untick the power-saving option on the USB hubs, as covered in Steps 3 and 4.
Nothing Works After All Seven Steps
Test the keyboard on another computer to confirm that the keyboard itself is healthy. If it works there, check for a BIOS update from the PC or motherboard maker, since firmware updates often fix USB wake problems. Update the BIOS only by following the maker’s instructions exactly, because an interrupted update can leave a PC unable to start. If the PC still ignores every wake method, a technician can check the USB header and motherboard.
Frequently Asked Questions
Why will a keyboard not wake a PC from sleep?
The most common reasons are a missing wake permission in Device Manager, USB selective suspend, power saving on the USB hubs, outdated drivers, or USB wake support being turned off in the BIOS or UEFI.
How can a keyboard be allowed to wake a Windows PC?
Open Device Manager, expand Keyboards, open the properties of the keyboard entry, go to the Power Management tab, and tick Allow this device to wake the computer.
Why does the mouse wake the PC but the keyboard does not?
Wake permissions are set separately for each device. The mouse may be allowed to wake the PC while the keyboard is not, so the keyboard entries in Device Manager need to be checked and enabled on their own.
Does USB selective suspend stop a keyboard from waking a PC?
It can. USB selective suspend lets Windows cut power to idle USB devices, and on some systems that prevents a keyboard from sending a wake signal. Setting it to Disabled in the advanced power plan settings often fixes the problem.
Can a Bluetooth keyboard wake a PC from sleep?
Yes, on many PCs. The Bluetooth adapter must be allowed to wake the computer in Device Manager, and the keyboard needs enough battery power. Some PCs and adapters do not support Bluetooth wake at all, and the power button is the fallback in that case.
Why is there no Power Management tab for the keyboard in Device Manager?
The tab appears only for devices whose driver supports wake settings. Check the HID Keyboard Device entry and the USB hub entries, then uninstall the device and restart so Windows reinstalls the driver.
Which key wakes a PC from sleep?
Most keyboards wake a PC with almost any key, and the space bar is a common choice. Some keyboards and laptops respond only to specific keys or to the power button, depending on the firmware.
How can the cause of the last wake-up be found?
Open Command Prompt as administrator and run powercfg /lastwake. The result shows the device or event that most recently woke the PC, which makes it easy to confirm whether the keyboard is working after a change.
Can BIOS settings stop a keyboard from waking a PC?
Yes. Options such as USB Wake Support, Wake on Keyboard, or an ErP or EuP energy-saving mode can block USB wake-up. Enabling the wake option or disabling the energy-saving mode usually restores keyboard wake.
