Fix Keyboard Doesn’t Work Unless Restarted on Windows 11

You sit down at your PC, wake it from sleep, and start typing. Nothing happens. The mouse moves, the screen is on, and Windows seems fine, but the keyboard is dead. You restart the computer and everything works again, until the next time the system sleeps, hibernates, or sits idle for a while.

This is one of the more common and frustrating Windows 11 problems. It affects USB, wireless, Bluetooth, and built-in laptop keyboards alike. The good news is that it is almost always a software or power-management issue rather than a hardware failure. If the keyboard works after a restart, the device itself is usually healthy. The problem is that Windows fails to initialize, wake, or re-detect it properly.

The usual culprits are:

• Fast Startup, which saves a partial system state that can leave devices in a broken condition
• USB power-saving features that switch off the port or device and fail to switch it back on
• Outdated or corrupted keyboard, chipset, or USB drivers
• Accessibility settings such as Filter Keys interfering with input
• Buggy Windows updates or conflicting third-party software
• Outdated BIOS/UEFI firmware that mishandles USB wake events

This guide walks through the fixes in a logical order, starting with the quickest and most likely to work. Try them one at a time and test after each. You don’t need to do all of them.

Tip: If your keyboard is completely unresponsive when you start, use the on-screen keyboard. Press Win + Ctrl + O if you can, or use the mouse to open Settings > Accessibility > Keyboard and turn on “On-screen keyboard.” You can also use Touch keyboard from the taskbar. This lets you follow the steps below without restarting every time.

Method 1: Run Basic Checks Before Anything Else

Some quick tests can save you a lot of time and help you narrow down the cause.

Unplug and replug the keyboard. If a USB keyboard starts working again after you reconnect it, the problem is almost certainly power management or the USB controller, which points you toward Methods 2, 5, and 6.

Try a different USB port. Move the keyboard from a front-panel port to a rear motherboard port, or from a USB 3.0 port to a USB 2.0 port. Front-panel and hub ports are more prone to power-related dropouts. Avoid unpowered USB hubs.

Check batteries and receivers. For wireless keyboards, replace the batteries and make sure the USB receiver is plugged in directly, not through a hub. Move it closer to the keyboard, since interference from other wireless devices can cause dropouts.

Test the keyboard on another device. If it also fails on another computer, the keyboard may be faulty. If it works fine there, the issue is on your Windows 11 machine.

Check the BIOS. Restart and enter BIOS/UEFI setup (usually F2, Del, or Esc at boot). If the keyboard works there, the hardware is fine and the fault lies in Windows.

Method 2: Turn Off Fast Startup

Fast Startup is a top suspect. When you shut down, Windows 11 doesn’t fully power off. It saves the kernel and drivers to a hibernation file so the next boot is quicker. A side effect is that hardware such as your keyboard may not be reinitialized correctly, which can leave it unresponsive until a full restart.

To disable it:

1. Press Win + R, type control, and press Enter to open Control Panel.
2. Go to Hardware and Sound > Power Options.
3. Click Choose what the power buttons do on the left.
4. Click Change settings that are currently unavailable (you’ll need administrator rights).
5. Under Shutdown settings, uncheck “Turn on fast startup (recommended).”
6. Click Save changes.

Now do a full restart (not a shutdown) and test the keyboard after your next sleep or shutdown cycle. Note that a Restart already bypasses Fast Startup, which is exactly why restarting fixes your keyboard while shutting down and powering on does not.

Method 3: Run the Keyboard Troubleshooter

Windows 11 includes a built-in troubleshooter that can detect and reset common keyboard misconfigurations.

1. Open Settings (Win + I).
2. Go to System > Troubleshoot > Other troubleshooters.
3. Find Keyboard and click Run.
4. Follow the prompts and apply any suggested fixes.

If you can’t find a Keyboard entry, run the Hardware troubleshooter from an elevated Command Prompt or Windows Terminal instead. Right-click Start, choose Terminal (Admin), and run:

msdt.exe -id DeviceDiagnostic

On some newer builds this legacy tool is removed or redirects to the Get Help app, so if it doesn’t launch, skip to the next method. The troubleshooter won’t always find a problem, but it costs nothing to try and sometimes clears stuck device states.

Method 4: Update, Roll Back, or Reinstall the Keyboard Driver

A corrupted or incompatible driver is a frequent cause, especially after a major Windows update.

Update the driver:

1. Right-click Start and choose Device Manager.
2. Expand Keyboards.
3. Right-click your keyboard (for example, “HID Keyboard Device” or “Standard PS/2 Keyboard”) and choose Update driver.
4. Select Search automatically for drivers.

Reinstall the driver:

1. In Device Manager, right-click the keyboard and choose Uninstall device. Do not tick “Attempt to remove the driver” unless you want to remove it fully.
2. Restart your PC. Windows will detect the keyboard and install a fresh driver.

Roll back the driver: If the problem started right after a driver update, open the keyboard’s Properties, go to the Driver tab, and click Roll Back Driver if it is available.

Manufacturer software: If you use a gaming or branded keyboard (Logitech, Razer, Corsair, SteelSeries, and so on), install the latest version of its companion software. Outdated utilities like Logitech Options or Razer Synapse are known to cause input problems, and uninstalling them can sometimes cure the issue entirely.

Method 5: Disable USB Selective Suspend

USB Selective Suspend lets Windows power down individual USB ports to save energy. When the port fails to wake up correctly, the keyboard stays dead until you reboot.

1. Open Control Panel > Hardware and Sound > Power Options.
2. Click Change plan settings next to your active plan, then Change advanced power settings.
3. Expand USB settings > USB selective suspend setting.
4. Set both On battery and Plugged in to Disabled.
5. Click Apply and OK.

This is especially effective on desktops and on laptops that are used mostly on AC power. On a laptop running on battery, you may see a small decrease in battery life.

Method 6: Stop Windows From Turning Off USB and Keyboard Devices

Beyond the global setting, individual devices can also be told to power down.

1. Open Device Manager.
2. Expand Universal Serial Bus controllers.
3. Double-click each USB Root Hub or USB Root Hub (USB 3.0) entry.
4. Open the Power Management tab.
5. Uncheck “Allow the computer to turn off this device to save power.”
6. Click OK, then repeat for every root hub in the list.

Next, do the same for the keyboard itself:

1. Expand Keyboards and open your keyboard’s Properties.
2. If there’s a Power Management tab, uncheck the same option.
3. Optionally, keep “Allow this device to wake the computer” checked so the keyboard can wake the PC from sleep.

Also check Human Interface Devices. Entries such as “USB Input Device” often have their own Power Management tab, and unchecking the power-saving option there fixes many stubborn cases.

Method 7: Check Filter Keys, Sticky Keys, and Accessibility Settings

Sometimes the keyboard is working but Windows is filtering the input. Filter Keys, for example, can ignore brief or repeated keystrokes, which can make the keyboard feel dead.

1. Open Settings > Accessibility > Keyboard.
2. Turn off Filter keys, Sticky keys, and Toggle keys.
3. Also disable the shortcuts that enable them (for example, holding Right Shift for eight seconds turns Filter Keys on).

Also confirm that the correct language and input method are selected under Settings > Time & language > Language & region, since a wrong keyboard layout can make keys produce unexpected characters.

Method 8: Repair System Files With SFC and DISM

If system files are corrupted, drivers and services that manage input may not load correctly after a cold start.

1. Right-click Start and choose Terminal (Admin).
2. Run the following commands one at a time, letting each finish:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

3. Restart your PC and test again.

The process can take 10 to 20 minutes. If SFC reports that it repaired files, that may well have been the cause.

Method 9: Update Windows, Chipset Drivers, and BIOS

Windows Update. Go to Settings > Windows Update and install all pending updates, including optional driver updates under Advanced options > Optional updates. Microsoft has released patches for various USB and input bugs over time.

Chipset and USB drivers. Visit your motherboard or laptop manufacturer’s support page (or Intel/AMD) and install the latest chipset, USB controller, and, on laptops, keyboard/HID drivers. Generic Windows drivers sometimes handle power states poorly compared with the OEM versions.

BIOS/UEFI update. If the problem started after a hardware change or has persisted through everything else, check for a firmware update. Manufacturers often fix USB wake and power-state bugs in BIOS releases. Follow the vendor’s instructions carefully, keep the PC plugged in throughout, and never interrupt the update.

Uninstall a problematic update. If the issue began right after a specific Windows update, go to Settings > Windows Update > Update history > Uninstall updates, remove the most recent one, and test. You can pause updates for a week while you wait for a fix.

Method 10: Do a Clean Boot to Find Conflicting Software

Third-party programs, particularly keyboard remappers, macro tools, overlays, antivirus suites, and older utilities, can interfere with input after startup.

1. Press Win + R, type msconfig, and press Enter.
2. On the Services tab, check Hide all Microsoft services, then click Disable all.
3. Open Task Manager (Ctrl + Shift + Esc), go to the Startup apps tab, and disable everything.
4. Restart the PC and test the keyboard through a few sleep/wake and shutdown cycles.

If the problem disappears, re-enable services and startup items in small groups until the trouble returns. The last group you enabled contains the offending program. Remove or update it. When you’re done, return to msconfig and select Normal startup.

Method 11: Fix Bluetooth Keyboard Issues

If your keyboard is Bluetooth, there are a few extra steps.

• Open Device Manager > Bluetooth, open the Bluetooth adapter’s Properties, and on the Power Management tab uncheck Allow the computer to turn off this device to save power.
• Update the Bluetooth driver from the manufacturer’s site, not just Windows Update.
• Remove the keyboard under Settings > Bluetooth & devices, then pair it again from scratch.
• Turn off the “Bluetooth Support Service” if it seems stuck, then set it to Automatic and restart it in services.msc.

Many Bluetooth dropouts after sleep come from the adapter’s power settings, so the first step is often the one that fixes it.

Method 12: Last Resorts

If nothing has worked, try these, ideally after backing up your data.

• System Restore. Roll back to a restore point from before the problem began (search “Create a restore point” > System Restore).
• Reset this PC. Under Settings > System > Recovery, choose Reset PC and keep your files. This reinstalls Windows and removes configuration problems without wiping your personal data.
• Replace the keyboard. If the same keyboard misbehaves on other computers, it may be defective. Even a cheap replacement can confirm the diagnosis.

Conclusion

A keyboard that only works after a restart is annoying, but it is rarely a sign of broken hardware. In the vast majority of cases the cause is how Windows 11 handles power states: Fast Startup saving a bad device state, USB Selective Suspend cutting power to the port, or a driver that doesn’t wake up correctly.

For most people, the fix comes from one of three steps: disabling Fast Startup, turning off USB power-saving options (both the global setting and the per-device ones in Device Manager), or updating or reinstalling the keyboard and chipset drivers. If those don’t help, work through the accessibility settings, system file repair, clean boot, and BIOS update.

Change one thing at a time and test through at least one full sleep and shutdown cycle before moving on, so you know exactly what solved the problem. And if you ever get stuck at the lock screen with a dead keyboard, the on-screen keyboard is a handy backup until you’ve fixed the underlying cause.

Frequently Asked Questions

1. Why does my keyboard work after a restart but not after shutting down and turning the PC on?

Because of Fast Startup. A restart performs a full shutdown and reload of drivers, while a regular shutdown in Windows 11 saves a partial hibernation image of the kernel and drivers. If the keyboard’s state is captured incorrectly, it may not reinitialize on the next boot. Disabling Fast Startup in Power Options normally resolves this.

2. Is this problem caused by a hardware failure?

Usually not. If the keyboard works normally after a restart, works in the BIOS, and works on another computer, the hardware is almost certainly fine. The cause is typically drivers, power management, or system settings. Hardware failure becomes more likely if the keyboard also fails on other devices or has physical issues like unresponsive keys.

3. Will disabling USB Selective Suspend or Fast Startup hurt my PC?

No. Both are optimization features, and turning them off is safe. Disabling Fast Startup may make boot times a few seconds longer, particularly on hard drives, though the difference is small on an SSD. Disabling USB Selective Suspend can slightly increase power use, which matters mainly for laptops on battery.

4. The keyboard fails even on the login screen. How can I fix things without it?

Use the on-screen keyboard from the accessibility icon at the bottom-right of the login screen to enter your PIN or password. Once you’re signed in, you can also connect a spare USB keyboard (or use a wired mouse) to navigate Settings. If you can’t get in at all, hold Shift while clicking Restart to reach the recovery environment, where you can use Safe Mode or System Restore.
