A keyboard that suddenly stops working brings everything to a halt — you cannot even type your password to log in. If you are looking up how to fix USB keyboard not working, the problem is usually simple: a dead USB port, a stuck driver, or a setting that turned the port off. This guide walks you through every fix in order, from the thirty-second checks to the deeper Windows troubleshooting, so you can get typing again.
Before you start, grab a spare keyboard if you have one — even a cheap backup — because several of these steps are much easier when you can type. If you have no working keyboard at all, most steps here can be done with a mouse alone.
Quick Answer
Unplug the keyboard, plug it into a different USB port (a rear motherboard port on a desktop), and restart the computer. If it still does not work, open Device Manager, find the keyboard under “Keyboards,” uninstall the device, and restart — Windows will reinstall the driver automatically. Also check for stuck keys, try the keyboard on another computer, and make sure Fast Startup is not blocking it at boot. If it works on another PC, the problem is your computer’s ports or drivers; if it works nowhere, replace the keyboard.
How to Fix USB Keyboard Not Working: The Full Checklist
1. Check the basics first
It sounds obvious, but most “dead keyboard” cases end here:
- Unplug and replug. Remove the USB connector, wait five seconds, and plug it back in firmly. Try a different port.
- Use a rear USB port. On a desktop, front-panel ports can fail while rear ports connected directly to the motherboard keep working.
- Skip the hub. Plug the keyboard directly into the computer, not through a USB hub or a monitor’s built-in USB ports.
- Check the cable. Wiggle the cable gently near both ends. If keys cut in and out as you move it, the cable is damaged and the keyboard needs replacing.
- Look for stuck keys. A physically stuck key (often the spacebar or a key with debris under it) can make the whole keyboard seem dead or behave erratically. Tap every key firmly once and shake out any crumbs.
If you are using a wireless keyboard with a USB dongle, replace the batteries and re-pair the dongle — low batteries cause exactly the same “not working” symptom as a dead wired keyboard.
2. Restart the computer
A proper restart clears the USB controller state. Use Start, then Power, then Restart (not Shut down, because of Fast Startup, covered below). If you cannot use the keyboard at all, click Start with the mouse, or hold the power button to force a shutdown and start the machine fresh.
3. Test the keyboard on another computer
This one step tells you where the fault lies. Plug the keyboard into a different computer or laptop:
- Works on the other computer: your keyboard is fine — the problem is in your computer’s USB ports, drivers, or settings. Continue with the steps below.
- Does not work anywhere: the keyboard itself has failed. No software fix will revive it; replace it.
4. Reinstall the keyboard driver
Corrupted or stuck drivers are a leading cause of a keyboard that is detected but types nothing. Fix it through Device Manager (you can do all of this with a mouse):
- Right-click the Start button and open Device Manager.
- Expand the “Keyboards” section.
- Right-click your keyboard entry (it may say “HID Keyboard Device”) and choose “Uninstall device.”
- Restart the computer. Windows detects the keyboard on boot and installs a fresh driver automatically.
If Device Manager shows a yellow warning triangle on the keyboard, right-click it and choose “Update driver,” then “Search automatically for drivers.” Microsoft’s official mouse and keyboard troubleshooting guide covers these same driver steps as the official first line of defence.
5. Check USB power settings
Windows can switch USB ports off to save power — including the one your keyboard uses. This causes keyboards that work after a restart but die later, or keyboards that do not wake the computer.
- In Device Manager, expand “Universal Serial Bus controllers.”
- For each “USB Root Hub,” open Properties, go to the Power Management tab, and uncheck “Allow the computer to turn off this device to save power.”
- Also open Power Options, go to advanced settings, and set “USB selective suspend setting” to Disabled.
If your keyboard keeps dropping out rather than staying dead, the guide on how to fix USB disconnecting randomly goes deeper on power-related dropouts.
6. Turn off Fast Startup
Fast Startup (enabled by default in Windows) skips full hardware re-initialisation on boot, and USB keyboards are among the devices it sometimes leaves behind — especially on older motherboards. To disable it:
- Open Control Panel, then Hardware and Sound, then Power Options.
- Click “Choose what the power buttons do,” then “Change settings that are currently unavailable.”
- Uncheck “Turn on fast startup” and save changes.
Restart once after changing this. Many users find a keyboard that never worked at the login screen starts working immediately.
7. Check BIOS/UEFI settings
If the keyboard does not work even before Windows loads — you cannot enter the BIOS or use the boot menu — the issue is at the firmware level:
- Look for a “Legacy USB Support” or “USB Keyboard Support” option in the BIOS and make sure it is enabled.
- Some very old keyboards have trouble with USB 3.0-only ports at boot; try a USB 2.0 port.
- If the keyboard works in the BIOS but not in Windows, the problem is definitely a Windows driver or setting — go back to step 4.
You will need a working keyboard to change BIOS settings, so borrow one for this step if yours is completely dead.
8. Rule out software interference
A few software culprits can silence a keyboard:
- Filter Keys: an accessibility feature that ignores brief keystrokes. Check Settings, then Accessibility, then Keyboard, and make sure Filter Keys and Sticky Keys are off.
- Recently installed software: keyboard macro tools, gaming overlays, or remote-desktop software can grab keyboard input. Uninstall anything installed just before the problem started.
- Malware: rare, but keyloggers can interfere with input. Run a scan with Windows Security if nothing else explains the failure.
Keyboard Works in BIOS but Not in Windows
This specific pattern deserves its own mention because it confuses people. If you can navigate the BIOS menus with the keyboard but it dies at the Windows login screen, the hardware is fine — a Windows driver or service is blocking input. Boot into Safe Mode (hold Shift while clicking Restart, then navigate with the mouse to Troubleshoot, Advanced options, Startup Settings). If the keyboard works in Safe Mode, a third-party driver or startup program is the culprit; uninstall recent software and update the keyboard driver as in step 4.
Laptop Keyboard vs USB Keyboard
If your laptop’s built-in keyboard works but the external USB one does not, the fault is almost certainly the USB connection — work through the port, cable, and driver steps above. If the built-in laptop keyboard is the one failing, different fixes apply (function-key locks, ribbon cable issues), and a USB keyboard is actually a fine temporary workaround while you arrange a repair.

Frequently Asked Questions (FAQs)
Why is my USB keyboard not working after a Windows update?
Windows updates sometimes replace working USB or chipset drivers with generic ones that misbehave. Reinstall the keyboard driver in Device Manager as described above, and check your PC or motherboard manufacturer’s site for updated chipset drivers if the problem started right after an update.
My keyboard lights up but does not type. What does that mean?
Lights mean the keyboard is getting power, but data is not getting through. This points to a driver problem, a damaged data wire in the cable, or a failing USB controller. Reinstall the driver first; if that fails, try another cable (if detachable) and another computer.
Can I use the on-screen keyboard as a temporary fix?
Yes. Press Windows key + Ctrl + O to open the on-screen keyboard, or find it under Settings, Accessibility, Keyboard. It is enough for logging in and navigating while you troubleshoot.
Why does my USB keyboard stop working when the computer sleeps?
This is the USB power-saving issue from step 5: Windows suspends the port and does not wake it properly. Disable “allow the computer to turn off this device” on the USB hubs and turn off USB selective suspend.
How do I know if the USB port itself is broken?
If the keyboard works in every other port but one, and other devices also fail in that one port, the port is dead or damaged. On a desktop you can usually just use a different port; if it is a laptop port, a repair shop can fix it. A USB expansion card is a cheap fix for desktops that are running out of good ports.
The Bottom Line
A USB keyboard that is not working is usually fixed within minutes: swap the port, restart, and reinstall the driver — that combination resolves the large majority of cases. The key diagnostic is testing the keyboard on a second computer, because it instantly tells you whether to fix your PC or replace the keyboard. And if you are ever completely stuck without input, the on-screen keyboard (Windows + Ctrl + O) will get you through the login screen while you work the checklist.
