keyboard not working can mean anything from a physical hardware failure to a driver issue to a simple settings problem. here’s how to systematically figure out which and fix it.
Step 1: Physical checks first
Before any software troubleshooting, check the obvious:
Wired keyboards: Is the USB cable fully plugged in? Try a different USB port, preferably on the rear panel directly connected to the motherboard. Try a different USB cable if possible. Test on another computer to confirm the keyboard itself works.
Wireless keyboards: Is the battery charged or do the batteries need replacing? Is the USB receiver plugged in firmly? Try removing and replugging the receiver. Is the keyboard’s power switch on?
Laptop keyboards: Check if external keyboards work. If an external keyboard works but the built-in one doesn’t, the issue is specific to the laptop’s integrated keyboard.
Step 2: Restart the computer
A basic restart resolves a surprising number of keyboard issues caused by driver glitches or Windows session problems. If you can’t type to restart normally, use the power button for a hard restart.
Step 3: Check Device Manager
Right-click Start > Device Manager > expand “Keyboards.” If there’s a yellow warning icon next to your keyboard, right-click it > Update driver. If the keyboard isn’t listed at all, right-click Keyboards > Scan for hardware changes.
If the keyboard shows with an error, try right-clicking > Uninstall device, then unplug and replug the keyboard to trigger a fresh driver installation.
Step 4: Check Filter Keys and other accessibility settings
Windows accessibility features can make the keyboard appear broken. Settings > Accessibility > Keyboard:
- Make sure Filter Keys is off – Filter Keys ignores brief or repeated keystrokes and can make typing appear non-functional
- Make sure Sticky Keys is off
- Make sure Toggle Keys is off
Step 5: Check USB power management
Device Manager > Universal Serial Bus controllers > right-click each USB Root Hub > Properties > Power Management > uncheck “Allow the computer to turn off this device to save power.”
Step 6: Try a different USB port or restart USB services
If plugging into a different port fixes it, the original port may be faulty or its driver is in a bad state. In services.msc, find “Human Interface Device Service” – restart it.
Step 7: Test in another application or Safe Mode
If the keyboard works in some apps but not others, the issue is application-specific rather than the keyboard itself. If it works in Safe Mode but not normally, a startup program or driver conflict is the cause.
