Your keyboard does not type, only some keys respond, or the wrong characters appear. This guide covers USB, wireless receiver, Bluetooth, and built-in laptop keyboards on Windows PCs.
Does This Affect You?
A dead-looking keyboard is often caused by a connection issue, low batteries, a Bluetooth pairing problem, a Windows keyboard layout, or accessibility settings. Check those before assuming the keyboard has failed.
Check the Connection
Start with the physical or wireless link.
- For a wired USB keyboard, unplug it and try another USB port, preferably directly on the computer rather than a hub or dock.
- For a wireless keyboard with a USB receiver, move the receiver to another port and confirm the keyboard power switch is on.
- For Bluetooth keyboards, remove the keyboard in Settings > Bluetooth & devices, turn the keyboard off and on, then pair it again.
- Replace batteries in any wireless keyboard, even if an LED still turns on. Weak batteries can light an indicator but fail to transmit reliably.
- For a built-in laptop keyboard, restart the laptop fully. Sleep and wake can leave input devices in a stuck state.
Fix a Driver or Settings Issue
Use these if the keyboard is connected but still behaves incorrectly.
- Open Device Manager, expand Keyboards, right-click the keyboard, and choose Uninstall device. Restart so Windows reinstalls the driver.
- If there is a yellow warning icon, choose Update driver and let Windows search.
- If keys type the wrong symbols or letters, open Settings > Time & language > Language & region and confirm the correct keyboard layout.
- Open Settings > Accessibility > Keyboard and turn off Sticky Keys, Filter Keys, and Toggle Keys if they were enabled accidentally.
Fix Specific Keys That Do Not Respond
If most keys work, focus on the individual key or group.
- Test the key in Notepad, a browser address bar, and another app to rule out an app shortcut conflict.
- Turn an external keyboard upside down and tap gently, then use compressed air at an angle to clear crumbs or dust.
- Avoid vacuuming laptop keyboards directly because suction and static can damage delicate parts.
- A sticky key on a mechanical keyboard can usually be cleaned under the keycap. Laptop keycaps are easier to break, so remove them only if you accept the risk.
If liquid was spilled, unplug the keyboard or remove batteries immediately. Let it dry upside down in a warm, dry place for at least 24 to 48 hours before testing. Powering a wet keyboard can short it. These steps are at your own risk.
Test the keyboard on another computer, or pair it with another device. If it fails there too, the keyboard hardware is probably faulty. External keyboards are often cheaper to replace than repair. Built-in laptop keyboards can usually be replaced as an assembly by a technician.
