A wireless keyboard can show a connected light and still send no keystrokes. The usual causes are weak batteries, receiver interference, a pairing glitch, Bluetooth confusion, or a driver that needs to be rebuilt.
Does this affect you?
Use this guide if the keyboard powers on or appears paired but nothing types, only the mouse in a combo set works, or the connection drops after moving a receiver or dock.
Quick checks first
These solve many wireless keyboard issues without deeper changes.
- Replace or recharge the batteries. A keyboard can light up even when the batteries are too weak to transmit reliably.
- Move the USB receiver to a port directly on the PC, not a hub, dock, monitor, or extension.
- Bring the keyboard closer to the receiver and move metal objects or large electronics out of the direct path.
- Turn the keyboard power switch off and back on to force a reconnect.
Reset the connection
If the quick checks fail, rebuild the pairing.
- For a USB receiver model, unplug the receiver, wait 10 seconds, and reconnect it to a different USB port.
- If the keyboard and receiver have connect buttons, press the receiver button and then the keyboard button within the pairing window.
- For Bluetooth, open Settings > Bluetooth & devices, remove the keyboard, restart pairing mode, and add it again from scratch.
- Open Device Manager, expand Keyboards, uninstall the keyboard or HID Keyboard Device entry, and restart so Windows reinstalls it.
- Test the keyboard on another computer if possible. If it fails everywhere, the keyboard is likely at fault.
Still not typing?
Use manufacturer software
Logitech, Microsoft, and other brands often provide apps that show battery level, receiver status, firmware prompts, and connection details that Windows does not show clearly.
Rule out wireless interference
USB 3.0 devices, external drives, routers, and crowded 2.4GHz signals can interfere with receivers. If available, try a USB 2.0 port or move the receiver with a short extension cable.
Combo receivers can fail unevenly
If a keyboard and mouse share one receiver and only one works, the receiver is probably alive. Focus on the non-working device battery, pairing, or internal failure.
When replacement is reasonable
If fresh batteries, receiver relocation, re-pairing, and another PC do not help, an older keyboard may have a worn internal antenna or failed receiver pairing hardware. Replacement is often cheaper than further repair.
