Fix a laptop keyboard that is not working in Windows
Source-checked About 10 minutes
Answer
Restart, disconnect accessories, clean and inspect the keyboard, test an external keyboard, then install official updates or seek hardware service.
Check the starting state
Before changing a laptop keyboard, record whether all or selected keys fail, test before and after sign-in, disconnect accessories, inspect for debris or liquid, and compare an external keyboard. Keep the current state, exact message, and any recent change available so each result can be compared.
Choose the supported path
Separate hardware damage, accessibility features, keyboard layout, detachable connection, app-specific input, and Windows driver trouble before reinstalling software.
Restart and disconnect accessories
Restart Windows and unplug hubs, docks, and unnecessary USB devices.
Inspect the keyboard
Power down before removing loose debris. Check for stuck keys, liquid exposure, or physical damage.
Test the scope
Try the on-screen keyboard or an external USB keyboard. Test before sign-in and in multiple apps.
Update or service
Install Windows and PC-maker driver or firmware updates. If the built-in keyboard fails outside Windows too, contact the manufacturer.

Verify the result
sustained typing in two ordinary apps produces every tested key once and promptly after restart. Repeat the original task once more after reopening the relevant app, connection, or Windows session so a temporary result is not mistaken for a fix.
Troubleshoot a laptop keyboard
If keys fail before Windows loads, liquid or physical damage is possible, only the built-in keyboard fails, or accessibility settings keep returning, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
