Update keyboard driver
Standard keyboards generally use built-in operating-system support. A laptop's brightness, volume, or special keys may additionally depend on model-specific hotkey, system-control, chipset, or firmware components.
Check layout, accessibility settings, connection, and another keyboard before changing software. Test whether the keyboard works in firmware or recovery screens; a spill, damaged cable, or failure outside Windows is unlikely to be fixed by a driver.

Key Takeaways
- 1
Keep a keyboard, touchpad, or other input route available.
- 2
Use Windows Update and the exact laptop maker for special keys.
- 3
Reinstall only the relevant device through supported instructions.
- 4
Do not remove every USB controller for one keyboard symptom.
Separate settings and hardware from drivers
Check the selected keyboard layout, accessibility features, wireless battery, cable, receiver, and USB port. Test an external keyboard and, when possible, the built-in keyboard before Windows starts. If it fails outside Windows, investigate the keyboard, cable, firmware settings, or mainboard.
For function-key problems, identify the laptop model and read its hotkey or system-control package notes. A keyboard layout that looks the same on two notebooks does not make their support packages interchangeable.
- Keep another input method connected before making changes.
- Record the keyboard model and operating-system version.
- Check the computer maker's exact package and release notes.
Reinstall one keyboard device
Use Windows Update first. If the official instructions call for Device Manager reinstallation, target the relevant keyboard device and restart so the standard driver can be detected again. Save work before making the change and do not select a package for another notebook.
Do not remove every USB controller to refresh one keyboard. That can disable the keyboard, mouse, storage, and recovery access simultaneously. Leave signature protections enabled and stop if a package is rejected for the model or operating system.
Verify typing and special keys
Test letters, modifiers, function keys, layout switching, brightness or volume controls, sleep and wake, and the original application. If only one application has a problem, inspect its shortcut and input settings. Physical key failures, liquid damage, and intermittent cables need service or replacement rather than repeated reinstallations.
- Record the previous version if rollback becomes necessary.
- Use supported rollback only when a recent package caused a reproducible regression.
- Keep recovery credentials available if firmware is involved.
Common Questions
How do I reinstall a standard keyboard driver?
Keep another input method available, follow the supported Windows Update or Device Manager procedure for the specific device, and restart for redetection.
Why do letters work but function keys fail?
Special keys may depend on the laptop maker's hotkey or system-control software rather than the standard keyboard class driver.
