Laptop Keyboard Not Working? Causes and How to Fix It

First, restart — it fixes more than you would think

Before anything else, save your work using an on-screen keyboard or mouse if needed, and restart the laptop. A surprising number of keyboard problems are temporary software glitches that a simple reboot clears entirely. It costs nothing and takes a minute, so always try it first.

If the keyboard works after the restart, it was a one-off glitch and you are done. If it comes back, that points to a deeper software or hardware cause, and the following steps will help you narrow it down.

Is it some keys or all keys?

This distinction matters. If only a few specific keys do not work, the cause is more likely physical — dirt, crumbs or damage under those keys. If the whole keyboard is dead, the cause is more likely a software, driver or connection problem affecting the keyboard as a whole.

Test methodically: open a document and press each key. Note exactly which work and which do not. A cluster of dead keys in one area suggests localised damage or debris, while a completely unresponsive keyboard points toward drivers or the internal connection.

Clean under sticky or dead keys

For individual non-working keys, dirt and debris are the usual cause. Turn the laptop off and upside down and give it a gentle shake to dislodge crumbs. Compressed air blown around the affected keys clears a lot of trapped debris. Sticky keys from a small spill can sometimes be eased with a barely-damp cloth on the keycap, with the laptop off.

Be gentle — keycaps and their clips are delicate. If a key feels mushy, stuck, or does not spring back, debris or a worn mechanism is likely. Cleaning resolves many single-key faults; if a key is physically broken, it can usually be repaired or the keyboard replaced affordably.

Reinstall the keyboard driver

If the whole keyboard is unresponsive, a driver glitch is a common, fixable cause. In Device Manager, find the keyboard entry, uninstall it, and restart — Windows reinstalls the driver automatically. This refreshes the software link to the keyboard and often brings a completely dead keyboard back to life.

While there, check that no accidental accessibility settings are interfering. Features like Filter Keys can make a keyboard seem unresponsive or slow to register presses. Turning these off in Windows settings restores normal behaviour if they were switched on by mistake.

Rule out a deeper fault with an external keyboard

Plug a USB or wireless keyboard into the laptop. If the external keyboard works perfectly, you have confirmed the problem is the built-in keyboard or its internal connection, not Windows or the laptop as a whole. This is a clean, decisive test and also gives you a working keyboard in the meantime.

If even an external keyboard does not work, the issue is more likely software or, occasionally, a deeper system fault — which changes the diagnosis. Either way, this test quickly separates a built-in keyboard problem from a wider one.

When the keyboard needs replacing

If cleaning and software fixes do not help and an external keyboard confirms the built-in one is at fault, the internal keyboard or its ribbon connection likely needs attention. Liquid damage, wear, or a loose internal connector are common causes. The good news is that laptop keyboards are a standard, replaceable part on most models.

Keyboard replacement is a routine repair and usually affordable, restoring full function without replacing the laptop. If a past spill is the cause, it is worth having the internals checked for residue at the same time, as liquid that reached the keyboard may have affected more than just the keys.

Getting it sorted

Most keyboard faults come down to debris, a driver glitch, or a worn or damaged keyboard — and the steps above usually reveal which. Single dead keys often clean up; a fully dead keyboard is frequently a driver fix or a straightforward replacement. Either way, you rarely need a new laptop.
