Windows 11 Keyboard or Mouse Not Working? How to Fix It

Windows 11 Keyboard or Mouse Not Working? How to Fix It

You go to type or move the cursor and nothing happens — the keyboard’s gone silent, the mouse pointer won’t budge, or either one works for a few minutes and then drops out again. It can be a wired device or a wireless one, and it’s a different problem entirely from a device that’s simply dead, which is a hardware replacement rather than something Windows can fix.

Between “working fine” and “needs to be replaced,” there’s a wide middle ground where Windows itself is the reason a perfectly good keyboard or mouse isn’t responding, and that middle ground is where almost every one of these cases actually lands. Working through it in order, cheapest checks first, gets you to the real cause without guessing.

Quick explanation: this guide covers the basic physical checks worth doing first, confirming Windows even detects the device in Device Manager, telling a driver issue apart from a genuinely dead device, an accessibility setting that can make a keyboard feel broken when it isn’t, USB power-saving turning a port off, and Bluetooth-specific pairing issues for wireless keyboards and mice.

Quick Answer

Most keyboard and mouse problems on Windows trace back to one of three things — a driver issue Device Manager will flag directly, a USB port that’s been power-managed off to save energy, or, for wireless devices, a dropped Bluetooth or dongle connection. Basic physical checks — a different USB port, fresh batteries, the dongle actually seated — rule out the simplest causes before you go further. If the keyboard specifically is misbehaving rather than being unresponsive, an accessibility setting like Filter Keys is also worth ruling out before assuming anything’s actually broken.

Start With the Basic Physical Checks

Before touching any Windows setting, it’s worth spending thirty seconds on the physical side of things, since a surprising number of “broken” keyboards and mice turn out to be a connection problem rather than anything Windows is doing. These checks cost nothing and rule out a genuinely dead device before you invest time troubleshooting a device that’s actually fine.
For a wired device, try a different USB port, ideally one directly on the motherboard rather than through a hub or a monitor’s built-in ports. For a wireless one, check that the USB dongle hasn’t worked itself loose and swap in fresh batteries even if the current ones seem fine, since a mouse or keyboard running low on power often acts intermittent long before it dies outright. If you have access to a second PC, plugging the same device into it is the fastest way to tell a dead device apart from a Windows-side problem.
If the device behaves the same way on a different port, different batteries, and even a different computer, that points toward the device itself rather than anything on this PC — otherwise, it’s worth moving on to what Windows actually sees, which is where the next check comes in.

Confirm Windows Actually Detects the Device

Once the physical basics check out, the next question is whether Windows even knows the device exists. A keyboard or mouse showing up in Device Manager with a yellow warning triangle next to it is a very different situation from one that isn’t listed there at all, and telling those two apart early saves a lot of wasted troubleshooting.
A warning triangle means Windows sees the device but has a problem with the driver running it — that’s fixable through a driver update, rollback, or reinstall. A device missing entirely from the list means Windows never registered the connection in the first place, which points back toward the port, the cable, the dongle, or a power issue rather than anything driver-related.
Fixyfier’s Windows Tools section puts a Device Manager shortcut a click away, which gets you straight to this exact view without digging through Windows Settings first.

A Driver Problem, or Windows Simply Losing Track of the Device

Not every case where a device goes missing from Device Manager means the driver is broken. Sometimes Windows has simply lost track of a keyboard or mouse that’s still physically connected and working — a brief power blip on the USB bus, a sleep/wake cycle that didn’t fully restore every peripheral, or a dongle that reconnected slightly differently than it did last time.
In that situation, reinstalling the driver is more than the problem actually needs. Forcing a fresh hardware scan tells Windows to go looking for connected devices again from scratch, which re-detects a device that’s still there without touching the driver at all — worth trying before assuming anything needs to be reinstalled.
Fixyfier’s Fix & Repair section includes Fix Hardware Detection Issues, which does exactly this — forcing Windows to detect newly connected or missing USB devices, monitors, and peripherals in one step.

When an Accessibility Setting Is Actually to Blame

If it’s specifically the keyboard acting up — a key that seems to need extra presses to register, or repeated letters appearing from a single press — the cause is sometimes a Windows accessibility feature rather than the hardware itself. Filter Keys is designed to ignore brief or repeated keystrokes, which is genuinely useful for some people but can make an ordinary keyboard feel faulty if it’s been switched on by accident.
Sticky Keys can cause similar confusion in a different way, changing how modifier keys like Shift and Ctrl behave when pressed on their own. Both settings live under Windows’ accessibility options and are usually toggled by a keyboard shortcut held down too long rather than deliberately, which is exactly why they’re easy to trigger without noticing and easy to overlook as the explanation afterward.
This is worth ruling out before assuming a hardware fault, especially when it’s a specific key or a repeated-press pattern behaving strangely rather than the entire keyboard being unresponsive — that distinction alone usually points toward a setting rather than a dying device.

One Thing Worth Knowing

Researching This From Your Phone Because the PC Won't Cooperate

When the keyboard or mouse on your main PC is the thing acting up, it's not exactly comfortable to type a search into that same machine — so there's a good chance you're reading this from a phone instead, on whatever Wi-Fi happens to be nearby. NordVPN keeps that lookup session encrypted no matter which device you end up troubleshooting from.

USB Power Management Switching the Port Off

The same power-saving feature that can quietly drop a Wi-Fi adapter’s connection applies to USB ports too. Windows is allowed to power down a USB hub or an individual port to save energy, and on a laptop running on battery this can make a plugged-in mouse or keyboard stop responding for a moment before it comes back, or fail to wake up properly at all.
One related check worth running is which devices are currently allowed to wake the system from a low-power state, since that setting shares the same underlying power management system that can be starving a USB port of power in the first place.
powercfg /devicequery wake_from_any
That command lists the devices currently permitted to wake the PC — a useful related diagnostic rather than a direct fix on its own. The actual toggle for USB power management lives on the per-device Power Management tab in Device Manager, where unchecking “Allow the computer to turn off this device to save power” on the affected keyboard or mouse (or its USB hub) stops Windows from cutting power to it in the first place.

Bluetooth-Specific Pairing and Connection Drops

Wireless devices add one more layer that wired ones don’t have to deal with, and for Bluetooth keyboards and mice specifically, the symptom is usually one of two things: the device pairs fine and then drops the connection at random, or it refuses to pair again at all after previously working.
In both cases, the device itself is often not the problem. Windows’ Bluetooth service can get into a stuck or unresponsive state that has nothing to do with the keyboard or mouse sitting right next to the PC, and restarting that service resolves a surprising share of “my Bluetooth mouse keeps disconnecting” cases without touching the device at all.
Fixyfier’s Fix & Repair section includes Fix Bluetooth Issues, built for exactly this — restarting the core Windows Bluetooth service to clear frozen connections, an unresponsive device, or a greyed-out Bluetooth toggle in one step.

Frequently Asked Questions

Why does only one specific key or mouse button misbehave instead of the whole device?

A single misbehaving key or button usually points somewhere different than a fault affecting the whole device. It can be physical wear on that one switch, a driver remapping issue on a device with programmable buttons, or an accessibility setting like Filter Keys reacting oddly to how that particular key gets pressed. A driver problem or a dead connection, by contrast, tends to take out the entire device at once rather than picking out one key.

Does this affect wired devices the same way as wireless ones?

Some causes overlap and some don’t. Driver issues, accessibility settings, and USB power management can all affect a wired keyboard or mouse exactly the same way they affect a wireless one. Bluetooth pairing problems and dying batteries obviously only apply to wireless devices, which is why a wireless setup has more potential failure points even though both share the same core troubleshooting steps.

Could a recent Windows update have caused this?

It’s a reasonable thing to suspect, and it does happen. An update can install a generic driver over one that was working fine, reset a power management setting back to its default, or occasionally flip an accessibility option during the upgrade process. If the problem started right around when an update installed, checking Device Manager for a recently changed driver is a good place to start before looking anywhere else.
