The mouse is on the desk, plugged in, and Windows acts like it doesn't exist. No cursor on screen. No new device sound. Nothing in Bluetooth & devices. This is one of the most frustrating "is it the mouse or the PC?" problems in computing — and the answer is usually the PC, with a fix that takes under 10 minutes.

Work the steps below in order. They go from "fix in 10 seconds" to "reinstall the driver". If you get to the bottom and still nothing, see the hardware-test section.

Step 1: Try a Different USB Port (10 seconds)

USB ports fail silently — the port is dead but everything around it works. Move the mouse cable or wireless receiver to a different port, ideally one of the rear motherboard ports (more reliable than front-case ports) and one labelled USB 2.0 (less interference). If the mouse instantly springs to life, the original port is dead and you've just diagnosed your motherboard.

Step 2: Try a Different Cable / Replace AA Batteries

For wired mice, the most common failure point is the USB-A or USB-C connector at the cable's PC end — micro-fractures from years of bending. Swap in a known-good cable. For wireless mice with replaceable batteries, install fresh ones and listen for a click or LED on the receiver.

Bluetooth-only mice that won't pair: open Settings → Bluetooth & devices → Devices, remove the mouse, and re-pair from scratch.

Step 3: Test on a Different PC (2 minutes)

This is the most diagnostic step. If the mouse works on a second computer, the hardware is fine and the original PC has a software or USB problem — go to step 4. If it doesn't work on either, the mouse itself is dead — go to "Replacement" at the bottom.

Step 4: Reinstall the Mouse Driver (Keyboard-Only)

Even without a mouse you can do this:

  1. Press Win + X, then press M to open Device Manager.
  2. Use arrow keys to navigate to Mice and other pointing devices and press the right arrow to expand.
  3. Highlight your mouse, press Shift + F10 for the context menu.
  4. Choose Uninstall device, confirm.
  5. Press Alt + A, then A again to "Scan for hardware changes".

Windows will reinstall the generic HID-compliant mouse driver. Detail on how this discovery works is in Microsoft's HID architecture docs.

Step 5: Update the USB Host Controller Driver

If no USB device works on a particular set of ports, the USB controller driver is broken — not just the mouse driver. In Device Manager, expand Universal Serial Bus controllers. Right-click each "USB Root Hub" or "USB xHCI Controller" entry → Update driver → Search automatically. Windows will reach out to Microsoft Update for the latest signed version.

Step 6: Disable USB Power Management

Windows turns USB ports off to save power. If a port shut down and won't wake up, the mouse looks dead.

  1. Open Device Manager → Universal Serial Bus controllers.
  2. Right-click each USB Root Hub → Properties → Power Management tab.
  3. Uncheck Allow the computer to turn off this device to save power.
  4. Repeat for every Root Hub. Restart.

Step 7: Enable Legacy USB Support in BIOS

If the mouse works in Windows but is dead at the boot/BIOS screen — or vice versa — you need Legacy USB Support enabled. Reboot, mash Del / F2 / F10 to enter BIOS (varies by motherboard), find Advanced → USB Configuration, and enable Legacy USB Support and XHCI Hand-off. Save and reboot. We cover this in detail for keyboards in our BIOS keyboard detection guide — the same steps apply to mice.

Step 8: Roll Back a Recent Windows Update

If detection broke right after a Windows Update, roll it back: Settings → Windows Update → Update history → Uninstall updates. Look for cumulative updates dated within a day of when the mouse stopped. KB5034441 and several 2024–2025 updates have caused USB-detection regressions on specific chipsets.

When the Mouse Is Actually Dead

If steps 1–8 all fail and the mouse fails on a second PC too, replacement is the answer. Before discarding, check iFixit for a teardown of your model — a dirty USB-C port or a snapped cable inside the strain-relief is sometimes a 10-minute repair. Razer and Logitech both offer warranty replacements for in-warranty hardware faults.

Frequently Asked Questions

Can I fix a missing mouse using only the keyboard?

Yes — every step in this guide is keyboard-friendly. Use Win+X for the power-user menu, Tab and arrow keys to navigate, and Space or Enter to confirm. Win+Ctrl+Enter starts Narrator if you need audio guidance.

Why does my mouse work in BIOS but not in Windows?

BIOS uses a generic legacy USB driver, so detection there proves the hardware and ports are fine. The Windows-specific failure points are HID drivers, USB host controller drivers, and power management — covered in fixes 4–7.

What if my mouse works in Safe Mode but not normally?

A third-party driver or background app is interfering. Boot normally and use Task Manager → Startup to disable everything non-Microsoft. Restart and re-enable items one at a time until the culprit appears.

I have a brand-new mouse — could it be DOA?

Yes but it's rare (~1% of new units). Test on a second computer for 5 minutes to confirm. If it fails on both, file a return request with the seller; reputable retailers replace DOA peripherals without question.

Will a clean Windows install fix this?

Almost always — but it's a sledgehammer for what is usually a 5-minute driver fix. Try every step in this guide first. Reinstall Windows only if all of them fail and you can confirm the mouse works on another PC.
