Logitech Keyboard Not Working but Mouse Is? How to Fix It
A Logitech keyboard that is not working while the mouse still works is usually a power, connection, or software problem, not a broken keyboard, but it is simple to fix. Keyboards draw more current than mice, so a weak battery often fails the keyboard first while the mouse keeps running on its own charge. Wireless receivers also lose sync with the keyboard after a driver update, a Windows restart, or simply over time, which drops the keyboard’s connection without touching the mouse. Outdated Logitech drivers or corrupted software create the same one-sided failure. Working through batteries, resynchronization, and drivers in that order clears up most cases within a few minutes, and the sections below cover what to try when the basics do not solve it.
Why Is My Logitech Keyboard Not Working but the Mouse Still Works
The keyboard usually fails on its own because it draws more power and depends on a more active wireless link than the mouse does. A mouse sends small bursts of data only when it moves or clicks, while a keyboard stays ready to respond to every keystroke, so its battery drains faster and its connection to the receiver has more chances to drop.
Several separate problems produce the same symptom. A low or dead battery inside the keyboard is the most frequent cause, followed closely by a lost pairing between the keyboard and the Logitech Unifying receiver. Outdated or corrupted keyboard drivers, a loose or poorly placed USB receiver, Bluetooth interference, and Windows accessibility settings such as Filter Keys round out the list. Each cause has its own fix, and working through them in order of likelihood saves time.
How to Replace the Keyboard Batteries
Fresh batteries fix the problem more often than any other step, because a keyboard that is too low on power to send a signal still leaves the mouse untouched. Swap in a new set of the batteries the keyboard actually takes, usually AA or AAA, rather than assuming the old ones still have life left.
AA and AAA batteries power wireless keyboards, mice, remotes, toys, and other small electronics. Compare alkaline, lithium, rechargeable nickel metal hydride, and zinc carbon types, along with capacity, voltage, shelf life, and the battery size required by the device.

- Open the battery compartment. Slide or unclip the cover on the underside of the keyboard.
- Remove the old batteries. Note the plus and minus orientation before they come out.
- Insert fresh batteries. Match the polarity markings printed inside the compartment.
- Close the compartment and wait. Give the keyboard a few seconds to power on and reconnect before typing.
Rechargeable batteries that have not been swapped in months are a common trap, since a partial charge can power the receiver’s connection light without powering full keystroke transmission. If a spare set of batteries is on hand, try them even when the current batteries seem recent.
How to Resynchronize the Logitech Unifying Receiver
Resynchronizing the receiver reconnects a keyboard that has simply dropped its pairing, and it takes about five minutes with no software required. Unplug the receiver, wait roughly 10 seconds, then plug it back into the same USB port.
- Unplug the receiver. Remove the small Unifying receiver from its USB port.
- Wait 10 seconds. Give the receiver time to fully power down before reconnecting.
- Reinsert the receiver. Push it firmly into the same port.
- Press Connect on the keyboard. Most Logitech keyboards have a small Connect or pairing button on the bottom or side.
If the keyboard still does not respond, the pairing itself may need to be redone rather than just refreshed, which is where the Unifying software comes in.
How to Manually Pair a New Device in Unifying Software
Manual pairing rebuilds the connection from scratch inside the Logitech Unifying Software. Open the software, click Advanced in the bottom left corner, then choose Pair a New Device and follow the on-screen prompts. Allow a few minutes for the software to detect the keyboard, since scanning is not instant, and keep the keyboard close to the receiver while it searches.
How to Update or Reinstall Logitech Keyboard Drivers
Outdated or corrupted drivers stop the operating system from talking to the keyboard even though the hardware itself is fine. Updating the driver through Device Manager or reinstalling Logitech’s software clears up most driver-related failures, especially ones that appeared right after a Windows update.
How to Check Device Manager for Driver Errors
Device Manager shows whether Windows sees a driver problem at a glance. Open Device Manager, expand Keyboards, right-click the listed Logitech device, and choose Update driver. Windows searches automatically for a newer driver; if none turns up, right-click the same device again, choose Uninstall device, then restart the computer so Windows reinstalls the driver fresh.
When to Switch from Unifying Software to Logi Options+
Switch to Logi Options+ when the keyboard model supports it, since Logitech no longer maintains the older Unifying Software. Logitech’s own support article points newer setups toward Logi Options+, its current customization software for supported devices. Keyboards that predate Logi Options+ support still pair through the legacy Unifying Software, and several independent troubleshooting guides recommend uninstalling and reinstalling whichever software the keyboard actually uses as a general fix, particularly after a Windows update disrupts the connection.
How to Fix USB Port and Connection Problems
A receiver connection problem can leave the keyboard unresponsive even when the mouse still works. Reseat the receiver in another computer USB port, use a direct connection rather than a hub where possible, and check how Windows manages USB power.
Best USB Port for the Receiver
USB 2.0 ports occasionally work more reliably than USB 3.0 ports for wireless receivers. Connect the receiver directly to a computer USB port rather than a hub, and try another port if the keyboard is not detected. Moving the receiver closer to the keyboard and reducing nearby wireless interference can also help.
How to Turn off USB Power Management
Windows can power down a USB port to save energy, and that setting can affect the receiver. Open Device Manager, expand Universal Serial Bus Controllers, right-click each USB Root Hub, choose Properties, open the Power Management tab, and clear the checkbox for “Allow the computer to turn off this device to save power.” Repeat for every listed hub, then restart the computer.
How to Stop Bluetooth from Blocking the Unifying Receiver
A keyboard paired to the computer over Bluetooth at the same time as the Unifying receiver can prevent the receiver from detecting it at all. Turn off the keyboard’s Bluetooth pairing, or forget the Bluetooth device in Windows settings, and rely on the Unifying receiver alone.
Open Windows Settings, choose Bluetooth & devices, find the Logitech keyboard in the list, and select Remove device. Reconnect the keyboard to the receiver afterward using the resynchronization steps above. Keeping both connection methods active at once is rarely necessary and is the more common source of this particular conflict.
How to Adjust Windows Settings That Block the Keyboard
Two Windows-level settings can make a perfectly healthy keyboard appear dead: an accessibility feature called Filter Keys, and a stalled Human Interface Device service. Both are quick to check and safe to reset.
How to Turn off Filter Keys
Filter Keys is an accessibility feature that ignores brief or repeated keystrokes, and when it activates by accident it can make the keyboard seem unresponsive. Open Settings, go to Accessibility, select Keyboard, and turn off Filter Keys. On older versions of Windows the same option sits under Ease of Access Center instead.
How to Restart the HID Service
The Human Interface Device service manages communication between Windows and input devices, and restarting it can clear a stuck connection. Open Device Manager, find the keyboard or the Unifying receiver under Keyboards or Human Interface Devices, right-click it, choose Disable device, wait a few seconds, then right-click again and choose Enable device.
How to Reset the Keyboard and Check for Physical Damage
Resetting the keyboard restores its factory connection state, and a close physical inspection rules out damage as the cause. Many Logitech keyboards include a small reset button, usually recessed on the bottom, that reconnects the keyboard to its receiver when held down for several seconds.
Inspect the keyboard and the receiver for cracks, bent connector pins, or a battery compartment that does not close fully, since any of these can interrupt the signal even after every software step has been tried. A receiver with a visibly loose USB connector is worth replacing rather than continuing to troubleshoot.
Logitech Unifying receivers are USB wireless adapters that connect compatible Logitech keyboards, mice, and other peripherals to a computer. Compare receiver type, USB connector format, device compatibility, and whether the receiver supports pairing multiple Unifying devices.

Beyond that, the Fujitsu ScanSnap iX1300 I have owned since 2023 in north Columbus, Ohio has made me suspicious of turning a minor connection problem into a software project. For Logitech keyboard troubleshooting, I would put fresh batteries and receiver resynchronization ahead of reinstalling anything, because my patience is not an unlimited accessory.
What to Do if the Keyboard Still Does Not Work
When every step above has been tried and the keyboard still is not working, the most likely explanation is a failing receiver or a hardware fault inside the keyboard itself rather than a settings problem. Test the keyboard on a second computer, or test a different keyboard with the same receiver, to isolate which part has actually failed.
Restarting the whole computer, rather than just the keyboard, resolves connection issues that Device Manager and driver reinstalls did not, since a full restart clears every USB and HID process at once. Contacting Logitech support is the next step if the keyboard fails on a second computer too, since the company can advise on a warranty replacement or send a new Unifying receiver for keyboards where the original has stopped working.
Frequently Asked Questions
What if My Keyboard Is Not Supported by Logi Options+?
Keep using the Logitech Unifying Software instead, since older keyboards that Logi Options+ does not cover still pair and update through the legacy program. Reinstalling the Unifying Software after a Windows update is a common fix for exactly this situation. Logitech has stopped actively developing the older software, but it remains available for devices that never received Logi Options+ support.
Can Wi-Fi Routers or Microwaves Interfere with a Keyboard Signal?
Yes, both can interfere, along with other electronics operating on similar wireless frequencies near the desk. Moving the receiver a few inches away from a router, a phone, or other wireless equipment sometimes clears up an intermittent keyboard. This interference tends to cause occasional dropped keystrokes rather than a keyboard that never responds at all.
How Do I Know if the Problem Is the Battery or the Receiver?
Swap in fresh batteries first, since that rules out the more common and cheaper cause in under a minute. If the keyboard still will not respond with new batteries installed, unplug and reseat the receiver, then try the keyboard on a different USB port or a different computer. A keyboard that works when paired to another computer’s receiver points to a receiver problem rather than a keyboard problem.
Should I Contact Logitech Support if Nothing Else Works?
Yes, once batteries, resynchronization, drivers, and settings have all been ruled out, Logitech support can confirm whether the keyboard or the receiver has failed. Support can also arrange a replacement Unifying receiver for keyboards that no longer include their original one in the box. Have the keyboard’s model number ready, since the fix and any replacement part depend on which model is involved.
Why Does Restarting the Computer Sometimes Fix the Keyboard?
A restart clears every USB and Human Interface Device process Windows has running, which can undo a stuck driver state without any manual troubleshooting. Many keyboard connection problems that follow a Windows update resolve this way, before batteries or drivers even need to be checked. A permanent fix still requires finding out why the problem returns, so treat a restart as a first try rather than the end of the search.
Most Logitech keyboards that stop responding while the mouse keeps working come back after fresh batteries, a receiver resync, or a driver reinstall, roughly in that order of likelihood. Work through the table above from the top, check Windows settings like Filter Keys and USB power management if the basics do not help, and treat a second failed computer as the sign to contact Logitech support.
