The Logitech M510 is a popular, reliable wireless mouse, but it is prone to issues such as cursor freezing, erratic movement, or complete loss of connectivity. These problems often stem from outdated drivers, faulty software, or simple power and connection glitches, not hardware failure.
To restore the smooth, precise function of your M510 mouse, this guide provides a systematic set of troubleshooting steps, beginning with the most critical factor: ensuring your system drivers are perfectly stable.
Part I: Driver and Software Integrity (The Core Fix)
The primary cause of erratic behavior or connectivity loss is a conflict between the mouse, the Logitech Unifying Receiver, and your PC's controller drivers.
Method 1: Automated Driver Update with Driver Sentry
Manually updating the various drivers required for the M510 (including the mouse driver, Unifying Receiver driver, and USB controllers) can be tedious. A specialized utility streamlines this process, ensuring all necessary drivers are current and compatible.
Download and Install:
Click the "Download" button to download the software package.
Install it on your Windows PC.
Run Scan:
Launch the application and click the "Scan" button.
The software will perform a deep analysis of your system, focusing on peripheral and controller drivers.
Install the Update:
The results will show you a list of all drivers that need attention. Select the necessary drivers and click the "Repair Now" button.
Driver Sentry will download and install the latest, certified versions specific to your Logitech M510 and its receiver.
Restart Your PC:
After the installation is complete, restart your computer.
Stable drivers are essential for consistent and responsive mouse performance.
Method 2: Reinstall Mouse Driver via Device Manager
This method forces Windows to forget the existing driver configuration and load a fresh copy.
Press Windows Key + X and select "Device Manager".
Expand the "Mice and other pointing devices" category.
Right-click on your Logitech M510 entry (often labeled as "HID-compliant mouse" or "Logitech Unifying Receiver").
Select "Uninstall device". Do NOT check the box to delete the driver software.
In the Device Manager menu, click "Action" > "Scan for hardware changes". Windows will automatically detect the uninstalled device and load a fresh default driver.
Restart the PC.
Part II: Power and Connectivity Checks
These steps address physical connection issues, which are often mistaken for software problems.
Method 1: Check Battery and Power Cycle
Low battery power is a very common reason for erratic movement or complete failure.
Replace Batteries: Immediately replace the old AA batteries in the M510 with a brand new set.
Power Cycle: Turn the M510 off using the switch on the bottom, wait 10 seconds, and turn it back on.
Check Light: The indicator light on the mouse should flash green when turned on, confirming adequate battery power.
Method 2: Reseat Unifying Receiver and Re-Pair
The USB connection may have glitched, or the mouse may have lost its pairing link to the receiver.
1). Change USB Port: Unplug the Logitech Unifying Receiver and plug it into a different USB port on your PC (try a port on the front or a different side).
2). Re-Pair Device:
Download and install the "Logitech Unifying Software" from the official Logitech website.
Launch the software and follow the on-screen instructions to re-pair your M510 mouse to the receiver. This reconnects the two devices, often fixing intermittent connectivity loss.
Part III: System and Settings Troubleshooting
If the issue persists, Windows settings or interference may be the cause.
Method 1: Check Mouse Acceleration (Pointer Precision)
Windows settings can sometimes interfere with the raw input signal from the M510, leading to erratic or slow movement.
Press Windows Key + R, type "main.cpl", and press Enter to open Mouse Properties.
Go to the "Pointer Options" tab.
Uncheck the box next to "Enhance pointer precision". (This is Windows' form of mouse acceleration, which many users prefer to keep disabled).
Click "Apply" and "OK".
Method 2: Check for Interference
Since the M510 operates on the 2.4 GHz frequency, nearby devices can cause interference.
Move Devices: Move the Unifying Receiver closer to the mouse (e.g., use a USB extension cable) and away from large metal objects, speakers, or other wireless devices (like cordless phones or routers).
Check Surfaces: Ensure the mouse pad or surface is clean, uniform, and non-reflective, as highly glossy or reflective surfaces can interfere with the optical sensor.
Conclusion
A malfunctioning Logitech M510 mouse is usually a sign of a fixable software or connectivity glitch. The most reliable way to restore performance is by using Driver Sentry to ensure all necessary system and peripheral drivers are stable. By combining this with replacing the batteries and re-pairing the receiver, you can quickly resolve responsiveness and connectivity issues and return to smooth wireless operation.
