Fix Unresponsive Buttons or Scroll Wheel on G305 Mouse

The LIGHTSPEED G305 Wireless Gaming Mouse by Logitech is a favorite among gamers and productivity enthusiasts alike, known for its ultra-fast response time, high-precision HERO sensor, and durable wireless design. But even high-quality peripherals can sometimes develop issues. One common problem reported by users is unresponsive buttons or a malfunctioning scroll wheel, which can severely hinder your gaming or work experience.

In this comprehensive guide, we will walk through the most effective troubleshooting techniques to fix these issues and restore full functionality to your G305.

Overview of the G305 Mouse

The LIGHTSPEED G305 Wireless Gaming Mouse is built with Logitech’s proprietary LIGHTSPEED technology, offering wired-level performance over a wireless connection. Key features include:

  • HERO sensor: Up to 12,000 DPI

  • LIGHTSPEED wireless: 1ms response time

  • Ultra-low latency

  • Compact, portable design

  • 250 hours of battery life with a single AA

Despite its reliability, users sometimes experience problems like unresponsive left/right clicks or a scroll wheel that doesn’t work smoothly.

Common Issues with Buttons and Scroll Wheel

Before diving into troubleshooting, let’s look at the most reported issues:

  • Left or right mouse button not responding

  • Double-click registering as a single click

  • Scroll wheel not scrolling or scrolling inconsistently

  • Side buttons becoming unresponsive

  • Clicks feeling “soft” or delayed

These can be caused by hardware wear, software conflicts, firmware issues, or even dirt and dust buildup inside the device.

Initial Checks Before Troubleshooting

Before proceeding with complex fixes, try these simple checks:

A. Test on Another Device

Plug the receiver into a different computer. If the mouse works fine there, the problem might be with your system’s USB port or software.

B. Replace the Battery

Low battery can cause performance issues. Replace with a new AA battery and ensure it’s inserted correctly.

C. Use USB Extender

Keep the receiver close to the mouse. A USB extension cable can reduce signal interference from other wireless devices.

D. Update Logitech G HUB

Ensure that your Logitech G HUB software is up to date. This software controls key bindings, DPI settings, and firmware updates.

Step-by-Step Troubleshooting Guide

Step 1: Clean the Mouse

Dirt, grime, or dust can physically block button mechanisms or scroll wheel sensors.

How to clean:

  • Power off the mouse and remove the battery.

  • Use compressed air to blow out debris around buttons and the scroll wheel.

  • Gently use a soft brush or cotton swab to clean crevices.

  • Use isopropyl alcohol (90% or higher) on a microfiber cloth for deeper cleaning (do not oversaturate).

Step 2: Check for Firmware Updates

Outdated firmware can result in erratic behavior.

To update:

  1. Open Logitech G HUB.

  2. Click on the G305 icon.

  3. Navigate to “Settings.”

  4. Check for firmware updates and apply if available.

  5. Reboot the mouse.

Step 3: Re-Pair the Device

If the connection is unstable, unpair and re-pair the mouse.

  1. Unplug the USB receiver.

  2. Turn off the G305.

  3. Plug the receiver back in and turn the mouse back on.

  4. In Logitech G HUB, ensure it is detected.

  5. If not, try a different USB port.

Step 4: Reset G305 to Default Settings

Sometimes, a bad profile or macro configuration causes input issues.

  1. Open G HUB.

  2. Navigate to onboard memory.

  3. Remove custom profiles and use the default profile.

  4. Test each button and scroll function.

Step 5: Reassign Buttons

If a button appears to be dead but the hardware is fine, it could be a software mapping issue.

  1. Go to Logitech G HUB > Assignments.

  2. Check if the button is assigned correctly.

  3. Reassign if necessary to the default click/command.

Advanced Fixes for Persistent Problems

A. Use a Different Profile

Sometimes the active profile may be corrupted or misconfigured. Switch to a different profile in Logitech G HUB.

B. Test with Diagnostic Tools

Use third-party diagnostic tools like “MouseTester” or “AquaKeyTest” to verify if clicks are being registered.

C. Reinstall Logitech G HUB

  1. Uninstall Logitech G HUB completely.

  2. Restart your system.

  3. Download the latest version from Logitech’s official website.

  4. Reconnect the G305 and test again.

D. Open and Repair Internally (Advanced Users Only)

If the button or scroll mechanism is physically worn out:

  • Open the mouse using a precision screwdriver.

  • Inspect for worn-out switches (usually Omron switches).

  • Replace with a compatible micro-switch.

  • Reassemble carefully.

⚠️ Note: This voids your warranty and is recommended only if you’re experienced with electronics.

Maintenance Tips to Prevent Future Issues

  • Keep your desk clean: Dust can easily get into the scroll wheel or button seams.

  • Store in a case: When transporting, protect the mouse from impacts or contaminants.

  • Replace batteries proactively: Don’t wait for performance drops.

  • Regularly clean the sensor and body: This avoids buildup that could affect motion tracking or clicking.

If your LIGHTSPEED G305 Wireless Gaming Mouse is acting up with unresponsive buttons or a faulty scroll wheel, don’t panic. With the right troubleshooting steps, you can often fix the problem without needing a replacement. From software resets to physical cleaning, this guide should help you get back to peak performance quickly and efficiently.
