Razer DeathAdder V3 Pro Scroll Wheel Not Responding to Input

If the scroll wheel on your Razer DeathAdder V3 Pro jumps erratically without input or does not respond to scrolling, then follow these steps to diagnose and fix the issue.

Built-up debris around your mouse inhibits its proper function. If you notice any build-up around the scroll wheel, use the following steps to clean your device:

• Disconnect the mouse and make sure the power is off.
• Use a swab and alcohol to clean around the scroll wheel area to clean solid buildup.
• Use compressed air to clean dust buildup.

The device's firmware being out of date can result in issues with the scroll wheel's response.

• Ensure that the device's firmware is up to date.
• Update firmware if a new version is available.
