Comprehensive Guide: How to Test Mouse Button Functions, Scroll Wheel Performance & Common Troubleshooting

Tool Introduction

This online mouse testing tool is designed to help users quickly detect whether all mouse functions are working properly, without installing any software. Through visual interface and real-time data feedback, you can fully understand your mouse's working status.

The tool supports testing: left button, right button, middle button, two side buttons (B4/B5), scroll wheel up/down functions, and has double-click detection capability.

Enter Test Area

Move your mouse into the "Mouse Test Area". When the mouse enters this area, the border will turn blue and the status will display as "Active".

Important Note: Testing functions are only effective within the test area. Make sure your mouse is completely inside the gray border area.

Test Area Status Indicators

Border color changes reflect current test status:

  • Gray: Ready status
  • Blue: Active status
  • Light Blue: Testing in progress
  • Green: Double-click detection
  • Red: Fault detected

Test Mouse Buttons

Within the test area, click each mouse button separately:

Left Button Test

Click the left mouse button. Observe if the left "Left Button" area lights up, and the "Left Button" count in the right data panel increases.

Right Button Test

Click the right mouse button. Observe if the right "Right Button" area lights up, and the "Right Button" count in the right data panel increases.

Middle Button Test

Press the mouse wheel (middle button). Observe if the middle scroll wheel area lights up, and the "Middle Button" count in the right data panel increases.

Testing Key Points: Each button should have clear press and release feedback. For normal buttons, the "Press" and "Release" counts should be equal.

Test Side Buttons and Scroll Wheel

Continue testing other mouse functions:

Scroll Wheel Test

Scroll the mouse wheel up and down. Observe if the up/down arrows in the "Scroll Wheel" area flash, and the "Scroll Up" and "Scroll Down" counts in the right data panel increase.

Side Button Test

Press the two side buttons on the left side of the mouse (usually labeled B4 and B5). Observe if the B4/B5 area on the left lights up, and the corresponding counts in the right data panel increase.

Note: Some mouse side buttons may require driver installation to work properly, but basic button functions should be detectable.

Double-Click Detection Test

Double-click detection is an important feature of this tool, used to identify whether mouse micro switches are aging:

Normal Double-Click

Double-click the left mouse button at normal speed (interval 200-500ms). If normal double-click is detected, the button area will show green highlight, and "Normal Double-Click" will be recorded in the log.

Faulty Double-Click

Try rapid consecutive clicks of the left mouse button (interval less than 80ms). If faulty double-click is detected, the button area will show red highlight, and "Faulty Double-Click" will be recorded in the log.

Diagnostic Significance: Frequent occurrence of faulty double-clicks usually indicates mouse micro switch aging, possibly requiring cleaning or replacement.

Interpret Test Results

After testing, determine mouse status based on information in the right data panel:

Normal Status

All buttons have equal "Press" and "Release" counts, scroll wheel responds in both directions, double-click detection shows normal intervals.

Abnormal Status

Some button count doesn't increase, press/release counts don't match, scroll wheel doesn't respond in one direction, frequent faulty double-clicks.

Event Log: The event log at the bottom right records timestamps and detailed information of all operations, helping you review the testing process.

Reset Function: Click the "Reset All Data" button to clear all counts and logs, starting a new test.

Common Issues & Troubleshooting

Issue: Buttons Not Responding

Possible Causes: 1) Mouse not connected or poor connection; 2) Test area not activated; 3) Physical button damage.

Solutions: Check USB connection, ensure mouse enters test area, try testing the button in other software.

Issue: Scroll Wheel Not Responding

Possible Causes: 1) Scroll wheel encoder failure; 2) Browser compatibility issues; 3) System mouse settings abnormal.

Solutions: Try scrolling on other pages, check if browser supports wheel events, adjust system mouse wheel settings.

Issue: Frequent Faulty Double-Clicks

Possible Causes: Mouse micro switches aging or poor contact, a common hardware failure in mice.

Solutions: Clean mouse micro switches, adjust double-click speed settings, or consider replacing the mouse.

Issue: Side Buttons Not Detected

Possible Causes: 1) Mouse driver installation required; 2) Browser doesn't support side button events; 3) Side button functions disabled.

Solutions: Install official mouse drivers, try different browsers, check side button settings in mouse software.
