Step 1: Rule Out Software Issues

Before opening any hardware, confirm that the problem isn’t caused by a driver or system error.

• Check your Device Manager and update the keyboard driver.
• Use an on-screen keyboard to test if the volume can be increased through software.
• Confirm volume control settings in Control Panel > Sound.

For deeper steps, refer to Microsoft’s official keyboard troubleshooting guide.

Step 2: Clean the Volume Key

Dust and dirt often interfere with key contact:

• Turn off your device
• Blow compressed air around the volume key
• If removable, gently lift the keycap and clean the area with a dry cotton swab or soft brush

Refer to your device’s repair manual for safe keycap removal.

Step 3: Remap the Volume Up Function

If the physical key is broken but the keyboard still works, remapping the function is a quick fix. You can assign the volume up action to a different key using tools like:

• SharpKeys – A reliable, open-source key remapping utility

This allows you to use an alternate key (e.g., F9 or another unused key) for volume control.

Step 4: Inspect and Repair the Key Mechanism

If cleaning and remapping don’t work, the key mechanism may be damaged. Depending on your device:

• For external keyboards: Open the casing and check for broken contacts or worn circuitry

If the internal hardware is faulty, replacing the keyboard or the top panel may be necessary.

Conclusion

A non-functioning volume up button can usually be fixed with basic cleaning, software tools, or key remapping. If the issue is hardware-related, resources like iFixit can guide you through a safe repair or replacement process.
