Hp compaq nx9010 audio mute button and LED not working


I've been given a hp compaq nx9010 notebook computer which works perfectly except the audio mute button and LED don't work at all. The up/down buttons work fine. What could be wrong? The switch feels OK and has a good 'click'. My background is in electronics so I should be competent to fix this if it's a hardware problem. If you have any thoughts I would be very grateful! Even better could someone email me a service manual please?

    I have just wiped the hard drive and reinstalled from scratch using the
    HP operating system and drivers disc. Although I have installed all the
    hardware drivers, I must admit that I have tried not to install all of
    the system software utilities. I will check to see if I have missed
    something important. Any help appreciated.

I copied and pasted the following from I hope it helps!

Clinton Tam hp compaq nx9010 audio mute button and LED not wor - sun.gif Jan 21, 2005 13:59:29 GMT 10 pts As for the problem with Wifi LED and mute LED issues, you need to do the following:

1. Uninstall the Notebook Utilities from Add/Remove Programs.

2. Uninstall the One Touch software.

3. Reboot.

4. Reinstall One Touch Software.

5. Reboot.

6. Apparently the One Touch doesn't enable all the buttons on the ze53XX unless the Notebook Utilities software is loaded last. If the utilities are loaded first, One Touch breaks it.

Download Notebook Utilites from here and install.

7. Reboot.

I called HP. Here is what worked for me. Restart computer inbios mode. Press F10 key as it is booting up, Once in bios, select load set up defaults. Once you have done that, reinstall the drivers that apply to your sound card. Fic took no more than 5 minutes.

Hello Rich,

Hope this helps. If you can control muting on and off at Control Panel, System, Device Manager, Audio properties then you only need the utility software to activate the function keys. Please check at manufacturer's website for the keboard or similar function key utilities.

Best regards,

The ribbon cable to those quick buttons may be broken. I've seen that happen more than once. the only way to test it is to remover the battery, Take out the screws in the battery compartment that hold down the Power Strip & Quick Button strip. Flip the laptop right side up, and gently pry up the strip that has the power button and quick buttons on it. Once that's done, try wriggling the ribbon cable back & forth while a song or some other sound file is playing to see if you get sound. You do this at your own risk though. I once shorted out the power button circuit board doing this. If the Ribbon cable is bad, then you can get a replacement on Ebay.

This is a typical symptom of motherboard failure. Your laptop's motherboard will need to either be serviced or replaced.

Try both, as 9010 is built in two different versions.

Please vote the solution.
