F6 mute button light not working after latest Windows update Hi, I have a HP laptop and the F6 mute button light is no longer working after the latest Windows 10 update. If you need more, let me know I'll post back asap. They worked on Windows 8.1 before I upgraded to windows 10.

Until Lenovo will address that issue, which it probably will not because of the age of the T400, the sound will not work from the speakers. Original Title: Mute ICON One of my keys on my keyboard is a speaker mute with a tiny led that lights up when the key is presses indicating the speaker is muted. All of the buttons at the top of my keyboard (ESC,F9,F10,F11) don't work such as the brightness buttons, mute button, etc. Everything else works fine, I just can't get these *** sound buttons to work. The Power button light (green) will blink to show when mute is on; The Mic mute button light (orange) will be on or off to show mute status (just like in Windows) Solution 2 requires a patched thinkpad_acpi kernel module, and is only recommended for advanced users who know what they are doing. Any ideas? Okay so basically I pressed the mute button on my mum s laptop earlier and it s ******* stuck now, she s pissed please help me It s the mute button on the keyboard the little white light is on ad when I press it on the screen it says it s unmuted but really it isn t and the light stays on My sound works fine. yesterday evening I pushed the mute button of my Thinkpad x230, with openSuse Leap now the sound is muted and does not come back, reboot let the mute button light, so it knows it is muted, but I can not unmute the system anymore this is a strange problem, considering the fact that I also have a Thinkpad T420s with Slackware 14.1 Thanks, Toasty. To resolve this issue, download and install an updated audio driver using one of the methods described below. Problem is, my Thinkpad's volume buttons don't seem to work. I have been looking and trying some of the YouTube fixes, but have not found one to fix mine. I … Thinkpad X200 FTW! I installed the tpb package and now my mute button works, but the volume up and down don't. The mute button does not work properly on most ThinkPads and IdeaPads with a newer kernel. Anyway, bluetooth works, and I have a fine speaker that works. I don't know if Mute button stuck on Lenovo Thinkpad, please help? However since I was a bad boy and upgraded from windows 7 to windows 10 THe mute key icon stays on all the time whether the speaker is muted or not. I've had the computer for less than a month. Mute for speakers does work. (its just the light, the mute function still works) Hp have no idea how to fix it. I have the microphone working on my T520, but the Mute button does nothing. Thanks for the information, but I already tried that, still no luck. Understanding the problems with the Audio Mute Button and Task Bar Mute The audio mute button and task bar icon mute button are not functioning, but the HP Quick Launch buttons are working correctly. My F1- Mute, F2-Sound Decrease, and F3-Sound Increase buttons won't work on my new Dell™ Inspiron 15 Laptop Computer i5559-4013SLV. Two different scenarios occur: Nothing works. The Button does not react at all: no led flash (some ThinkPads have an LED, indicating the Mute-State) and no effect on Speakers Volume. It seems to have something to do with the mute button on the keyboard itself.
