Num lock and Mute lights not working after Windows 10 Spring Creators Update (HP Pavilion 17-G121WM)

[KatKane]

I recently got a new refurb, and over the last few days I've been getting Windows 10 up to its current version. After the 2018 Spring Creators Update ran (1803) I noticed that the lights on the Num lock and Mute buttons on the computer no longer light up. I can't be sure if it happened between when I upgraded to 1709 and 1803, or only happened after the 1803 update - since that was all done within a day of each other - but I have done multiple reboots since I completed the last set of updates. 

I did a lot of research trying to find a solution, and am pretty sure the core of the problem is the HP System Event Utility. However I've also made sure I'm using the latest version of the HP System Event Utility for my laptop (1.40 Rev.A released Jul 17, 2017) and it has not resoved the issue. 

Am I stuck this way unti lthe utlility is updated to cope with the 1803 changes to Windows? 

Thanks for any help you can offer.

Hello KatKane,

Try the following steps:

1. Unplug the charger
2. Remove the battery
3. Hold down the power button for at least seconds
4. Reinsert the battery
5. Attach the AC adapter

Also boot into BIOS (F10) to at least check if the CAPS lock works there. If it doesn't, then it's a hardware issue.

Uninstalling the keyboard driver in Device Manager may help but this may just be a Windows issue.

Kind regards,

Eddy

Hard to say what in here did fix the problem. When I booted after the power-draining procedure the Mute light was still not working. And I realized at that point (after reviewing the manual again) that there actually isn't a light on the numlock key for this model - which I find strange and slightly frustrating for a laptop that has a 10-key pad.

And since the Capslock light was never my issue at all, the BIOS boot shouldn't actually have done anything - though I did perform it just in case, and within BIOS obviously the Mute button didn't light up. But strangely, after I booted back to normal Windows from the BIOS, then my Mute light came back and appears to be working normally.

So while I can't pinpoint what actually resolved it, my problem is resolved. Thx.
