Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
I wanted to use the power LED on this laptop for HDD activity, saw triggers can do this...
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I tried to first check if the kernel can control the led, outputting max_brightness to the brightness file worked
outputting 0 to it also worked to turn it off, so with this I assume the kernel has proper support for controlling the LED
I also tried modprobe-ing "ledtrig-activity" for another trigger
   * What was the outcome of this action?
Controlling the LED works, other triggers do too, and the kernel CAN control the LED, but using "disk-activity" or "disk-read" as triggers did not
   * What outcome did you expect instead?
I expected the LED in question to blink in HDD activity.
