disk activity lights can be pretty keen when you're trying to figure out whether or not the system is entirely halted or just slogging through a heavy workload.

the kind of time when a tool that is good at measuring such things won't ever even attempt to load.

Yes. Related, I really do not need my headset to blink in the eyes of the person I sleep next to this hard. Why does it blinks seven times every time I use any command like volume up and down?

So thick black tape it is. (Can't do anything about this voice screaming the headset's status though.)

LEDs that are too bright on my laptops get similar treatment. I try to leave them a bit visible, enough to see in a dark room whether they are on, but the laptop not sending light including when it's suspended is more important.

> when there's a lot better tools to measure disk or network usage anyway.

Only if your system is working fine.

Only if you are okay with switching the context.

'Flashing lights' aren't the best troubleshooting tools, but they are OOB and works constantly. Frantically flashing HDD LED would say you about why the system froze for a couple of seconds way sooner when you oculd launch some performance monitor things.

monitoring the presence of disk and network activity in general was a lot more useful when computers only did things when you told them to and only made connections to remote hosts when you explicitly requested it. Never knowing what your devices are doing or who/what they are communicating with without having to launch a full scale investigation was nice.

Why would the disk activity or "power on" lights be "on" if "everything is "off"" though
