Indeed. My usual interpretation is

- no news are bad news
- good news are bad news, we just don't know it yet
- bad news are really bad news

Unfortunately, this still makes me an optimist :-(

So do I, but the missing link in the red LED story makes me a bit
suspicious about his source.

Great idea ! On a GTA02v6, the ~5mA show quite nicely.

root at om-gta02:~# while sleep 10; do cat /sys/devices/platform/bq27000-battery.0/power_supply/bat/current_now; done

While, in another session, I did:

root at om-gta02:~# echo 1 > /sys/devices/platform/gta02-led.0/leds/gta02-aux\:red/brightness 
root at om-gta02:~# echo 0 > /sys/devices/platform/gta02-led.0/leds/gta02-aux\:red/brightness
