In Gemian the component that does the LED work is:
https://github.com/gemian/gemian-leds
Its currently configured to show:
Internal LED - red for caps
Eternal far right LED -
* Blue - bluetooth is on
* Green - wifi is on
* Red - cellular is on
* White - all are on
* Mixes - as per mix etc.
They are set at brightness 1 out of 3, which is the minimum, there is some work ongoing to get a better control of the LED's when we'll bring the brightness down and balance them so that the mixes are not so dominated by the green (which is to my eyes brightest of the three colour options).
Uncertain what LED's your referring to, suspect it might be the above. Personally I wanted to know easily with the device closed that I'd left WiFi on as I find that with it off for an 8h sleep it'll drop 2-4% battery, and with WiFi on it'll drop 35-45%.
Work in progress, patches welcome.
Thanks for the Info Adam, especially about the wifi drain.
The Wifi
was on, so that would explain the green light, but the Bluetooth should have been off, so i don't know why the blue light would have been on.
I'm going to check again in the settings to make sure.
edit : OK. I hadn't rebooted or closed the connection manager when I switched of the Bluetooth, and it hard locked on me at one point and I forced it to switch off. The Bluetooth then switched back on, at boot, as that was its previous state. Glad I can have all the LED's off at night, as you say, just have to remember to cut the Wifi connection.
