Description

On a ThinkPad X200, with coreboot revision 4.4-910-g168eb6a, the Bluetooth light has never turned on, despite active Bluetooth usage. Which are the files that handle the Bluetooth (and possibly WiFi and WAN) light(s)?

I have two X200s and the light seems to work fine in ArchLinux (can't say about traffic, but it goes on/off with the kill switch).

What's you're operating system?

#73 is possibly a duplicate of this.

Can you check if the nvram option uwb has any influence on your bluetooth light?

USE_OPTION_TABLE enabled and uwb disabled results in the light working as intended, and flashing on traffic. Enabling uwb disables the light.

Can somebody test if this works as expected with vendor BIOS? Would be easier to fix then. We could probably find out how the vendor BIOS does it.

When I was still using the X200 (before I librebooted it), I definitely
had all of the ports turned on. (As I remember trying to get the weird
Intel SSD to work in Linux)

I'll see if I have a backup for my spare X200 still, but the problem
with testing is that the Lenovo BIOS has a whitelist, so I won't be able
to actually ensure that the port is enabled.
