** Changed in: linux (Ubuntu)
Status: Confirmed => Triaged
** Summary changed:
- Bluetooth LED on Dell laptop permanently on
+ [Dell Precision M4300] Bluetooth LED permanently on
** Description changed:
When switching off bluetooth the LED used to also turn off, I re-tested
quickly with Natty to confirm this, but for at least the last two
releases the LED is stubbornly staying on all the time.
- There are two similar expired bugs #1094590 and #178872
+ I have identified the commit specific to Dell laptops that broke this
+ and quite coincidentally this same commit was just reverted on the next
+ branch only a few days ago. It's not all good however as the companion
+ commits replace a laptop blacklist with a whitelist meaning it currently
+ only works with Latitude models so I have to see if I can get Precision
+ models also included.
+
+ The commit that resulted in this issue was introduced in 3.5 kernel as
+ "dell-laptop: Remove rfkill code"[1]
+
+ I have built and tested the linux next branch code with the revert
+ commit [2] and then modify the "Latitude" product string commit [3] to
+ "Precision" and the bluetooth LED is now switching off as it should do.
