I confirm that this bug is fixed. I have an older HP Elitebook 8530W.
But I had the same issue. It's fixed in Ubuntu 12.04.3 LTS and newer

Title:
  8086:4238 [HP EliteBook 8540w] wifi led indicator blinks

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I do not know if it makes any harm, but after connecting to wifi
  accesspoint the wifi led indicator blinks (red-blue) instead of having
  instant blue. When it is disabled it is constant red. Under Windows it
  is blue all the time when connected.

  The following lines about wifi can be found in dmesg:
