Comment(by rsmith):

 Replying to [ticket:10357 wad]:
 > Using Q3A54 on an XO-1.5 laptop, the power LED blinks for too long.
 >
 > I suggest that the power LED only blink while the SD power is being
 delayed...

 Thats exactly the current behavior.  The power LED blinks for the duration
 of the time that VR_ON is held up after the other signals are de-asserted.
 Approx 3 seconds.

 If you want it shorter then the blinks either need to start later or we
 need to decrease the VR_ON holdup time.
