I've just tested this feature on my 41c and 41cx Halfnut and - lo and behold - the older 41c switched itself off after 10 minutes, while the 41cx had been gone dark after around half of the time already. Could this be a common behaviour with the newer architecture?

Just for full disclosure: My 41c was powered from Alkalines and the 41cx from NiMH-cells, although I don't think that this should be relevant for the auto shut-off time.
