    Well, it does shut off, but not for a few seconds (must be a failsafe built in).

    I dropped one on a tile floor last night and saw the light come on and thought "hmm.. was that my auto?" Nope, it was a manual.

    Now when I press the button it turns on but won't shut off when I release and will shut off after about 5 seconds.

    Any idea on how to fix this? Kinda stinks. :)

    I dropped an auto and it responded by not shutting off until the cut off time was reached every time I took a drag. Then I would have to wait through the time out to use it again. Eventually I put it in my little bag of dysfunctional batteries due to frustration. I don't know of any way to fix this once it has occurred. :(

    You should be able to9 shut it manually by blowing back after you pull the puff, or if you wait to the autoshut, then you can start again by blowing a bit and then pulling air - at least thats what I do with one of mine that had this since beginning. Just to clarify its an KR808D-1, not M401, I am guessing the idea should work too.

    401 is microphonic ( sound activated), KR808's are suction switch. Totally different.

    I lost 2 manual 401's.. 1 to dropping , 1 to leaky juice *oops*
    I recovered one of them by popping the button out and checking that everything was seated well and gave both a cleaning by using a papertowel rolled up and going through the button hole.
    I figured at that point, nothing to lose anyway lmao

    Wench, any advice how to open the battery? I have one manual 401 that gives permanent power to the contacts (it was working perfectly before) but it doesn't power the atty. I want to open it up with a chance to close it afterward... :rolleyes:
