Ferrari charger

[Giorginetto]

I got this ferrari charger about a couple of months as I am not using the 575 as often as I wished and is indeed a Garage Queen for a good 9 months a year or so. Regardless of this, i got the original FErrari Charger that comes in this hard leather case and been using it. Last week when i poped in the garage it was turned off and i had to turn it back on... Has anyone had that problem? I knwo for a fact that it wasnt turned off my me as i had checked the car only a couple of days before and it was fine. no one else entered the garage . is that a common fault with this charger ?
