I've come to the conclusion that it's an hardware problem. In case of Sony Vaio there are many reports (like http://club.vaio.sony.co.uk/clubvaio/gb/en/forum/viewthread?thread=43230&offset=0 or http://forum.notebookreview.com/showthread.php?t=282258 ), and the new kernel didn't change anything. Probably an hardware short is draining the battery.
