There seems to be some kind of conflict between the Wacom Tablet Driver and OSX Lion (10.7) – The Wacom Tablet Driver (listed as pentabletdriver in activity monitor) seems to be using up CPU cycles (or something). I was being estimated 3:40 hours on a full charge with no apps running – after “killing”, or ending the process for pentabletdriver, I am now being estimated 6:40 hours with a few applications open… back in business!


So, if you’re suffering from reduced battery life after having upgraded to Lion – try killing the pentabletdriver process!
