Hi, untill now, my battery on my late 08 MBP was fine (around 4h). Yesterday, I tried to switch for the 1st time to the 9600 and then back again to the 9400. I have the impression that something wrong happened cos now I get only 2h of battery on the 9400 with low contrast, surfing only. With a full battery, the estimated time is 2.20h, before it was estimated around 4-5h what the hell is going on ? Battery heath seems to be ok. Can it be only the estimation bug ? I'm measuring it right now how long it will last.
