I realize laptop manufacturers inflate battery life, but I'm only getting 2.5 hours on my Toshiba Satellite M645-S4045 - they advertise the life at 5 hours. Is this common? - or is it something that I need to contact Toshiba support? I got it from Amazon - I'd hate to go through the hassle of getting it replaced, but there is still time.
Advice?
