MAC BOOK PRO; battery life
Battery life was becoming too short. The batteries exhausted after only 1,5 movies on the plane..
In the beginning my MAC could do a full day's work on a charge.
Hope to return to these good numbers again.
It was very simple following the excellent guide.
Although, nervous prying the battery loose knowing the possible risk of dammage/fire.
I used a plastic putty knife to pry the battery to get a wider area of attack.
I could then also pry more powerful with a screwdriver between chassi and the putty knife.
