This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Yesterday I noticed a slight bulge at the bottom of my 39 month old 13" Mac Book White. Coconut battery tells me I got 4216/5450 capacity, battery load cycles 581.
Besides the bulge, I do not see any other problems, visually as well as in performance.
Is it time for a battery change?
