Very helpful article. Took me about 1 hour to complete battery replacement. Comments about persevering are helpful. Would be even better if the pics of the ribbon cable connection points were MUCH larger. The plastic separator tools are completely useless in every respect, I had to use small metal screw drivers, scalpel blades and strips of thin metal cut from a beer can (read that last one in other feedback- good advice). Anyway thanks again, all sorted and couldn't have done it without u.
