If the small screw/battery tabs (which hold the battery in place) are broken, is this always indicative the laptop has been dropped? We have a few MacBook Pros which have some minor problems, but upon opening the case we find the small screw tabs have broken off. For us, this is the difference between processing the repair as an insurance claim (for accidental damage) or repairing in house. There are no dents or any other signs of damage or abuse - just the broken tabs.
