matt tav for your stuck latch, try the solution “On the side of the battery facing the trackpad there are 3 prongs with diagonal tabs next to them. These prongs mate to 3 catches on battery compartment which ought to slide with the battery release latch. In my situation 2 of the 3 sliding prongs had been jammed down and their tips caught on the base of the laptop. This prevented the prongs from contacting the diagonal tabs on the battery and sliding to catch the battery's prongs. All I needed to do was take a small screwdriver and pry the tips up so they and the release button were free to move again. It's probably worth noting that no covers or screws need to be removed to do this. “ from [link|https://h30434.www3.hp.com/t5/Notebook-Software-and-How-To-Questions/HP-G62-355DX-Battery-latch-won-t-move/td-p/1009081|here]
