Hi, I have been attempting to open up my AA1 to upgrade the RAM, but have found that the screws in the battery compartment are [i]extremely[/i] stiff, to the point where I have so far been unable to remove them. At this point the screw heads are beginning to be damaged by the effort and I really don't want to strip them completely. I have tried a few different screwdrivers, but the screwdrivers that get the best "lock" into the screw are of the thin, "Jeweller's" type which I can't get enough leverage on to turn. Does anybody have any useful tips or advice for removing these stubborn screws?
