Dismantling 2 identical laptops [to exchange parts] and had no problem with one set of 4 phillips switch cover screws "PM2.0×2.0" but the 2nd lot, absolutely no go. Obviously they may just have been put in far tighter than the first lot but although they're identical the same screwdriver seems to not even feel like such a good fit before you even start attempting to turn.. illogically. Any point at all in acquiring new/better screwdrivers (I'm not all that well off in that line, which I should be) or do I just have to assume it'll be a more challenging removal job regardless of kit? Ta much if you can help.
