MBP Bottom Case Slight Flex???

    First, I have made sure that the two retaining clips are engaged! Second, I understand that the bottom case is made out of thin aluminum and logically should slightly flex under pressure...

    I'm curious though, how widespread is this and should I be concerned? I know that the inside of the bottom panel is insulated, so in the chance that the bottom case does make direct contact with the logic board, nothing will short out.

    However, I am trying to figure out if what I am experiencing is "within normal tolerances/specifications." I'm sure everything is OKAY... I'm just going through another one of my "OMG! Is something wrong with my MBP"-Phases

    lol

    It seems to be more pronounced directly over the logic board. Is this a problem??? It almost seems like if I apply enough concentrated pressure the bottom case would touch the logic board...

    You realize on a 15" that its about 10"x15" of unsupported aluminum that is probably only .08" thick...

    Well, does your exhibit the same type of behavior?

    I know exactly how "thick" the bottom case is... I have examined it removed from the upper case before. Yea, it's ridiculously thin...

    it's fine quit worrying and use the computer instead of examining it ;)

    until there's a problem, don't freak out. if you're feeling paranoid then back it up once a day.

    From an engineering standpoint and the fact the aluminum becomes exponentially weaker as it gets increasingly thinner, I'm almost positive that some flexing of the bottom case is normal. There really is no other explanation...

    And it's obvious from the design of the bottom case that it was probably designed with this factor in mind... The underside is coated with plastic to prevent shorting out the logic board, for example...
