    Hello,

    I have a 15" 2010 MacBook Pro I'm using with a mini DisplayPort to VGA adapter to connect to an external display.

    It's been a while since I connected any display but today it's been acting really oddly because it will disconnect (and reconnect sometimes) the external display when:

    -I apply a bit of pressure below or to the left of the keyboard or pretty much anywhere on the Mac
    -When I hit my beloved laptop (not too hard though, of cooooouuuuuurse)

    I don't suspect the problem is related to the adapter or the VGA cable because I tried it with a 2013 MacBook Air and everything was working perfectly.

    Any idea what's wrong and what I can do?

    Well I don't have a lot of them hanging around.. (only 1, actually)

    LOL I FIXED IT!

    I put a post it right over the mini displayport adapter over the motherboard and it seems to have fixed it for real... May fix some other problems I had too...

    Thanks though!

    It may still be the adapter, but could also be an issue with your computer's port. I'd do some extensive testing with another machine and/or another adapter before making too many big decisions.

    Also, what brand of adapter is it?

    I'm not sure what you mean - although, in my mind, I see a folded up piece of paper (a Post-it note?) jammed in with the adapter plug, to keep it from moving. Do I have the right idea?

    Either your adapter is slightly bent, or worn loose, or the internal mDP socket is wearing out. A different adapter may fit better, and that's why I recommended that. The folded paper trick may turn out to be short-lived, so I still think your should consider a new adapter...

    The Apple MDP to VGA

    ----------

    I actually put the post in in the case between the motherboard and the aluminium cover...
