May 2006 2.0 Core Duo, First Gen MBP The latch shuts properly, and it holds the lid shut properly. It opens, but it doesn't "pop" open like it once used to. You have to pull up on lid when pushing the button to get it open. I mean, it's not a huge issue, and if you never knew it was supposed to pop, you probably wouldn't know. It's just kind of irritating, any ideas? I've already tried cleaning everything latch related out.
