MacBook 1,1 won't wake up when Lid is opened

today i changed the complete lid from a MacBook and now the MacBook won't wake up when the lid is opened - sleeping is no problem - the book falls asleep as soon as the lid is around 1" away from the battery connector/sleep switch - wut when i open it - nothing, i hav to press a button and then it comes back to life.

i used a magnet to test the switch - works without a problem - but the "point" is a little bit off - when i use the point where the magnet is in the lid - it only wakes up with a stronger magnet.

my ptoblem with that is only one thing - the both points are non changeable - can the magnet in the lid be "to weak"
