Powerbook g4 sleep problem

Okay im having a problem with my powerbook g4 15in 1.67ghz recently I have replaced the top cover tht can be removed to access the logic board and other comments of the powerbook. But after I had replaced tht cover the computer has not been able to go to sleep when the display is closed and you have to put to sleep by click the apple logo and then sleep also when you open the display of the laptop it does not automatically wake up you have to press the space bar to wake it up. Note I took the top cover from another powerbook g4 tht was an 15in an was 1.67 ghz.

MacBook Pro, Mac OS X (10.7.2)

There is a sleep switch that may have been compromised during reassembly.

The magnet must activate a sensor (switch) which would be opposite in position within the lower case. It may be part of a board or in some PowerBooks a separate part and could have been disturbed when reassembling. 🙂
