MacBook thinks the lid is closed and goes to sleep, why?
Today's magical mystery: MacBook goes into sleep on logon.
When I start the machine up with the top case unsecured, and a small gap between the top case and the bottom case, it works normally. It doesn't go to sleep.
As far as I understand the sleep switch is triggered by the magnets in the lid.
Could there be something in the top case that's magnetic and triggering the switch?
The top case is clearly not the original one - it's a late 2007 machine with a 2006 top case (the first version with the golden twisty cable).
Ideas appreciated, thanks ;)
Is this a good question?
