Suspending immediately after boot.
I've just replaced the upper case cable, following the guide on the site.
The replacement went fine and now the computer recognises the power button the keyboard and the trackpad.
Unfortunately it seems that i've done something wrong since the laptop suspends immediately after boot.
I can always wake it up after the suspend but it will re-suspend after few secs.
When i wake-up the computer I can see that the login screen is properly loaded but I don't enough time to try to login.
It seems like the laptop believes that it has to stay always in suspend mode. Anyone has an idea of which could be the cause?
