Involuntary Reboot #4 – Trackpad Issues Again

Fourth time. I open my MacBook Pro to wake it up. Mouse behaves erratically like it is on crack. Same symptoms as before.

I let my MacBook Pro sleep and then wake it up. Hope that the problem is gone. It got worse: both the keyboard and trackpad are not working now.

After connecting an external keyboard I was able to get this from the system log:

AppleUSBHub::setPowerState(0x68fd800, 2 -> 4) timed out after 10617 ms

Maybe some smarties in Cupertino should fix this. It looks like a software problem.

Leopard is like Windows. A reboot each day. So incredibly lame.
