Macbook Pro users with an external monitor
I'm having a problem where after about 20 mins or so of the machine shutting off the screens while it renders, I can not turn the screens back on unless I close the Macbook top, re-open it, and then press a key or the touch pad. Touching the pad or a key prior to doing that does not work.
If it shuts off after 5 - 10 mins, it will turn back on no problem, but after about 20 is when this happens.
Is this normal or is there a setting somewhere to adjust this?
Thanks.
