    MBP display going blank while encoding...

    Hi,

    While encoding long items on my macbook pro; if I don't keep moving the trackpad every so often, once the display goes to sleep, it won't come back on. This is after encoding for about 2 or more hours. It seems its still working, as the fan is still spinning, but the light on the front is on also....not sure why....

    Any ideas? If I set the display not to sleep, it may make a difference, but I want it to sleep after a while when I'm not encoding, so seems pointless to keep switching.

    I have to hold the power button in to turn it off then back on again. The whole laptop does get luke warm by this time also.

    Could I be pushing it too far..... surely the laptop can cope going full tilt for a few hours....bad design otherwise? Anyone else do video encoding on their mbp's?

    Sounds like a driver issue. My laptop has been going 8 hours a day ripping my dvd collection. the macbook should do the same with no issues. Either driver or hardware issue, but it should definitely be able to handle the load.

    Agreed, but it is quite possible it is OSX's over enthusiastic power management gone awry again, try disabling sleep and see if that does work .. it will atleast give us a starting point

    Will try it tomorrow and see. When its not doing encoding (i use handbrake and/or redux encoder) its ok; when the display goes off, it comes back at the first press, so not sure what happens and what makes it different..... very strange.

    Will let you know.

    When computer and display mode are set to never, the laptop encodes fine and doesn't go off. Funny thing is that the laptop was always set not to sleep, only the display was set to sleep after 15 mins.....

    Strange, but at least my encoding got done. Will be re-doing snow leopard at xmas time so hopefully this issue will go away then.
