How to stop MBP from shutting down during night (when necesscary)?

[amgine516]

Hi I've got on of the first unibody MBP15".

My problem is that sometimes i have to leave it on during night when doing renderings for school. I think that I've tried everything to stop it from trying to shut down. Still just this morning it had the rendering stopped and wanted me to confirm a shutdown.

I've tried the energy savings settings and such and I've tried searching various forums including this one - no luck.

Hope you guys (/girls) can help me!

Just checking, you leave it plugged in over night right? You can always try a program like InsomniaX. It prevents the computer from falling asleep, even if it is closed.

Try a program called Caffeine

change the Energy Saver settings??

My energy saver settings are set to never sleep on both AC and battery.

It puzzles me that it's necessary to download a 3rd party app to do what osx should be able to do.

Thanks for the proposals

Are you sure the screen is not cutting off? If you move the mouse does it turn back on?

It is just turning the screen off if moving the mouse turns it back on.
