When running an external display on a MBP...

Is it safe for the lid to remain closed while the system is on? By that I mean, will there be any issues with heat damaging the lid and/or screen? I'd like to simply leave the lid open, but I don't want anything showing on the MBP's screen while I'm working on my external LCD, unless of course there's a setting I missed while setting it up.

Of course, if it's safe to run the system with the lid closed with no risk of long-term damage, then no big deal.

 

I think I actually read about that MBs/MBPs are officially "ok" to be run closed. But I really like to hear someone of the more experienced ppl here say a word about that... So, yes, I´m interested in it, too.

 

I went ahead and called Apple, and the tech basically told me that the MBP is designed to run that way. Since the case also acts like a giant heatsink, the system will get warm, but it should be no big deal as long as it's not getting super hot.

If anyone has any thoughts to the contrary, please post them.

 

Ah, very nice, so I recalled correctly. You haven´t heard any word about this applying to the MBs, too, have you?

 

Plastics are more like a heat trap than a heatsink..........

however the LCD wont be the thing to get damaged. Most likely the heat will make the system unstable before anything actually gets damaged.
