sleep wake up

[skd]

I have a 17" MBP and 30" ACD -
I'll put the MBP to sleep - closing the lid -
when an email is received while in the sleep mode the external monitor comes back on. Is there a way to keep this from happening.
thanks

I may be mistaken, but I don't think it is going to sleep if it is receiving email. I do know that when an external monitor is plugged in, it will not enter sleep mode when closing the lid. I'm not sure where to change that though.

Unplug your external monitor before closing the lid.

I don't see how that's possible. If its actually sleeping it shouldn't be receiving email.

Regardless, when I put my MacBook to sleep, I unplug the MagSafe connector. This prevents it from waking up for anything.
