    P2140 shutting down mac mini after about 10 minutes

    Hi folks,

    I have a mac mini installed in my jeep with the CNX-P2140. The computer stays on for about 10-20 minutes, then shuts down. The red lights are flashing on CNX-P2140 quickly. The voltage going into the CNX-P2140 seems fine, doesn't go below 13V on my voltmeters. I'm not sure what to do next. Anyone have any ideas?

    Thanks,

    Elias

    Did you verify that you have the jumpers set correctly for the Mac Mini?

    I thought I did.
    JP1 set to 18.5V
    JP2 set to 12V
    JP3 set to all open
    JP4 not sure what this is for
    JP5 set to Mac Mini Intel
    JP6 closed

    Does that sound right?

    I am connected to liliput monitor as well

    I just installed temperature monitor, I think all are in range (under 60 degrees C) I'm not sure what else to check.

    Figured out the problem - overheating

    Hi folks,

    I found a mac version of the PSU app to help troubleshoot my problem. My problem is that my 2140 is overheating. Here are the links to the app I used to figure it out...
