I am running Memtest at the moment to see if it picks up anything, and would love to get my hands on the software Apple uses to diagnose hardware issues, but they seem to only be available to Apple Certified technicians under penalty of death. The light on the 'Magsafe' connector end should light up.

I go through the SMC reset procedure as per Article: HT1806. Typically in the morning I see the Mac Pro has shut down and will not startup.

Connect the two-pronged power supply to a wall outlet or power strip. Re: Mac Pro 2006, how do I assess whether the power supply is failing I ask because we have experienced several times over the past couple of years the following issue. Dell P2211H stuck in Power Save Mode - hooked to Macbook Pro. Connect the 'Magsafe' end of the connector to the power supply port on the left side of the Mac laptop. The Mac will save the contents of its memory to disk to save additional power, but it will take longer to resume from standby than it does to wake from sleep. If there is no voltage (+3.3V or 5V, depending on pin), then the power supply may need replacing or a new fuse. Using a multimeter, place one probe on a powered pin (see diagram) and the other on a nearby ground pin.

After that, turn on this PC to check whether it can boot normally. Unplug all four connectors so the power supply is isolated, but plug in the 120v power cable. I have escalated the issue and they are awaiting me to send it back one more time. 8 hours ago &0183 &32 Shut down your Mac. It has been sent in 3 times to the Apple store and they haven't found anything wrong (minus a false positive bad stick of Ram last time, which is why I'm running MemTest now). It is quite possible that same stick is the stick that's holding the test up, but a second MP 6,1 I was also testing Diagnostics on hung at the same 1 minute remainig.this was left going over the weekend, so it had plenty of time to get through the test. I have tried running Apple Diagnostics, but the system sits at 1 or 2 minutes remaining.this is with either all 64GB of Ram installed or just 1 stick in there. I have to unplug everything and let it sit for awhile, sometimes it will power on after a few minutes with nothing attached, sometimes, it takes hours, but it always eventually powers on.and once powered up, it consistently works until I shut it down again.ДЄs a professional broadcast facility, you can see the need to have the system work every time, not maybe today, maybe tomorrow. Everything is plugged in (2 HP Dream Color monitors, 1 Wacom Tablet, 1 Sonnet 10GB TB adapter, 2 USB3 external drives.one SSD, one rotational, both have their own power supplies) I have one Mac Pro 6,1 Trash Can that is completely dead in the morning after being shut down and sitting all night.
