I didn't know where to post it, but I thought I'd post it here. We tried to tidy up a friend's Mac Mini 2011.

However, it was given to the service before and the service stated that it would no longer be repaired and that the motherboard had to be changed.

When I took the device and opened it the R56D coded SMD inductor on the motherboard is missing.

If the service dismantled it, why did they remove it? Is a separate mystery...

My question is, where can I find this part? Even if I find a spare motherboard, I find it unnecessary to spend just for this part.

Thank you very much to everyone in advance.

Help anyone?

Eventually it got to the point that the frequency of restarts were so great that it became unusable. And finally, it would not even finish booting.

In an effort to solve the issue, I:

1. replaced the fan. (it was getting noisy and obviously failing)

2. Replaced the power supply. (thinking the failing fan had over stressed and damaged it)

3. tested individual RAM sticks by inserted them, one at a time, into different banks.

4. Pulled the fan and shroud to access the drive connectors. Disconnected the SSD. No Joy.

5. Reconnected the SSD, disconnected the HDD.

Aha! It booted immediately!

Thinking I had identified the old 'original' HDD as the villain in my scenario, left it disconnected. Reinstalled the shroud, fan and bottom cover. Re-plugged my connectors, mouse and keyboard - fully expecting to be delivered from my discomfort.

Hit the power button and smiled as I watched the boot status bar scoot up to about 80%. Then... uncommanded restart! About one in six times it would finish the boot process and display the desktop, only to restart within 30 seconds.

So... I'm back to zero and my Mac Mini is a brick.

Confused how this will work w/o OS on the external drive?

Also how will I get the osx back with all of the recovery partition on the new drive?

Will time machine have all of the info needed ?

Followed the answer on the original problem.

received an update to Sierra, now the computer is acting normal w/o any lockups.

The second question is where I needed to think about replacing the original drive.

Time Machine, I understand does not clone the original drive therefore what are the steps to set up a new drive or re-formatted drive to get the recovery partition on the new drive? Does it go back to Lion OS X? why would I need to re-install the original OS X?

Thanks so much for any pointers/help in advance.

I am replacing a few suspect macs on my mac mini logic board with no power at all...

Does anybody know what this small part is (three small smd elements next to fan socket) as on this picture: https://dl.dropboxusercontent.com/u/6935...

This is mac mini 2011 (mac mini 5,1).

Does anybody have any schematics (eg. any "alternative" solder points)?

Thanks,

Adam

I have a Mac Mini 2011 running OS X 10.10.3. I was watching a YouTube video when the machine suddenly froze and "rebooted". However, there was no startup sound (chime), nothing at all from the HDMI output and the fan starting spinning on high.

I've tried resetting the SMC but nothing has changed. Just a solid power light, no chimes/beeps and the fan spinning on high.

Any ideas?
