Early 2006 Mini Fan/LED Problems

Just posting here in case anyone is having the same problem.
I was having problems with my early 2006 Mini (Core Solo). In order to boot the machine, I would have to reset the PMU, but then the fan would run at full speed the entire time the computer was powered on, including boot time and shutdown. In addition, the status LED would not work. I tried resetting the SMU, but I would subsuquently have to reset the PMU again to get the machine to boot and the problem would still be there.
The solution turned out to be very simple. I was using the wrong power supply. I had a 85 watt supply from the G4 minis. The supply designed for the intel minis is the 110 watt one. Once I plugged in the 110 watt supply, the machine powered right up without complaint.

Edit:
Run the Apple Hardware Test to see if the fan is working properly.

Mac Mini Early 2006 Mini PCIe SATA Card Not Showing Up

I'm trying to add a couple of SATA ports to an early 2006 mac mini by swapping out the mini PCIe AirPort for a SATA card. This is the card I'm using http://www.startech.com/Cards-Adapters/HDD-Controllers/SATA-Cards/2-Port-Mini-PC I-Express-Internal-SATA-II-Controller-Card~MPEXSATA22I, problem is it doesn't seem to show up when installed in the mac. The card works perfectly when installed in a different machine.
The AirPort card shows up fine when swapped back, so the connector's okay. But with the SATA card installed, System Profiler says the computer doesn't contain any PCI cards. I've tried resetting the NVRAM with no success. I don't even see an entry for the device it in the ioreg output, so I'm thinking there might be a power issue. Does the mac mini supply both 3.3V and 5V to the mini PCIe connector? Is there anything special I need to do to get this card to show up?
Thanks.

There a long thread about this on the 123MacMini forum. At page three, they mention drivers (you need drivers, right?) and there is a link...

Actually, that thread might refer to a different, but similar, card.
Don't know if it finally worked. Be very interested to hear. (Not sure why Apple is/has always shunned eSATA?)

Using early 2006 Mini as DVR/streaming box to TV

I've got a Mini with the 1.66 Core Duo processor, 2 GB RAM and 160 GB on board HDD. I want to know, can I connect it to a TV to use as both, A) a streaming device for Hulu/Netflix/Amazon VOD? and if so, how? B) Can I also use it as a DVR via EyeTV Hybrid and the EyeTV software? I'm assuming I'd need a DVI to component(for my older TV) or HDMI(if I get a newer TV) cable and maybe some sort of audio out since I doubt the DVI in the 2006 model supports audio out? Any help is very greatly appreciated.

The only reason I have a Mac Mini was due to good friend & her desire to have the new MacBook Pro 13.3. She actually wound up giving it to me. It is a Core Duo 1.83. Needless to say I was stoked! I have been using my PowerBook G4 15" & love it. However the Mac Mini blows it out of the water everything wise except for portability. I was saving to purchase a used 15.4" Aluminum MacBook Pro, but now that I have the Mac Mini, I am completely content to use my PowerBook G4 when out & about.
The Mac Mini is an amazing Home Theater Hub! I use mine with a Samsung LN-40B750, Bose Cinemate , PS3 60gb & Logitech Media Pro Keyboard for the PS3 (never actually used it with the PS3). I have my Mac Mini set up with DVI-VGA & 3.5mm to RCA Stereo Cable. Just remember 1280x720, this resolution works perfectly.
My PowerBook G4 works exactly the same as the Mac Mini, just a lot slower...

HT3382 I have an early 2006 Mac Mini and need to connect it to a VGA display. What connector should I use?

I have an early 2006 intel core solo Mac Mini (locted in India) and need to connect it to a VGA display. I have looked at the support articles but can't figure out what adapter to use.

There was a DVI to VGA adapter included with the early 2006 mini. The one that I have looks like this
You should be able to buy one, although it's not currently listed in the US Apple online store.

Mac Mini (Early 2006) and WPA2

Welcome to the Apple discussions.
The early 2006 mini supports WPA2.

HT1338 mini late 2012 fan system problem

Welcome,
I have problem with my mac mini late 2012 with fan system i think becouse my fan's rate still show me 1800rpm (while temp. is 49oC and when is over 80oC)
I tried reset SMC but it still doesn't work.

One thing that Apple does well is build very quiet machine's and by default the fan will eventually ramp up without third party fan control utilities. The problem is that, the default settings are way out there at around 90c and then at that point the fan gets kicked up to full speed until things cool off. Like you, many of us here also think that is a really bad way to treat hardware and use some type of third party Fan Control utilities.
For example: I have one of the first Intel iMac's, an Early 2006 Core Duo and have used smcFanControl on it from the day it was new. For over 7 years I have ran it's fans from 100 rpm over default in the winter to 500 or 600 rpm over the default in the summer and it has never had a single overheating or hardware issue. It is maxed out at 2GB of RAM and can only run Snow Leopard, but I have kept it, because it is still a very good machine for the grandkids to learn and play games on.
On my Mac Mini running Mountain Lion I also use Fan Control 1.2 and really like it over smcFanControl because I don't have to worry about having different speed sets for different activities or seasons.
Here are my Mac Mini's Fan Control settings.
(sorry I'm old and still use F to know how cold and hot things are)
If you would like to increase the set point that the fan starts ramping up, increase the Lower Threshold slider.
If you would like to have the fan speed ramp up at a slower/flater rate, increase the Upper Threshold slider.

No sound no audio in Mac Mini Early 2006

I'm using a Early 2006 version of Mac Mini, I have upgraded the CPU to Core 2 Due 2.0Ghz, and ram to 2G. So it runs Mac OS X 10.7.5. Recently, I have no sound but used to have in the past. I've checked systems and I have no sound output. Output volume is grayed out and shows muted. Also on System Report, the "Audio" page is totally blank which used to show Intel HDA specs. I've tried resetting PRAM and SMC (twice)- that didn't work. I've tried plugging in speakers, headphones, etc. Doesn't work. Is this a hardware problem? Any ideas? I have not tried to re-boot from original optical disc and press C, but I will try to look for the old disc first.

I suspect you disconnected something during the disassembly/reassembly. Take it apart and check your work

Digital Audio Broken on a Mac Mini (early 2006)?

I've got an early 2006 Mac Mini 1.83GHz which I'm trying to use as an HTPC. When plugging in an TOSlink to miniplug cable to the audio port I get the "flipover" to Digital Out in sound preferences but no sound from my Pioneer AV receiver. I've made all the correct adjustments in the receiver preferences and tested them with a iMac and sound plays through just fine.
Headphone and Internal speaker work fine on the Mini and the cable is fine as noted above with the iMac test. Is it possible that the optical digital audio portion of this jack is bad?
Apple Support doesn't seem to think it is hardware related. I've re-installed OSX and checked permissions. I don't have the restore disk to be able to do a Apple Hardware Test and the Leopard disk does not contain it.
Any ideas as I've run out aside from taking in to an Apple Store for evaluation?

Took to Apple Store and they fixed the unit with a new digital audio card. $49. I'm happy.

2006 mini getting hot??

I have late 2006 mini baught in march 2007. Seems getting a little hot. Fan is a little louder all of a sudden. Or maybe I'm imagining it. But does feel a little hot. Maybe I need to move it from under my monitor stand so it can breathe but it has been there since 2007 without any problems. It is core duo not 2 duo. 2gb of ram I added at the store when I got it. They installed it.
Anyhow I installed temperature monitor widget and it says "CPU A Temperature Diod 62 degrees celsius" and "CPU A Heat Sink 53 degrees celsius". Also I installed "fan control 1.2" as written on another even though for macbook pro works on mini well. But it says left fan 3850 rpm and right fan -1 rpm. Is that because mac mini has only 1 fan.
Anyhow is 60 degrees about normal?? Or even idle (or even just replying here and only 1 tab open) 50 - 60 is too much?? Any opinions appreciated.

Edit:
Run the Apple Hardware Test to see if the fan is working properly.

MacBook Pro (early 2006) to Sony Bravia

Hi there
I have a MacBook Pro (ealry 2006) and would like to connect it to my sony Bravia.
I also Have a MacBook Air which I could use for the same purpose but I would prefer to use the above.
I have heard that if I buy the cable (iWires DVI to HDMI Cable) at Apple (£29), this will only transfer the video and not the audio.
What is the best way to achieve my goal without a lot of cables lying around?
Thanks

The Early 2006 model 1,1 Core Duo has a Mini-DVI port, not a Mini DisplayPort or DVI port.
Depends on what input plug you'll be using on your TV. VGA, DVI, Composite or HDMI. (Composite is the red, white and yellow RCA plugs on your TV or red, white and S-Video plugs.) You'll need a Mini-DVI adapter and a cable from that to your TV. Here's the various types of Mini-DVI adapters on AmazonUK.com http://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=m ini-dvi+adapter&x=9&y=11
You'll also need audio cables to the TV using a 3.5mm stereo headphone jack to RCA sound plugs for VGA, DVI or Composite. You attach it from the headphone jack of your MacBook to the appropriate input plugs on your TV http://www.amazon.co.uk/s/ref=nb_sb_ss_c_2_17?url=search-alias%3Dcomputers&field -keywords=3.5mm+audio+cable&sprefix=3.5mm+audio+cable%2Caps%2C565#/ref=nb_sb_nos s?url=search-alias%3Dcomputers&field-keywords=3.5mm+to+rca+audio+cable&rh=n%3A34 0831031%2Ck%3A3.5mm+to+rca+audio+cable
If you connect the MacBook using a Mini-DVI to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo system for audio if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. The Mini-DVI to HDMI doesn't carry audio and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.

Help! My ViewSonic monitor doesn't want to work w/ my Early 2009 Mini!

Have an 2 GHz Intel Core 2 Duo, 4gb RAM, Early 2009 Mini (macmini3,1), 10.6.8 Snow Leapord with a ViewSonic VA1703wb monitor.
My problem started a few weeks ago. All of a sudden I discovered that if I turned my ViewSonic VA1703wb monitor on before the Mini, the power button was green, but the screen was black. Turning the Mini on then the monitor seemed to get it to work. Now for the last few days, the monitor either would show the Apple logo and then go black or just have the power light blink green and sometimes yellow with the screen slightly flashing, but was black (with the Apple logo screen not even coming up). I have the two different adapters to use to plug in VGA. I've been using the Mini-DVI port adapter since I got the Mini a few years ago (on eBay which came w/ the orignial box, discs, manuals etc.) w/ no problems.
Tried the Mini Display port adapter that I had in storage and it did the same thing! Then I remembered that there was another adapter in the Mini's box. Happen to have a Apple Studio Diplay and would you believe the adapter (Mini-DVI to DVI) in the box fit on the end of the Display's cable!! I couldn't believe my luck! And, the Mini works with it! At least I got it to work! The "About This Mac" says the following for the display: NVIDIA GeForce 9400, 256MB RAM, Display Connector Status: No display connected. (How can it say that "no display is connected, when the Studio Display is??? I'm typing this using the Studio Display!) I also have an MDD and hooked the ViewSonic up to it and it works!
When I did get the ViewSonic to work with the Mini, I noticed that my desktop photo wasn't showing, just the Snow Leopard purple space one. I put my photo back on the ViewSonic. When I got the Apple Studio Display working, it at first didn't have my photo showing, just the purple one. And it didn't have any icons etc. Had to power shut off the Mini and then start it up again and then everything was showing up fine.
The other day I read that the adapter has a firmware update from Apple and that maybe the problem. Can't understand why an adapter has firmware. Also I've read that the PRAM (called something else w/ Intel) may need reseting or that the HD could be going downhill! I was also wondering if the video card was messing up. I hope and pray the problem is only software, as I'm not going to take the case apart and have something break in the process. I've replaced hard drives, RAM, PRAM batteries and a card in PowerMacs with not much difficulty. If my Mini was the newer design where you can take the bottom off, then that would be fine... Since the Mini works with the Studio Display, I wouldn't think it was the video card, but with computers anything is possible. I will be sick if it's the hard drive! 99% of my documents and photos are stored on a USB drive (as to not fill up the 120GB HD).
Sure hope someone can assist me with this nerve-wracking problem. Thank goodness I have the MDD as a back-up, but its RAM is maxed out to 2GB and it seems slow on the Internet and when I edit photos.
Thanks very much.

Well, VGA & DVI use different ins on the adapter, so it is likely some HW issue.
The purple space issue sounds like the Mini thought it was a second extended display.

Early 2006 iMac processor upgrade

I have an "Early 2006" Core Duo 20" iMac. I know that the processor can be upgraded (this model was socketed, unlike later iMac models).
My research on the internet concerning this comes up with info that outdated. I know that it is difficult, and I know that the chip needs to be a "mobile Core 2 Duo chip" (those that
My questions are:
1. Has anyone on this board done this?
2. What processors am I limited to, as the info I see is a couple of years old and applies to older processors? I obviously do not want to insert an incompatible chip or one that runs too hot for my logic board & fans (even though I am sure I could use SMC fan Control to help out).
3. Is the old limitation of 2gb ram limited by the 32-bit nature of the Core Duo or by the logic board... meaning if I DO upgrade to a 64-bit Core 2 Duo chip, does that change the 2GB RAM limit?
BTW, these are two of the older articles I've combed through:

Hi Charles
It's a little off the subject, but it would probably cost you less in the long run to sell your Core Duo and buy a New, an Apple Refurbished or Pre-Owned Core 2 Duo.

Mac Mini fan won't turn off (only while powered on)

Unlike some stories i've read while crawling around the internet trying to solve MY problem, it's not that my fan won't shut off EVER. The fan shuts down when i put it in sleep mode or shut down the Mini. No problems there. But while the computer is in operation, the fan runs non-stop.
It wasn't always like this. In the 2.5 years i've had my Intel Mac Mini, it has more and more frequently employed the fan. As of the last couple months, the fan is now in continuous use, as long as the computer is in operation. In addition, all the programs take much longer to load, and i'm dealing with programs crashing (Firefox & Safari far more than anything), Bluetooth not functioning, and the front light on my Mini is out.
As for the fan, the Mini is getting plenty of breathing room...even more than it had before the problem. I also have 22GB left on my Mini's hard disk.
Are all these problems related? Am i really just working on my last thruster here? Is my dilitium crystal just about dead? Is a warp core breach imminent? I do not have AppleCare, and i don't know if the Apple Store would look at it for free if i brought it in. Any help (no matter how small) would be greatly appreciated.
MY STUFF:
Mac Mini - 1.66 Intel Core Duo, 2G 667 HHz DDR2 SDRAM
Iomega MiniMax 1TB external HD (for audio/video files)
Iomega Minimax 1TB external HD (for Time Machine)
OSX 10.5.6

When you start your mini from cold (after at least an hour powered down) does the fan spin up to full speed immediately, or does it start out normally and then speed up after a few minutes or so? Did you have the system open for any reason just before this behavior started?
If you had the system open, it might be something as simple as the fan control cable that is not connected. When disconnected, the fan will run at full speed all the time.
It the fan runs at full speed almost immediately from cold, then it would suggest one of two things: either the system is suffering from something like a loose heatsink, or there is an errant process running that is putting the system under heavy load. You can check that by opening Activity Monitor (in Applications>Utilities) at looking to see if the CPU load is consistently high. If it is, look for a process that is causing it.
If the fan runs quietly at first, and then speeds up, after a few minutes, then it does seem likely to be a heating issue. Aside from making sure the vents around the base and on the back are clear by using a good vacuum cleaner, it's possible there is enough debris inside to obstruct the airflow. If you've opened up the system previously for any reason, now might be a good time to do so again, for a quick inspection and clean out.
I would also perform an SMC reset if you have not already done so:
To reset the SMC on an Intel mini:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.
And to ensure you are not suffering from a range of broad 'tuning' type issues, download a copy of YASU (http://jimmitchelldesign.com/projects/yasu/) and run all tasks. This clears cache files, resets logs files, updates prebinding, performs a permission repair and a few other tasks. After the reboot (which will be slower than usual) your system should run a little better.
... i don't know if the Apple Store would look at it for free if i brought it in....
You can make an appointment at the 'genius Bar' of your local Apple store - they will look at your system for free, and help with a diagnosis. What they generally wont do without charging for it is anything that involves opening the system up. However, it's worth paying them a visit for a bit of hands on work!
