Mac Mini Intel - no chime, no beep and no picture - fix?

I have Mac Mini Core 2 Duo 1.83GHz, with Intel GMA950 onboard -graphics. Problem is that it powers on but there is no chime, no beeps and most importantly no video. Pressing and holding power button for a while does turn the machine off. Processor and chipset are heating. The light on my USB-mouse blinks when I power on the machine and also if I disconnect and then reconnect the mouse while the computer is powered on. Optical drive does not make any sounds altought I don't know if it's normal for this model, when I had iMac G5 it did make some noise when powering it on. I cannot reset SMC, powering on the machine with power button still pressed for several seconds does not do anything, it should make the fan to run maximum and probably couple beeps. I have able to cause fans to rev. up by pressing the power button and then connecting power cord but this is not the way it's meant to be done.
It is not ram issue, tested with fully working ram and also the ram that was installed in Mini worked on this machine I am now using. I have not tested with another processor, Mini's processor would fit this laptop I am now using so I could later test the processor itself.
What I want to know is that if you have faced similar problems, were you able to fix the motherboard and if so how did you do it? Keep in mind that replacing the logic board is not a way to fix anything since you are _replacing_ the faulty one completedly. I have fixed couple laptops with heat gun but they have always contained Nvidia and ATI -chips which as far as I know tend to heat and break solder much more often than Intel's chips.
So, any ideas?

Sometimes PRAM seems to retain info from a previous startup disk error condition. There is a small chance that resetting the PRAM might help.
You can get a replacement for your original OS X install DVD and any bundled apps from AppleCare (1-800-275-2273) for a shipping and handling fee. You will need to provide your Mac's serial number so they can send the correct DVD(s) for your specific model.

Mac Mini Intel boots to blue screen and gets stuck

Mac Mini running 10.6 Intel won't boot up. I get the chime, then the apple logo, then a blue screen, then nothing but the small rotating circle, which appears and disappears about every 5 seconds (not the color wheel, but the one that just looks like hands on a clock turning.)
Per apple online help, tried starting up in Safe mode. Same result. No boot. Just blue.
Per apple help, I started up in Sinlge User mode and ran Fsck from command line (I don't have the install disk). First run of Fsck said FILE SYSTEM WAS MODFIFED. Ran it again, per apple help. Second time, said volume appeared to be OK. Typed "reboot". Same result. No boot, just blue screen and rotating circle.
Not sure what else to try. Any help?
Thanks

Mac mini (intel) frequently shutting itself down and restarting.

My mac mini has started to immediately power down and restart on its own. I have been using different apps and even just while in the finder deleting old files and reorganizing. I tried a safe boot (holding down shift) and after that I had no audio!? after another restart (regular) it crashed again...I fear that i wont even be able to finish typing this... These crashes are really just the computer shutting down with no notice and resarting on its own... What else can I do here?

Here is what you inquired about my system.
1.25gb 667mhz DDR2 SDRAM (self installed)
I run basic mac apps plus Adobe creative suite 2, quicktime pro, and recently downloaded the 30 day trial of Aperture...
most of the files I have from the older PPC I used to have are on an external HD pictures and my music library.
The Mac mini was new when purchased
devices connected are: linksys 4-port router, D-Link cable modem, Klipsch speakers, a Lexar multi-card reader, Lacie 250GB external firewire drive, 20" Apple cinema display, apple wireless keyboard but a usb mouse (wireless mouse is a battery sucker!), occasionally I attach a panasonic PV-GS300 camcorder - but this has not been attached for weeks and the problem is newer than that.

Firmware Updates on Mac Mini Intel

I have a mac mini intel. Two firmware updates come up via Software Update:
- Mac mini SMC Firmware Update version 1.0
- Mac mini EFI Firmware Update version 1.1
I have tried to install both of these individually several times. Each time, after I double click on the icon in the Utilities folder I enter my password and choose "shut down". Each time, the system starts the process and never really shuts down. Instead, it hangs on my desktop screen. Eventually, I push the power button. Then, I hold the button down like the instructions say. There is a sound and then it reboots a second time and returns to the login.
The problem is that when I log back in, it says the update has not installed!
I'm using the original Mac Mini Intel (the higher cost version) and the OS is totally updated. I need to update the firmware so that my bluetooth headset will work properly.
Any suggestions?

I wonder if Nokia are planning to release a "over-the-air" update for this phone? It's a pain that the update process requires such particular software.
I believe v4 of the firmware is downloadable via OTA. It may be network/firmware dependant though. It does mean you'll have to pop along to the local Nokia shop for this update or follow the instructions above.

Hitachi PJ-TX300 projector and Mac Mini Intel Core 2 Duo?

My PJ-TX300 projector is hooked up via its PC connector to my Mac Mini Intel Core 2 Duo, via a DVI to VGA adapter (which came with the Mini from Apple) plugged into the Mac mini. I cannot get a clear screen picture at any resolution: there is always ghosting. Can you advise me?

Ghosting would typically implicate the video cable. Where did you get it? It sounds like you may have a very cheaply constructed VGA cable and a better one is needed.

Mac mini intel 2 versions 128mb and 256mb graphics in windows ????

Okay I have 2 mac mini intels core solo's and with the same ram 1gb installed and the same windows xp sp1 version etc etc. the one has 256mb video ram and the other has 128mb video ram ????
The 128mb one has a stamp hp42 and a sticker on the motherboard stating locked something ??? tiger = 10.4.5 install dvd
The one with 256mb has hp22 stamp and no sticker but also came with the orriginal tiger for intel 10.4.3 ?? so likely is a older model ????
Does anyone have a clue about this ????

and the same windows xp sp1 version.
I didn't think you could load SP1 onto a intel Mac, how did you get it work? Are you using boot Camp?
No idea about the stickers as I didn't disassemble my mini. Can I ask you you decided to take the computers apart?

Mac mini Intel Core Duo fan very loud and runs at high speed all the time.

I purchased an "Open box" Mac mini Intel Core Duo, 1.66Ghz, 2G ram, 80G HD and SD a few days ago from Fry's.
It runs beautifully except the fan is very loud compared to any Mac my family has ever had. It is so loud that we were thinking of putting it under the desk.
The fan runs constantly, and I mean all the time, at a high speed. You can really feel the air coming out the exhaust vents. The case is always cool to the touch as is the exhaust air.
My aunt bought a similar Mac mini (But only 512Mb ram) the same day. Her's is very quiet. The case feels just slightly warm, not unlike other Mac mini's I've seen.
Should my Mac mini's fan be running this way?
Thanks,
llulua
BTW: The "open box" was sealed with a Fry's label and it said that this had a new warranty. Yet, checking the serial number, it said that it had about 260 days left. I guess Fry's is backing it?
Also, someone told me that perhaps the main wire from the fan to the logic board is disconnected.

Since you have 2 gigs of memory, my thoughts are that when the party (Fry's or the origianl purchaser) upgraded the memory, they neglected to reattach the wire at the front of the Mini under the IR receptor at the right front corner that regulates the fan speed. This wire must be unattached in order to upgrade the memory, and is probably why the original person brought it back, because of the fan noise resulting from failing to reattach the wire. If that wire is left unattached, the fan runs continually at high speed to protect the CPU and system in general. If you do not want to use a putty knife to open the Mini, take it back to Fry's and ask someone who is Mac savvy to open it and reattach the small plastic receptacle at the end of the wire into its socket at the right front of the machine. When I go to Fry's, I am always concerned because the employees allow people to pry keys off of the Apple notebooks, so don't expect that their employees to know or care about anything Mac.

Mac Mini (Intel) and WinXP/Remotedesktop

Hello
I try to run my mac mini (intel) without a screen and without a keyboard using Microsoft Remotedesktop.
Unforunatelly the mac mini will not boot, if it is not connected to a keyboard and a screen.
Running under Tiger the mac mini will boot without connecting a screen and keyboard. Further I can use a VNC-Server and VNC-Client in order to operate by remote control.
Has anyone of you an idea how I can solve my mac mini boot problem?
Kind regards, maninfo

Logitech headset Skype and Mac Mini Intel

Hi,
I own a Powerbook G4 and a new Mac Mini Intel Duo Core.
Both machines run the same latest OSX version 10.4.6.
On the Mac Mini I have a problem using Skype with my Logitech Headset 350 (usb). The system does recognize the headset, but for some reason the microphone of the headset is not working. The speakers work fine. I did set the prefrences right in the Skype menu.
But on my Powerbook G4 the headset works perfectly fine.
Could this be an Intel issue? Maybe I a driver (can't find one on the Logitech site)? Anyone any clue?
Thanks, Fred

did set the prefrences right in the Skype menu.
I have the same headset and it works fine. First, directly connect it to your mini, don't use the keyboard's USB hub since it can only drive 100mA devices. Second, check that the mic is actually on (the blue LED is constantly on, not flashing).
If it still doesn't work go to System Preferences->Sound->Input then select the "USB Headset" and speak into the mic and watch the input level meter. If necessary adjust the "Input Volume".

Mac mini Intel Core Duo and HK Soundsticks USB, Any Problem???

Hello everyone.
I am thinking of "transferring" my "old" HK Soundsticks USB for my sis's new Mac mini Intel Core Duo.
Is there any issue or problem with the mac detecting the USB speakers?? I thought I read somewhere here a while back that generally the Intel Macs might have a problem detecting the USB speakers.
Thanks and cheers.

Hi NewMoses, thanks for replying but you have to be specific, if you just bought your Soundsticks, it is most likely the HK Soundsticks II, is yours?? which has a normal audio jack, unlike the 1st Soundsticks, which has a USB input.
I am sure the Soundsticks II with the audio jack would have not much problem on the new Intel Macs, since they are what I considered a "physical audio input", unlike the USB, which involves the USB technology, where more complication may come into play.
Thanks and cheers

Mac Mini Intel Core Solo 1,5GHz won't turn on

Hi at all!
I'm in a trouble with a Mac Mini Intel Core Solo-based.
Well, when I connect power cord, after a while, Power LED self-turns on (without powering on the Mac), but Startup Chime isn't played, there aren't no video signals on screen, Optical Drive mechanics isn't initialized and no Hard disk Drive noise is audible.
I can hear only (if I put my ear on Mini's body) a bit Fan Noise (and a bit air flow on the back).
If I stay-pressing power button for 4 seconds, Mac turns off. It I re-press that button, Mac turns on again. Finally, if I long-press the power button, Mac DON'T perform PMU reset (with classical speed flashing of power led, Long beep and Startup Chime).
What can I do to fix this problem?
Thanks very much to all readers!

You're right!
I wrote PMU instead of SMU.....in fact, mine is an Intel-based Mac, and PMU is present only in PowerPC Architecture.... ^_^
Sorry for my expression error.....:)
While I'm writing..... I thought that, in my Self-repairing operations on the Mac Mini, I've also replaced the internal 3V battery (because, with a multimeter, I'd can verify that battery voltage was only 1,75V instead of near 3V). After that, I left Mac turned off for a certain interval of time (I was busy in other personal activities). So, when I turned on again the Mac (after the complete reassembly of the entire computer), the Startup chime was played and the Mac beguns to work.
Is possible that, in the Mini - Intel Core Solo 1,5GHz, a low internal battery can cause problems like in the old dear iMacs G3 ????

Mac mini intel shut down problem !! please help !!

hi !
following problem, mac mini intel single core does not shut down, shut down process last 10 min and more (bluescreen, black wheel running) but does not shutdown at all!!
When I log off my user and then press the shutdown button at the login window, it shuts down normally.
Any ideas???
Feeling like being in windows times???
please help
thanks

Good catch. I would never have though of that since I eagerly anticipate each chance I get for a clean install.
I much prefer to get a clean start and consciously change the things I need to work - often I find that the defaults really are better and would otherwise be stuck in habit...

Dual Powermac G5 vs Mac mini Intel Duo

I'm sure this has been discussed already, but I would some more input on this.
I am looking to upgrade to a faster Mac. I am currently running a G4 1.25 DP with 2Gigs of RAM. It's a fine machine, but I would like to take advantage of some of Apple's more powerful units. Anyway, I am considerering a Dual Processor 2.0 G5 Powermac with about 2.5 to 4gigs of RAM, or my other choice is one of the new Mac mini Intel Core Duo models with RAM maxed and a faster larger HD.
My question is--what machine would give me a better performance running Universal Apps, such as Logic, Soundtrack Pro, ect...? Obviously, the Apples are all going to way of the Intel and I have been hearing great things about the new Intels. The Mac-mini has limited expandabiltiy and one Firewire port, but runs Intel. What to do? I may consider the Imac G5 core duo as well.
Any feedback would be appreciated.
Thanks, Randy

well here' my experience...
i recently sold a dual 1.8 G5 with 2GB RAM. reason being simply to get rid of it while it was still worth something. on top of that, it was really large, loud and put out a ton of heat. i bought the Core Duo mini with a GB of RAM as a sort of temporary machine until the next Intel "Pro" towers come out. i've been using it for about a month now for Logic Pro, GarageBand, Ableton Live and Reason and soon my SoudTrack Pro Universal disks will be here as well. i was really concerned that the system would feel slow coming from the G5 but i can totally recommend this machine with confidence as it feel and performs as fast as (and sometimes faster than) by dual G5. i'm talking when using Universal binaries of course. these Intels are fast. the mini is a silent, snappy little machine. there are a few things i miss that will eventually prompt me to buy a tower such as:
limited internal storage options - i believe the largest 7200RPM hard disk you can put in the mini is the 100GB from Seagate. of course, external Firewire and USB storage is always an option.
the limited graphics card could be an issue for some. it doesn't seem to directly affect audio performance but just knowing that it's using your hard RAM is a bit unsettling.
i miss FireWire 800, even though the G5 had serious slow-down issues when writing to fw800.
i miss using two displays.
having said all that; the speed, quietness and cool running temperature of this mini is enough to outweigh any negatives. i notice zero speed decrease from the dual g5 and cost me about a third of the price. it will make a great temporary workstation for me and when the next towers come out it will make a great livingroom entertainment system and perform node duties over gigabit ethernet. don't hesitate. it's a great system.
