Dead mini? Fan blows hard when plugged in-- that's it

Has anyone experienced this before?
My Mac Mini core duo has decided to do one thing these days-- as soon as you plug in the power brick cable into the mac, the fan blows like mad. Nothing else happens.
I've tried swapping out the RAM, but that ain't fixed it. I'd have problems trying a spare processor though.
Any tips? Is it economical to take it to the apple store, or is it eBay time for a secondhand one?

Many thanks for the tip.
Unfortunately, this little Mac's DVD drive is busted too!
I've just tried swapping the processor for another core duo (an identical part!) and that failed. I suspect it's the logic board.
Certainly, I have had the mac opened up, but it failed almost 3 months after it last opened -- and I am fairly proficient.
I feel this mac is now a paperweight. : (

Fans blow hard upon starting up

Dual processor 1.8 mhz. Fans blow hard upon starting up. It was freezing upon start up as well. Then I replaced the 1/2 C battery. The fans still blow hard but it doesn't freeze up on start up. Do I need to replace the other battery by the hard drive?

So I did run DU and encountered problems. "Disk Utility stopped repairing since following error encountered: The underlying task reported failure on exit."
Hmmm....

Over the years, I have encountered that response from Disk Utility and DW has come through. Worth a try, anyway.

My new iPad mini will not charge when plugged into adapter. Any suggestions?

my new ipad mini will not charge when plugged into adapter. What should I try?

Does the charger get warm at all? Plug the cable into your computer with iTunes open. Does it say not charging.? If it does, the cable is good. The iPad will charge very slowly when pluged into your computer.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

When I plug in iPhone (5.1.1) to computer, playlists show up on the iPhone (when plugged in), that do not appear when it is not plugged in. And I can't erase them. I have iTunes match, and deleted all my music on the iPhone, but that had no effect.

Help greatly appreciated.

Unplug your Iphone out of your computer and replug it back in. It took me several times before I could do this

Fan blowing hard upon set to sleep

I have a few problems at the moment with my Imac G5. It starts up extremely slow..like 10 minutes and then it makes the fan blow when I put it to sleep and the light/heart does not light up anymore. The only thing I can do is to keep the powerbutton in and kill it. Does anyone know this issue?

Welcome to Discussions - you can try starting from your install disc and then use
Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
See what comes up and please post back with results.

Dead Battery will not reboot when plugged in

Anyone else had this problem?
Phone dies when battery reaches about 5% (not 1%). Plug in the charger but it takes 10 minutes before you can switch phone back on again?
Maybe this is covered elsewhere but with all the dodgey battery posts about it is hard to find things.
Thanks.
WP is dead
Solved!
Go to Solution.

If it was only ten minutes I'd be happy, but I plugged mine in and it didn't boot at all, in fact 12 hours of charge later it was still sitting on the battery icon with red bar and had not charged a bit!
It appears that when it's run out completely, (which depends entirely on what the phone thinks is completely I turned mine off at 7% remaining and left it off until I got home to charge it) the Lumia doesn't want to charge or power up.
It's almost like it's stuck in a cycle of low charge, the image of the battery low icon uses charge and the phone won't start until it gets charge so it just sits there in a perpetual state of not charging. Run it dead and it will fail to charge or start until you randomly fiddle with the buttons, connect and reconnect the charger, in fact it took connecting it to my laptop this time to start it.
The Lumia it seems has high battery usage probably due to 3G driver issues as it overheats in your pocket if not in range of a strong signal probably as it just remains on and searching. It hates being run out, which seeing as it chooses what percentage to run out at is almost impossible to avoid and it charges irregularly sometimes the charge lasts 18 hours sometimes it lasts 6. As someone who has had Nokia's since the very first mobile phones came out this phone deeply dissapoints and has brought me to the stage of finally saying brand loyalty is no longer enough I am considering looking at alternatives once my contract on this current underperformer expires.
I told myself after a few Nokia problems with other models (which I lived with because I love Nokias) that this was Nokia's last chance for me and at first I actually thought they had pulled the stops out and achieved something. A short period of ownership has sadly proven this not to be true.
If a random charging battery with no longevity is the best we can hope for Nokia is about to lose market share, sad really

Fan buzzing only when plugged in?

Hello all,
I've noticed a low buzzing coming from the rear fan sometimes when the iBook get's really hot. Thing is, it never happens when on the battery, just when it's plugged in. It's not too loud at all, but it is noticable compared to the otherwise silent like hiss of the fans normally. It almost sounds like the tiny blades are softly brushing against something. When the laptop cools down a bit, the noise goes away, and I just hear the silent like fan again.
Again, this never happens when the iBook is running off the battery alone. My energy saver settings for power adapter and battery are both set to Automatic CPU.
I took it to the local Apple store to have it checked out. They tested the fans, while plugged in, and there was no problem. I even sat there for an hour and a half running intensive games - games that produce the sound at home - and nothing. I think it's just too cold in the Apple store
Any ideas? Why would this only be happening when the laptop is plugged in?

There's definately no "unusual" sound coming from my hard drive. When I turn the iBook around and put my ear to the back vent, it's pretty apparent that that's where the noise is coming from.
Also, when I brought the iBook in to the Apple store to have it checked out, the service tech ran a utility that cranked the rear fan to the max. The fan, when activated manually, sounded fine. It just made a normal "fan noise". Of course the iBook is cool during this process, and refused to get hot enough in the store (it's an ice box in there).
When the iBook gets really hot, and the fan kicks on, there's a distint "buzzing" that happens from the rear fan. It must be temperature related. The heat must expand a part near the fan or something, because it sounds as if the blades of the fan are rubbing against something.
Apple can't reproduce it in the store, so they won't do any work on it. I just hope it's nothing that will harm the computer over time.

My Mac Pro won't start up, fans blowing hard.

Hi,
I bought a secondhand Mac Pro 1,1 - dual core 2,66 Ghz a few months ago.
The company I bought it from put an ATI Radeon 5770 HD and a 150 GB SSD in it.
It ran completely fine untill yesterday afternoon.
I needed some extra storage space for my files, so I opened up my broken iMac G4, unattached the hard drive.
This is what happened:
I shut down my Mac Pro,
with all the cables attached I moved the Mac over,
I opened it up, put in the extra hard drive in bay 3 (power chord still attached), closed it and tried to power it on.
The graphics card's fan began to blow immediately.
I heard no startup chime. Ten seconds later the main fan began to blow.
There was no video output, the screen stayed on stand-by.
The Diagnostic leds show only 'trickled', no other leds.
I searched alot on the internet for a solution, and tried all the resets and solutions I could find.
A brief list of what I've tried:
-pram reset
-smc reset (manually and automatically)
-boot without graphics card
-boot without RAM
-boot without cd-drives
-boot without harddisks
-I pulled all elements out (graphics card, ram, power supply, HD's, cd-drives) to check for broken or loose connectors.
Nothing worked so far.
What I did find, are some damaged power cords from my cd-drives:
http://www.flickr.com/photos/75710783@N02/8389915636/sizes/o/in/photostream/
Could this be the thing that started this problem?
And if not, what could possibly be wrong?

The existing breaks in the power leads for the Optical drives should not cause this problem when the optical drives are disconnected, provided they are not shorted to something else.
But if, at some time, they shorted out, it could have confused or damaged the power supply.
First, reset everything:
Remove AC power.
Press and hold the power-on button for a quarter minute (this drains the capacitors).
Wait a quarter minute more.
Restore the AC power cord.
Wait a quarter minute more.
Attempt to start up again.
To check for damage, measure the DC Voltages at a Molex connector (such as the one that is not damaged). You should find a bit above 5 Volts on one of the outside leads (often red wire) and a bit above 12 Volts on the other outer lead (often yellow wire). This should be relative to either/both inner wires (often black wire) or any other black wire, or the frame.
( If you do not already have one, a perfectly serviceable digital multi-meter for this purpose can now be had for as little as US$10, and does not require a degree in rocket science to measure DC Voltages. More money buys a higher-quality instrument with additional precision that is simply not necessary, but not an impediment)

Mini fan runs even when turned off

Yesterday the fan started running loudly (seemingly top speed) and it won't stop even when the computer is turned off (only way to kill it is to pull the power cord). The vents on the bottom have a bit of fuzz on them, but nothing outrageous. Other than working on the motherboard (which I'm not capable of doing), what can I try? I did reset PRAM...nothing changed.
Thanks!

Is the power/sleep light on or off when the Mini is "off" but the fan is running?
If the light is "on" in some fashion, can you start the Mini by pressing the Menu button of your Apple Remote once?
If you can't do this, I fear you have a logic board problem similar to the one first diagnosed by brisbanebazza:
http://discussions.apple.com/message.jspa?messageID=9524465#9524465
Unless you know someone who can do electronics soldering, generally the fix for this would be to replace the logic board, which is usually too expensive to be economical in my opinion.
BTW, no harm in gently vacuuming the fuzz out of the vents, with the Mini closed up, not open.
After you vacuum, you might also try something wacky: try running the mini upside down for a short period of time.

Neo Platinum mobo dead, NB still heats up when plugged in

I received a replacement neo platinum two days ago, and setup my computer. It was working fine and I went through several reset and power up/down cycles and it worked great. Yesterday I powered up my computer, did some work and then put the computer on hibernation and left the apartment. I came back in around 4 hours and the computer refused to power up.
I opened up the case and made sure everything was plugged in, but nothing happens when the power button is pressed. I checked for shorts by taking the mobo out of the case, I unplugged unnecessary components, tried resetting the CMOS to no avail. I also tried a different power supply.
I did notice that the ethernet LED lights up green as soon as the power supply is turned on, the main power led sometimes blinks once when the power supply is turned on, and the northbridge heats up when the power supply is turned on. If I just leave the computer sitting around like that, it gets so hot that I can't hold the heatsink.
Does anyone know why the NB might be heating up eventhough nothing else seems to work? Could the NB fry itself like that?
I already went through 2 RMA cycles, and had this problem before. I am extremely annoyed and confused... If I can't figure out what is going on I might have to go out and buy a different motherboard.
thanks

I tried another power supply, that didn't fix it.
I don't have any other memory to try it with;the only thing I know is that it was working fine in the morning.
I do not have another CPU to try it with either
I am using a Chaintech AV710 soundcard
the heatsink is an arctic cooling temperature controlled fan and heatsink combo
the NB just had the stock heatsink on
I had 4 other temperature controlled fans in the case, all connected directly to the power supply with 3 to 4 pin adapters, so the mobo only had the cpu fan attached to it
ethernet cable was plugged in
a serial x10 remote receiver was connected
a Cornea LCD monitor was connected
There was a NEC dvd burner and a lite-on dvd drive was connected
two harddisks were connected (both parallel ide,one on each channel)
the last time this happened, the computer was working for over a month, and then one night it reset itself, and then shutitself down and never came back on. This time I put in hibernate myself.
Cool'n'quiet was on, everything else in the BIOS was pretty much in the default settings
is there any other information that would be helpful?

Mini says tunes there when plugged into comp, but unplugged, no songs

Maybe someone else has had the sort of nightmare experience I have had with my ipod. For 10 mos, it would not allow me to put songs on. I finally called tech support(helped 1x, now insist I must pay $59 to get their crappy technology to work properly). After 2 1/2 hrs on phone, installed recent software on comp and iPod, got 127 songs on it (CDs prev burned on HD). I want to add more songs (it says it will hold 1000 songs....). I followed the instructions I'd been given to put them on the ipod - incl put in disk mode, manually update. It looked like it was downloading tunes. iTunes says the songs are on the iPod. However, when I disconnect from computer, there are only the orig 127 songs I got installed on it 1 wk ago, i.e. not one of the new 255 songs was installed. Can anyone help? email is [email protected] I am really, really regretting having spent $350 on this piece of junk, but maybe the problem is me (I certainly doubt it). Feeling v disenchanted w apple and their crap service right now.

If you have your ipod set to manual update then you have to manually drag all of your songs from your library to your ipod "icon" on the source list. I believe that is where your "disconnect" problem lies. You have to remember that all the songs you burn onto ITUNES are on your computer's hard drive only until (in your case) you manually transfer them to your IPOD's list of songs. You can certainly fix this manual issue by changing your IPOD settings to auto update. Of course that will create other challenges say if your computer's library is larger than your IPOD capacity etc and so forth. Hope that helps

My ipad Classic has suddenly gone dead - no indication of charging when plugged in - nothing! Is there any way to reboot it?

After about five years of reliable use, my ipod Classic has suddenly gone dead. Charging seems to have no effect - no sign of life. Is there any way of rebooting it?

Start here... http://www.apple.com/support/ipod/five_rs/classic/
If you try the above and all else fails, leave the iPod unplugged for a few days. This should drain the battery. Once that's done, plug the iPod into power and wait (for up to thirty minutes) for the screen to turn on and charging to begin.

Mini will not respond when plugged

Mini driving me nuts. I updated it, I updated iTunes, I tried to reset it using HOLD ON and OFF and also MENU and SELECT. Still no response, no hourglass, no apple signal ...nothing. Anything else I am missing here? Windows 2000 PC. I appreciate it. Thanks.

Alina,
There's a couple of troubleshooting articles here to look at.

PowerMac G5 freezes, fan is blowing hard

Hello everyone:
My PowerMac G5 is about 3 years old, running OS Tiger 10.4.11 and has been working fine. A couple of weeks ago, it started freezing up overnight with the fan going into overdrive and blowing hard. I can only shut it off by pulling the plug. At restart it makes 2 clicking noises, and then it boots fine--and works fine until the next freeze.
It started happening more often which prompted me to run the disk utility. It came up with a message that "Volume header needs minor repair." I repaired it using the OSX CD.
Question: does anyone else have the same problem and did the utility fix the problem for good? Or should I be thinking about a new hard drive? Thanks in advance for your help!!!

I can say I have the same problem with different results. I too have been noticing this is primarily happening when I out the machine to sleep. I will wake up in the morning to find the fans going full blast. I have also encountered getting a phone call from someone at home telling me my computer sounds like it's about to blow up! I put it to sleep each morning after checking my emails and heading out to work. At times the room can get get a bit warm and this may be adding to the issue. I have also read not to use any animated screen savers (which I have been) and so I may just do away with those to see what happens.
I have recently encountered more system freezes where I will have audio playing, the machine locks up with the audio sounding like a broken record repeating itself. The only way to get out of it is a hard reboot by holding the power button in. Same way I have to reboot it after I find it in the morning with the fans at full speed. I have also encountered a few kernel panics as well while in the middle of working in Photoshop or web browsing using Safari or just checking emails.
I have run the Apple Hardware Test CD both Quick and Extended Tests and get a pretty balanced result of everything is OK, or a Logic Board failure where it gives me this error code - 2STH/1/2:CPU B AD7417 AD1 - from which all I have been able to gather is something to do with a thermal sensor for one for the CPUs?
My CPU die temps are not horribly hot although I notice CPU B usually runs about 7-10º F warmer than CPU A. This is pretty constant as well no matter what task.
I have reseated all the boards, used compressed air to clean it out, cleaned the fans and radiator the best I can. I had one of the CPUs replaced less than 3 months after having bought the machine from Apple. I sure hope one of the CPUs is not going bad again as my AppleCare just expired 2 months ago.
I'd really love to know specifically what the error code I get from the AHT means. So far, I have been blessed not to see any leaks inside the case which seems to becoming a more frequent issue with my model machine.
I too am very interested to hear from others who are experiencing this issue. My S.M.A.R.T. status is good so I know my HD is fine. I have swapped out graphics cards and memory to the originals, neither of which have changed anything. Going to try reseting the SMU on the board again along. Also replacing the SRAM battery even though I know it has nothing to do with this specific issue. I just notice after forcing the machine to shut down and reboot, the date likes to come up as 1969 a lot of times.
