Intel Mac mini: Power LED Brightness

Hi,
I've discovered a quirky little 'feature' with my new Intel Mac mini. The brightness of the power LED varies with the time of day - late at night the LED is dimmer that first thing in the morning.
I've verified this by changing the clock time manually and sure enough as soon as I click save the brightness changes.
This didn't happen with my previous PowerPC mini. Anyone else noticed this with the new Intel minis?
Thanks,
Nina

Thanks
I noticed it when the PowerPC and Intel minis were side by side one evening and my initial thought was that maybe it's just a duff LED. This morning it was back to full brightness and now tonight, it's dim again. So yeah, I just guessed that is was related to the time.
Nice article btw, highly amusing

  • G4 power brick with Intel mac mini?  is this possible just to test?

    A friend gave me an Intel mac mini, 1.60GHz CPU model, but no power supply.
    I tried using my G4 mac mini's 85W A1105 power supply on the intel mac mini but nothing happens. I have to unplug the power supply from the wall to get it to power on my G4 mac mini (it apparently doesn't like being plugged into the intel mac mini).
    Is it possible to use the G4 2005 power supply with the Intel mac mini if only to just test to see if the intel computer works? I don't want to buy a MA407LL/A 110W intel mac mini power supply only to find that the computer he gave me is broken.
    Just wondering if anyone had any tips/ideas how to tell if the Intel mac mini works at all or if I'm just going to have to find someone who has the 110W intel model supply to test it...

    The G4 mini power supply is rated at a significantly lower current capacity than the Intel mini requires, thus while some have had marginal success in using an old supply with a newer system, almost any tolerance variation will mean the Intel box won't run with the G4 supply. Not only that, but since the Intel system will load the G4 supply at a level it was not designed to accommodate, you could damage your G4 supply by trying.
    If you have an Apple store in your area, I would take the Intel mini to the genius bar there where it can be tested, thus avoiding you having to buy a new supply without knowing if it will work.

  • Can I use a Power PC non intel Mac Mini as an external HD with my iMac 3.06

    Can I use a Power PC non intel Mac Mini as an external HD with my iMac 3.06 Intel Core Duo
    I can't figure out how to get this to work. Is it possible?

    Will it work if I connect via usb instead of firewire?
    No. There is no "USB Target Disk Mode".
    Just so we're clear, when you start your Mac mini in FireWire Target Disk Mode (TDM - holding T on startup), do you see a FireWire icon on the Mac mini's display? IIRC, it's not required that the Mac mini be connected to a display for TDM, but it would help diagnose whether or not the mini is actually starting in this mode.

  • Need help with Intel Mac mini... potential logic board failure...

    Hey everyone! For the past couple years, I've been using an Intel Mac mini which I was able to afford before rough times hit for me. It has been a champ for a long time, until recently. In the past week, the clock would lose time ever so often, and last week, whenever I'd try to power it up in the morning (as I shut it down every night), it wouldn't start up most times (meaning, you hit the power, nothing... no LED, no fan, nothing on screen, nada). After a while, I would somehow manage to get it to start. I assumed at this point, the lithium battery (coin type CR2032, not the traditional 1/2 AA purple battery) was shot. Since I'm in the middle of a job transition, I was waiting until I had time to put in a new battery, which I was planning to do this weekend. Then Wednesday happened...
    I go to start it, nothing... A week before this, I started losing time and sometimes it would not boot. I figured eventually I would be able to start it since I was able to sometimes get it to start after a half hour or more. That didn't happen. So I decided to go ahead and swap in the new battery. I do that, power it up, nothing. I reset the SMC (same as PMU on the PPC Macs), to no avail. I reseated the RAM, and did everything I could think of, but it's deader than Elvis. I also had took the power supply to a guy who had a voltimeter. He said voltage was getting to all pins.
    I went back and read some of the archives on this board. Someone mentioned something about a repair exception. It mentioned that sometimes if you call AppleCare (even if you don't have it) and ask for a repair exception, sometimes they'll agree to have the logic board replaced due to it being a documented problem. How true is this and who should I contact?
    Can anyone suggest anything here? If I can't revive the mini, I may have to drag my iMac back out and try to set it up to run OS X. I can't no where near afford another computer at this point. I'm praying the mini can be fixed. I would appreciate any and all suggestions!
    Thanks in advance!
    Tommy

    It does sound like the logic board has gone bad. However, there are no current repair extension programs open on the Mac Minis.
    This page lists the open extensions:
    http://www.apple.com/support/exchange_repair/
    So that's not an option. I assume that the Mini doesn't have AppleCare (whoops.), so I would not count on Apple covering it, but it's always worth a shot. You can call AppleCare (1-800-275-2273) or visit your local Apple Store

  • Intel Mac Mini stuck in reboot loop

    I just upgraded the hard drive in my 2007 intel mac mini core duo. Drive formatted successfully, contains GUID Partition Table.
    OSX 10.5 installed successfully.
    Machine rebooted, I ran software update to 10.5.7 successfully.
    Upon installing Adobe Flash Player, Adobe Acrobat Reader, machine began to react slowly to commands.
    Rebooted machine, went to Grey Apple Screen with spinning dash wheen icon.
    Machine rebooted itself, once again going to the grey apply screen with the spinning wheel.
    After about 15 minutes of letting the continual reboot cycle happen, I inserted the installation DVD for 10.5, held the power button in to power off the machine, and booted from the disk.
    I ran disk utility. Disk Utility shows the hard drive, shows the partition (GUID Partition) correctly.
    I Verified Disk, which verified as "OK"
    Repaired permissions.
    Restarted machine.
    Once again, it loaded to the grey apple screen, stayed there with the spinning dash wheel for about 3 minutes then continued to reboot over and over (everytime it reboots it sticks on the grey apple screen for 3 minutes before rebooting.
    I once again powered off the machine and reset the PRAM.
    Machine stuck again on reboot cycle.
    I powered off the machine and reset the mini's SMC.
    Machine is still stuck in reboot cycle.
    I have also taken the mini back apart and verified that all RAM and connections are seated properly.
    Any advice on what to do at this point will be very helpful.

    +And I promise I will not download and install a hundred different programs this time.+
    Good idea.
    Any time you install software in OSX, there is a small, but finite, chance that the installation process won't be able to access a needed file because it is in use. This can mess up pre-binding, or even prevent files from being updated.
    So the best advice is not to run any other programs while doing software installs or updates. And when in doubt, run DiskUtility afterwards and fix permissions one more time.
    I cringe whenever I think of a post I read a while back about a Mac user who boasted about what music he likes to run in iTunes while doing system software updates. Not a good idea. It's "Russian roulette" with maybe 99 blanks in the "gun", but one real bullet that can kill your Mac's installation.

  • Bluetooth Not Available on Intel Mac mini

    I keep losing the Bluetooth wireless connection between my Apple wireless mouse and keyboard and my Intel Mac mini (which is running Mac OSX 10.5.5)
    Tried re-booting but it doesn't always come back.
    Looked in System Preferences, but if the connection is lost, Bluetooth has disappeared as if not installed. If the connection is present then all seems OK. You can check battery levels etc.
    Left to itself Bluetooth can re-appear sometime later as mysteriously as it disappeared, maybe after half an hour or so. Very annoying as I have to result to using an Apple USB mouse and keyboard when the connection is lost.
    Tried running Bluetooth Updater but it says I haven't got Bluetooth if the connection is lost! But it came pre-installed on purchase. Problem only seems to have started since upgrading to Leopard. Never had this problem with Tiger.
    Any thoughts would be most welcome.
    regards,
    BJ

    Ok, I've resolved this on my machine, at least for the time being.
    Here is what I did. I am not advising anyone else to do this and I am in-no-way stating this will fix your problem. I'm just relaying what worked for me. If anyone chooses to try this then it's on their own head!
    I opened my Mac Mini and located the Bluetooth circuit board just in front of the rear power button. I removed the small phillips screw holding the board in place and noticed that the connector that connects the board to the main motherboard was not seated well. I removed the connector and reattached it, making sure I felt the 'click' as the connector was pushed home.
    I had also read on the net that the routing of the bluetooth ariel cable may cause problems due to interference from the USB ports. I took the opportunity to extract the ariel and run it over the disk and away from the USB ports. Before putting the lid back on I booted up to check Bluetooth was working again.
    So, I now have my Mac Mini with Bluetooth working again. We shall see how long this lasts - perhaps the root cause was a loose connection, in which case it may be fixed permanently now. I shall report back in a few weeks.
    Be aware that opening your Mac is going to invalidate any warranty. Mine was out of warranty anyway so I was not bothered. I've also got a degree in software and electronic engineering so know my way round the insides of computers. Please make your own assessment of your level of expertise before deciding to try what I did. It may not work for you anyway!

  • Intel Mac mini vs PowerMac Dual G5 storage server

    I would like to setup a server to store family pictures, iTunes purchases and other media. Also I would like to use it as a backup for important documents and data.
    I have a Intel Mac Mini 1.66 and a G5 PowerMac dual 1.8GHz.
    I have purchased 4 400GB drives and I am trying to figure out the best solution for the money.
    I would like to put the drives into external enclosures like OWC 2 drive FW800/FW400 and use the first pair as either RAID 0 or use the hardware spanning, and the 2nd pair as the backup.
    Will this be too much for the FW400 bus of the Mac Mini, seeing I also use an EyeTV 500/200 solution to capture TV and burn DVDs. I will do video editing, iMovie, iPhoto stuff.
    I would like to sell the G5, but would it make more sense to install 2 drives in the G5 and use 1 external enclosure with FW800 for the backup? I would like at least 1 external enclosure for the backup?
    Any suggestion would help.
    Thanks!

    I have both of the systems to which you refer. I am typing to you on my G5 dual 2 ghz. I have an older G4 dual with 4 drives in it that I use for backup purposes, I do not use a fileserver at home in the sense of what you are talking about. My mini is my entertainment system with 1 TB of storage, my purchases are made on the G5 then transferred to the mini (giving me a backup of all purchases) and the G4 is used to back up the entire library from my mini (not as often as I should though! )
    I know Wiebetech used to make an internal setup that expanded the G5's drive capacity from 2 to 4. While you said you wanted at least one external enclosure, that option would eliminate the need for an external case, another power cord, etc. so it may be worth looking into. I do not recall the name of the product but I know wiebetech manufactured it. Perhaps someone else knows the name or you could go to the company website. It is also possible in the G5 forum there is someone who owns the product as well.
    As to which one to use, selling the G5 and having just a 2 drive or 4 drive enclosure hooked to the mini is most certainly a significant space saver over the G5 (not to mention not having to either have 2 separate machines with 2 monitors, keyboards or a KVM or VNC type setup) There are many good enclosures on the market, not just single but multiple drive enclosures which could be a better/smaller footprint/economical way to go vs. 4 individual enclosures (again, wiebetech is a noteworthy manufacturer of such items...no, I don't work for them
    I too have eye tv hooked to the min as well as the 2 external drives I mentioned (250gb and 750gb) all via firewire. There should be no problem with the setup you mention as far as firewire is concerned and the mini. At least, not in my experience.
    Good luck, let us know what you decide and feel free to ask more questions. I will gladly help if I can (can't say I helped this time, probably gave you more questions than answers!)

  • Intel mac mini wont boot after system restore

    Hi,
    I ran the system restore on my intel mac mini using the genuine leopard cd that came with it.
    Now it wont boot. When you press power the light comes on but it does not chime and there is not video output to any monitor.
    Anyone know what could be wrong?

    Welcome to Apple Discussions!
    You picked 10.4.1 in your profile.
    Intel Mac Minis at minimum came with 10.4.4.
    If it came with a 10.5 genuine DVD, it most certainly was not running 10.4.1 or 10.4.4. Perhaps you mistook one Mac Mini install DVD for another? Does your Mac Mini have 4 USB ports on back? What does the 10.5 installer disc you used look like?

  • Intel Mac Mini fans run full blast even when off

    Hi All,
    I have gone through the forums and haven't found an answer to this one. I have an Intel Mac Mini running the latest updated Tiger that I use solely for a media center.
    About a week ago, the box started running fans full blast, regardless of whether it was actually turned on or not. As soon as it is plugged in the fans blast.
    Otherwise, it seems healthy, and boots normally.
    The steps I have taken so far include resetting permissions, verifying the disk, and resetting the SMC in the proscribed fashion.
    After this occurred, I downloaded and installed smcFanControl from Lifehacker.com. This reported fan speed of zero and Temperature of zero.
    Next I opened the case and insured the fan/HD cable next to the lttle battery was securely fastened as this had been reported to cause this symptom.
    What's next? The device is out of warranty and honestly, I don't want to spend any money if I can help it.
    Should I take it apart further and see if the other end of the fan/HD cable has somehow worked loose?
    Can anyone think of another cause besides a loose cable?
    What if I completely disabled the fan? The hardest thing I ever ask it to do is run iTunes and VLC.
    Any advice is greatly appreciated.
    Dave

    I have refurbished two G5s with LCS and screaming fans (this was avery common problem with G5 LCS macs), the red light on the motherboard could mean the CPUs need to be re-seated. This red LED light appeared on my mac after I had removed the CPUs to add new thermal paste.
    If you have done all the necessary basics with no sucess here are a few things to try next.
    1 - Coolant
    As BDAqua mentioned above, coolant evaporates and often leaks at the 'O' rings, to check this you will need to remove the CPUs from the LCS and check for crystalisation (white rice). If you have leakage, it will be time to drain the block, add new coolant and 'O' rings. This is tricky to do but there is lots of info here and on other sites to help you.
    2 - Thermal paste
    Replace the thermal paste with Artic MX4.
    Try the above and let is know how ou get on.

  • Thinking about switching to Intel Mac Mini... questions for the cognoscenti

    Greetings:
    I've been checking out the new Intel Mac Minis and I was thinking of purchasing one to replace my AV computer (PC) in the living room, which the GF currently uses. She's a typical user: watches video files/DVDs, uses iTunes excessively , sends web email and surfs the Net.
    I've fairly decided on an Intel Core Duo Mini. Since I know the basics about Mac, I had a few questions:
    1. What's an appropriate amount of RAM for a non-power user? Would 1 GB be more than enough or overkill? I'm used to running 1GB in a Windows machine. Plus, I'm also used to popping in memory when I needed to upgrade, and I see that's not really an option on the Mini.
    2. How would I integrate it into a Windows network? Would the Mini be able to share files with a Windows machine and vice versa?
    3. Regarding network integration: how easily would the Mini integrate into an existing Linksys 802.11g home network?
    Lastly, this isn't really an (easily) answerable question, but how easy do you think it would be for an average computer user to get up and running on a Mac after having used Windows machines all their life?
    Thanks, I look forward to your responses.

    Hello, I can only really answer Q's 1 & 3 as I've only owned a mini for the past 24 hours.
    I purchased the Single Core after taking advice of the Apple Store staff in Manchester, they were quite helpful. I only really produce music (have used Ableton, Acid Pro etc on PC for quite a while), surf the web, do my banking etc so was advised that the Single Core with 512mb would be sufficent. I work for an ISP and have 10 years plus knowledge of Windows but I was prepared to listen and learn having never used a mac before. From my own experience, I'm used to having to use a pc with minimum spec ie min 1.2GHz processor, 1gb ram in order to produce music without any pops or clicks (latency), though sound cards also play a part. I've also had to keep internet activity well away from any PC that I produce music on in that respect. Anyhow, I'm going off on a tangent here but I was playing around with garageband last night and I've never known music production to run so smoothy on 512mb RAM, never known it before so was extremely impressed and certain I made the right purchase opting for Solo Core. You may not actually NEED the full 1gb though this depends what you're doing. To answer your other question, my mac slotted straight into my home nertwork without making any additional configuration.
    i.e how long does it take to get used to a mac, I've found there is a learning curve but it's not THAT difficult, it's just the odd thing such as no right click of the mouse that takes some getting used to.

  • Normal + 3 chimes at startup with intel mac mini

    I posted this in the mac mini forum, but didn't get a helpful response. So maybe someone can help me here.
    I have a 300GB USB drive (formatted as Mac OS extended (journaled)) connected to my intel mac mini with the drive's power on all the time. When I start up the mini after the USB drive has spun down I get the regular startup chime plus 3 lower volume startup chimes. The activity light on the USB drive flashes during the 3 chimes. Then the system starts normally with the USB drive icon on the desktop. I can read and write to the USB hard drive with no problems.
    If I shutdown the mini and start it up again but now the USB hard drive has not spun down, I get just the normal single chime. Also, if the USB drive is disconnected, I get the normal single chime. I've tried a different USB port, but still got the same behavior.
    I've connected a USB flash drive, but it exhibits normal behavior, that is, just the single startup chime.
    Are the subsequent 3 chimes at startup OK and just telling me that there is an external hard drive? Or is there a looming problem? Has anyone else experienced this?
    Intel Mac Mini Core Duo   Mac OS X (10.4.7)   Apple BT Mouse & Keyboard

    Thanks. But the article says you won't hear the normal startup chime but some number of beeps if there is a problem with 3 beeps meaning no good banks.
    I hear the normal startup chime, then 3 of the same chimes but at lower volume. Must be something about the USB hard drive.
    When I bought the drive, it was formatted for windows with NTFS. I used disk utility to format is as Mac OS Extended (journaled). I've copied about 100 GB of data to it.

    Hi James, yes you can.
    Leopard requirements/10.5.x...
        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
    minimum system requirements
        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
        * DVD drive for installation
        * 9GB of available disk space (I say 30GB at least)
    Classic/OS9 Apps no longer supported.
    Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...
    http://www.ebay.com/sch/i.html?_nkw=mac+os+x+leopard+retail+10.5
    But if it's a better Browser you need, then...
    TenFourFox is the most up to date browser for our PPCs, they even have G4 & G5 optimized versions...

  • Intel Mac Mini & Speedtouch 330 USB

    Ok..
    I was delighted to have my mac mini shipped to me the other day.
    It took nearly three hours to do a migration from my emac.
    Then I tried to connect to the net using my speedtouch 330 usb.
    Doesn't work. Single red flashing led.
    Spoke to wanadoo, and speedtouch, both declare that speedtouch does not work with the intel mac mini (os 10.4.6). Need a router (which one?)
    Fact or fiction? I don't know.......
    Has anybody had the same problems with the same hardware.
    Any feedback would be ace.
    Cheers World..

    It might well be correct in that the driver may not be Intel compatible. What I suggest you do is go to the SpeedTouch web site…
    http://www.speedtouch.com/
    … and download the latest driver for your modem and see how it goes. I just checked and there one for Mac OS X 10.4.
    If it fails to work then you might just be stuck with an Ethernet modem/router. As for which one, the simplest, though not necessarily the cheapest, is to get one from Wanadoo as it will have a profile for easy setup otherwise you can get pretty much any one you like.

  • Dead Intel Mac Mini - any electronics geniuses?

    Hi all,
    Shortly after powering on my personal 1.66 GHz Intel Mac Mini last night it went straight off not to turn on again.
    It made the startup chime and began booting but that was as far as it got. Now completely dead.
    Luckily I am an independent Mac repairer and have access to a known good power supply so that was the first thing I checked but no luck - still dead.
    Have obviously reset PMU and SMC as well as every other trick I know but it resolutely remains lifeless.
    Have removed all peripherals (HD, SuperDrive, AP and BlueTooth) and shorted across the power button switch (just in case it was a duff button)
    I have arrived at the conclusion it is something power related - a dead GPU or CPU would usually still give a glimmer of life but there is absolutely nothing happening - plus the fact that it started to boot then went straight off rather than froze.
    I'm handy with a soldering iron and know how to use a multimeter but need a helping hand locating/testing for dead components at board level
    Does anybody know what component/components might be causing this? Any help gratefully received as always
    Ryan

  • Intel Mac mini memory question

    Hi,
    I got an Intel Core Solo Mac Mini.
    4 questions :

    2- Is it 2x256 mo or 1x512 ?
    3- I want to upgrade to 1 gig, do I have to buy 2x512 ou 1x1000 ?
    4- Does this ram is compatible ? http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=221705 6&CatId=2268
