1st Generation iMac G5 with new main logic board but now no Bluetooth?

Greetings:
As an owner of a 1st generation iMac, I can finally report that my iMacG G5 is now working fine since the main logic board has been replaced because of bad capacitors.
A NEW problem has been created. My internal bluetooth no longer works and is not visible in the hardware profile. I suspect that the Apple repair center may have removed my module or that it was attached to the old main logic board. On PC's running MS Windows (XP), there is a "hardware detect" routine.
QUESTION: Can anyone tell me if the internal module is visible by taking the cover off? I cannot seem to find a photo of where or how the module is attached. I can see my Airport module. Regardless, the Apple repair center said to simply bring it back in and they would fix the problem. They indicated that it was a simple software fix. After trying many different software techniques, I still believe they somehow forgot that my computer had BT and it went back with my old logic board.
Thanks in Advance,
Jeff

We discovered the problem. After taking my iMac G5 back to the Apple service center, I got to observe the technician remove my G5 cover and bluetooth module.
The problem was due to the fact that the initial technician apparently did not realize he/she broke off the very small connecting pins on the module when he/she removed it from the original main logic board with the bad capacitors. They simply screwed it on the main logic board. They order a new BT module to replace the broken one.
FYI: It is very easy to install the BT module on the main logic board as I observed. No soldering, etc.. The location is directly above the power supply but below the airport card. It is about the size of a postage stamp and is in clear view withou removing any parts.
Thanks to All....Miriam...

  • New main logic board...my findings...

    So I just received my MBP back from AppleCare.
    Whine: it's almost completely gone.
    Heat: slightly better, if at all. Idles around 60C and I just put a load and got 88C.
    Other: now there's a rattling noise in the fans. It's slightly audible when the fans are on low, but when I put on a load the rattling noise becomes quite loud.
    Guess I'm sending it back again.

    Sorry if I confused you, I am sending it back. I'd posted a followup message that I realized was inaccurate.
    The tech said he couldn't guarantee the heat would be fixed (roll) but at this point I don't care. I just want to have my MBP back and working.

  • I bough a refurbished iMac last year, unfortunately Im in need of a Logic board, but when I search FD093LL/A, no company seems to recognize this model but I do see all models, or at least most, starting with MD...whats the difference?

    I bought a refurbished iMac last year, unfortunately I'm in need of a new/used Logic board, but when I search and contact Company with Mac parts, no one seems to recognize FD093LL/A witch makes it tough to identify parts, but I do see most Part Numbers starting with MD. Any reason why?
    Thank you

    Refurbished models have a different order number. Replace the F with an M and see if the specifications listed match your computer’s.

  • Problems after Replacing the Main Logic Board in E280R

    Hi
    I have just replaced the main logic board and FCal Disk Back plane in one of our E280Rs and now we cannot get any out put to a console (or to RSC card). So cannot get to the OK prompt or any diagonistic output. There are no errors according to the system lights although the RSC card is reporting faulty internal disks. Whether the disks or working or not we still should be be getting at least to the OK prompt.
    The main logic board has the same part number as the one we replaced and we swapped the old SEEPROM chip to the new main Logic board
    Any Suggestions greatfully received
    Thanks
    Rob

    LowLuster is correct.
    If Apple techs are talking about replacing the logic board, the costs of doing so is over half the cost of a newer IMac.
    You maybe better off, if it is financially possible for you, to purchase a new or "newer" used or refurbished iMac.

  • Help! I have had my iMac G5 fitted with new Logic Board but it doesn't work

    Help! I have had my iMac G5 fitted with new Logic Board but it doesn't work
    I have just had my iMac G5 First Gen 1.8Ghz fitted with a new Logic Board under the Apple Repair Extension Programme for iMacs.
    I got the iMac home from the repairers and switched it on and everything was working fine for about 2 hours and then all of a sudden the Error Page came up on the Screen (with a big On/Off Switch Logo) and it said I had to shut down.
    So I shut it down waited a few minutes and then tried to re-boot it but nothing happened. All that happended was the Power Light in the Right hand corner came on..but nothing else....
    Help! Any ideas what to do please?

    If you have an external firewire drive (it has to be firewire, USB won't boot on a Rev A), plug it in to the firewire port and turn it on, then boot your iMac and see if it shows on the screen.
    Have you tried to hit the eject (up arrow, the last button on the top row of the keyboard) button when you boot, perhaps the repairers left a disc in the drive? Then try and put your install disc in.

  • 1st generation iMac G5 won't start up with LaCie connected

    Sorry if this has been asked a zillion times, but I am trying to help a friend (as you can see it is not my iMac):
    She has a 1st generation iMac G5, and a LaCie external harddisk connected by firewire. The LaCie has an independent power supply, i.e. not powered by firewire.
    Her iMac starts up fine when the LaCie is NOT connected, but refuses to do so when it is. This problem did not always exist.
    Does anyone have the answer - better still a cure?!

    Is the LaCie on and showing on the desktop when she shuts down? It's always a good idea to eject FW drives before shutting down, and to start up with them unplugged, otherwise data corruption can occur.

  • How do i go wirelss with a 1st generation imac that is not airport enabled?

    Hi there
    Does anyone know if it possible to go wireless with a 1st generation imac that is not airport extreme enabled?
    Thanks for your help

    It's not a bridge. It is simply a ethernet to 802.11G adapter. It is just a different way of adding wireless to a Mac.
    The Airport Extreme card is just $49 and it is internal. It is not hard to add at all to your first gen G5 iMac so I would go that way.

  • Help - nonworking 1st Gen iMac 20" with bulging caps (power supply)?

    I have a 1st Generation (Rev. A) iMac G5 that does not power on. I looked at the logic board, and all of the capcitators appear OK. None are bulging. Most have a "K" on them, some have the infamous "X."
    I took my iMac into the Apple Store Genius expecting to be covered under one of the iMac G5 extended repair programs for out of warranty iMac G5s:
    http://www.apple.com/support/imac/powersupply/repairextension/
    http://www.apple.com/support/imac/repairextensionprogram/
    I did not qualify for either, as the one is only for video AND power issues, and the other only for Rev. B iMacs.
    So I took my iMac home looking to buy a power supply. I took the power supply out and opened it up and found all "X" capacitors, some of them bulging.
    So what is my next step?
    • Should I phone Apple Customer Relations at 800-767-2775 or Executive Relations 800-275-2237?
    • Should I take the power supply back in and show this to the Apple Genius and explain my situation?
    • What about the logic board? Should I demand Apple replace that too, since it has the X caps?
    I am out of warranty and no AppleCare. But according to other threads, like this one, this is a known issue and Apple should replace both my logic board and my power supply. But the genius I dealt with this morning seemed very knowledgeable and said he has been working on Macs for 20 years. He actually checked in my Macbook with a couple of issues and is resolving them no problem. But no joy on fixing the iMac.

    I took my Macbook in yesterday for video flicker and misbehaving battery. Received new battery, logic board, and inverter cable in about 32 hours. Kudos to Apple for fixing my in-warranty machine so quickly and not blinking an eye. The Genius who checked in my MacBook asked if I read about these repairs on the web, as he said it is a major problem. Ironically, since then I have been cautioned twice by Apple about what I read on the web.
    What does that have to do with my iMac saga? Absolutely nothing, other than since I went to pick up the MacBook, I took the iMac back in. Plus, I am trying to find some words of praise with Apple's prompt, no-hassle repair as with this iMac issue I can find no words of praise.
    I started out with this new Genius tonight by explaining I brought in the iMac yesterday and the Genius didn't even open my iMac but just checked the serial number and EMC number and must have been confused on the programs. I told him he denied me either program and said the one issue was for Video AND Power issues, and since I did not have a video issue, I was denied. I was asked who helped me, and gave his name, and I could tell the genius in front of me regarded him highly.
    Anyway, they brought out the MacBook, I signed for it, put it back in my laptop bag. Attention turned back to the iMac, and I could just sense a reluctance to help me. I had mentioned that there were X capacitors on the logic board, but that none of them were bulging, and I had read that could be a problem in the future and that people were getting logic boards replaced even though the problem was with their power supply and the logic board appeared fine. I received the party line again about misinformation on the internet and not believing everything I read. At least I convinced this guy to open up my iMac, which he would not do in front of me but took it into a back room.
    He came back out and said my capacitors were fine and there was nothing he could do. (Well, I had already told him they were fine.) I said that this was for power issues and the problem is obviously with my power supply and he said he could not help me with that.
    I was/am very ticked off and just didn't feel like getting into it. Normally I would have asked for the manager. The genius wouldn't even look me in the eye. I feel like I have leprosy or something. Has anyone else with a Rev. A iMac with serial numbers for this program get denied? I have not read such a thing on this forum. Someone please post a link to comfort me so I know I am not the only one.
    I just left, in defeat. I've got enough Mac service centers around me that I am going to take it to one of them. In fact, I DID take it to one of them first on Monday morning, but didn't have the original receipt with me, so they said that could be an issue, so I just left and took it to the Apple Store since I was already out that way.
    Maybe tomorrow I will find comfort back in the arms of one of those hybrid computer stores. The saga continues...

  • What do they replace a 1st generation ipod nano with now?

    What do they replace a 1st generation ipod nano with now? from the recall.

    Glad you were able to sort it out - iPod cables and USB ports can sometimes by mysterious in their variability - though in your case the symptoms suggest that a conductor may have failed inside the cable you were using.  I've found that, using a selection of cables:
    my 2G nano will occasionally be detected as being connected via USB 1.0 (even when connected to 2.0 ports)
    my 3G nano syncs fine but steadfastly refuses to charge when connected to any of the USB ports on my main computer, though using the same cable charges happily when connected to a USB AC adapter
    Such things are just sent to annoy us
    On your other question, it is possible to completely replicate your library across two or more PCs.  As long as the iTunes database (iTunes Library.itl) is duplicated as well as all your media you then have two physical copies of one logical library, with which iDevices will sync on either computer.  See turingtest2's notes on  Make a split library portable to see how to verify that your library is in a consistent structure to make replication easier, and Backup your iTunes for Windows library with SyncToy on one method for replication (typically using an external hard drive that also serves as a regular backup).  My configuration looks like this:
    where the library on my "master" system is replicated, using MS SyncToy and an external HDD, to two other systems - a secondary one at home and one in my office at work.  My iDevices will sync to any of these without the "threat" of wiping their content because iTunes detects that they've been previously synced to a different library - because of the replication method used the "unique" library identifier that iTunes uses in the sync process is actually the same on all three systems.

  • How can you transfer files from an iMac with a bad logic board?

    This is in reference to my "Nothing but a blue screen at startup!" post. He took his iMac to an Apple authorized repair shop and he was told that the logic board was shot. He has decided to get a new iMac but he's wondering about all the photos and other files he has on the old hard drive. What are the ways that he can get files from the old hard drive on to his new one when he gets it? Thanks in advance for your help with this!
    Eric

    Hi Eric!
    roam's method is a very good one!
    I don't know if this will work because of the bad Logic Board, but another way, may be to use Firewire Target Disk Mode.
    The ailing iMac would have to be Firewire enabled, and you would need access to another Firewire Mac.
    Good Luck!

  • IMac G5 serial number missing after main logic board replacement!?

    After replacing the main logic board on a 15-days old brand new iMac G5 2 GHz 20-inch TFT, the computer serial number no longer shows on" Apple ()/About this Mac" or on "System Profiler/Hardware Overview/Serial number".
    As far as I know that is normal, but my question is: is there a way to show the serial number (old or new) again? Resetting the Firmware perhaps?
    Thanks.

    I got a new serial number sticker to put on the stand base. It also inckuded the new MAC Address for network use.
    I would call and see if they can send you one.

    Hi mshields1162,
    Great question, and welcome to Apple Support Communities.
    First, you may want to choose to have the sidebar displayed for familiarity:
    iTunes 11: Frequently used features
    http://support.apple.com/kb/HT5649
    Afterwards, your device should be displayed if connected:
    We'll want to click on it, and choose the Music tab at the top. Let's make sure "Sync Music" is checked:
    Afterwards, you'll have the option to sync either the entire music library (for your first iPod), or "Selected playlists, artists, albums, and genres" (for the secondary device). Upon selecting this option, four larger option boxes will appear allowing you to pick and choose what content will be synced. For audiobooks, you may need to do the above in the "Books" section. For a visual instruction on how to do this, see the following:
    iTunes 10: Sync to your iPod

  • I have a 1st generation Time Capsule with current firmware. Can I define the time periods when my children's devices have access to the wi-fi network?

    I have a 1st generation Time Capsule with current firmware. Can I define the time periods when my children's devices have access to the wi-fi network?

    Can I define the time periods when my children's devices have access to the wi-fi network?
    Yes, using the Timed Access feature in AirPort Utility, you can setup specific rules for each wireless device which define the exact timeframe each day that the device will be allowed to connect to the wireless network.
    Example....junior's iPhone can connect.....
    Everyday......Between.....9 AM and 10:00 PM
    or
    Weekdays.......Between......4 PM and 9 PM
    and Weekends.....Between......9 AM and 11 PM
    At the same time, your own personal devices will have Unlimited Access at all times.
