400 and 500 Logic Boards

Are the 400Mhz and 500Mhz logic boards interchangeable? Can I put a 500Mhz logic board in a powerbook originally fitted with a 400Mhz board?

Yes, they are interchangeable. The only problem I can think of that you might encounter is that the installer DVD or CDs originally shipped with the 400MHz Powerbook may no longer be willing to install anything on it after the faster board is installed. If you have no further use for that disc, the problem won't arise, and even if you do, it may turn out to work just fine.

  • Are i5 and i7 logic boards in the 27" imacs the same? i

    Are i5 and i7 logic boards in the 27" imacs the same? i know that the i5 uses the 661-5429 p/n and the i7 the 661-5428 p/n but are they interchangeable?
    Do they have the same sockets?
    Thanks.

    Perhaps the best news to come out of Intel's new line of i5 and i7 processors is introduction of a single socket for all Sandy Bridge Core i3/i5/i7 processors...
    For now, however, the Sandy Bridge processors all use the LGA 1155 socket. In case you're wondering, this socket is not backwards compatible with previous LGA1156 processors - don't try it unless you like junking your hardware.

    Apple supports most of their computer products for a 7 year period, could be that your IBook is well past any kind of help.Secondly parts are no longer being made for this machine and never will be again. Finally I find it hard to believe that nothing has been done with this for 6 years.Have you documented the reasons why you were turned down for repairs ? were the replaced Ibooks within a couple of months of warranty expiration? What model is your IBook ? At least if we knew what the model #, some of the more techy types could find out if there were any repair programs for your model.
    Seems odd that you'd hang on to a non-working IBook for that long.

  • Freezing, Panics, and a Logic Board error

    Okay, I have a PowerMac G4 Gigabit Ethernet, and it's been crashing, giving me kernal panics, and today, toasted my main hard drive. It's running on:
    1.2GHz Sonnet G4 upgrade
    1.5GB Ram (2x256 and 2x512)
    Radeon 9800 128MB
    2x20GB hard drives RAID striped
    18GB spare
    combo drive
    2x120GB external firewire drives
    I can give more details if needed, but basically, if I watch TV resolution video with VLC media player it will crash after 25 minutes or so,if I run the iTunes visualizer for 15 mintues it will crash, if I play World of Warcraft for about 30 minutes it will crash, actually, if I run any graphically intensive game it crashes. Then today I ran the Apple update for the JSE (or whatever) and 10.4.6, then when I rebooted, it gave me a kernal panic, where the first line said something about not having the driver for "Powermac G4 3,3". Then I run Apple hardware test 1.0.1, I ran that 5 times, and the first time, I got the error "scc /3/7" every time after that I got "scc /1/5" all on the logic board, and it wouldn't test pass that. I do have the machine running but since I left my system disc at my parents', I'm booting it from another machine in target disk mode that has 10.3.9 (option-boot saved my butt, kinda). Last but not least, I cannot access my main drive (the 2x20GB RAID), and I'm hoping someone has a way to get to it, but every time I start, it tells me that I've connected a disk that is not recognized my Mac OS. If the drives are gone, I'll have to deal with it, but I can't have my machine freezing on me like this, and any help is much appreciated
    Gigabit Ethernet Powermac G4   Mac OS X (10.3.9)  

    Well after 5 tests and every time having the logic board fail I am willing to bet that the logic board IS the probable cause.
    What I would do is disconnect all the drives (minus the x2 20gig raid) and get the data off each one. If that other machine you are booting up in targeted disk mode has at least 1 open ATA66 slot free then you can simply change the jumper settings on each drive and get the data off. This will also give you a chance to test and verify each disk.
    If the other Mac you are using targeted disk mode on is a laptop then you could go the slower rout of taking turns with making each drive the master drive on the internal ATA66 buss that your machine started with. That way each time you start up with targeted disk mode you can get the data off that drive.
    Once all your data is off I would consider the cost for a replacement board (probably $3-500 is my guess) vs the cost of getting a new machine or simply a used newer machine (like a dual 1.2Ghz G4 or something allong those lines). The drives will work in the newer machine so there would be no costs in getting new drives compatible with the system. That is my thoughts.

  • Grey Screen at start-up - Troubleshoot harddrive and/or logic board?

    Hi everyone. Sorry for the lengthy post, but hopefully you can help me - I've spent a lot of time on the boards already, but hoped you could clarify some things.
    The problem is my Powerbook will not get past the grey screen at start-up. It will not boot off the 10.5 install disk and I can't eject the install disk to run the hardware test disk. Removing 3rd party ram, resetting PRAM, NVRAM, attempting to boot in 'safe' mode haven't helped. The harddrive is softly clicking/searching.
    So some questions:
    1) Is it possible that an interrupted time machine backup will bork the drive to the point where it wont boot? (See back-story below). I wouldn't have thought so, but prove me wrong.
    2) Should I be able to boot from the install disk if the harddrive is stuffed?
    3) If it is hardware, it's either the logic board or the drive. Is there any way to determine what it is (eg: is it possible to do a remote hardware test?)
    Edit: Just tried mounting the drive in target disk mode using an iBook, but it wouldn't mount. Powerbook displays a black screen.
    Oh, and I should point out that this is well out of warranty and any fixes would have to be cheap : ). Basically I need to determine if it's the drive or the logic board, preferably without having to buy and install a new drive when it may not be the problem.
    Any help or advice would be appreciated.
    Cheers
    - Ben
    Here's the back story if it's any help; recently upgraded to 10.5, created a base install disk image of all installed and registered apps (in the event that my drive failed). Copied data etc from the previous system over. It ran fine for a few days. This morning I ran time machine for the first time, left the computer for a while, came back and the screen was black (as if it was just displaying black, as opposed to off). Thinking it was just a display issue (which I've seen before), I put the system to sleep (power button, then 's'), woke it up again; still black. So I forced a shut down (wouldn't allow me to do a normal shut down, because dialogue boxes must have been preventing it) and on boot I got the grey screen.
    -------

    Hi Ben W. I don't have a good answer for you, but based on your information and what you've done, I think I would try starting the machine after disconnecting the harddrive. That requires taking the top off first, for which instructions are on ifixit.com.
    I can conjecture that a blown HD is preventing normal operation, perhaps sucking the power down, disrupting the optical drive, etc. This is purely conjecture, but costs you nothing but your time. If this turns out to be the case, I figure the optical drive should start responding again (hold C key during reboot, etc).

  • How can I tell if my motherboard and/or logic board is fried?

    Good evening all, I was just wondering if anybody can tell me the way to find out if my old power mac mobo is fried, or weather it's the logic board or the power supply. When I try to boot it up there is no start up chime, there is no white power on light and the red light doesn't even come on. It's one of those bad liquid cooled models but it hasn't leaked. I really don't have the luxury of spending a lot of money just to have someone diagnose the thing for me. I would be willing to replace the power supply for the price that was quoted to me off hand from an apple tech, but the person on the phone wouldn't let me talk to the tech so he wouldn't answer my ? and I despise the genius bar kids who don't seem to know the hard core techie stuff and I tend to talk circles around them. Sorry if there is already a post on this (I searched but came up with nothing) or if this is a dumb or fruitless effort on my part but no clear answers yet found in the magical internet.
    Cheers and thanks in advance for your responses!

    Can you count the beeps or flashes of the Power Button?
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
    5 beeps = processor is not usable
    In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
    Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

    TM makes a full copy of your hard drive. you can restore anything and everything you need from it. you can do a full system restore which will give you the exact copy of your current system or use Migration Assistant which will only copy the things you mentioned.
    P.S. TM does work in safe mode.

  • Final Cut Pro and New Logic Board

    I just got back my 2.4 ghz IMAC from the Apple Store, where they replaced the logic board. Before this replacement, I was able to capture via firewire into Final Cut. Now the programs stalls when opening the capture window. Can anyone help me try to solve this problem.
    Thanks

    well if you decide to do a clean install it goes like this:
    Backup all your data, everything will be erased (don't forget bookmarks, pop3 emails, FTP passwords etc) and de-authorize (or whatever they call it) Adobe Creative Suite if you have it.
    Boot from the OS dvd (hold down "c" key on startup {or option will work too})
    choose clean install
    Then run software update.
    Then install FCS, then run updates for that.
    After you get a nice, clean well running system, clone it (search the forum for "clone") with Carbon Copy Cloner, Net Restore, SuperDuper etc. You can then re-image your system in minutes, instead of a few hours.

    Normally those are page not found errors.
    I got the steps from metalink. See below.
    Subject: Changing the default error pages
    Hi,
    Steps mentioned below are used to have customize error message page for http 404 error,you can find out error no. for 'internal server error' and apply same steps.
    1.Create an HTML file (Say test.html) as per your requirement and place it in
    application_home\Apache\Apache\htdocs folder.
    2.Edit the HTTPD.conf file and Uncomment the Local redirects as follows
    # 2) local redirects

  • MacBook pro isn't even 2 years old and the logic board died.... Can apple help?

    Will apple replace or exchange this for me? It has never been abused, I treat it with so much care. I didn't even think about getting the extended warranty...I expect my computer to last longer than 2 years. Feel really let down by this.

    Sorry for your problems but, unless there's a known problem with certain problems, Apple will charge you to replace your motherboard. Next time, I strongly suggest buying AppleCare. I've owned Macs since 1985 and when AppleCare became available, I always bought it for any hardware device for which it was offered - and I believe that it is a particularly good investment for laptops.
    You should take it to an Apple Store and see what the price would be for the repair - they are often surprisingly reasonable.

  • Mid 2009 applecare logic board and battery ADVICE

    returning mac OS and mac hardware buyer here.
    i have been questioning (read complaining) about the battery life (1 1/2 hours on safari) and the performance (spinning beachballs on startup, on wake and on starting safari among other things) since i bought this machine. i brought it in for the umpteenth time to the genius bar (they apparently only have 3 of these on record?!) because i had a break and i have a "service battery" alert.
    i am being told i can replace the battery and the logic board based upon their diagnostics of the machine and i have FINALLY (Whoo-HOOO yippeee kayeeee'y!!) got a committment from a mac rep that i should be expecting  3 1/2 - 4 hours out of the battery and not 1 1/2 hours.
    i don't really have an option here from everything i can tell but does anyone have any advice for me on this? warranty is up in February and from what i am being told i can bring it back if i bring it home and still only get poor battery life.
    at the same time i am really unhappy (insert expletive) about having spent so much time troubleshooting this machine only to be told that the hardware seems fine or that the battery tests normal or whatever. this macbook pro 13 inch seems like it was a dog since the day i bought it.
    my preference would REALLYT be to trade into mac on a new macbook pro 15" and i am wondering if i am instead i am going to have to just repair this machine (thank my lucky stars that i buy applecare) and empirically test the machine on my end to make sure that i am getting more than 2 hours per charge and that i don't have the spinning beachballs that i have had to have dealt with over the last 3 years...
    i mean, i /have/ to fix this machine and monitor it over the next three months instead of them helping me cut bait with it by getting some financial incentive somehow to move into a new MBP is that right...?
    TIA

    thanks.
    looks like it has now had a new battery and a new logic board and it is still failing hardware test for the battery.
    they are now sending it out for additional testing to some other facility.
    anyone had a similar experience?

  • Hard drive and logic board failure

    Hi everyone,
    we have been suffering from 4 dead hard drives and one logic board failure in 20-inch intel iMacs (~2007) recently and last month the logic board and hard drive of a 2010 27-inch iMac (just out of warranty) just died.
    Are there any known issues with the iMacs that Apple fixes even outside the warranty?

    Frank:  I have a 5 month old 27" iMac and the logic board on it just died as well as I was getting all kinds of kerner errors.  I have Apple Care and although the cost to replace the product was $800 I am not going to have to pay anything.  I did talk to someone else who also had a logic board go bad on him but I doubt that you will be able to get it fixed without having to fork over $$$

  • Logic Boards, Serial Number, and iCloud

    I'm posting this because I want others who run into the same problem to find a solution - I had some difficulty pinpointing why I was having the following difficulties. Hopefully, if you're reading this, my experience will help!
    So, I have two iMacs - one is a mid-2011 model, one is the model before. I upgraded both to Mountain Lion with no difficulties. However, yesterday I began tooling around with iCloud on the newer model, and found that while some iCloud features worked - like Notes and Calendar - others did not, specifically, iWork. I have had no problems syncing files between my iPhone, iPad, and other iMac, so I've been able to retrieve Pages / Keynote / Numbers files with no problems. However, with the mid-2011 model, I was getting just an empty iCloud page.
    I did the basic stuff - ensured that I was signed into iCloud with the correct account, ensured I had fully-updated software, and the like - but still, I was getting no love from iCloud. I searched a few forums and checked out some ~Library folders, but everything looked correct - everything was mirroring my older iMac's setup.
    I initiated a call to Apple and the front-line rep had me create a test admin login to see if there was something wonky with my user file, but the problem persisted. (By the way, talking to a rep on the phone while they initiate a screen sharing program and following their red pointer around was great). The rep quickly bumped me up to a senior person, who investigated more files. And then we hit on the solution, one I didn't think to check out because it was so obvious.
    A few months back this iMac wouldn't boot up, and Apple replaced both the power supply and the logic board. However, the folks at the Genius Bar forgot to "re-serialize" my iMac - the computer was nearly fully functional, but didn't have an internal serial number after the logic board swap. It's like a two-minute step that someone forgot to do.
    I brought the iMac to the Apple Store today and in two minutes they had re-serialized the iMac. When I got home, everything was working as it should - the computer has its original serial number, and iCloud worked perfectly.
    So there you go. If you have some parts of iCloud working, but not others, check that serial number - iCloud uses it for some, but not all, functions. And if you're getting a logic board swap, verify that your iMac has been re-serialized. It'll save you a trip later on.

    Great that you found the solution!
    Make sure you unmark this as a question though.
    Regards!

  • Macbook won't wake from sleep - replaced logic board and batteries already

    I have a 13" White Macbook on 10.5.5 that occasionally won't wake from sleep. This will happen with nothing plugged into the Macbook except for the AC adapter. I have done the firmware upgrade, reset the SMC, reinstalled Leopard from the DVDs twice, brought it into Genius and had the ram, sleep switch, and the logic board replaced. There are no bluetooth devices attached to the computer.
    I've searched the forums but haven't found a definitive answer yet.
    Message was edited by: multiphrenic

    I've experienced the problem as well. I have the new aluminum macbook with all factory specs and no mods, except that I changed it from smart sleep to the original old mac behavior of instant sleep. It is intermittant and with mine, I've noticed that when the screen is open, the computer appears to be completely off, but when I close the computer the light on the front of the computer comes on. The only resolution I've found so far is to hold the power button for 5 seconds for a hard power down and then push it again--everything works fine.
    There is indeed a sudden drop sensor, and in fact, it did happen after I accidentally hit the corner of my mac once on a tv while trying to set it down. That could be the answer...we might have to try disabling that because quite honestly, if I drop my mac while its on, I'm going to be more worried about the screen, the case, even the cute little plastic apple than the hard drive (I have backups galore).
