Intel Mac :: Should Replace A Logic Board In My 2009 24" ?
May 27, 2012
My fan(s) started running at high speed and display was erratic. I diagnosed a thermal issue with the logic board, tried some home troubleshooting, then took it in to the genius bar. Fans checked out fine but logic board (and maybe video card) did not. Repair will be north of $600. Problem is, I love the 24" iMac and don't want the 27" and wouldn't want to go back to the 21". Would it be dumb to fix a 3 year old iMac.
I'm somewhat new to the forums, and found a really good deal for a brand new macbook air (rev.1). I'd like to know if it is possible to replace the logic board in my macbook air with a newer, nvidia-gfx based logic board. As in, will it fit, does the same power supply run it, same peripherals (airport, keyboard, etc) work/interface with it, etc?
My computer recently, today, got a problem where the monitor no longer works, and an external monitor doesn't work. Thought it was maybe this can't get out of sleep problem, but it's not.
A shut down and restart, battery removal, connect a another monitor does not do anything. It seems to work fine otherwise.
Took it in and they said the entire logic board had to be replaced, and would be $1,300. owwww.
Is this reasonable? Anyone have a cheaper way to go about this? This is a 2.4 MacBook Pro. Another option, I would hate to do without my computer for a length of time, but $1,300 is money I really don't have now.
I see in the Buyer's Guide another incarnation of the MacBook Pro is coming. Does that mean the price of my logic board would drop soon?
My IMac would turn on I would hear the fans spin/whirl but know "ping" noise to tell me it was powering up. Screen was dark.So I replaced the power board. This did not work. So now I've been told that the logic boad needs to be replaced.
I have a first gen Mac Pro - late 2006 I think - and one of the processors died, making it one hell of a paper weight. The authorized Mac tech has told me he has to order the entire logic board with processors b/c you can't just replace the processors. Googling tells me otherwise.
Basically it's $700 for the parts - is this the route I have to go? Is that a good price? Can I upgrade processors at this point?
If I got a first Gen 17" MBP, could I replace the logic board with the last gen (non unibody) logic board?Was the casing of the "classic" MBP unchanged from the first gen to the last generation?
My Mac Pro 1,1 has been diagnosed to replace the main logic board at a cost of just over $600. Is there a reliable place to send the logic board for repair? Or should I spend the $600 on a refurbed board or sell it and replace it?
I came across a powerbook g4 (dvi, 15 inches, 800mhz, 512mbs, airport card, dvd-rom + cd-rw, after market battery never used and after market ac adapter)) sold "as is" on craig's list. I picked it up for $50. It had everything but the hdd. The first time i plugged it (without hdd) I got the flashing ?. I swapped in another hdd and all I would would get the apple chime followed three soft beeps (nothing on the screen). And then eventually, I would power it on and the only sign of life I would get is the caps lock light on, and the num lock light only if I hit F5 (again nothing on the screen). If i let the powerbook sit without the battery for a while, then I would get the apple chime again but then the power cut out right away. This happens with the adaptor or the battery only which leads me to believe it's not the dc-in board. I have tried different ram, disconnected the airport card, disconnected the cd player. I have tried resetting the PMU and every key combination to reset the PRAM (it never seemed to make a difference).
Taking my mbp to apple store to get my gts8600 vid card fixed or somehing and they gotta replace the logic board. i heard on here it takes a few hours but the guy said 3-4 days?
I bought a refurbished first gen MBA about a year and a half ago. (It's under applecare for another 1.5 years). I have had terrible problems with video playback and trying to do the even most mild editing in Aperture and iMovie. Also, the screen is sometimes scrambled: Black chunks will appear like holes in the desktop image; The menubar will get scrambled; or safari will have weird misalignments around the toolbar/url.
Apple replaced the logic board about 6 months ago. I've continued to have these problems. I took it to the genius bar again today and the rep told me it was a problem with the graphics card and that they would replace the card. Then he said the logic board would be replaced since the logic board is fused to the video card.
That confused me. If the card is fused to the logic board, then it must have already been replaced the last time. He agreed, but at the same time assured me that this time it would somehow be different. I wasn't going to argue with him, but I have low expectations for any real results in improving performance.
Can anyone clarify for me what he was talking about? Am I wrong to believe that a second logic board replacement (and thereby a second graphics card) will solve the issues I am having?
Is it possible to replace the logic board in a 12in 700mhz g3 ibook with a g4 12in logic board? I was just wondering because I came across a g4 logic board.
so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.
i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.
i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.
the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.
i cant find anything on that model, except for on ebay.
and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]
i need some advice on what to do next, my Intel 24" iMac has failed, diagnosed as a faulty logic board by the Apple Genius. I purchased the iMac in Dec 07, and I deliberately did not purchase the extended warranty as this is a desktop unit, that in 20 months of ownership has never been moved, dropped or transported anywhere.
I have no option than to either pay for the repair - �380 or sell on eBay for spares...!
I informed Apple about the Sale of Goods Act, and they have put the owness on me to prove it was faulty from date of purchase...! They have informed me that I need to visit an Apple authorised service centre where they will run a test and produce a report, which will determine if the fault was there in the first 6 months of ownership.
can I replace my HDD in my late 2009 iMac myself? The current drive is toast and I've heard that late 2009 Apple started using HDDs with thermal sensors.
I have a macbook pro 17" 2.4GHz (non unibody). I accidentally applied 220 VAC to DC adaptor terminals and burned the logic board (and also the fuse on the left I/O board).
There were no visible damage on the logic board so I assumed only power input stages could have burned and started to investigate. I removed the battery charger IC, some burned mosfets; and I connected the adaptor plus input to the output of the battery charger block. So the DC/DC converters are now powered from the adapter, as in normal operation. Only difference is that there is no battery or charger stuff.
Now, when I press the power button nothing happens. If I connect the adaptor while pressing the power button, hold it for a while, release it, and press it again, it powers up. (Is this MCEverything from hdd to dvd to fans powers up but not the LCD. Fans start and remain running at full speed. Harddisk powers up but there are no noticable reads. That is, no os boot attempted. The mbp draws around 1.5 A to 1.75 A at 18.5 VDC(not sure if it indicates anything).
I'll do whatever I can to fix my board. I have MSc in electronics, skilled technician friends, and access to lots of tools, parts, and measurement devices.
I just got a Dual 1 Ghz MDD. It's a big step up from my 500 Mhz Sawtooth!
The problem is that it (supposedly) needs a new logic board. I've been watching logic boards on ebay, but I'm not finding anything with matching part numbers. My logic board has the following numbers:
630-4373 EEHNNW 448F2 KD2370366NFGA 630-4269
I guess the important numbers are the 630-* numbers. Perhaps one it the 'as designed' rev part number, and one is the 'as manufactured' rev part number?
I have the dual 1 Ghz processors; would they work on a 1.25 Ghz logic board? Most of the boards I see on ebay are 820-1476-A, or 820-1308-A. What's the difference between the 820- boards and the 630- boards?
I don't have a complete service file for the MDD; can anyone email a copy?
Anyway... I was planning on getting my hard drive replaced because it was making that weird noise I talked about and I still am... but. Something else happened to. My friends dog chewed my power cord (just a few bite marks) and it was enough to make the green like really dim so we unplugged it. Instead of trying to fix the cord... we just got a new one but the computer wont turn on! The light does not turn red green or orange on the plug but the battery light blinks when I unplug the chord (the battery is dead.. all drained i mean).
Me and my mom took the computer to a store that does warranty repairs on both Macintoshes and Windows computers and they said they would replace whatever for free. Like the harddrive maybe the battery if that is what is wrong and the logic board. But well... we kind of never told them my friends dog ate my first power cord >>
I wanted to. but my mom and my friend said they wont replace it for free if we told. I sure hope there is no way they can find out of the 1000 for a new logic board is true. We dont even have that kind of money right now!
But do you think the couple seconds of not enough power from the chewed cord might have shorted out my psu or something?
Im just curious. I know my friend has a friend that took his laptop in for a similar problem... yesterday or the day before.
After my MacBook Pro 2.5's logic board failed( and was replaced under AppleCare) after owning my MBP for just 17 months, activity monitor often shows asl ( system log file) manager at about 100% CPU. Fans spin at 5000rpm. Never had this issue before the logic board replacement. Also, Safari 4.04 frequently crashes; never had this issue either before, either. Occasionally, after restarting my MBP, the Apple doesn't appear on my screen but instead I get image of a folder alternating with a question mark. When trying to use installation disk to start up, under 'select the system you want to use to start up', Mac OS 10.5.8( the OS that's on my hard drive, will not show at all...it's missing. After restarting several more times with installation disk OS 10.5.8 eventually appears as a selection. Why would these issues appear only after the LB was replaced. I suspect that the replacement logic board or its installation is not 100%. Something's not quite right there.
Some of you probably will remember my post a week ago, saying that my MBP DVD drive killed my OSX Installation DVD. here is the conclusion of it, I took it authorised service center here in North Thailand. Waited for a week they sad they will change DVD drive and today it finally arrived. Around 11am they called me and said dude, we changed the drive the problem is still there cant install system. Your "Logic Board' is screwed, you have to wait at least 1 week for a new one.
Now what is logic board? Is that main board? Is it possible for computer to still work with a broken mainboard? I mean I didnt damage it, I had kernell panic and tried to re-install OSX so how could that killed my MPB? I still could boot into disk utility and format the drive was just unable to copy files.To be honest my MBP is 3 months old, i took a good care of it. And I'm very very very dissapointed in apple computers now, expensive and damn un-reliable.
Would it be possible to get a logic board with a 1.33ghz or faster processor out of a 12.1" G4 and swap it in to a G3? Are the parts even compatible? I know from building engines that certain years and parts are interchangable but I don't know about computers.
Was watching a 720p HD movie on a plane. Movie starts to freeze up. I can move the mouse but the rest of the computer is unresponsive. I force shut down by holding the power button.
Upon restart, all seems well, I login but computer quickly becomes unresponsive again. I force shut down again.
Next restart is over 10 minutes. Gets to login screen but can't login.
I boot from install disk and run HD repair. It finds some problems and repairs them. Reboot. Same symptoms.
I decided it is the HD and archive and install. Install fails. I wipe the HD cleaned and reinstall osx.
All seems fine as I go through set up and login in. A few minutes later same unresponsiveness.
So finally I did what I shouldve done awhile ago which is swap my current hd with my old one. I do and the computer runs fine! I'm at my wits end.
Just so everyone knows, the day before all these symptoms started I swapped my stock 2x1gb ram for 2x4gb ram. I originally thought that was the problem but I've had my original ram in since I've been trying to diagnose and it's made no difference.
I have an A1260 that looks like it's undergoing the problems repaired by this program: [URL] However, I've had this thing apart, replaced the hard drive with an SSD, the optical drive bracket is very bent from when I replaced the optical drive, my display bezel is cracked in two places and held up with duct tape, and it generally looks like hell. Will they still repair the logic board despite all the other, ahem, modifications? I could probably put the original parts back in, but despite that it will be obvious I've taken it apart. It is and was out of warranty when I performed these. Should I take it to a retail store or just call Apple and ship it to them?
thread or youtube walkthrough for removing a G4 MDD dual 867 logic board? (including how to remove the CPU daughter card).I have the heat sink off and all my RAM and PCI cards out,.
I'm looking fore some help/opinions on a friends iBook G3 800/30GB/256MB/10.2.8the problem is- when you press the power button, it powers on and you hear the (all is ok) chime. now sometimes it will boot perfectly fine and others you get nothing, just a blank screen.Now i know these things were notorious for logic board failure, but could this just simply be the HD, and if it is, how easy is it to change.
I'm still working on this deal to buy a used 12" PB. The seller says that she just replaced the logic board, hard drive, and battery. Now, I see this as a negative. Obviously the computer was having problems, she spent a bunch of money fixing it, and is now selling it anyway. What do you think? Is it a negative that it had problems and needed to be fixed? Or is it a positive that it has a brand new logic board that will theoretically last longer than an original one?
