I have an iBook G4 pre intel (the Mac store guys tell me) that the logic board is probably shot. I want to get all of my data files off of the hard drive with the ability to move them to a (non-Mac) laprtop I'm getting from my dad.
View 1 RepliesI 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 spilled coffee on my MacBook 8 months ago. It eventually recovered and operated without a hitch until yesterday when it would not boot up. I took it to the Apple store Genius Bar and they told me it was residual damage, probably to the RAM and logic board. Cost to fix: about $850. Anyone know of someone who can fix this reliably for less? In the Stamford, CT area or New York City?
View 4 Replies View RelatedThe logic board on my powerbook (aluminum)G4 is fried. I would like to get the data off the drive, but would like to do it myself. Will the drive plug into an external carrier rig like any other drive? I have a granite digital external firewire drive caddy rig. I assume that the mini drive in the powerbook will not plug into an enclosure that was made for a regular drive? Are there any adapters for this sort of thing?
View 2 Replies View Relatedso 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]
My iMac G5 is basically dead. Logic board failure. Apple is going to replace it by giving me a credit toward the purchase of a new iMac but that is a different story. I need to send my G5 back to them. Can I take the internal hard drive out and transfer the data to a PC and then get that data off the PC onto an external HD?
So I took my MBP into the apple store today and explained that my original hard drive was showing as failing after my two momentus xt drives were apparently failing as well. He said it was really strange and hooked up the drive to their external interface and low and behold there was no errors on the drive. He said it's most likely being caused by IO errors due to a bad SATA cable or possibly logic board. We had my MBP sent in for testing. So basically if you see SMART failing status it may not be the drive after all.

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?
View 5 Replies View RelatedI have lost all my data from my harts drive. The laptop is under warranty. I have been told that they have replaced my hard drive but could not get any data off the old one. I have now lost all my data, photos, files, music etc. NO backups, only simply because i did not know how to do them. Is there any way of getting the files back? All my work spreadsheets and accounts were also lost.

MacBook Pro (13-inch Mid 2012)
Anyone know where I can get it cheap ?
View 24 Replies View RelatedI 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.
View 1 Replies View RelatedSome 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.
View 5 Replies View RelatedWas 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?

View 14 Replies View RelatedI'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?
View 7 Replies View RelatedI bought my first Mac (iBook) last December. However, it is now dead from logic board failure. I was looking at Macbooks but they are very expensive, which is why I bought the iBook in the first place. So now I'm looking at 15" PowerBook G4. My question is: If having a G4 proves too difficult in the next few years (PowerPC compatibility and speed), could I put a logic board from a 15" MBP in the PB?

View 1 Replies View RelatedMy 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?
I have a Rev. A 1.83ghz MacBook which my partner uses. In the last six months we have had an increasing number of problems with it. First, there were the intermittent sleep problems: delay going to sleep, failing to wake. Then it killed three batteries consecutively before Apple replaced the sleep switch and power connector unit (thank heavens for AppleCare). That was back in July. Now the same problem has recurred: the battery is dead and fails to accept charge. Got a call from Apple yesterday to say that they've switched out the logic board and that the item is ready to collect.
We have eight months left on the AppleCare and what I want to know is:
1) What exactly can we expect from a logic board replacement? Do Apple really have a stockpile of 1.83ghz logic board's floating around in case someone needs a replacement or is there any chance of a processor upgrade with this repair?.............
I have this logic board listed on eBay, and a person has asked me about the bus speed. The logic board has already been parted out from the computer. How/where can I get this information?
View 1 Replies View RelatedAs the title implies, I've got 3 year old G5 iMac sitting as a paperweight at my desk. At least half that time ago the logic board died and I was quoted a repair bill of around $900. I couldn't go with it, but I couldn't decide what to do with it either. I now have to get rid of it and since I know that this model had lots of issues with logic boards I'm hoping some of you will have some good advice.
I want to swap motherboards from one machine with cpus attached to another machine.
Is it difficult?
I have a 2.66ghz case that got damaged and I want to put the upgraded processors/logic board in my case.
Would it be easier to swap cpus or logic boards with cpus?
How do I determine what logic board is in my machine, i.e. manufacture, ports , speeds etc.?
