PowerPC :: Power Button Cord Connector Broken Off EMac Logic Board?
Nov 28, 2009
I was attempting to replace the hard drive in my eMac, but for instructions I HAD to follow some darn take-apart guide that said pull out the connection for the power button cord from the logic board. I didn't know that it was SOLDERED in there, and now I can't complete putting my eMac back together without doing so.
Can this be fixed without having to send it to Apple? Does it HAVE to inolve soldering, or is there an alternative? Is there a way I can temporary have my eMac power on until I get the connector fixed?

I just bought a new Logic Board for a 1.25Ghz eMac and I've put almost everything back together after installing it until I ran into a problem. The power button cable that runs from the power button on the casing into the logic board has no connector on the Logic Board itself, now I have an old logic board that whilst being broken has a connector on it but I really don't want to have to solder the connector on for fear of breaking the logic board.

I brought my powermac into the apple store to confirm what I already thought - the logic board on my g5 is done.I'm putting it up on CL with full disclosure, but I was wondering what I should ask for it? Here are the specs, what would you pay?
powermac dual 1.8 g5
2gb ram (512x4)
80gb HDD
ATI Radeon 9800 XT 256mb
superdrive

I'm looking to get this titanium powerbook but it has a broken screen, possibly bad backlight? I can get it for a good price and I would love to have it to replace my ibook. I don't know the specs for sure but I am positive I think it's the DVI version since it has the keyboard that looks like the ibooks(same placement for the keyboard release latches).The guy said it worked fine on an external monitor but just recently he said it won't boot now and it now makes a high-pitched whining sound. Anyone know what that is? I'd like to use it as a headless mac until I locate a new screen for it.

My sister has just broken off the central pin to her iBook G4 which is now wedged inside the connector. Obviously the ac adapter is screwed and needs replacing but short of pulling out the offending pin from the inside of the connector, would I have to replace the power supply? How complicated is this? Cost? Any guides etc?

I recently had a problem where my 13" 3 yr old macbook would just blink off. then it became shorter and shorter until it would not start up. i brought it to apple who told me after inspection that it had liquid damage and the battery connector and logic board needed to be replaced for an astounding 800+ dollars. the book only cost me 1100!! i got the book back (obviously i didnt pay that, i am sane!), i fiddled with it by trying to start with just the battery. no response. with the battery and charger. starts for just seconds. and then with just the charger. walla! starts up and runs like new.

It happened when I was trying to install my right fan. The plug was too big for the connector and the connector just broke right off the logic board. I now see the solder points. They are too small for a normal soldering iron so I can't solder the wires directly on. What are my options now? I hope I won't have to replace the logic board considering it's working perfectly except for this one part.

After 1.5 years of use, my MBP's hard drive failed. So I purchased a new SSD and followed carefully the installation guide on [url].. and also [url]..
After the installation my macbook was unable to power up. I took it to Apple Genius Bar and the guy told me my Logic Board has been damaged, possibly because of the installation. He also told me I was not meant to disconnect the battery connector because this causes damage to Logic Boards.
Info:MacBookPro, Mac OS X (10.7.2)

I've got a 20" 2.1GHz iMac G5 iSight on my bench that doesn't power up.
I've tracked down the issue to a grenaded IC on the logic board.
The IC is an 8 pin SOIC chip, to the right of the power connector, just above the ALS connector. It is labeled UE300.
If you know what this guy is, can send me a good picture of one, or can provide me with the numbers from the IC, I can get this mac back to life.

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.

Over Christmas my MBP was put in an awkward position resulting in the USB thumb drive plugged in to the side USB port being bent. The damage was mainly to the thumb drive itself.
A few days later I tried using this same USB port for something else and noticed it appeared to be dead. I tried an SMC reset which didn't help, so I thought I'd take the cover off to inspect any possible damage. I wasn't able to see anything obvious apart from small, thin golden "buttons" with pointed heads that appear to be on a spring (I can't think of how else to describe them) that are in line with each of the USB/Firewire/Display ports on the left side of the logic board. Coincidentally, the button that lines up with the dead USB port is pushed in and not springing back out.
I have a genius bar appointment for Thursday, and I'm worried that I'll be told that I have to buy a new logic board to fix my little USB port. However, I was hoping someone could confirm my suspicions (and general curiosity) about the function of that little gold button I described above?

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've been using my pmg4 for a while, just recently I noticed that there is a red light located on the logic board on corner of processor heatsink and ram boards. this light is active during when the computer is on. the computer did not misbehave but is it trying to say something? is this normal operation?

Mac Pro, Mac OS X (10.7.2), MacBook Pro 13.3 | Logic Studio |

I have a dual 2.0GHz G5 that's refusing to boot consistently/run consistently. Here are the symptoms:- Runs for inconsistent period of time; sometimes it hangs just after logging in, other times it hangs after an hour or so of backing up the boot drive (50-75% complete)- Fails to boot after hanging; sometimes it stops at the gray Apple screen without a wait icon, sometimes it stops at the same screen with wait icon, other times the screen stays black- Frequently will not boot into single-user mode- Frequently will not allow you into open-firmware

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.

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.

How do I fix it? I assume the Repair program is expired, so how would I go about fixing it myself?

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?

I 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?

As 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 am looking for a motherboard and possibly processor for a MDD g4 powermac. I need the 167mhz version, rev with dual firewire 400 ports. Also, possibly a dual 1.25ghz processor module. I have either a dead processor or motherboard in this machine and I am having trouble finding some used replacement parts.

I've got a 900mhz G3 iBook that my wife uses. The logic board was replaced on it once already. It's really starting to act up again. I see Apple is still honoring their Logic Board switch out. What are the chances they'll upgrade it to a G4 or a macbook ? Has any recently sent there iBook in for a logic board replacement? How'd it go, how long did it take?

Can you put a 800Mhz g3 logic board in 700Mhz g3? I read somewhere that I will have grounding issues. Is that true? Has anyone done this? My ibook has been sitting here unused for the last 4 months and I would like to see if I could get it working. (The video chip has died and I have tried to get it back)

my G3 iBook's logic board has died (it was in that series that had the logic board problem). I had it replaced once already when it was under warrenty. However, the second one has died and Apple will not touch it (unless I pay something like $350 for Apple to fix it). Well, I decided to take matters into my own hands and I ripped open my iBook piece by piece. Now that I have the logic board in front of me, what can I do to fix it? Can I sodder something? Should I take it out and buy a new one off ebay?

My 17 inch iMac G5 1.8ghz seems to have died. For a while it's been refusing to power up and then powering up randomly but now it wont power up at all. I've looked on the logic board and reset the SMU etc but I can only get the first LED to light up. I think this means the logic board has died. Is it worth replacing the logic board and can it be done easily myself? Or should I just bite the bullet and pay out for a new alu intel iMac? I'm in the UK btw, any ideas on logic board prices?

I'm obviously new with Power Mac G5. I have two different logic boards for a Power Mac G5. The EEE code and part numbers are as follows:
Logic Board 1:
EEE Code: SML
Part Num: 661-3585
Other Num: 630T6907 (I don't know what this number signifies)
Logic Board 2:
EEE Code: SMJ
Part Num: 661-3584
Other Num: 630T6906 (Again, I don't know what this number is for)
My question is this; what configurations can I use these boards as replacements in? I'm looking at 3 PowerMacs right now but none have matching EEE codes. I listed the EEE codes and the type of machine they are below.
PowerMac 1:
EEE code: Q5M
Single 1.8GHz G5, 1GB Ram
Power Mac 2:
EEE code: ROR
Dual 2.5GHz G5, 1GB Ram
Power Mac 3:
EEE code: Q6E
Dual 2.0 GHz G5, 4GB Ram, Bought in late 2003
So, if it is impossible to use these logic boards as replacements in any of the above mentioned systems, which systems are they actually good for? I understand there may be system bus speed differences for one. But is there some sort of reference for these EEE codes such as a table or chart? Or possibly a compatibility list or description table with features for each board?
