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.

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...

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.

MacBook Pro Retina showing spinning ball issues even after Main Logic Board Replacement

HI there!
I'm a proud owner of Macbook Pro, 15 inch, late 2013 model. It has 2.6 GHz Intel Core i7 processor; 16 GB Ram, 1 TB PCIe based SSD. The software version is OS X 10.9.4. I have AppleCare.
1. MY mac developed rainbow beach ball issues. Sometimes it'll last for ages. I took several videos of them. I spent hours chatting with online Apple advisors. They did everything they could possibly do: Repair Disk, Repair Disk Permissions, SMC reset, PRAM reset. When nothing worked, I did clean-install the Mac six or seven times. Every time other apps would randomly cause the spinning ball issues. My Mac even restarted all on a sudden because of kernel panic. So at last, I took it to an Apple Store which is a one-mile drive from London. They diagnosed it as a graphics issues and replaced the Main Logic Board and put it to standard testing which revealed no other anomalies. After the repair, I noticed that dock icons remain present for a dew seconds when I restart or shut down the computer. So this time I took it to a London Apple Retail Store. The Genius at first diagnosed it as a display burn-in issues and sent it to be replaced with a new one. However, next day the technician who actually worked on the computer, phoned me saying that they could not reproduce any issues and did not replace the display either. I went to take my Mac back and discovered that the dock icons stuff still persist when restarting or shutting down the Mac. When I drew their attention, they told me that it was a software issue that Apple is aware of. Apple might resolve the issues in the future updates. Well, after getting back to my hotel room, I clean-installed my OS from USB and the dock icon issues were gone. Same version of software, but different behavior.
2. But that's not the reason I'm here. My Mac has again begun to show the rainbow beach ball one day after the repair, when I try to connect to my Airport Time Capsule through Finder in order to selectively transfer files to my Mac. This time the spinning ball would last for a very short time. But if I want, I can regularly reproduce them. I've also noticed this when installing MS Office for Mac 2011 edition. I'm sure I'll get the nasty ball as I use the Mac more and more.
3. I've got some questions: Can it be that during the MLB replacement, some other connectors got harmed? Or the issues are not specific to graphics only? Why didn't Apple find any anomalies during testing? I'll go to Apple Retail Store again, when I get the chance to. Once there, can I ask them for a full replacement of the Mac? Shall they take my request otherwise? I really don't feel comfortable using a shouldered computer which is going to go through many parts replacements.
4. I sincerely need your feedback. Please help me guys out there.

Applecare was no help at all. I called and did the complaint. They confirmed that it is registered to me and everything but essetially told me that they cant give me answers as to what is taking so long. They knew a repair was in progress but wanted to set me up with an appointment at an apple store? (the nearest Apple retail store is Billings which is 240 miles away, or about 4 hours). i tell them its at the repair place and they go on to tell me they can send me a box to mail it in and have it reapir by them.. They are trying to shift the blame to the AASP and his rep. But he said he has been trying with very few answers from Apple as well

Main logic board

Hey
I would like to ask if there is a warranty for this product. I have a Mac Book Pro 15" from march 2011 and the main logic board is broken.
Now is there a
class action law suit? Or does apple make exchanges? I don't want to buy a new board for 400 Euro in case
best wishes,
Nereton

Though his response was snippy - I tend to agree with Kappy's response.
He has 7000+ posts, his blue bar is nearly full, and always pulls through with great technical advice.
I understand that you have a legitimate question of an "easy fix", but we would all assume that if Apple repaired your product recently, and repaired a part that is now not working properly, that you would best be on the phone with them immediately to take care of their mess up.
Bottom line for you to understand is that Apple uses New, Used, and Refurbished parts in its repairs and some bad parts can slip through. Unfortunately it's nothing that we users can suggest in terms of software; you clearly have replaced hardware that is causing a problem.
Kappy - keep replying on... I give you a yellow star in my heart for that post!

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.

But since techs are not themselves given (allowed) too much information, my feeling is that some of them do things in a different way, depending on how they understand it.
AASPs and Specialists do not alter serial number information in any way whatsoever, including transfer or assignment of serial number to new components. They are not given the proper tools to do it, and thus aren't supposed to hop into NetInfo or a text editor and change language project strings.
The French serial number assigned erroneously to that fellow's board got there because it was a refurbished board whose original serial number had never been wiped or Apple themselves assigned the wrong number, not because an inattentive service tech did anything wrong.
Now, if some service tech DID decide to take it upon himself or herself to hack a serial number there, you still need to contact Apple, 'cause that isn't supposed to happen, and you still don't have a proper serial attached to the board.
Believe me on this one.

How to find and replace the main logic board on HP4600N Laser Printer.

Can anyone let me know how to replace the main logic board on my HP Laser 4600 N. My printer was freezing up and in calling customer service, they informed me that the main logic board is going bad. Now I have the part but no instructions on how to replace or where to find it on the printer.

A Google search may turn up a downloadable service manual for the Laserjet 4600.

New MBP logic board and wireless internet does not work anymore

hi there
i had to change the logic board in my only 2 years old MBP15". i purchased a new one and put it in by myself (relatively easy task). i still use the same internal HD as this one still works fine, so all data are the same.
however, the new logic board has obviously a different "identity" from my old one, it came with a sticker which says "ethernet ID 001FF3513E7A" which is different from before. this may be the reason i can still access my wireless network at home, but the self assigned IP address prevents me from connecting to the internet. all settings are as before and it worked always without a problem.
all settings were "automatic" before (using DHCP), and i use exactly the same settings again, but no success. i have to add that i use a new mac mini in the same network with absolutely identical settings (automatic) and this one receives a free IP address from the router (which is only in the last number different from the router's), but the MBP shows a totally different IP address.
i could finally fix it switching to "manual" and adding the same IP address the mini is using and just changed the last number, which has to be different from the time capsule i use as wireless device and the mini. like this everything works just fine.
but why does the mac mini perform everything automatic and the MBP (even with the new ethernet ID - and especially since i connect wireless and not using ethernet) is not able to do so?
i worry if i want to use the internet in any wifi hot spot i may run into troubles...
any idea what the difference between these two machines (with identical settings) is?
thanks and cheers
george

Thank you. It didn't work unfortunately :((
Here are my router's details (Huawei):
Product name HG655b
Device ID 00E0FC-21530307237S0B028701
Hardware version VER.C
Firmware version V100R001C02B018
Batch number RWC3P0.010.29066
Physical address 5C:4C:A9:A5:41:B0
System up time 0 days 0 hours 15 minutes 56 seconds
I don't have Mac filtering enabled.
Now it doesn't even find the wireless network anymore...
My computer and itouch are connected to WAP, but the iphone could not connect to WAP, but only WEP.
Any other ideas?
Thanks a lot!

Apple AASR asks 336€ for a new macminmi logic board, fare?

Hi
A friend has this mac mini which seemed to have ram problems, the light would blink on start up and then give in and shut down on its on during the whole start up process.
I re-seated the ram at one point for her and it worked., later we found it doing the same thing.
So i took it for her over to see a Apple Authorised Repair Center., now the guy says it will cost 336euroes ro replace the logic board., does this sound fare to anyone?
It is a first generation mac mini, it had the airport kit installed, 1 gig ramadn ran perfect for a year with a DVI adapter to a beautifull Apple 22" cinema display, the glass ones, not the tin man ones.
can anyone verify if the price for this is right, sounds a bit high and also unfair since you can get a mac mini for around the same price on eBay now.
here is goes for 100 Euroes less--> http://cgi.ebay.fr/Mac-Mini-1-25-ghz_W0QQitemZ270089360116QQihZ017QQcategoryZ140 199QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

In general a genuine Apple repair of a major item
like a logic board is not going to be perceived as
good value for an older computer.
Selling the computer for parts and replacing it with
new or used might be a better way to go. Or finding a
third party repair service.
I would imagine that the Apple repair charge involves
over a 100 Euros of labor cost.
any tips to who i can sell parts to?

Main Logic Board Replaced

Sent my MBP back for the 5th time for various reasons. This time they replaced the Logic board and it fixed my whine. I don't hear it at all. But they didn't fix my distorted speaker. Balancing from left and right while playing a low tone sound you can notice it still. I guess I will just try to ignore it and let it be. Anyone else sent their's and had the speaker issue fixed?

Hi, John. Yes, that's normal. I'm not sure why, but it is. Possibly it's so that if you call AppleCare for tech support or problem diagnosis over the phone, it will be obvious to the tech support rep that you no longer have your original LB. If you ever need it, you should still have your Powerbook's original serial number on your sales receipt or original box, and perhaps on the PB's original serial number label — though I've heard of Apple removing those too.
A Powerbook's serial number, as it comes from the factory, is identical with the serial number of its logic board. If the logic board is changed out, the PB's serial number doesn't agree with the serial number of the new LB. If either number still appeared in System Profiler, it could be misleading.

Getting New iBook Logic Board -- help? :)

Well I wasn't sure which forum to post this in, so I also put it in the 'Peripherals' forum.
Ok, here is my problem. I bought a G4 iBook 1.07ghz with a bad logic board from someone on craigslist. I am wanting to put a G4 1.33ghz logic board in it now. I found one on pbfixit.com for $550, but I also spoke with someone on ebay that said he thinks he has some 1.33's laying around. I am wanting a logic board with the two-finger-scrolling and the 'shock detection' features; also Bluetooth2.0edr and Airport Extreme. Well I asked the guy on eBay if he knew if his 1.33 boards had these features or not and he wasn't sure. Is there something he can check (model number/serial number/something physically on the board/etc) to see if he has any of the boards that's new enough to have these features? I'm not as worried about the Bluetooth+Airport Extreme because I found a module board on pbfixit with both of these in one.
Thanks!

Hi, abburke. Welcome to Apple Discussions.
(I have lots of Burke cousins, since my cousin in Wichita had six sons.)
If the iBook is circa 2001 like the iPod, chances are that's the reason the tech says you're out of luck. There's a three-year limit on the program.
Enough dual USB G3 iBooks suffered from this problem that Apple began the iBook Logic Board Repair Extension Program in January of 2004. Check out the FAQ page and if the symptoms look familiar, give Apple a call. If your iBook qualifies, it's a free fix.
If you are past the three-year time limit, try calling and asking for Customer Relations. Ask them to please make an exception to the three-year limit in your case. They have been making some exceptions to the three-year rule, but the criteria upon which they make an exception is not public knowledge. It could be how nice you are to them on the phone; it could be which tech you get; it could be which side of the bed the tech got out of on the morning that you call.
Good luck!

Application crash w/new FW800 logic board

Hi;
Two days ago I switched out the logic board in my FW400 SP 1.25 MDD dual boot tower with a used, but supposedly OK, FW800 board. Booted normally. Everything was OK for the first day. Also to note, on the first day I applied the iTunes and QuickTime updates.
Second day, I began experiencing application crashes - first w/iTunes, then Safari and iPhoto. iTunes wouldn't play more than a minute or so of a tune or MP3 file, then crashes. Safari only crashes occasionally, same for iPhoto.
Last night I opened the case while the computer was asleep. Saw a red LED glowing on the board - between the RAM slot and the video card. Never opened the case before with the O.E. board in so I don't know if the red light is normal. Did the usual repair of permissions.
Originally I left the battery in that came with the used FW800. Last night switched that out with the one from my FW400 board. Haven't experienced any Safari crashes since or tried iTunes & iPhoto but I just performed the battery switch.
Also, wondered if the system software needed to be updated to recognize the FW800 board.
My plan is to upgrade further w/the DP 1.25. Don't need dual boot function. Plan to install internal Bluetooth and Airport extreme card but haven't yet. Have both. Is the antenna kit for the Bluetooth module available?
Any suggestions you can give is appreciated!

May have answered part of my question. After installing the battery from my original FW400 board, no crashes. Ran iTunes, vids on Safari and scrolled through 1K pics in iPhoto, all at same time. CPU temp stayed at 105-106.

Logic Board Needed

Hi,
I have recently discovered that my 2 year old powerbook requires a new main logic board. The Apple part number is 661-3481. Does anyone have an idea where I can get one and how expensive it would be?
Thanks,
Abboud

Hi Abboud,
Welcome to Apple discussions.
You don't state which TiBook model you have, but depending on the speed, prices usually range between $300-600. Note: installation is not easy, so make sure you're willing to spend the money and time/effort before going this route. The money may be better spent on a used/working TiBook or a new MacBook.
