OS X :: Mac Startup Takes AGES After New Logic Board?
Jul 22, 2010
I have a small, well its not a problemm but anyway.
My macbook (late 2009) Is taking ages to start up. I just recently had my Logic Board fixed (headphone jack screwed up) and after picking it up from the shop it takes ages to start up... First there is a grey screen for about 30 sec. then the apple logo appears with the turning wheel thing for another 50 sec....
I do have over 40% harddisk space left... I only have BTT as a startup item and in /MacHD/Libary/startupitems i only have PACESupport....

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]

My iMac chimes when I press the start button but the screen doesn't come on. It's making a whirring noise so it's doing something. There's a DVD in it but it won't come out when i press the eject button on my keyboard. The iMac also doesn't show up on the network of my MacBook which it usually does. I was having a few problems earlier this week with the screen doing strange things - occasionally turning off, then coming back on. It was suggested that it might be a dying logic board but I tried a Apple Hardware Test this morning but it said no problems found. I have some files backed up but desperately need to get some recent documents off it [I know, I should have backed it up more often ]. Is there any way to get access to the files on the hard disc?

I have partitioned the harddrive on my Macbook Pro, one partition for OS X and one for Ubuntu, and then i use rEFIt to choose between the two. But some time in performing this process, the time between you turn on the mac, until the EFI(or now, rEFIt) is on, takes up til 15 seconds now. Before, it was about instant.
This is a huge problem for me, but I havent found any way to fix it.
Any ideas?

I've got safari 4 on 3 different mac's all running leopard with latest updates.
When browsing the web randomly it decides to take ages loading a page even sites like google. To make it load I have to stop it then press refresh.
I've tried unticking the fraudulent sites box and repairing permissions in disk utility, but i still get the same problem on all 3 mac's.

I have a REV A MBA running 10.5.8. Since i got the machine, it takes forever to show available software. After clicking "software update" from the apple menu it sometimes takes 6 minutes to check if there's anything new. Is this normal?

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?

I got a PowerMac 2.66 GHz Quad Core Intel Xenon with a 640GB HD. The system is 10.6.8. For some reason the Time Machine back up takes ages since a few weeks. I deleteted allready a few older ones and the free space on the back up disk is about 122GB. Today it copied about 700MB and it took over 30 minutes. I'm preatty sure this was a lot faster before. get it quicker again or what can be a reason that it is so slow.

I have a 2012 Macbook Pro running Lion (as you can probably guess!), with a 512Gb SSD and 8Gb Ram. Its a pretty fast machine and i'm really happy with the way it runs, however when I open a folder to view files, it opens and shows a blank folder and then I get the black pinwheel in the bottom left/right hand side and I have to wait for sometimes over 30 seconds before the files in that folder are shown!?
One thing to point out is that it doesn't always happen and its not restricted to particular folders. I can open a folder and it will show the files straight away, however I can re-open that folder and it will take up to 30 seconds to show the files...
I've tried rebooting and running nothing, but it still happens. And I have also tried the normal disk utilities to check permissions, etc and I think these are fine too..

Safari takes AGES to load pages and play videos!!! It takes 40 seconds to load the page the first time Safari is open (quit and open Safari or open after Mac reboot or cold boot) and 20 seconds to reload pages afterwards. Frustrating!!!
Firefox takes about 2 seconds, Chrome takes one second and Opera is real time. Latest versions of all in Mac OS X 10.6.8.

Installing the RC of Windows 7 on my Macbook and everything works perfectly fine however it takes ages to start up. The screen will stay at a black screen with a single blinking white cursor for around a minute when trying to start up the system. This is a windows download straight from MSDN so the windows operating system is clean and nothing fishy is going on.
Anyone else have this issue and/or found a way around it?

just purchased a new 27" Quad core i5 and it takes about 5 seconds for it to go to sleep, and then makes a loud noise after.
My hard drive is also noisy, it whines and drums constantly.
I also have got yellow tint on all sides of the screen.
I live in NZ so if i will not get a new replacement, instead it will be sent away to apple which will take forever
by the way it is the older 27" (late 2009) version.

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?

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?

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?

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?
