Wires running from logic board to frame of screen

Just a simple question. What do the black and gray wires running up the frame of the screen from the logic board do? Is there any relevance to its placement there, or can I re-solder them onto something else, And if i can, can i strip these wires to re-solder them?

No. But you might visit ifixit.com where you may find more information especially disassembly information.

Macbook Pro Video problems stemming from logic board

Recently my MacBook Pro 15" 2.4 GHZ started acting odd. Doing normal (i.e. nothing too CPU/Video card taxing) the monitor would work fine But it almost always happens immediately when playing a game, WoW for example. Then the display would show random odd characters and colors, almost as if the laptop went into a fit of rage. This almost never happens when surfing the web, using a text editor, etc.
I called Apple tech support and scheduled an appointment with a local reseller. The attendant there hooked up a device that quickly said something about a "4v video display adapter" not functioning correctly. She informed me that this meant the logic board was bad. I was quoted something about $310, but since I don't have that much to spend atm I didn't ask her for details.
My only real question at this point is how much does something like this cost to repair/replace? If it is the $310 (before shipping and handling of course) then I'm almost happy. If it turns out to be too much more then I will have to consider relegating my favorite laptop to minor duties and consider buying something else.
Thanks for any info/help with this.

Yesterday my laptop became emotionally distressed...my screen went berserk, diagonal lines everywhere. I rushed to the apple store and met with a genius, unfortunately he was unable to help me...I almost dished out $310 to send it in for service.
After multiple hardware and software diagnostics (Techtool Pro, ASD, Disk utility, Disk warrior, and Drive Genius) I could not find the problem. Then I came to the conclusion that maybe there are new default settings from new Snow Leopard update (10.6.3). MBP’s default fan speed...The GPU was overheating and creating a distorted video signal. How did figure it out you might ask, well I put the laptop in the freezer for 3 min and guess what, the screen went back to normal (Somewhat impatient). Then, I found little app that let's you adjust the fan speed RPM.
*smcFanControl 2.2.2* Control Intel Mac fans to make it run cooler.

Also, I will recommend a widget called iStat Pro and it also has a matching iPhone app to monitor your laptop temperature and other important info from afar.

I am somewhat concerned though, did overheating the GPU cause lasting damage to my logic board?Time will tell. Also, is this a issue that Apple should look into....Yes.

Unplugged battery from logic board now it won't recognise there's a battery plugged in

So over the last week I've been having issues with my power cable, often it wouldn't work, sometimes it would but it wouldn't hold for long. After a week or so it started flashing green but sort of more dull green. No orange. After some extensive research I found a temporary fix was to unplug the battery from the board plug it back in and voila. Supposedly. So when that didn't work, and after spotting the tiny teeth marks right beneath the MagSafe bit from a very naughty kitten, I bit the bullet and paid the £60 (expensive when you're a jobless student, hey, times are tough) for a replacement charger, and the new cable worked a charm. BUT, now my MacBook says it's got no battery available and I'm thinking maybe I've been a bit of an idiot unplugging it. I'm on an early 2011 MBP running a version of snow leopard. I've done all the smc resets etc and the stuff for kernals? (I'm not mac proficient yet) and now I'm thinking maybe I need a new battery but I can't afford one or the diagnostic + replacement charges at the Genius Bar. So I pose this dilemma to you, the community, in the hopes that someone can help me. I can provide any extra info necessary so don't hesitate to ask. Many thanks for responses.
A confused, lost and terrified man.

Try the SMC again. Make certain that you use the correct instructions.
http://support.apple.com/kb/ht3964
If no success, make an appointment at an Apple store genius bar. The diagnosis will be FREE. Any repairs will not be free but you will know exactly what you are dealing with.
Since you MBP does not even recognize the battery suggests that there is a connection break. I'm wondering if damage was done when you disconnected and then reconnected the battery (to the battery connection).
Ciao.

Does this sound like a logic board problem? Blue screen

I have a G4 1.33GHz iBook 14". Recently it has started having problems with freezing and booting. It will boot normally, but a few seconds or minutes into use, if freezes, and only a force shutdown with the power button will work. Then, when it restarts, it may run fine, or may freeze up. Sometimes when it boots, the apple logo shows up, then the spinning wheel, then a light blue screen. And then, nothing.
I have tried all the usual stuff, including starting with the 10.4 DVD and running disk utility. Also Onyx and version 3.03 of Disk Warrior. It wouldn't boot from the Disk Warrior CD usually, and the one time it did, if froze up.
SO, I ended up booting it in Firewire Target Disk mode, and reformatting (zero'd out) using my MacBook. Then, reinstalled the 10.4 and upgraded to 10.4.7 using Software Update. It worked fine for about two hours, and then started freezing and blue screening again.
Does this sound like a logic board thing? It just occurred to me that I haven't tried all this stuff with my additional 1 Gb stick of RAM out. It hasn't caused any problems before, but I suppose it might affect this, no?
Sorry for the long post, but I want to try to diagnose and fix BEFORE it goes off to Apple to be returned with a "we can't demonstrate the problem" message and a bill.
Thanks
Roger

I took out the 1 Gb stick and it did the same thing. About half the time it boots, works for a little while then freezes up. The rest of the time it won't boot past the spinning wheel then the blue screen. Same deal with the OSX DVD and the DiskWarrior CD.
Frustrating. I may have to send it in.

Trying to run from logical partition - GRUB doesn't detect it

Hi all, I only have a single SSD in my laptop with the following setup (in order on disk):
sda1 - System Reserved
sda2 - Windows 8
sda4 - Extended Partition
sda5 - Arch 2 (this is where I'm trying to move my Arch install to)
sda3 - Arch (this is the one I can actually boot into
(unallocated space)
This is what I want things to look like eventually:
sda1 - System Reserved
sda2 - Windows 8
sda3 - Extended Partition
sda4 - Arch
sda5 - some other distro
sda6 - storage (I want this accessible by all OSes)
Here's how I think I'm going to do this:
- move Arch installation from after the extended partition to before it (since the extended partition is a big chunk of mostly free space, and I would like it to go last.
- after verifying that I can boot the Arch installation from the logical partition, delete the Arch installation on the primary partition and absorb the free space into the extended partition
Here's what I've done:
- used 'dd if=/dev/sda3 of=/dev/sda5 bs=4096 conv=notrunc,noerror' to clone my working Arch installation to the logical partition (sda5).
- ran 'grub-mkconfig -o /boot/grub/grub.cfg' to update GRUB and add the logical partition to the list of things to choose from in the Grub menu.
After running 'grub-mkconfig' nothing new was added to the menu.
Questions:
- Is what I want to do even possible?
- can I have the logical partition marked for storage be accessible to Windows 8?
- Is there an easier way to do what I want to do?
- How do I get GRUB to detect the logical partition?
- Is it possible to boot into a logical partition?

grub doesn't always automatically pick up arch installations. Is os-prober installed? You can always add the entry manually e.g. in 40_custom or whatever. Don't forget to adjust fstab.
Just to be clear: you have an MBR formatted disk and are talking about traditional logical partitions, right? Not lvm?

Exclude one field from Logical Database's dynamic selection screen

Hi Guru,
I have a requirement to amend a program to exclude the document number field (bsik-belnr) from the dynamic selection-screen of the logical database KDF(Vendor Database) so that the program will not filter according to the document number.
I have use the below syntax in my zprogram.
selection-screen exclude select-options: doc-no.
However I get syntax error "The addition EXCLUDE is only allowed in INCLUDE DBKDFSEL".
Please advice.
Best Regards,
Fung

The selection part of the logical database defines input fields for selecting data.
          The runtime environment displays these on the selection screen when you run an executable program linked to the logical database.
          Include called DB<ldbname>SEL.
        SELECTION-SCREEN BEGIN OF VERSION ver TEXT-xxx.
                                                                SELECTION-SCREEN EXCLUDE ... .
                                                SELECTION-SCREEN END OF VERSION ver.
Defines a selection screen version (with a three-character name ver ). Between BEGIN OF VERSION and END OF VERSION , you can exclude selection screen objects for the version ver , i.e. remove them from the selection screen with SELECTION-SCREEN EXCLUDE.
          SELECTION-SCREEN DYNAMIC SELECTIONS FOR TABLE dbtab
If one of these tables is active in the report (i.e. it is declared under TABLES or lies somewhere on the path from the root of the database hierarchy to a table declared with TABLES ), a pushbutton called 'Dynamic selections' appears on the selection screen.

Hi there, i have question regarding my dads ipad mini. theres a crack running from one corner down across the screen cause of my little brother. im not sure if apple will repair this for me? Im still within the one year warranty if that helps

I Have a ipad mini i bought my dad as a gift and he let my little brother play on it frequently (9 years old) and one day he dropped it in its case, it seemed fine till a hairline crack in the corner began to swim across the screen. It's still within the one year warranty i checked online but im not sure what apple will do for me or can do for me? Can it be replaced?

It will cost you approximately US$219.00.
Apple will replace the entire iPad; they don't repair.

Multiple Logic Board Failures... Advice?

My black MacBook is less than two years old. Starting this past January, I have had a total of three logic boards fail, along with other hardware failures, including the SuperDrive and Keyboard/Trackpad Module.
Every time the board fails, it is because of a different problem than the last time. First, a connection wire was faulty, causing the Super Drive to be replaced as well. The second time I don't know what was wrong with it, but it was replaced along with the Keyboard/Trackpad Module. This last time, the Speaker/Headphone connections were stuck, which again, caused the Geniuses to replace the Logic Board. The LCD screen was also replaced, but because of dead pixels. Also the hard drive quit working (thank god for backups). I am now on my 4th Logic Board in less than 6 months.
My computer is still covered by AppleCare for another year and a half, but the repeated servicing and re-registering programs is getting a bit ridiculous. Not to mention, if this keeps happening after the warranty runs out, it will be very expensive. I have no money to buy a new computer. The only reason I have this one is because I got it for my 18th birthday from my family.
Is there anything that I and/or Apple can do in this case?

Many things can cause a logic board to fail, from environmental problems to a run of defective parts used in the manufacture of a particular batch of boards. What you can do to help prevent problems are:
1) avoid giving your system (or any electronic device or component) any sort of static shock. Static electricity can easily damage solid-state devices. If in the area in which you have your computer you're regularly getting shocks when you touch metal or grounded devices, you need to take steps to reduce the static electricity buildup.
2) make sure you're properly grounded whenever you access the internals of the system, such as to remove or install RAM or hard drives, and install only quality components verified as compatible with your computer.
3) use high-quality power protection devices on the AC power to your computer and any connected devices (printers, scanners, networked devices, etc.) The $10 "hardware store special" surge protectors generally do more harm than good; get high-quality surge protectors or, better, a power conditioner or uninterruptible power supply with good power filtering.
Beyond that, it's rather the luck of the draw. But MacBooks in general have as good a track record of reliability as any laptop and better than many.
Regards.

What logic board do I need

Hi there, I got my brothers old macbook and was thinking of fixing it. I know its the logic board because we had it tested when it failed for him in the past and for some reason I've resurectted the idea of getting it going again. Its a A1226. Now, I've been looking for logic boards for prices just to get a ball park and Im willing to risk it. However, I want to make sure I get the correct logic board. I need to somehow fire this thing up so I know exactly which processer it was. I'd run the serial # but the under belly is so scratched that I cant read it unless I find a magnifying glass. Any how, any advice on how to find out the correct logic board for this laptop. Would I have to open it up? THanks for any help.

Since your specs at the bottom say 1.5GHz, you need the logic board that goes with the 1.5GHz 12-inch PowerBook G4. You can buy these on eBay or from resellers that have them in stock.
Logic boards along with LCD screens are the most expensive parts, of course, since they are the most crucial to its operation.
Don't buy a 1.33Ghz, a 1.0GHz, or an 867MHz logic board.
Apple has a flat-rate repair, but it is not necessarily cheaper. Depending on the condition of your PowerBook, inside and outside, the flat-rate may be bumped up based on "tiers." The flat-rate costs about $300 for "everything" (parts and labor) if all checks out and is approved by the Genius Bar and the subsequent techs at the Service Center.
If there is an issue, it might cost more. Those, I don't have information on. (Price-wise).
If you're gung-ho and want to replace it yourself, you have that option. Or, choose your own service center to do it for you. (TechRestore.com, MacService.com, etc.-- even a local "mom and pop" shop in your city).

Logic board replaced, now network settings won't save

Got the black screen, Apple replaced the logic board on my MBP for free (yay, Apple!), but now it won't remember my network settings. I have to run network diagnostics, type in my pswd, etc., every time I wake from sleep.
When I first got it back from Apple, it couldn't find the network at all, and Apple gave me free tech support (again, yay, Apple!) because I successfully argued that the logic board replacement had caused the problem. I didn't realize in that support session that setting up a new network, while it would be saved in the system, would not automatically stay "on" -- otherwise I would've dealt with that then.
Running: 10.5.8 on 2.2 ghz late 2007 MBP. Cable modem and Airport Extreme. Others in house have no problems with wireless connection. The only thing that's changed is my logic board.
I read through several discussions, which talked about editing system files and such that I'm extremely uncomfortable doing, and there doesn't seem to be a definite solution for this problem stemming from logic board replacement.
Thanks for any help...

Hi Kren,
It sounds like just a setting: Open System Preferences > Network > click on Advanced > click on Remember networks this computer has joined > you may wish to uncheck all the boxes for Require administrator password > click OK (I don't remember if you have to click Apply on the next screen, but if it's highlighted, you need to; if not, close Network and you should be good to go).

I got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) and now my microphone is not working

I got my Macbook Pro 17inch (early 2011) back from Apple (they had to replace the logic board) 3 days ago, I had a terrible experience as the genious who gave me my solid state disk for safekeeping lost my disk's brackets thus I had to wait 2 more hours until they find one after 10 days of waiting for the repair. I noticed some weird sounds, like somehting is moving with the mac 1-2 times, even if I have no mechanical parts other than the fans, but my real issue at the moment is that my microphone is not working. I can see the mic in the System Info however and in Audio Midi Setup. In the Audio Midi Setup I see that the master chanel is turned off and I can't turn in on. Ch 1 and 2 are on full. I also noticed the first seconds after the comp. boots the blue bar goes to the middle in the System Preferences -> Sound -> Input. Any ideas what to do or try? I do not want to go back to the apple store as it is 50 minutes away from here and I need my laptop as a computer science student. Everything else is working perfectly.

You need to call both the store that did the repair and Apple directly, warranty service or Apple care, and report this problem with both of them and get a ticket number of some kind (some kind of verification number) that the unit just came back from major service with this problem and that you want it fixed when you can lose the use of it, which is not right now.
Without doing something like that they could easily say it is damage not covered under the normal warranty.
God knows what the repair center did and did not do to it while it was there.
And depending on when you actually bought it the warranty could run out in the mean time.

Upgrading from 10.2 to 10.3 w/ history of logic board failure

Please forgive if this has already been asked but...
I have an IBook G3 that has had 2 logic board failures in the last 2 years. Is it worth upgrading to 10.3 (Panther) w/ my history? I cannot upgrade most applications ( Itunes, Safari, AOL...) b/c I'm not running 10.3. I don't have the money to upgrade but need access to these things.
thankx

You can just install 10.5, assuming the machine supports it. It needs to be fast (> 1Ghz) and have at least 2 GB RAM. Otherwise, you'll be spending a lot more time at your mother's.
Don't attempt an "upgrade" of 10.2. Back up the data, then reformat the drive, then install Leopard. Don't run any migration utility. Set everything up fresh. Reinstall updated versions of all software that will run on Leopard. The only thing you want to copy from the old machine are documents.

Would I be able to boot from USB on my Macbook Pro if my logic board was damaged?

My macbook pro recently started to slow down, programs freeze, etc. Odd behavior. So I decided to install a clean version of os. My hard drive came up as corrupt, I need to repair. So I did that. And was unable to install to os. It starts up and then says that the installation has failed, but yet I'm able to install it on an external hd and boot from that installation. Is it my hard drive? Or is something wrong my logic board?

If you can successfully boot and run OSX from the external harddisk but not from the internal harddisk, then it is most likely that your internal harddisk is defect and not the logic board.
Nonetheless you should run the Apple Hardware Test Intel-based Macs: Using Apple Hardware Test to check your Mac.
It might be that the internal SATA-harddisk connection is defect.

Is it possible to run my computer if the logic board is dead?

Some water spilled in my computer a week ago and it stopped running. I sent it to repair to an authorized dealer and they said the Top Case and the Logic Board where broken. Anyhow, they gave me an expensive budget and I didn't fix my MacBook Pro.
I have bootcamp installed. When I came home I turned it as Mac and it turns out the screen is working but it got stuck at the grey apple icon with the loading wheel. I turned it off and booted as Windows. Everything went fine with Windows. I'm actually writing this from windows. Sound is working, keyboard is working, screen is working. It seems fine.
Is it possible that they gave a wrong diagnosis? How can I fix my Mac partition without format?
Cheers

Get files from old MBP to new MBP when the old one has suffered a Logic Board failure

Recently, my 2009 unibody MacBook Pro died. Logic board failure, I am told. It is out of warranty, and replacing the Logic Board would cost a grand. It had some other issues too, so I figured upgrading to a brand new system would be the best idea. So, I am going to purchase a brand new one within the next few days. My question is this: How to I get the files from my old MBP (I NEED them, plain and simple) to the new one once I get it? Should I take out the harddrive from the old one and connect it via a SATA>USB cable and connect it to the new one? Can anyone shed any light on this? It will be much appreciated. Thanks.

Yep, all you need is a IDE/SATA to USB adapter for about $20 online at OtherWorld Computing, NewEgg and other online computer sites like Amazon etc.
You can find the screwdriver or other torx driver at iFixit or OtherWorld, just look for your Mac model or just be rough with it and drill out the screws.
You can choose to get a enclosue and use the drive as a external drive, it will cost more naturally, but for a few bucks more though you can get a brand new external drive and likely twice the capacity.
Some external drives can't be Carbon Copy Cloner and option booted from, so perhaps a adapter is best. (don't clone a OS from another Mac to your new Mac)
Setup:
When you set up the new Lion Mac, name the hard drive the same name as the external drive, also setup the same user name as the old Mac had. Software Update.
Install all your known third party programs from fresh sources as many as possible.
The last thing you do is connect the old Mac drive, transfer all the files from the user folders right back into their respective folders on the new drive (Music, Pictures, Documents etc) Not User/Library.
Open all your programs like iTunes and iPhoto and it will update for your files, then go through the folders and delete what you don't want.
Don't use migration or setup assitant, it's a blind copy, includes programs you can't use anymore and other headaches.
If you do things in the order I specify, your drive will be optimized and run fast for a decent amount of time.
If Lion act's glitchy, Carbon Copy Cloner to a new HFS+ Journaled (Disk Utility) and then hold Command R to get into Lion Recovery, Zero Erase the OS X Lion partition and then option boot from the Lion clone and reverse clone onto the OS X Lion partition on the internal.
You can also reinstall Lion on top of the factory Lion from the Recovery Partition.
search "apple support Lion Recovery" for details.
