Time machine and bad logic board

I have an iMac G5 with 10.5.8 that I think the logic board is going for the second time. I can boot up in Safe Boot. Can I simply turn off Time Machine and the External HD until I get the iMac G5 diagnosed or replaced. If I get a new iMac, I'll want to use Time Machine to Restore the:

TM makes a full copy of your hard drive. you can restore anything and everything you need from it. you can do a full system restore which will give you the exact copy of your current system or use Migration Assistant which will only copy the things you mentioned.
P.S. TM does work in safe mode.

Is a bad logic board due to a bad power supply?

Computer specs:
iMac G5 20", 2.0 ghz, 1 GB RAM, 250 GB hard drive
Back in October of 2008 my iMac G5 Power PC shutdown intermittently and then when I went to go to start it back up, it booted to the blue screen and hanged there forever. So, I did a hard shutdown and then waited and then booted again and it still hanged at the blue screen. I tried booting in Safe Mode, and that worked, so I had a chance to backup everything that I needed to. Then, I took the computer to my local Apple Store to speak to a "genius". They could not diagnose my computer while I was there, so they needed to take it overnight and let me know over the phone what the issue was. The next day they called to tell me that it was a Logic Board issue and that it would cost $900 to fix it. I obviously was blown away at the cost for the problem, and I could not afford that charge so I seeked out other options. I found a shop in my neighborhood that offered me a used 1.8 ghz logic board for half of what Apple was quoting me, so I went with it. Then, 9 months later (which brings us to present) my iMac completely shutdown on its own and would not start up. I ran it through some tests (LED lights on the interior) and confirmed that it was a Logic Board issue again. So, I took it back to the shop in my neighborhood and they told me that the warranty for the part they replaced had expired. So, I called Apple Customer Relations to talk to them about the issue. They confirmed, using my serial number, that I could get my issues fixed for free. They then told me about the "iMac G5 Repair Extension Program for Power Supply Issues" which was news to me. This Program ended in December of 08, meaning I would have qualified in October of 08... the time I initially brought in my computer. So, I brought my computer to the Apple Store to drop it off for repairs, and when going over the history of the machine they confirmed that because there was a used 1.8 ghz part in my machine installed from a non-authorized Apple place that they COULD NOT fix my issues now.
My question is:
Back in October of 2008 when I brought in my computer to the Apple Store and they diagnosed it with a bad Logic Board, could that have been because of a bad power supply? If that was the case, does a bad power supply cause a Logic Board to go bad?

Welcome to Apple Discussions.
The short answer is no, but it's actually more complicated than that. The original iMac G5 17 and 20 inch models were plagued by two problems: defective capacitors which affected the logic board, and an unrelated set of defective capacitors which affected the power supply. Rarely were both conditions present at the same time, but Apple decided—when they issued the repair extension authorization—that replacement of both components was a more cost effective approach. By far, the most common of the two problems involved the logic boards.
The REA covered machines for a period of three years from first sale, and ended in December of last year. Yours likely would not have been covered due to the date of sale provision. On a case by case basis, AppleCare representatives did allow coverage for machines beyond the three year limitation, but not past the end of last year.
It's not likely that you have both a defective logic board and power supply, though you may. The combination of these issues is actually found most frequently in the iMac G5 ALS models, none of which were covered by a repair extension authorization.
Your issue is a difficult one, as Apple authorized dealers and service providers have every right—and, actually, a responsibility under their annual agreements—to reject warranty, AppleCare or REA coverage for parts or labor when compatible but not similar logic boards have been placed in your machine. This is because they must exchange these parts for the part they are requesting from Apple on a like-for-like basis, and that part must be associated with your machine serial number. In trying to resolve your issue, the shop in your neighborhood actually created an additional issue for you which would only be triggered in the event of component failure. I have no idea what period of coverage they typically offer, but Apple provides for 90 days or the balance of any warranty or AppleCare extension in place at the time of the repair, whichever is greater.
Your logic board can be refurbished for $ 189.00 if it in fact exhibits the capacitor issue. That process is covered by a one-year warranty. If you are interested in exploring that option, send a message to the electronic mail address in my Public Profile and I will reply with additional information. To help determine additional information concerning your machine, please include the machine serial number if you elect to do write for more information.

2007 15 inch MacBook Pro With Bad Battery, Bad Logic Board, Unreliable USB Ports - Good News Story?

I'm posting this to put it out there just in case someone else has had similar experiences. My MBP is a 2007 with the Intel Core 2 Duo 2.15 GHz processor running 10.6.8. I've had it since 2009, and it has been a flawless machine for me until recently.
In the last two weeks, the mouse would no longer respond to touch - it felt mushy instead of clicking. The machine also was extremely sensitive to any touch on the top of the computer. Lastly, and most frustratingly, the USB ports would randomly stop working upon waking the computer up. I use it in clamshell mode a lot, with a mac keyboard and a kensington turbo mouse. Often, the mouse would not work upon waking the computer up. Rebooting was the only solution and I was doing a lot of rebooting. This is my everything computer - work and personal - so I wanted someone to look at it.
I took it into a local business that specializes in Mac repair since it was vintage. After a day, the tech called me and said that the battery was split and that my other issues were probably logic board problems, and the logic board would be hard to find and expensive to replace. He said I might be able to use it without the battery, but that obviously would be a pain. The tech felt such pity for me that he did not even charge me the diagnostic fee.
I tried using it without the battery and the machine was extremely jittery in its response, plus the mouse button would still not work. I put the bad, split battery back in, and it did respond better (though not the mouse). I have just enough knowledge to know that electronics can behave very strangely when their batteries are bad and this one was especially bad. Against the tech's advice, I spent $69 for an Anker replacement battery from Amazon. I put it in, and all of my problems have gone away - including the mouse which now clicks just like it did 5 years ago when I bought it. It might be total coincidence, and I'm certainly not saying to anyone that if you have similar issues with your older, but much beloved MBP, that this will do the trick, but I did want to get this out there because $69 for a new battery is a lot better than >$1200 for a new machine (if you do not currently have or want to spend the money).
I do a weekly time machine backup and I will be really sad when this computer finally gives up the ghost, but since I've gotten a lot of good information from these forums, I wanted to pass this information along in the hope that it might help someone in the community. The two Steves have my undying admiration and respect.

Power Mac G5 DP1.8GHz - Bad Logic Board or Power Management Issue?

I have a Power Mac G5 DP1.8GHz/1.5GB/80GB which I bought non-working. It has not yet been disassembled or examined by a certified tech. This is it's issue (which replicates): the computer powers on. It makes a single warning tone, then the LED flashed at least 15 times (too fast to count). Then the posting chord is heard. Hard drive spins up. Then nothing (no video). Won’t boot from any disk. I have changed the RAM and tested the RAM banks with known-to-be-good RAM from another DP1.8GHz G5. The warning tone stopped once or twice after this switch, but then it didn’t chime. I changed the PRAM battery, but not with as new one. However, after installing the used one and then resetting the PMU, it displayed video briefly for the first time. While installed in the other 1.8GHz G5, the hard drive was formatted, given a clean install of OS X 10.4.11, and then moved into this computer where is never mounts. The computer is not accessible through TDM.
Do I have a bad logic board? Bad CPUs? A power managment issue? A RAM issue?

Through my own trial and error troubleshooting, I have found the CPUs to be in good working order and the logic board passes the Apple Service Diagnostic every time. Despite the installation of numerous pairs of modules that worked in another DP1.8GHz, the computer has a RAM issue-it gives the "no good RAM" tone most of the time when it powers up (after a PMU reset it does not). Also the computer boots from disk or into Open Firmware but the disk utility can't see either hard drive so I may have a bad SATA controller.

Will apple replace a faulty or bad logic board on my 2013 MacBook Pro?

I have a late 2013 13" macbook pro that has been diagnosed, by a non apple provider, with a bad logic board. The place where i took it suggested getting that confirmed with Apple. I have an appointment tomorrow at my local apple dealer...
but am worried that this practically new laptop is toast or going to be very costly since I don't have applecare!! Any help for me????

my late 2013 13" pro also has a bad logic board. The diag said it was a memory failure. I'm 3 months out of warranty and had it sent to the repair center for $280 plus tax. I don't feel like the logic board was defective I just didn't catch it in time. I tried a restore a few months ago and it worked better because i was in Yosemite beta since the developers beta and I thought the issues were because of the betas. It has constant panics and restarts but I was trying to get by until now it wouldn't turn on and disk utility said the hard drive was not mounted and it wouldn't let me restore It. maybe there are a few more people with problems then there should be so soon.

Powerbook G4 titanium bad logic board

HELP, my second computer is a powerbook G4 15" and i have been told i have a bad logic board. is it worth replacing or should i put the $500 toward a new one? Also coould a bad logic board cause other problems in the future? what happens to make a bad logic board? what does a logic board do?
thanks for all the info.
Macbook Pro Mac OS X (10.4.9)

Hi Tour Man,
Welcome to Apple Discussions.
Which model TiBook do you have? Especially if it's one of the earlier models (400-667VGA), I would certainly not spend $500 on it, as you would probably not be able to sell the entire machine for that price.
If it's a later model (667DVI-1GHz), consider what you use it for (if you have it fixed, how long is it going to serve your needs?), the capacity of the HD, how much RAM you have, whether there's a wireless card or DVD burner, the condition of the battery, whether USB2 and the many other "updates" a new machine would offer are important to you, etc.
It's not likely that a bad LB would cause other issues.
A LB (same as "motherboard" in PC land), is a circuit board on which most of the essential elements of a PB are soldered (CPU, GPU, RAM slots, etc), so when any one of these has issues, the repair is to replace the entire LB (specialized equipment is needed to work on the micro-circuitry, so it isn't something a repair shop can repair).

Display problems, bad logic board?

Hi I'm a first timer here! I have a iBook G4 14" 1.33ghz laptop I am fixing for someone. When it boots up, the screen looks like you are watching TV with old rabbit ears. You can make out the mac logo and what not, then the screen goes blue, like the basic blue background, and it looks perfect, then once the desktop comes up, it all fuzzy again. I've replaced the LCD screen, AND the lcd cable that connects to the logic board. Same results. I guess the last part would be the logic board to replace? Does anyone have any suggestions?
Here are some links to the pictures to show you what is going on...
http://www.tylersweb.net/mac/1.jpg

http://www.tylersweb.net/mac/3.jpg

inverter board controls brightness, the lines in your pics look more like the logic
since you have a stick of RAM, try another module or maybe remove it if you have on-board RAM
would be good to connect to the external display if the adapter is available - it would confirm bad logic board if the same lines are on the external display, it wont completely rule out the board though if there are no lines

Difference Time Machine and Back-up

What is the difference between Time Machine and Back-up to .mac or?

Time Machine.. backup software on your Mac computer. (Only 10.5 and after seeing you list 10.4)
Time Capsule.. hardware device which is an Apple Airport Extreme plus a hard disk wrapped into a bit bigger box than the AEBS. Dumb as a board.. it is a router with hard disk hanging off. Entirely unsuitable as external storaage as it has no backup method for itself. It is a target for Time Machine, so Mac Laptops can back up wirelessly.

I want to store pictures on an external hard drive. They told me in the Apple store I could do this on time machine.
I am not sure if the Apple Store folk told you the wrong thing misunderstanding you.. but you cannot use Time Machine as a store. It is backup and files inside it are not usable.
Moving your iPhoto library to the TC is also a really bad idea. If you simply want to store raw photos.. which is a good idea btw.. as iPhoto kind of consumes them, yes, you can put them on the TC.. but use another location, external drive to back them up. In fact do it the other way around.. use the external drive to store them and stick to TC to work as backup since that is what it is designed for.

How can you transfer files from an iMac with a bad logic board?

This is in reference to my "Nothing but a blue screen at startup!" post. He took his iMac to an Apple authorized repair shop and he was told that the logic board was shot. He has decided to get a new iMac but he's wondering about all the photos and other files he has on the old hard drive. What are the ways that he can get files from the old hard drive on to his new one when he gets it? Thanks in advance for your help with this!
Eric

Hi Eric!
roam's method is a very good one!
I don't know if this will work because of the bad Logic Board, but another way, may be to use Firewire Target Disk Mode.
The ailing iMac would have to be Firewire enabled, and you would need access to another Firewire Mac.
Good Luck!

Can't boot G5, bad logic board?

G5 Dual 2.0 Ghz, 4 GB Ram
Can't get past blue screen unless I boot in safe mode, then I can get in.
Here's what I've tried:
5 different boot volumes, including Tiger and Leopard and a clean install
internal drives only, external drives only
reseated ram
zapped pram
zapped nvram
reset pmu
booted in single user mode, gets stuck at workaround bonjour unknown error 0
pulled out airport card, reseated airport card
tried just about everything, always stops at the blue screen with cursor
does this sound like a bad logic board or is there anything else I can try? thanks

Dear Mr. Jarrett,
Just analyzing: You're not able to boot normally from any installed system on any hard disk, but you can boot in the single user mode, are able to use AHT and the G5 even boots from the TechTool disk.
However, you do not state you installed those five systems mentioned recently, so the question is: How stable is your computer booted from a DVD (grey install disk or the TechTool bootable disk and are you able to do a fresh system install now?
I don't think your RAM chips are bad, but there could be a problem with (one of) the SATA cables connecting the hard drive to the logic board. Did you try both data cables (by using the second drive bay)? As you undoubtedly know a PowerMac cannot boot from an external USB drive, but having a bad internal data cable could also prevent starting up from a FireWire drive. And take a critical look at the four guide screws: are they well fitted?
From your description I understand you own a dual processor and not the late 2005 duo core G5. These computers are very different animals indeed.
Success and best regards,
Robbert

WD External HD not backing up thru Time Machine and can't access files

Hello,
This is the snapshot picture of my problem:
http://i668.photobucket.com/albums/vv43/no-real/computer/Picture1.png
When I connect the WD 500GB drive to my Macbook Pro, the computer doesn't recognize it in the devices list (The WD-HD seems running when I connect though USB or Firewire), nor the Time Machine can find it.
I'm hoping someone can help me after exhausting all resources I checked on the net.
This problem suddenly started about two months ago, whereas before there was no problem for about two years.
I read forums and one said to start Disk Utility and have it recognize the HD. The first time it didn't recognize it, but starting and quitting Disk Utility few times the HD was finally recognized. However, the Verify disk or Repair disk can't be completed (Error sign) The snapshot of my situation is like this:
http://i668.photobucket.com/albums/vv43/no-real/computer/Picture1.png
Another forum said if the HD was formatted for Windows (Which I used for the first few months using this WD-HD) and wasn't formatted for Mac, which I can't remember if I did, this could be causing problems?
I'm very careful about ejecting or shutting down my External HD properly, and I can't remember a time when I disconnected it improperly (Who knows, maybe I have)
Any thoughts and/or solution for this problem? Or am I doomed to reformat the whole drive.
The iomega Drive you see in the snapshot is a new one I bought and works just fine.
Thanks

So I tried everything but to no avail.... I will reformat the disk. Luckily I had most of my critical files on the Mac HD so... the damage is not all that bad!
Thanks for all the help here... and when I went to the apple store today and consulted, they said it is a better idea to store on two separate disks, one with time machine, and one with the old fashion drag and drop to diversify risk.
I'd disagree with the second part of that -- drag and drop is not a good backup solution. I've learned over the years (mostly the hard way, of course ), never to trust my backups to a single app or piece of hardware: no app is perfect, and all hardware fails, sooner or later.
Like many here, I keep both full Time Machine backups, plus a "bootable clone" on a separate external HD. I use CarbonCopyCloner, many use the similar SuperDuper. That gives me the best of both types of backups, plus of course a completely separate, independent backup.
CCC is donationware; SD has a free version, but you need the paid one (about $30) to do updates instead of full replacements, or scheduling. Either is easily found via Google.
And/or, see Kappy's post on Basic Backup, complete with links to the web sites of each product.
And by chance, before I will reformat, is there a way to access this External disk with some files? It shows up on disk utility.... maybe a way to just manually pull out some files?
Since it doesn't appear in the Finder, no.

Seems that you have to update Logic to the latest version (9.0.15) to get it to work in Lion.

Time Machine and External Hard Drive

I have a 1T external hard drive and Time Machine has backed up my entire Powerbook G4 laptop on it. I would like to free up space on my laptop by deleting some things that I want to save on the external drive, but don't need on the laptop, how can I do this? Every time I try to delete something from the laptop, it simultaneously disappears from the external drive. Please help!
Also, I keep reading about partitioning - what is this and how do I do it?

Hi
I think the point to address is that an intrinsic part of "backing up" is that you always have two copies of something. One original, and one if you lose the original, either if you accidentally delete it, or the hard drive crashes, etc. What you want to do is backup a file through Time Machine, and then delete the original - which is NOT a sensible backup procedure (because now you still have only one copy of your file).
That aside, Time Machine is designed to be a continuous backup of your system at any point in time. So if, last week, you had a certain file A on your main drive, but you deleted it yesterday, you can check in Time Machine and you'll see it in last week's backups but not in any you made today. You should always use the Time Machine interface to do this - don't go into the backup folder yourself and try to look around (and certainly don't delete anything you find there), since that will be misleading.
If you did want to delete ALL copies of a certain file from your backup, you should go into the Time Machine interface, locate a point in time where that file exists, highlight the file and go to the Action (gear) menu in Finder and choose "Delete all backups of this file".
It seems that what you actually need to do is make an archive of files you don't need on a regular basis (which can then get deleted from your main drive). Burn them to a CD or DVD, or copy them to another hard drive, but don't delete them from the Time Machine backups (better safe than sorry).
Partitioning is a way to convert a physical drive or other storage device into one or more logical volumes, so that the Finder sees them, and displays them, as separate drives. So you could have a single external drive, but create three separate partitions (using Disk Utility) which mount as three separate drives. Under Mac Help, search for "partitions" - there are several useful documents there.

Time Machine and equivalent of System Restore?

For years Microsoft have had (and needed) a feature called "System Restore" which lets you uninstall operating system updates that may have caused problems.
I had hoped that Time Machine would also provide this capability since uninstalling Apple updates is not really possible. I cannot see any obvious way of doing this. For example, based on the fact that to undelete an email you have to have Mail at the foreground before activating Time Machine I thought it might be logical that if Time Machine can uninstall Apple Updates you would need to first have the Software Update preference pane open. This does not work.
Has anyone else found a way to do this?
While the rest of Time Machine (for undeleting files etc.) is wonderful, a way of rolling back Apple updates (or anyones updates) would be very helpful as well.

AxL wrote:
Yes but +"any changes to any file on the system (mail, photos, documents, etc) would be lost"+ only temporarily.
They are all still on the TM backup, and you can restore them using the TM interface, and there's even an option to recreate a folder that doesn't exist anymore
(better say "that was not yet existing"...)
in the same location or in any other chosen location.
No data loss.
I have since my original post found that booting from the Leopard DVD and selecting restore from Time Machine lets you browse backups to restore from, and that it lists the version of Mac OS X for each. This would make it easy to select 10.5 if hypothetically reverting from 10.5.1 but it also suggests that hypothetically reverting from QuickTime 7.3 would be much harder since all you would have to go on would be a date/time. For this maybe the log in Software Update would be helpful.
Your answer (thanks for it) however does resolve the worry I had about such a restore also reverting user data. Now that you have pointed it out one can of course then do a second restore when back up and running just of the user data.
I would have to say though that this is not an elegant user friendly solution to this particular issue and thus not up to the standards one expects from Apple. Imagine if you are doing this on a machine with multiple user accounts (not unlikely for a home machine). You could also theoretically encounter a situation where you do an Apple update, create a new user, create data, need to remove the Apple update, have to restore the entire machine via Time Machine, and thus lose the user account, and therefore not be able to login to restore the user data. Potentially even if you recreate the user account, it may not have the same exact UID or UIDnumber and thus make restored data inaccessible (users are forgetful and you do not have control over the UIDnumber used).
I still think a more friendly approach would be for the Software Update preference machine to be "Time Machined" like Apple Mail and iPhoto have been so that if you are in Software Update and activate Time Machine it will let you just revert an update without affecting user data.

Using external monitor with a bad logic board???

Can you use an external monitor on your ibook, if you have a bad logic board, to use it? Or is the only solution to use the shim, or get it fixed. Thanks.

Hi, and welcome to Apple Discussions.
If the graphics chip on the logic board has come loose, it won't drive the graphics to an external display, either. Sorry.
