How do I know if the logic board is bad?

So the girlfriend dumped a slew of water on her 20 gig 4th gen photo. I've completely disassembled it and THOROUGHLY dried it out and all seems well from that perspective.
So here is what is happening:
- if I plug it into my PB it does not respond, nor does it start to charge
- if I do a "restart" (menu + center button) with it unplugged I get the exclamation point with the battery (low battery indicator)
- if I do a "restart" while it is plugged into the laptop, I get the lightning bolt with a battery (battery is too low to be recognized by computer)
- if I plug it into the regular AC charger, I get the same results
- if I try to "restart" again, the screen goes blank and then the lightening bolt comes back eventually
I opened it up again and took a volt meter and measured that the battery is still good; I get 3.8V I think or something like that from the red and black wires of the battery. Plus this thing is only like 8 months old, so I know the battery isn't bad.
This leads me to believe that the logic board is bad b/c that is what the battery plugs into. The screen must still be ok b/c it looks fine.
So does anybody have any ideas?

OK, so I have answered my own question. I ordered a logic board and put it in. So I know the logic board was bad.
However, now I'm pretty certain the hard drive is bad too as it just spins but won't do anything. I don't even get the folder with the exclamation point- just the big apple like it is booting up.
So I'm looking for a hard drive unless someone has a better idea???

How can I tell if the logic board is bad?

My mom has a flat-panel iMac (20") that has been refusing to boot since this past weekend. My sister and I tried every trick we could come up with to get it to boot, but the only thing that resulted in anything other than a blinking question mark was powering up while holding the eject button. This caused the computer to boot up from the external firewire hard drive. We were not able to get the disc tray to open, so we couldn't start up from the Hardware Test CD. I have two questions:
Is there a way to physically force the tray to open? (We've tried all the suggestions offered by Apple Support, to no avail, and the iMac has no hole for the old paper-clip trick.)
Is there a way to tell whether the hard drive is dead or the logic board is bad? We strongly suspect it's one or the other.

Hello! You have one or two problems and both are likely related. The fact that the cd/dvd drive isn't responding indicates problems with it however it could be related to the hard drive problem. The fact that it will boot from another source indicates that the logic board is ok. If you like to tinker then you might want to consider buying a new computer and using the one with problems to learn more about working on one. I've never been a fan of all-in-one type computers because when component goes out you either in for a difficult job in repairing it yourself or you forfeit the value on the component (s) that are still good. That's why I personally think towers are better long term values. Sure they're not quite as "cool" as the iMac but I'd rather pay for computing power and long term useability. Tom

I havea 2007Mac Book Pro and a Genius told me that it is "vintage" and that the "logic board" is bad. He removed the hard drive and told me to buy a "sled" to retreive the data. Is it worth trying to fix it so that I don't have to buy a new one?

I have a 2007 Mac Book Pro and a Genius told me that it is "vintage" and that the "logic board" is bad and no longer supported. He removed the hard drive and told me to buy a "sled" to retreive the data. Is it worth trying to fix it so that I don't have to buy a new one? Where should I take it? Thanks.

djgornik,
if the Genius is correct and the logic board is bad, then replacing the logic board would be fairly expensive. What problems are you seeing with your MacBook Pro that caused you to visit the Genius in the first place? Whether it’s worth trying to fix it or not depends on your particular circumstances, such as your willingness to trade time for money in pursuing repair vs. replacement.

How do I get to the logic board on a PSC 2210?

Does the logic board affect battery performance?

Anyone know of any issues at all?
Cheers

Yeah sorry. It's just that i had my macbook pro repaired due to a faulty logic board. It's a known problem and covered by Apple, so the repair was free. Since it's come back the battery is not working properly. Never had a problem before with it. I suspect that that they've given me someone else's duff battery. However, I'm investigating the possibility that the battery is fine and it's a faulty logic board that is causing the power problems. The battery used to tell me at about 10% to plug in my power cord, and even when i didn't it just went to sleep - as in after getting a dose of power all the programs were open that i was using etc. Now it shuts down at about 35% power.
Does anyone know if the logic board repair could be causing the problem?
Cheers

How do I get the logic board serialized?

I had the logic board replaced a year ago in my iMac. Ive been having some problems sharing maps with my other mobile devices. Someone suggested to check to see if the logic board is serialized. Anyone know how to do this?

Go to About this Mac in the Apple menu.
Tap the version number twice. If you see a serial number, it has been set. If not, then take it to an Apple Store or Service center and have them fix it.

How many times did you change the logic board?

Hello everybody,
I"m the formerly proud owner of an iBook G3. Solowly I"m getting tired of the logic board problem. I have AppleCare, but by now I"m sending my iBook twice a year for repair!
By now I had my iBook sent to Care 5 times due to the logic board problem.
Now I"d like to know if this is average, low or high ranking on the G3 exchange scale,
Who can beat 5?
Michael

Michael,
Mine has been back three times.
If your iBook's logic board goes out again, I recommend that you call Apple and, instead of talking to Customer Support, immediately ask for Customer Relations. Be prepared with dates and details of your iBook's repair history, tell them you need a computer that is dependable, and your iBook just isn't. Then ask for a replacement. It has been known to happen.
Good luck.

The logic board on my MacBook Pro has failed. How do I retrieve all my data from the hard drive?

The logic board on my MacBook Pro has failed. How do I retrieve all my data from the hard drive?

Remove the drive and put it in an external enclosure. Backup the drive completely. Repartition and format the drive. Replace the drive into the computer. Take the computer in for the logicboard replacement.

My mac book pro crashed and the logic board died. They said that i could get the hard drive out and it should have all my files on it. How do i get them off and put them on my new computer?

Does anyone know what the second button is for on the logic board of an iMac G5 (PPC), 1st generation ?

One button on the logic board of a 1st generation iMac G5 (PPC) is an alternate power button. Does anyone know what the purpose of the other button is?

I am far from certain but I believe it is the power management unit (PMU) reset switch a/k/a Cuda switch: http://support.apple.com/kb/HT1939
Do not press it when the computer is on.

I have been trying to get my ibook g4 fixed from apple for 6 years now. my ram doesnt work and the logic board is f'd up aswell... i know 12 people that have had the same issue. 4 of them got there ibooks replaced. anyone know what to do?

Apple supports most of their computer products for a 7 year period, could be that your IBook is well past any kind of help.Secondly parts are no longer being made for this machine and never will be again. Finally I find it hard to believe that nothing has been done with this for 6 years.Have you documented the reasons why you were turned down for repairs ? were the replaced Ibooks within a couple of months of warranty expiration? What model is your IBook ? At least if we knew what the model #, some of the more techy types could find out if there were any repair programs for your model.
Seems odd that you'd hang on to a non-working IBook for that long.

Hi - my 2011 Mac Pro no longer recognizes devices in the usb ports, I've been told it's the logic board. is there a way I can connect the iomega external hard drive to it through the firewire or thunderbolt ports?

Ok, fair enough. But since Job's death - Apple's control on leaks has been terrible. I got the new iPhone, and I like it - but it hasn't made nearly as big as an impression as previous ones. Because of the vast ammount of leaks. With the iPad mini leaks, it's 99% sure to come out next week.
Apple uses many manufacturers and it's massive also websites prefer to report on Apple whether true or false because it brings more hits.
Amd by "others" I meant other people on iPads - not other devices/manufacturers. It's possible to do so, I just want to know how. I honestly don't think we'll ever be in a Post-PC era until all tablets allow us to use USB in the way computers do.
No, USB is not the future, you missed the memo about cloud and wireless computing?

(HELP) Dead MacBook Pro.. possibly something to do with the logic board.

I had been noticing my MacBook Pro's performance degrading lately.. for example whenever I dragged a file into a folder it would lag for 5-6 seconds and then copy over. It started to bug me so I guessed that maybe a reinstall would fix the problem. After reinstalling and rebooting, I got no video on the display.. keyboard wouldn't work.. only things that happened was the disc drive made a sound, light came on the font and could hear the HDD spinning a little.
I then took it to the Apple store as thats what Apple told me to do on the phone. So we took the loverly 3 hour drive(there and back) to the closest Apple store just to have the man take it out the back for 2-3 minutes and then come back to say "It's possibly the logic board that is dead".
I am out of warranty by 2-3 months and so he told me I would have to pay £700 or so to repair. As a full-time student I don't have that kind of money.. I don't even have £60. - I find it annoying how they didn't even fully check the problem out.. just a "possibly the logic board".
So what if I manage to click my fingers and have £700 appear right before my very eyes? I pay for the new logic board just to find out thats not really the problem? or maybe have the same thing happen again right after the 90 days that logic board is covered for? meaning I have to fork out another £700.
I am a massive fan of Apple.. I love their products. I have brought so many products of theirs.. now just 2-3 months after my warranty runs out.. I get this. They didn't even say sorry for selling me a faulty product and didn't offer to help out in any way. When I spend £1,299 on something I expect it to last A LOT longer than a year and 3 months.
I need my MacBook Pro very badly for College but now I can't do my work and if I want to do my work, I have to pay £700 for it.
What do I do? Who do I talk to? Is it possible to get it fixed without having to pay that kind of money?
I can't settle for anything less than a Mac. I love the OS way too much and need so many of the apps that are Mac-only. So no way am I going to forget this and buy myself some cheap PC CrapTop.

Unfortunately, if you cannot boot from the disc, it won't be possible to do any diagnostic tests yourself.
It might be worth getting a second opinion. Is there an Apple authorized repair shop anywhere near you? If so, possibly you could take it there and see if they can diagnose it. You may need to pay a small fee for them to do this. But possibly someone might take a little more time with it and be able to give you a definitive diagnosis.
I'm grasping at straws, but you might be able to try resetting the SMC:
http://support.apple.com/kb/HT1411?viewlocale=en_US
I don't know if this would help or not--there are not many things to do when the computer is unresponsive and you can't use the keyboard or a disc.
Unless the problem was reported to Apple while the MBP was still under warranty, I don't think there is any way that Apple would be able to fix it under warranty. Did you ever take it in for any problem under warranty that might relate to its current situation?
I don't know if you might be up for trying to fix it yourself. If you are, here is a site that might be of help:
http://www.ifixit.com/
You have my sympathy--this has to be an exceedingly difficult situation for you. I will continue to think about this, and will post back if anything comes to mind.
Good luck!

Am I still elligable to the logic board progam?

Bought an iBook G3 in 2002... But it seems to have decided to wait until now to show Logic Board problems... The serial number in right in the middle of the elligible ones... But it is more than 3 years old obviously... Does anybody knows if I will have to pay for the repair, and if yes how much??
iBook G3 14'' Mac OS X (10.4.2)

My screen started having problems - opening up to a sky blue screen with no ability to work with it. A few days later it just stopped lighting up at all. It turns on and off. After reading the discussions here, I did check to see if my serial number fell within the range of serial numbers with the problem - and it did. (Read about that in another email.) I looked up the logic board replacement FAQs.
The first time I called Apple about the problem, the guy said that it would cost $745 at a minimum to get it fixed.
That answer didn't sound good, so I looked up these discussions and learned that people are still getting their ibooks repaired for free.
I called again and got a different person. I explained that my ibook fell in the right serial number range for the logic board replacement even though the deadline on the offer is supposedly over. I also told them that I'd just invested four hundred dollars in my iBook.
They asked me to wait, and five minutes later I was told a box would come for me to send my laptop back. I'm greatly relieved, but that was Sunday, and I still haven't gotten the box, so I hope it's not slipped through the cracks.

How can I complain about a logic board failure after warranty??

My iBook G4 12" has been diagnosed with logic board failure. I just bought it 1 year and 2 months ago..and the tecnhical service charges me US 820!!! for change the logic board (more than the half of the original price of the notebook!!!). I can't believe that a notebook could die so soon. I live in Chile (SouthAmerica) so I don't know how can I complain to Apple..I think they should respond for this because is a fabric failure right?

The Danish government is pressuring Apple to admit this is a design flaw, but so far they have not commented on the subject. If you have local consumer protection agencies, you could try making a complaint to them about Apple, but I'm not sure I like your chances.
