MacBook Pro :: How To Test Mac Motherboard
May 6, 2012
What is the best was to diagnose possible motherboard faults on a Mac? I'm having various problems which appear to be hardware related (i.e. re-formatting, re-loading OSX, etc don't seem to fix them and the problems appear at different times running different processes) so want to check the motherboard out.Typical problems are a USB hard drive suddening going off-line, the DVD burner suddenly resetting itself for no reason, screen not redrawing properly etc. and all these only happen occasionally. The only test I can find is a RAM test (various programs allow this including Tech Tool Pro 6) but is there a way to test other components?

I have a 17" unibody MBP (early 2009, specs below). It was running hotter than usual the other day, so I F2 booted into AHT to run a diagnostic. The status box within AHT showed 1 second into the 1st pass, and never got beyond that. Several seconds after that status message was displayed, the cursor froze. The time counter never advanced after that, and although I waited a long time, nothing happened. The test froze.Â
I've tried it several times more. It once worked, but every other time has frozen. Checking the "extended test" box, or trying to run in loop mode has made no difference - still freezes at "1 second".Â
I've had this machine for 3 years, OS's Leopard through Lion, and this has never happened before. I last ran a test, successfully, in January. I've not changed any components or suffered any damage since then. Memtest (ver 4.22) says my RAM is fine. (I ran this because the first portion of the AHT is the RAM component.) Aside from the aforementioned overheating episode, which disappeared, my machine's been fine.Â

My son's 17" imac PPC G5 was not booting up. After a trying a couple of things I got it to boot using Disk Warrior and reparing the file directory. At that time I also ran DW's hardware test which said the drive was fine. My son hard restarted it shortly after I fixed it and it wouldn't start up again. Just a gray screen, no apple logo. When I tried to use DW again it told me there were problems with the hard drive and it couldn't fix the problem. I tried to fix the hard drive in target disk mode using Disk Utiltiy and Drive Genius. No luck. So I pulled a working drive out of my Mac Pro and reformatted it and swapped the internal drive of the iMac with it. There were no DIP switches to set. Started up the imac with a Leopard retail disk thinking I would just install a fresh system onto the replaced internal drive of the iMac. Disk Utility on the leopard disk didn't see the hard drive. Now I'm beginning to think it's a logic board problem but I can't find the original disks to do a Hardware test with. Is there some other way to test a logic board? Or some other idea that I'm not thinking of that could be wrong with the machine?

if you recall a thread I started trying to get help on why the Mac Pro was crashing... I finally narrowed it down.After speaking to about 4 different people at apple.... they had me run the Apple Hardware Test off the boot CD.I took out EVERYTHING except the 2nd DVD burner (Apple Branded Superdrive from my old 2.5 Dual G5)... and ran the test.The Hardware Test ACTUALLY FROZE IN THE MIDDLE OF THE RAM TEST.I thought I had bad aftermarket ram... as it wasn't playing nice with the Apple ram when I added them together.Looks like I had fine aftermarket ram... the Apple ram was bad.I REPLACED the Apple Ram with the Aftermarket Ram... and the Hardware Test completed fine.So, now I'm going to be calling them again in the morning and letting them know what happened. I wonder if they'll just let me RMA the bad ram, or if I'm going to have to lug this dang thing down to an apple store.I WONT BE HAPPY IF I HAVE TO DO THAT.Oh, and no more lockups since switching out the ram... and all the other quirks (not able to burn CDs in Windows, sloooow Internet page draws, etc...) are all but gone now.

Strange problem since I got my MB back from the apple store (got a new hd). Now, every so often, the cursor will jump to a different part of the screen, often when I'm typing. You can imagine how frustrating that can be!
Was the case put back together wrong? Hiccup with the motherboard?

I've been experiencing a variety of problems with my peripheral devices. At first it started with my monitor and I thought it was going out... it was having lines (darker lines, like flickering) all over the screen... but then I realized this happened when I plugged something into my computer... so for example if my external monitor is on, and I plug in my firewire soundcard it starts to flickr...
Then it started to do it when I would plug in my printer... now if I plug in my firewire soundcard my monitor turns on and off... and I'm having sync issues with my soundcard.
I wiped my computer, reset the SMC and the PRAM and NVRAM. How do I test if my mother board is crapping out?

Im fixing up a macbook, and there was problems with the battery connector. So I pulled it out. But on the LB there were only 9 holes (6 on one side, 3 on the other) and no hole where the 7th ones should be. And on the connector in those spots it was the same thing, but what is even weirder, is that it doesnt even look like the pins were broken off, just that there was nothing there, and on the top it doesnt have any solder on those points. Any ideas what to do and how to do it??? And if you want i can post pictures.

I sent in my MBA for repair last week to a repair depot, and they say that there is corrosion on the motherboard from liquid damage. The problem with me is that the computer has never had any contact with liquids, especially in the area where the motherboard is. Can anyone show me where the corrosion is on this?

First of all, I understand I committed an error and the consequences are my fault.I bought a MacBook Air for $999. Because of the all-aluminum frame and the no-moving-parts hard drive, I expected it to be durable. Unfortunately, while moving a coffee cup to my lips, I spilled a drop or two of coffee on my brand-new MacBook Air. It shut down in about 30 seconds forever, a total loss. All my data is 100% gone forever. $700 to repair.Of course, I am responsible for my own mistake. Yet, when you start to google: " 'MacBook Air' water", you see legions of customers who have encountered this problem. Couple drops of water in the top--total loss. Why? The aluminum housing acts like a bath tub.

I recently found my old 12" powerbook g4 and I was considering a project to install a new Intel logicboard.motherboard in it to bring it up to todays standards for cheaper then buying a new 15" MBP to replace my dieing 2.2 ghz Santa Rosa model. If I remember correctly my PB only has a bad logicboard and hdd which I will hopefully replace with an sdd if possable.

So a co-worker has a black MacBook that his family managed to spill some liquid on. It no longer works properly, of course. He just wants to get a new computer, so he's giving it to me. I'll get all of his data off the HDD for him and then I can keep the MacBook. It's definitely a big step up from my PowerBook in terms of speed and performance (I'll miss the dedicated card and FW800, though).
I figure it can't hurt to try to clean the motherboard/logic board in the computer to see if I can get it running. Worse comes to worst, I can buy a new logic board for the computer and put it in and be set. Some questions:- What's the best way to clean a motherboard? I've seen everything from isopropyl alcohol to distilled water to just a gentle detergent and warm tap water.
- What's a good way to tell what model the computer is from the serial number? I will get the actual computer tomorrow, but my co-worker can't remember which model it is.From my research it could be anywhere between the 2 GHz and the 2.4 GHz, though he bought it refurbished from Apple last year so I'm guessing it's the 2.4 GHz model.- If the logic board is shot, and it's not the 2.4 GHz model, does anyone know if the 2.4 GHz board can be put in a non-2.4 GHz machine?
It's not every day one comes across a free Mac, so it's definitely something to put some effort into. Once I max out the RAM and put a new drive in (maybe even an SSD in an optibay) the computer should be quite capable.

I am considering buying a new Mac Pro. Can anyone tell me that if I buy one with single CPU, can I upgrade it later by adding another CPU? In other words, do I get a dual CPU motherboard or not?

I was recently given a non working G5 dual 2.5ghz machine. It is a quad core machine with the Delphi liquid cooling system. After some investigating I found it had a coolant leak. All the fans and lights come on as well as the bootup �chime�. I think (hoping) that the motherboard and power supply are still good. My question is this:
Can I use different processors on this motherboard? Lets say a dual 2.5ghz non-quad core processor assembly. Am I making sense? I am very new to the Mac world and would appreciate any help on this issue.

I ordered a i7 15" Macbook Pro high resolution anti glare screen over a week ago. I've been reading lots of forums on the subject and have heard about the small print, yellow tint to the bottom half of the screen, the laptop not sleeping etc.
So I contacted the store to find out about the possibility of returning it if I'm not happy. They said I can spend all the time in the store with it but as soon as I leave the store there is a 15% restocking fee. It hasn't arrived yet but I'm expecting it any day now.
Can someone tell me all the tests I can perform in the store before I leave?

I was wondering if it is possible to replace the motherboard in the iMac 24" (Bought it Fall 09) with a newer, more expandable board.
I have a couple in mind, but I'm just not sure if they will work. If you know of one that will work, thats expandable than shoot me one.

I have Powermac G4 AGP (M7628LL/A) that has the AGP slot without the 'power-supplying' tab at the front of the slot. Therefore my NVIDIA GeForce2 MX video card (ADC/VGA) will only enable me to use the VGA outlet, and not the ADC. I have two Studio Display Monitors (M7649) and cannot use them.
I need to know (1) What other monitors will work with this G4 (in case I cannot fulfill #2), and most importantly (2) Which motherboard can I replace this one with that will enable me to use the video card in it's fullest?

I bought 4 G4 towers of eBay for �85.. none have Hdd's so havent tried them out yet (two also have no graphic cards) I got a mix of ram size and speed (pc100/pc133) however thats not my question
Next to the ram slots theres a red light that comes on, is this normal? I've tried to do some research on it and some people say it is, others say it isnt.
I plan to sell them off again on ebay but I did it mainly as a project to keep the G4's alive. Any suggestions on graphic cards (cheap ones too)?
