MacBook Pro :: Doing Motherboard Diagnostic?
Jul 26, 2010
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?

I'm very happy with my 2010 MBP 15" i7 -- very slick little piece of kit!
However, there have been a few cases recently where I had to force a hard-shutdown of the laptop (holding the power button for 3 seconds). This is not because of the actual MBP per se, but because of some software that froze and wouldn't let me force-quit them.
Anyways, I'm wondering, since I had to hard-shutdown several times recently, if I should check my OS for any weird happenings? I always, always do Apple > Shutdown, but I've been forced to use the power button recently.

Just picked up the adaptor today and thought it was pretty much a no brainer: plug it in, it works. Not in this case, it keeps getting a self assigned IP address and I can't connect to the internet-although there is a green light next to the ethernet adaptor in System preferences. I have an Airport network set up as a normal scenario. I bought this adaptor only because I am about to take a trip and the hotel only has ethernet in the rooms. I've tried using the diagnostic tool, but it keeps hanging and crashing.

I'm having a periodic problem where my network will timeout. Once that happens, I'm unable to connect to the network again by choosing the network. When I run the diagnostic, only the Wi-fi light is green. If I use the assistance, it tells me the password is incorrect even when I know it's correct. I will always connect for a second or two before timing out or being told the password is incorrect. If I purposefully type the password wrong, I'm immediately told it's wrong without the hesitation of connecting for a second. Does anyone have any ideas of what is going on? I eventually get connected but only after going through a laborious process of either created a new network or deleted all the Wi-fi information. Even then, the process is temporary.

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?

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?

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?

My ATI Radeon X1900XT graphics card keep tripping out leaving a black screen The card itself has a red lcd light visible on the card when the screen is not working
The card is in an 8 core mac pro and is running a 30" ACD.It started a while a go before installed Snow Leopard but happened very infrequently
Have installed snow leopard and added two new dvd drives and I now have these blackout nearly everyday.
Have found info on ATI's website about the Radion HD 4870 suggesting the LCDs indicate a faulty power supply or even disconnected power leadsthe same thread also mentioned overheating could be the cause a of the red light.
anyone know what the Red diagnostic lcds on Mac ATI Radeon X1900XT mean.
Extra info: The two DVDs I have added I had to replace the data cable as I damaged the original
to do this meant a total strip down, while I was there I added two sata data cable threading them through connecting to a new sata drive and leaving one spare for the future.
The DVDs work perfectly, could adding the sata cables have an effect on the power supply.
Having to remove the ATI Radeon X1900XT, I am sure the cables are seated correctly, should it matter which cable is connected to each connector on the motherboard.
There is a thread on apple website about this black screen, all describing similar problems but relating this to Snow Leopard and some sort of video bug.
No answers on that site and no one else seem to have the Red diagnostic lcd

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.

Is it possible that a failing I/O board would not show up as a problem in Apple's hardware diagnostic test? (from disc 1 of those included with the computer). I'm specifically referring to the Left I/O board, which handles the left ports, the a/c adapter, and part of the wireless connection. My battery just fried and now my airport card isn't working, and after trying everything, I think I may have found the issue.

I have a 21" i3 3.06 Ghz iMac. I got it in 2011 and the warranty has expired.Â
Anyway, I notice that every few months after clean installing Snow Leopard, my hard drive would be come corrupt necessitating a complete reinstall of SL again.
This occurs every few months. The OS is up to date, no malware, no weird software of anything installed. Basically, everytime I boot up, it'd take about 5-10 minutes as it does the gray screen with the spinning wheel with a progress bar at the bottom of the screen.Â
I have tried repairing permissions and scanning for errors using disk utilities within SL and via my SL install disc. However, I am unable to repair disk because it is corrupted.Â
Is there any other HDD scanning tools that I can use to see whether or not my hard drive is defective?Â

I recently bought an used iMac (was purchased new in feburary 2009) in which I knew the screen was not showing any video when I bought it. ( I was okay with that I thought I'd give it a go at fixing) well the problem seems to be within the LCD itself. When I hit the power button I hear the chime, fan spins, and the hard drive does it's thing. I ended up taking the casing off the iMac to where it only shows the bottom half of the insides underneath the LCD. My question is now to diagnose what exactly is wrong with it by using the 4 led lights. I have searched the forums and the Internet up and down for which ones mean what but I have only found out information on older iMacs. When my iMac is off (still plugged in) LED 1 is on. When I turn the iMac on LED 1,2, and 3 are green. Which that leaves the 4th LED not being lit up at all. I suspect this has something to do with the iMac not showing any video but as I said I am not sure because I cannot find any information on it anywhere.

My iMac stopped booting. The fans and hard-drive spin up but the screen stays black and I can hear that the hard drive isn't been read after the initial spin up.Â
I decided to open it up to take a look at the diagnostic LEDs to see if it might help me diagnose the problem (the most obvious failure is the logic board). I can't find the LEDs anywhere, where are they? Does my iMac even have diagnostic LEDs?Â
The other possibility is that I can't find the lights because they aren't lighting up. The fans, the hard drive and the CD drive all spin up fine so at least I know that there is some power running though it.

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?

In the PC world, most latest motherboards support either SLI or CrossFire. How about the MacPro's motherboard?
