MacBook Pro :: DIY - Test Logic Boards?

Dec 10, 2010

I'm stuck between knowing if my MBP has a bag logic board, worn out plugs going Into it, or other reasons. It will not power on at all. About 5-10 minutes prior it was perfect. The battery had power, and when its not plugged up the green light is very bright. I figure since the I/O board is connected to the Logic and it shows power, that it may indicate its ok. But i dont know, since its not directly hooked to it. Apple / Geniuses and Other shops just give me quotes on changing out the logic board after observation of it not getting power...never have said anything relating to "After Testing the logic board...." So I am wondering, whats the secret? how is it done? CAN it be done at home? or, does anyone know what the shops/techs use to test boards?

MacBook :: Possibly To Replace Logic Boards?

Apr 11, 2010

I have a mid-2007 Macbook 2.16 Ghz Intel Core 2 Duo with integrated GMA950. Now, as you all know the GMA950 is absolute ****. But, I have a close friend that has this [URL] logic board he can sell to me for a pretty cheap price. I am certainly in no condition to upgrade to a newer Macbook as of yet, so this should hold me over for the time being. So, I was wondering if it is possible to install it into my Macbook.

IMac :: Graphics Cards And Logic Boards In Newer

Feb 23, 2009

it appears my graphics card on my old iMac G5 is toast. I took it to the Apple Store and they said they'd have to replace the whole logic board for around $680. After searching around this forum, that does appear to be the only fix. My question is this: is the graphics card on the newer iMacs soldered into place as it was in the older iMacs (G5 and I believe the first gen Intels as well)? Because, if so, that is really lame and may affect my computer replacement decision.

IMac PPC :: Test A G5 Logic Board Without Hardware Test?

Jun 25, 2012

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?

PowerPC :: IBook Logic Board - Software Houses Used Customers To Beta Test Their Products?

Nov 4, 2006

After 3 days of contact with Apple support they have determined that even though they sold units with defective logic boards and the serial number of our unit falls in the range of units with the problem, Apple is not going to honor the replacement or prorate repair since the program expired in August...I thought only software houses used customers to beta test their products

Mac Pro :: No Dual CPU Boards From Intel For PC Market

Mar 12, 2009

Interesting perspective from the PC side of the world... (unlike last generation where Intel launched the "Skulltrail" system based on the Penryn CPU's). Quote:

No plans for Nehalem Skulltrail from Intel

Nehalem might skip it

Intel told us that they won't do a reference motherboard for Nehalem dual socket, super desktop machine but there is still hope that partners will do it. Intel has told us that partners can do it, and it will be up to Asus, MSI and Gigabyte to manufacture one.............

MacBook Pro :: Apple Hardware Test Freezes, "one Second" Into The Test?

Apr 9, 2012

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. 

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". 

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.

Mac Pro :: The Hardware Test Actually Froze In The Middle Of The Ram Test?

Feb 27, 2008

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.

MacBook :: Replacing C2d Logic Board With Cd Logic Board Cause Heat Sink?

May 13, 2008

so i've got a system with a fried c2d board. i can pick up a cd board for $150 plus shipping which is good for me. to find a comparable replacement, i'm looking at ~350 and i'm just not feelin that price as im on a budget.

i'm not concerned about the speed decrease as im just trying to get this thing rebuilt.

i understand that there are different heatsink assemblys..vertical vs horizontal. however, i do not know how to tell the difference and i am also unsure whether or not my c2d heatsink will work on this board i receive.

the logicboard possess a t7300 c2d and model # is 820-2279-a, it appears.

i cant find anything on that model, except for on ebay.

and i totally cant find the serial number on this macbook. under the battery on the tray has no serial number listed, and i've read through this documentation [URL]

Applications :: Where To Find Logic Express/Logic Pro

Is it likely? Aperture is a pro app and is on there, and it'd make sense if they also added Logic and Final Cut - it'd be like a professional version of iWork with the whole set.

MacBook Pro :: What Are All The Tests I Can Do To Test?

Apr 28, 2010

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?

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?

OS X :: How To Test A Macbook With Broken Screen

Aug 18, 2010

I just found a working macbook with a broken screen being sold for $60 on craigslist. I asked the seller for specs and she said she doesn't know the details except for the model # (which is A1181). It comes with no power adapter or software.Is there any way I can I test the computer to know if it is worth buying when I get there? I want to make sure it is able to run properly before investing in a screen. I have a 13" macbook. When I was at the apple store today, the employee was able to run diagnostics on my computer with his MBP without having to touch my computer. (Edit: There was a cord running between both computers, and my comp. was running, but everything was being done through his OS). Is there an easy way for me to do the same thing?

MacBook Pro :: Can't Get Apple Hardware Test To Run

Apr 7, 2012

I purchased my Macbook Pro (Early 2011) 2ghz i7 edition, about 4 months ago now,

Earlier today my MacBook Pro ran a grey bar update during start up started up & ran a little slower until I restarted afterwards. I was concerened until the restart, however I am no longer concerned. My main issue is that now I can't seem to correctly follow the instructions to successfully start an apple hardware test. I have previously owned a Mac mini, Powermac G5 Dual 1.8ghz and Powermac Quad G5 and I have always been able to successfully run apple hardware tests on them.

I held down the "D" key during startup prior to the grey screen and I tried plugging in a ethernet cable, the powercable and a USB keyboard all to no avail.

MacBook Pro :: Will It Run Normally After Use The Apple Hardware Test

Jun 3, 2012

I've been having issues with my 2011 MacBook Pro, I just keep getting a weird error popup but it always flashes up and goes away before I can read it. My Mac has also even running a bit slower lately and I know that I can do the Apple Hardware Test to check out that all the hardware is functioning properly. But will my Mac continue to run normally after I do the AHT? Like, will I be able to use it as I was before?

MacBook Pro :: OS X (10.7.5) - Apple Hardware Test Not Loading

Aug 30, 2014

I have a MacBook Pro (17-inch, Late 2011)  using OSX 10.7.5

Trying to run Apple hardware test as my computer keeps crashing, or shutting down 30min in.   I restart while holding down "D" and nothing comes up. takes a while to startup, but then goes straight to desktop.  What am I doing wrong?  I'm ethernet connected to internet.  When I bought the computer I installed an SSD HD. I remember when needing to install new software on the new drive it was a nuisance since the computer didn't actually ship with any software CDs.  Had to do it over the internet somehow.  The computer didn't have any problems before so never had to use AHT until now. 

secondary question.  I also reset SMC, by pressing left side shift+control+option+power key after shut down, but didn't get much response out of that either.  no sound, or signal that what I did actually reset SMC.  How would I know it reset or not?

MacBook Pro, Mac OS X (10.7.5), 16gb 1333 mhz ddr3

MacBook Pro :: How Long Does Extended Apple Hardware Test Take

Nov 25, 2009

I'm running one on my mid-2009 15" MacBook Pro with 4Gb RAM. It appears to be taking forever as it tests memory. It's been on Pass Number 2 for around 30 minutes now. The progress bar is either completely stalled or moving VERY slowly. Is this normal for the extended AHT? This is the first time I've run the extended test. I ran the quick test just prior to this one and it returned no errors.
