UGH.Apple warranty ended... :/
Hence the creation of Craig's List. It's much better for computer system purchases, as you can inspect it first, and insist upon verifying operation before paying.Yeah, as they say in Poland, "dupa zbita!"
Buying an expensive piece of used electronics sight unseen is something I would never do! The seller might have sold you a machine that he new was dead, or the damage might have occurred during shipping (I know from direct experience roads are pretty bad in Poland), or even while you were attempting some kind of funky upgrade. Who's to know!? Put yourself in the seller's shoes: why should he buy back a broken computer?
This sort of deal is best done face to face.
That sucks.I just got brand new case for Mac Pro 2008 with new power supply.
And yeah.... it's the same. No boot, no chime, when I press DIAG I got STBY.
It will go to professional service center, because it's out of warranty.
There must be something wrong with power on logic board.
The only problem I got is that there is no serial number at all on both of these cases. Is it anywhere on logic board ?
Did you check here? http://support.apple.com/kb/HT2584
Well, worst case, you have a spare now.It looks like power supply in this shipped Mac is allright, so that must be 100% logic board.
Not a bad price.The cheapest I've found is here: http://www.sunsetmac.com/apple-logi...c-board-for-2-8-3-0ghz-cpu-661-4449-new-p-403
OUCH. That's why I wouldn't buy used systems without first inspecting them and testing it out. Some things you can deal with if broken. But a main board isn't one of them.eBay/PayPal refused my complain, because this refund program is only about transportation problems or not receiving item at all, not quality of products ! They are idiots !
Take a look here....serial number...
It's possible the 3.2GHz systems stripped the CPU microcode for the other parts (2.8 & 3.0GHz), but it wouldn't make much sense to me. I'm wondering if they started with two different boards, but actually decided to use the one you have to save on manufacturing costs, or perhaps had noticed some problem with that for the processors you have.I found that I got a 630-7997 logic board which is designed for Mac Pro 3.2 GHz
So maybe I got wrong processors (Xeon Quad Core E5462 2.8 GHz) ?
It do not start fans even when there are no processors at all...
I'm not surprised here. Schematics are hard to get anymore, especially as most companies don't even do their own board work (ODM'ed).They told me that Apple is not giving them Logic Board schemes, so the don't know how to fix it !
Did you pull the battery when you did this as well?I tried SMC reset, and one time I got OT A - which means CPU A overtemp (I removed front fan compartment).
This is your last course of action to get your money back, so it's worth investigating IMO.I've paid with credit card.
Did you pull the battery when you did this as well?
Might be worth a shot, given the cost of the board. But my guess is it's bad (or the microcode is wrong for the processors).
No. What you did is fine. Unfortunately, it didn't solve your problem.Do I have to start the Mac Pro without the battery and then make SMC reset ?
I hope it works out for you. Good luck.This chargeback seems to be interesting. I will try that. I've paid with MasterCard.
