Hey folks.
Here I am back on day 2 after havin my MBP successfully repaired by a BGA chip replacement
and wanna share my results and thoughts.
May some of You find it interresting or helpful on making a decision how to proceed.
1st of all to all affected owners from Germany or even Europe who search for a trusted company
to get a chip replacement I wanna highly recommend the guys of:
Laptop Reparatur Thüringen:
http://stores.ebay.de/Laptop-Reparatur-Zentrum-Thuringen
They made me a happy Mac user (but of course not customer) again.
Perfect work, perfect communication, (for me) perfect pricing.
I won't hesitate a second to get them If I ever will be in need of such repair.
But now to what happened under the hood of my silverboy.
One root cause only, leading into several different next issues made my MBP die
and from my pov Apple is responsible!
In may case (to assume not only in my case) the thermal compound between chip surface and copper cooler
mutated to a drained heap without any functionality!
This started a silent chainreaction of death.
Without working thermal compound the heatflow gets reversed and goes directly
through the chip making its way through solder balls and finally spreads over the logic board.
As we all now a logic board consists of several layers and from thermal view each layer
has its own coefficient of expansion what produces enormous tension on the board until
solder balls are cracked.
In my case the heat not only damaged my GPU as initially thought but diagnosis of my unit
showed that GPU Vcore and SMC (both are placed quite close to GPU) were affected too!!
And here comes the thing. GPU was not the first faulty component. It startet with SMC chip
in my unit..
Obviously my MBP recognized a problem first time over a year ago
via messages in system.log like:
"SMC::smcReadKeyAction ERROR" and "SMC::Fall back to old SMC mode"
That was all hints regarding a possible problem. I could not recognize any faulty
behavior till finally the chain reaction hit my GPU and its Vcore chip.
The messages above indicate the system seems able to read SMC related info
from somewhere else than SMC itself.
Nice feature if at least some warnings were represented or system protection would work.
One cannot expect users to dig through system log all day long searching for messages they might not
understand or react correctly.
Btw... @Apple
Why in gods name your $2k design wonder is not able to do
what every crappy piece of sh**ty PC hardware is capable of ????
Prevent the system from hardware damage by overheating, give an audio alert and do a emergency shutdown???
This is the second issue I say it is in Apples responsibility if I manage somehow
to accept that they save 1/10 cent production cost per unit
on using the worst thermal paste ever seen..
So to all of You currently running the common gfxCardStatus "Fix" without checkin thermal compound inside
are running a ticking bomb...
If not ensuring a proper working thermal flow system you will burn more than only GPU !!
My advise:
Get a BGA repair with photo proofed chip replacement.
You will end up with 200,- EUR at a maximum and get way better service on such repairs.
