Really dead MacBook Pro
Ok, i was brought this Macbook pro A1229 17" model and it's not doing anything. The battery was swollen so i had a friend take it in to Apple to see what they say, but he hasn't gotten back to me.
As for the laptop, it's dead. And i mean dead dead.
It came with a 60W magsafe adapter, and from what i read from Apple, i need an 85W but a 60W will still power the mac up.
So far this is what i have done.
- SMC reset = no response.
- PRam reset = no response. Machine doesn't boot period.
- Pressing key combos = no response. IE Shift+Ctrl+Alt+Power, Shift+Power
All of these i have done and the magsafe has a green light on it. doesn't change, still green and the macbook doesn't boot.
I read on these forums that if i unplug the magsafe, hold power for 30 seconds, plug in magsafe while still holding the power for 10 more seconds, then releasing and pressing the power again, i get some sort of life.
The fans roar on high, the mac appears to boot, i hear hard drive spinup, cd spinup, but no chime, no display, no other activity. And the magsafe has no light. No green and no amber. Just fans running at freakout speed. I hold the power button again to power it off and it does. I press the power again and it starts up and same thing all over again with hd activity, cd, no display and fans on high.
Now if i unplug the magsafe, plug it back in, i get a green light and the mac won't power on at all.
Is this a sign of a dead logicboard, or what?
*EDIT*
There was no battery present for all of these tests.
Forgot to mention, all of this was done before swapping out the ram trying to figure out if that was the problem. And no change. Still dead.
Also took off the original Apple catastrophe they call thermal paste and redid all that by cleaning off the cpu, northbridge and gpu dyes with 70% isopropanol alcohol, and reapplied Arctic Silver 5 thermal paste.
All of this done and still the same symptoms described above.

Ok, well got a loaner 85W magsafe adapter, and it boots. It spins up the hard drive, the cd but that's it. The fans are not roaring, and there is no startup tone. All i have is a dimly lit steady, not flashing white LED. When i close the lid, it brightens up and stays bright.
Even hooked up an external monitor and that stays blank too.
Also, i hooked up a firewire cable, powered up the Macbook Pro and pressed T for target disk mode, and it doesn't show anything on my Powerbook G4. So now i will rule this out as a dead logicboard. Will call Apple tomorrow and see if it's still covered for the Nvidia GPU fiasco.

Well, after doing more extensive tests, i tried booting the mac without ram, and it booted. No tone, no video and steady lit led. So i tried one last thing. Put the ram back in, plugged in the power and after the green light was solid on the magsafe, pushed the power and held it there for 10 seconds. The white led was solid, then it fluttered for 2 seconds, then the infamous 3 short flashes, 3 long flashes and 3 short flashes. Final result, take it in.

Well a major update. After getting the laptop back from Apple who didn't do squat to it, i decided to take a page from the Xbox 360 units. I put the whole laptop back together, except for the top cover, and i disconnected the fan connectors. Then i plugged it into power and turned it on. Basically i was doing a burn in. After 15 minutes, it bonged. Nothing on the screen, but at least it showed some signs of life. From there i powered it down and let it cool for 10 min. After that, i reconnected the fan power connectors and put the top back on. Powered it up it bonged and showed the screen. I am now able to get into the laptop and check temperatures and all. So now it's altogether and it seems to be running fine.

If you are lucky it will stay running for 30 days - like the XboX 360 or PS3 with similar procedure. Thus this is not a fix but a "made it work" for a minute, There is a difference between fixing something and making it work.

Well, so far it's still running, so maybe i melted the BGA solder joints so that it will stay together. I wish i had the X clamp fix for this so it would stay permanent. But right now it works.
