Need help with diagnostics - unexplained shutdowns
Apple MacBook Pro "Core i5" 2.53 17" Mid-2010 Specs
Identifiers: Mid-2010 17" - MC024LL/A - MacBookPro6,1 - A1297 - 2352*
I need some expert advice on how to proceed on this one. A customer came in and wanted me to replace the upper case on a 17” MacBook Pro because of some water damage. I looked up the prices on line both on IFixit and Powerbook medic in front of him,
Apple Part Number:
Manufacturer Part Number:
He does not like my prices and leaves. He returns about a week later with a part he has purchased from PowerBook Medic:
613-8590-A, not the 613-8590-02
it is new and was a higher price than what I quoted, I do get a very small, about 5% price break since I am a reseller.
I am given one day to do the job. The customer returns the next day just as I am screwing in the bottom case. I hit the start button and it starts up. He takes the machine and leaves.
A couple of days later he returns and states the machine is shutting down on him unexpectedly and sometimes won’t start and implies that it never had this problem before, it worked fine with an external keyboard and it’s my faulty installation that caused the problem and wants me to fix it.
He also brings with him a new 500GB SSD drive and RAM upgrade for me to install.
I pull the hard drive, format the SSD externally on a faster machine and dupe it.
After duping I run Symantec anti-virus and find 205 viruses including:
OSX.Malcol, OSX Malcol.2, Backdoor.Graybird, PUA.Yontoo, Trojan.Gen,Trojan.ADH.2,Trojan.Gen.2, SecurityRiskBL, SecurityRiskON, OSX.Genio, OSX.Genio!gen1, gophoto.it Installer, Trojan Horse, PUA.RegCleanPro, PUA Yontoo, Trojan.Ransomlock.Y, Suspicicious.Emit, AdwareMaltrec.TS!g5, Adware.Clkpotato!gens, PUA.UpToDown, plus a load of .exe files.
After cleaning both the old and new drives of viruses I try both in his machine. It continues to exhibit the same behavior of either not starting or starting up to a white screen and then shutting down on its own. When it’s cold it will boot normally, as it did this morning. Ran fine and I downloaded a system update to 10.10.5 on his old virus free drive. After being on for 30 minutes it shut down on it’s own. Trying to restart I get a flash of LED on the front, sometimes a small click but nothing else with both old and new drives. In the expert opinions of the top professionals here, what do you think the problem may be? Is there any possibility or omission I may have made in my uppercase replacement that may cause this erratic behavior? I cannot run AHT because it will not stay on long enough. I know what I think it is but would appreciate inputs from the top techs in the world.
On the replacement part, the original top case came out of Saudi Arabia, the keyboard is slightly different, refer to photo. Suggestions on how to proceed would be appreciated!
