I have a customer that dropped off an Aluminum iMac (glass panel, Core 2 Duo processor, the current shipping line) that he got as an “Open Box” item at a dirt cheap price ($650ish) with the “full factory warranty” back in late November
the machine would randomly power down and lock up, completely unstable behavior, so I grabbed my copy of Apple Service Diagnostic (a low-level hardware test suite available only to Apple authorized techs) and ran it for a 24 hour loop test…
on the first loop alone, it flagged the following failures;
GPU fan unable to reach a steady-state speed
CPU thermal sensor outside safe range (overtemp)
Hard Drive S.M.A.R.T. tests failed, no S.M.A.R.T. hardware detected
So, I remove the glass panel, front bezel, and LCD display to find…
The Power/SATA/Inverter cable (“Multicable”)exiting the power supply wrapped up in what seems like a cocoon of electrical tape, easily a quarter of a roll, the cable jammed into the cable keepers, and a second long piece of electrical tape holding the cable in position over the power supply
a brownish/gray haze on the metal frame of the machine, classic symptom of a shorted power supply
all four screws holding the power supply in half-screwed-in
two of the chassis grounding screws just resting in their holes, perhaps turned in one thread only
all three sensor cable friction connectors partially seated
it looks like someone did a hatchet job of a “repair”, it wasn’t even a repair attempt
I pull up the machine’s serial number on the Apple database, the machine was originally purchased in January of last year, the customer’s “factory warranty” has ONE month remaining, and the logic board was replaced almost six months ago
According to Apple, the machine was “repaired” by Best Buy
It’s obvious to me what happened, this was a used and repaired machine that BB sold as a “Open Box” (customer return or store demo, not repaired), clearly a mislabled, misrepresented product
It was also one of the worst, most incompetent “repair” attempts I have ever seen, as soon as i lifted the display out of the machine and saw the hackjob done to the Multicable, my immediate response was WTF?!?! WHO worked on this thing?!
I notified the customer and he was NOT happy in the least, he’s going to take the machine back to BB and have a long…discussion…with them about it
If you’re buying Open Box consumer electronics from any of the big-box stores, beware… you never know what might have been done to the machine previously, if the price is too good to be true, it probably IS
this customer should have realized something was wrong with this unit when the selling price was 50% less than a new machine…
