11:02.4
Alright, I'm gonna hit the pause button right there,
11:02.5
11:07.3
because this is where things just get from bad to quirky.
11:07.5
11:09.7
But we maybe found some stuff out.
11:09.9
11:14.8
I took some time to contact my buddies at Mac Yak, these guys are way smarter than me.
11:15.0
11:23.2
I was talking with Greg, the host of the Mac Yak show and Jay, primarily, Jay asks me what model PowerMac is it.
11:23.3
11:25.3
And to be honest, I had no idea.
11:25.4
11:28.0
I didn't boot it up, I didn't look at the system profiler, nothing.
11:28.1
11:31.3
So, I went back to the photos that the donor sent me.
11:31.9
11:34.4
These photos show that the computer was working just fine,
11:34.5
11:37.3
but I go to the system information and I tell that to Jay.
11:37.4
11:41.3
He says, "Oh, you have a liquid-cooled one,"
11:41.9
11:42.3
And,
11:42.4
11:44.5
I had to change my pants.
11:44.7
11:48.9
I had no idea that this was a liquid-cooled system.
11:49.1
11:55.9
The joke I made earlier about the reactors inside this computer, I was actually not very far off.
11:56.0
12:00.5
What we're dealing with is kind of similar, you know, radioactivity and everything else aside.
12:00.6
12:03.5
So Jay gives me basic instructions on how to access the pumps.
12:03.6
12:08.5
I take off the covers and boom... Lo and behold, there are pumps.
12:08.6
12:11.1
There's pipes, there's coolant.
12:12.3
12:13.6
There's coolant.
12:14.1
12:17.3
Yeah, there's coolant where there shouldn't be coolant.
12:17.3
12:23.2
Something is dripping, something is leaking, and thanks to Apple's amazing engineering,
12:23.3
12:26.9
the power supply is located right below where the liquid is.
12:27.0
12:28.6
Why? I don't know.
12:28.7
12:29.9
(sound effect)
12:30.0
12:31.8
Upon this discovery, I was surprised.
12:31.9
12:36.1
And I was thinking "Well, this liquid might be non-conductive, right?
12:36.2
12:38.1
I mean, that's not super uncommon,"
12:38.2
12:38.8
WRONG!
12:38.9
12:41.0
Yeah, apparently wrong. I didn't know any better.
12:41.1
12:43.0
Greg Hrutckay from HrutckayMods,
12:43.1
12:45.1
he's also on the Mac Yak show, by the way,
12:45.2
12:47.7
reminded me of something really important.
12:47.9
12:54.9
This was one of the first, if not, the first commercially available personal computers to ship with liquid cooling built-in.
12:55.0
12:58.1
So I guess that means, not all the kinks were worked out.
12:58.2
13:01.9
The coolant in this thing is GM Dex-Cool.
13:02.0
13:05.8
This stuff is corrosive and conductive,
13:05.9
13:13.1
so if it did leak out, which it looks like it did, and got into the power supply, that is what caused the short.
13:13.1
13:15.5
Another theory was that I blew a cap.
13:15.5
13:16.3
Possibly.
13:16.4
13:19.3
Again, I'm not an electrical guy, I'm not really too into that,
13:19.4
13:22.9
but I think I would have smelled that if a capacitor exploded.
13:23.5
13:24.9
I didn't smell anything.
13:25.0
13:28.2
The sound I heard was an arc.
13:28.3
13:36.5
I didn't mention this earlier, but there was a flash. I could see a flash in the power inlet right when the flash happened is when I heard the sound.
13:36.6
13:41.2
So that popping noise was an electrical arc, not a capacitor blowing.
13:41.2
13:43.4
So I think we can put that theory aside.
13:43.4
13:46.0
So now, we're dealing with this. There's liquid.
13:46.0
13:49.7
Jay wanted to make sure it actually was... coolant liquid.
13:49.7
13:54.9
I dab some up and the properties resembled that of coolant,
13:55.0
14:02.2
not of typical water where it would just dissolve up pretty easily into a napkin and evaporate on the surface of metal pretty quickly.
14:02.5
14:06.3
It's... it's remaining there, it's like smearing kinda and it felt kind of oily.
14:06.4
14:12.0
I noticed there was some liquid, even on the foot of the computer and it felt oily, it did not feel like water.
14:12.2
14:16.9
But to add to the complexity, 'cause this wasn't already (beep) up enough,
14:17.0
14:22.4
I go back to my emails from the donor and recall that this thing was in a water sprinkler accident.
14:22.6
14:25.3
What the shit? Seriously.
14:25.4
14:28.5
So, now that was mixed into the equation.
14:28.5
14:33.2
But thankfully, I think it's fair to say, we
14:33.2
14:37.3
can quickly remove that from the equation, judging by the fact that the donor sent me photos of the computer working.
14:37.3
14:41.6
So whatever incident it was in earlier, that issue must have been rectified.
14:41.6
14:49.6
This liquid is not water from the sprinkler incident or from poor storage or any of that stuff, it is from the cooling system.
14:49.6
14:56.1
So now we're stuck with the power supply that likely has liquid in it, so the computer is inoperable.
14:56.2
14:57.0
Could it be fixed?
14:57.1
14:57.8
Potentially, yes.
14:57.9
15:02.8
The power supplies of these things are kind of a bitch to remove and I don't want to futz with it,
15:03.0
15:06.3
nor do I want to ship this out to get it repaired because,
15:06.4
15:07.3
one: it's expensive,
15:07.4
15:09.8
but two: it's probably gonna get damaged even worse.
15:09.9
15:12.4
Even if it got fixed, it would still have to be shipped back.
15:12.5
15:14.9
My theory is, during the shipping,
15:15.0
15:17.0
even though this thing was packed brilliantly,
15:17.1
15:20.2
it still got jostled around and there was a leak.
15:20.3
15:21.8
I'm open to suggestions.
15:22.1
15:28.3
I'm open to ideas of where I can maybe find someone to fix this locally,
15:28.4
15:31.2
but to be honest, I don't know if it's worth the hassle right now.
15:31.3
15:32.8
So that was my discovery.
15:32.8
15:34.9
Thank you, Mac Yak guys for helping me through this.
15:35.0
15:39.5
Oh yeah, and there was this warning that I totally missed the first time on the inside that says,
15:39.6
15:43.0
"If you see liquid, you know, turn off the computer, yada yada yada,"
15:43.1
15:45.5
Yeah, I, yeah, I didn't see that before.
15:45.6
15:47.3
I don't know, maybe it was covered up by something.
15:47.4
15:48.7
Huh, got a read.
15:49.0
15:51.0
Let's get back to the tech video blog.
