so today we're gonna be checking out
another MacBook this says the Genius Bar
work authorization so it says customer
states device no longer powers on steps
to reproduce verified devices
unresponsive and owning it using a known
good power adapter the charging LED
shines response that sums to reset the
devices power on give it courage to open
device in manual reset SMC got
permission to reset SMC and that is some
harsh working conditions there at the
Genius Bar we got the permission to
reset the SMC
but device still doesn't power on fans
don't even spin up attempted the short
power on pads while the device was
connected to AC power and had its
battery disconnected the device doesn't
power on proposed resolution device will
need logic board replacement with Apple
turnaround time is five seven days for
75 actually not bad yeah that's a that's
not an Apple price like for 75 oh I know
like that that's not terrible apples
Apple almost didn't rip somebody off Wow
475 for a board replacement Wow
out of warranty - this never happens oh
my god this is this is this is this is
ethical this has to be a no I'm just I'm
just I'm dumbfounded let's figure out
what's wrong with this MacBook damn
Apple did not rip somebody off there
holy [ __ ]
never thought I'd see the day yeah I
should start drinking again so this is
an 8 - 0 - 49 24 board we're gonna check
this out and see why it doesn't want to
work let's get our multimeter on the
screen check out our rails so this is
drawing 30 milliamps and not turning on
one of the only rails I can really check
up here that's a low-level rail is the
BP bus BP bunch g3 odd it is twelve
point six man steady so next up we're
gonna take this board out of the case
and try to figure out why it's not
turning out alright BP bus is there a PP
three before two is there because we got
a light in the charger we're gonna check
out our clock rail clock is three point
four eight five es five is five
daddy ppthe 3v3 s5 is so you but you're
missing huh well see if you're short
it's a ground shorted hmm what is
shorting you to ground so we could
inject voltage into that rail and see
what's shorting it to ground so we're
going to attach
come on you bastard gets odder than that
that's the shittiest solder joint ever
but this is just to blow something
obviously who cares okay next up attach
the ground wire I'm going to take the
CPU heatsink off just in case that
doesn't CPU getting warm because the CPU
does use 3.3 volts holy crap seven amps
and three volts how am I gonna find my
short with all this freezing air oh
that's [ __ ] cold close the door
alright CPU doesn't appear to be warm
know something over here is as I saw
bubbling
oh I can hear fizzing
let's see if you can hear that this is a
DPA forty sixty-six microphone it's
omnidirectional so
that is the DPA forty sixty six playing
the sound of a short circuit being
burned out of motherboard let's take a
look at that area and see what's going
on oh hey look somebody said that 475 is
the Apple price for an old water damage
well what's that does that looks like
some water damage to me that sure does
look like some water damage that's
burning damn look at that there too some
short-circuit right there
that's a nice-smelling short yummy
let's see if our short goes around Oh No
that's short is still there
I cannot live stream I don't believe
like in live stream from the GoPro
pretty cool if I could there's a phone
app for the GoPro but it's so clunky and
slow and painful it's really painful
and sometimes it'll let you download a
file from the GoPro but then you can't
even play it in the damn GoPro app it's
awful ever since you made that analogy
but wiping your ass to get a driver's
clean I just want you know that I think
about you every time I wipe my ass now
but the question is do you think about
me as you dry your ass or do you think
about me as you clean your ass because
if you're thinking about me as you dry
your ass I would be incredibly
disappointed incredibly incredibly
intensely aggravated incredibly
incredibly incredibly independently
aggravated
the disgusting practice of completely
disrespect
[Music]
okay now we just dry off the board
before we turn it on should have paid
your light bill you bought an outfit
fans been fans been oh this is that
piece of crap 2015-16 one with the fan
doesn't spin until it gets really hot
and here we go isn't it is heated the
board and the CPU with a gun got really
hot and the fan is spinning the fan is
spinning short circuit fixed with the
help of alcohol this short was actually
such a simple one you could have just
found it by looking at it so yeah I like
the $900 thermal camera I think it's a
great tool if we sold for $200 but as
you can see the old method good ol
alcohol and alcohol on the short still
works and is very cheap and is an easily
accessible method for people to use if
you do not have the disposable income to
throw away honest dues super expensive
thermal camera and the other benefit of
the alcohol is that once you have all
this alcohol on your desk it makes it
easier to clean your desks so you're
kind of cleaning your desk as the
workday goes look at that folks
look at this clean workspace I've got
