The Problem,
After a time Macbook Pro 2010 Shuts down and re-estart and this is the report:

The solution
If your machine is having some graphical issues spacaially is a 2010 model
MacBook Pro this is a model if you actually do a Google search you won’t
find it if you just go to Apple comm but if you google search you will find a
support Apple comm article on these machines being covered for a certain
graphics issue now the Macbook pro 2011 is famous for graphics issues
the 2008 and 7 ones famous for graphics issues Macbook Pro 2010 is in
famous for a graphics issue but it does indeed have one and I can show you here
here we go intermittent black screen or loss of video quality program so this is
for this model which uses an 8 to 02850 motherboard I had
an older machine where there was an issue with a capacitor on a buck converter the
idea with this buck converter is it turns twelve point six volts into
somewhere around one point zero five volts and when you have an issue with
this capacitor it will drop the voltage and I was talking about this in a video
on recycling and refurbishing and and heating things and talking about how
warranty service centers rather than often try to find the problem what
they’ll do is Oh to shove the board in an oven and it works again and I did a
demonstration with the iron where I tried heating up a that capacitor and
you saw the voltage jump from 0.3 volts to 1.0 5 volts it was obviously the
capacitor and I’m just going to give you a little bit of an overview of what that
circuit looked like over here so we’re just going to open the board that has
that very common flaw and if we look for that board the capacitor
that was heated is right down here so let’s just get this on the screen so
this is a buck converter that’s going to turn one point zero five volts into this
is going to turn 12 volts into one point zero five volts you have buck controller
I see you have your two transistors you have your coil and then after that you
have a 330 micro farad poly tantalum capacitor to ground this is going to be the the battery so to this is an issue that was not figured out by Apple
for the longest time Apple had no idea why this board was failing so if you had
this board replaced under the program they would give you back a board
that did the exact same thing again and this is something that drove a lot of
independent repair technicians absolutely crazy out of their
minds for the longest period of time and what you did had is you had a lot of
people heating the graphics chip in order to make it work again and the sad
part is that it often would make it work again and I want to explain why now in
the video that I did on the tantalum capacitor I showed you on that video and
I’m going to link it here. what I did is I showed you it was
dead and then I isolate I didn’t heat the ground I didn’t heat the big chip
that it was powering isolated it I only heated the capacitor and nothing else
and you saw that it worked beautifully again that’s because the capacitor was
bent so what people are doing is they’re often heating the graphics chip which is
going to be up here and while they’re doing that they’re preheating the entire
board and this heat is going to try and move over a little bit over here so this
is the graphics chip and then you have the capacitor over here so when they
heat the graphics chip they’re actually heating the capacitor and heating the
capacitor they’re making it work again and it took a long time for somebody to
I finally figured out that there was a pattern here is I’m going to put a new capacitor
Loation 
Sacrapping area 
remove andcover with solder 
Replace
I’m just going to scrape away over here
scrape away until I can fit a standard capacitor over here and I
want to see if I can turn it on and boot into the MAC OS without a kernel panic so
the issues would manifest themselves on this board with the screen going black
or a kernel panic and the kernel panic is always going to be something related
to graphics yeah people will think that the issue is a chip but the real issue
is this power rail is fluctuating in voltage and it’s not as catastrophic as
with the older ones again the older models they don’t have they don’t have
the same issue they have the issue with with the mCP and if the mCP doesn’t turn
on then it’s you know you’re just screwed so we’re just going to scrape
away over here we’re going to keep scraping until we get a nice base we can
just extend our solder pad out so that we can put a regular capacitor on there
and we’re going to solder to that I could probably scrape a little bit more,
should clean that if I finish extending it out so you just extend this out yeah
it’s going to make a little bit easier to get a cap on here we’re going to take
a 330 microfarad today same value. yeah this is from Apple store multiple
kernel panics a parenting console related to graphics processor graphics
processor may be failing requiring logic board replacement
Apple doesn’t know what they’re doing check the problem description
customer states machine will intermittently shut off during use
that’s the multiple kernel panics graphics processor may be failing
requiring logic board replacement graphics processor
again this this isn’t even recycling centers saying this stuff at this point
