whether your MacBook Air isn't charging
it's not outputting sound from the
headphone jack or the USB connection is
wonky the problem could be traced back
to a single source the i/o board and
because the i/o board is responsible for
so much stuff simply replacing it could
save you from having to buy a whole new
computer hi I'm MJ with iFixit and today
I'm going to show you how to replace the
i/o board in a late 2010 MacBook Air if
you own a 2011 version of this computer
the process is remarkably similar but of
course you're still going to want to
follow the step by step instructions and
the repair guide on our site when you're
performing your repair we'll even link
to it down in the description to make it
easy for this repair I'm going to need a
plastic spudger a t5 Torx driver and a
macbook air pentalobe driver now rather
than using separate drivers I'm just
going to use our 54 piece bit driver kit
because it has both the bits I'm gonna
need plus a ton more I'm also going to
use an anti-static wrist strap to
protect my MacBook Air from any
accidental electrostatic discharge
during my repair and a screw tray
because it keeps all those teeny tiny
screws nice and organized now I've got
all the parts and tools together I can
get started by taking out the 10
pentalobe screws that are holding the
bottom case in place
now that I've got all those screws out I
can begin to remove the lower case by
grabbing it right between the display
assembly in the lower case and rotating
it towards the front of the computer now
that the lower case is removed the very
first thing we're gonna do is disconnect
the battery and really that should be
the first step in any electronics repair
because we don't want any residual
electricity floating around in there
while we're doing our repair to
disconnect it we're gonna grab the
little pull tab and pull it out parallel
to the logic board you don't want to
pull out vertically because that'll
break the connector now that the battery
is disconnected I can disconnect the i/o
board cable and for that I'm going to
use my spudger
now that the i/o board cable is
disconnected we have access to the fan
cable that's connected via this teeny
tiny little ZIF socket I'm going to use
the pointy end of my spudger to flip up
the flap on the ZIF socket and then pull
that cable right out
now that the fan cable is disconnected
we can begin to unstick the gasket off
of the fan it's held in place by some
adhesive so all you need to do is is
gently lift it up and off
now we have access to the three screws
that are holding the fan in place so
I'll go ahead and remove those
now that that Laster is out the fan
should lift out pretty easily now the
first step to removing the i/o board is
disconnecting all the tiny connectors
that are holding it in place and for
that I will again use my spudger
with all those cables disconnected
there's only one screw holding the i/o
board in place so I'll go ahead and
remove it and with that screw out the
i/o board should lift out pretty easily
before I do that I'm gonna make sure to
D route this cable because I don't want
to go ripping it off when I'm lifting
the i/o board out and that's it
all I have to do is install my new i/o
board and reassemble my computer of
