Teardown of Apple macbook pro retina display 2013

iFixit has performed more of its traditional high-
quality teardowns on both the new 13-inch Retina
MacBook Pro and new 15-inch Retina MacBook
Pro, revealing various improvements to the
components of both that enhance performance, but
also unsurprisingly make both harder to manually
repair.
One of the more interesting changes relative to the
new 13-inch model is that Apple has apparently
reversed its decision to move the 13-inch model's
battery away from the trackpad as seen in the
previous generation of the laptop, instead choosing
to glue the entire battery assembly into the case.
This design is very similar to the battery of the
original 15-inch Retina MacBook Pro, which was
heavily criticized by iFixit for being extremely
difficult and time-consuming to remove without
puncturing the cells.
As Apple stated during its press event, the new 13-
inch Retina MacBook Pro now uses faster PCIe
flash storage, but is still proprietary as seen in the
previous generation and does not allow for easy
replacement. Other changes to the new version of
the laptop include Intel's i5 Haswell processor and
Iris Graphics, the inclusion of only one fan as
opposed to two in the last generation, a rearranged
cabling system, and a slight update to the MagSafe
2 connector.
Meanwhile, the new 15-inch Retina MacBook Pro
reveals a similar internal layout to the 13-inch
model, but includes higher grade components such
as Intel's i7 Haswell processor and Iris Pro
graphics . The glued-in battery system and the
soldered RAM as seen in the previous generation
are also still included, which indicates that no
improvements have been made to the accessibility
of the new model.
Overall, the teardowns of both new Retina MacBook
Pros otherwise yield few surprises compared to the
previous models, and the similar challenges of
proprietary pentalobe screws, soldered RAM, an
integrated display, and glued-in battery system
have led iFixit to award each of the new 13-inch
and 15-inch models a repairability score of 1 out of
10. Compared to the teardowns of 2012
models, the 13-inch Retina MacBook Pro has
scored one point lower than the last generation ,
while the 15-inch MacBook Pro scored the same as
the previous model.
