Hi,
I have a Macbook Pro 13" A1278 early 2011 i5 with 2 dead USB ports.
(Motherboard model: 820-2936-B)

I looked inside and noticed what seems to be the problem.
An SMD component on the board is missing and I can't tell what type of part it is because it is gone. There is a "brother" part beside it (pictured below) that looks VERY similar, in size, form, and relative position.

First pic shows what i think is equivalent brother part, second shows the 4 points where the old one was, third shows bother parts and their seemingly equivalent...

Hi,
I have a Macbook Pro 13" A1278 early 2011 i5 in perfect condition I picked up from eBay for a steal.

I did the usual, Apple suggested fix, reset SMC, PRAM, OSX reinstall etc.

What happens is, I plug a USB device in, it will light up for half a second and go dark permanently, they work on other computers. They are never recognized by...
