Hi,

One of the member of my Forum is looking for the Bose subwoofer including the power cable. Have you an idee on where could he find it ?

Thx.

It's missing the step to remove the two torx screws on the upper back side, below the cover with all the holes, after Step 5

Dose anybody know what goes in the top-most chip slot that is empty? Is that for an L2 Cache chip?

To echo the comment from 2014, i just performed this guide and there is a critical step missing between steps 6 & 7. The small plastic grille at the top rear needs to be removed; There are two tabs at the bottom and two on the sides. Flex it to remove. Then remove the two visible torx screws to release the top.
