The complexity of the repair was mostly to keep track of the myriad screws involved in stripping out nearly everything. I still have one screw "extra" and can't find where it goes. The video had colored circles around the screws to aid recognition, but the colors weren't consistent so no way to keep them properly separated. Also a number of suggestions at the end to avoid removal would have been better read in the beginning. Still haven't connected the battery and buttoned everything up but hope to have a functional machine soon. (Aso found that the right speaker cable popped off the mainboard and am trying to reattach it, but about to give up because the left speaker should be enough.)
