I have done several upgrades to this workhorse machine, all using iFixit manuals and this forum. Last night there was a `wine incident' which I was able to contain and my system was OK until this morning I went to plug in a USB mouse and got a power related error message that told me to disconnect ASAP etc. After that, the (last remaining) USB port is now dead, so now I basically want to see if I can get a Thunderbolt adapter that provides me a USB 2.0 port to do a final Carbon Copy backup before I go and buy a replacement machine! If I am completely out to lunch on this, let me know. Replacing the logic board or replacing the ports are too expensive and out of my comfort zone respectively.
Thanks in advance!
