Hi, According to my source the TCOD is a CPU die temp sensor. As to what it means I have not a clue--does the computer work? If not it may mean the CPU is bad. If the computer works I would ignore it.
I am still trying to research this. It is a temperature sensor problem, I won't commit to the CPU part yet. Strong chance it is firmware related.
Hi AB, Here is a link to the reference I am using. See what you think. http://forums.appleinsider.com/showthrea...
