To troubleshoot = diagnotiquer
A trouble shoot = un diagnostic
"Depanner" is more an equivalent of "to fix"
But I realise that for some people to troubleshoot means to identify the source of the trouble and to fix it.
In my mind it just means to identify the source of the trouble.
When I troubleshoot a computer, I just try to find out why it doesn't work, what's the problem.
When I found out the reason, the troubleshoot is finished.
When I make it work again, I fix it.
And when the unit work again, I don't say to my customer: "Your computer is troubleshooted". I say "Your computer is fixed" or "the problem is fixed" or again "the problem is solved"
But I'm maybe wrong.
Does someone can confirm ?
