First, don't use insta-repair on your computer for this task, I think it's broken it.
So, I finished the task of putting in the doohickey into the computer (the How Low Can You Go Deskblock Computer). I used a sim that had finished the knowledge aspiration, Nerd Brain, so I had the option to insta-repair the computer, which I did. This didn't count as repairing the computer, and I don't know what to do now. I could try to use the gremlins lot challenge to re-break it and fix it normally, but that would be difficult as I have 6 sims in the household currently. I'll comment what happens when it breaks again.
I do have mods like mccc, but I don't think that would make insta-repair not count for the mission task.
