Repair activities have been in a long-term decline in the industrialized world; however, for the circular economy and a more sustainable future, repair is essential. To support repair activities through design, we adopt a practice theory lens to examine the user’s computer self-repair dimension. Based on qualitative data from semi-structured interviews and think-aloud sessions with participants with different levels of repair experience, we present a model that can help designers understand and identify the typical factors of computer self- repair practice. This model can aid designers in holistic design solutions that enable, recreate, and continue computer self-repair practice and design systems and solutions accordingly.
