I don&#x27;t know about self-repairable...yet. Mine&#x27;s still under warranty, but that&#x27;s almost up and I haven&#x27;t had to use it.<p>I do use it plugged in most of the time, but I suspect that the review is spot on with the battery life. I maybe get a little more since I don&#x27;t do much in the way of video, and I have my screen dimmed and my CPU in passive cooling mode.
