The DC Iinput power jack on my laptop is loose. I've tripped over the cord once too often. I'm actually surprised it has lasted this long, considering how many times I've (accidentally) yanked it out. It hasn't become a major problem yet, as power is easily restored with a quick jiggle or slight adjustment. But a few more well-placed yanks could render it useless. (If I can't get power to the laptop, it becomes a hi-tech doorstop .. soon as the battery dies.)
