Comment 16 for bug 1028617

My Lenovo has the same problem of the arrow shaking. I unplugged the power cord and it stopped shaking. So then I plugged the power cord in again and the arrow starting shaking. I switched power outlets and it still shook. So then for some strange reason I let one corner of the laptop rest on top of the back of my left hand (while the power cord was plugged in) and the shaking stopped. I tried to prop it up with a folded hand towel and then a piece of thick rubber instead of my hand, and the arrow shook. So perhaps the problem has something to do with vibration and electricity, short circuit, bad design in wiring?????
