Comment 5 for bug 65249

I don't wish to infer that there is no software problem at the root of this, but I did wonder (because you seem to be seeing this on all kernel versions), after doing some research on this model if you've tried inspecting/cleaning/removing/repositioning the keyboard?

I found some references to the poor build quality and experience of the keyboard, and having had similar strange issues with notebook keyboards in the past that were solved by removing the keyboard and blowing it clean with an air-compressor, I thought it is worth asking the question.

Here's one quote:

"What concerns the tactile feedback, it's a catastrophe. The entire keyboard moves. Besides, the keyboard seems to be installed with a hump. The central sag is approximately 3 mm. Each time you press a button, the keyboard jumps up and hits your fingers. The keys are too soft, accidental key presses are quite possible (you may weigh down a button accidentally, when your hand just lies on the keyboard). But the soft keyboard is good for typing – it's less tiring for your hands. Only the right side is more or less firmly fixed. So it's unpleasant to type, the keyboard strikes your fingers back. As far as I understand, it's a common situation among such models. It's actually typical of blind typing only. For example, my relatives, who type with two fingers only, feel no difference between various types of keyboards. They are all the same to them."
