When I was using my tablet today I noticed that the new piece of dust (mentioned in last night’s post) had slipped down to the edge of the screen. It was only visible from an angle and I only noticed it when the Portege was in portrait mode. After my meeting I turned my M400 off and put it into my bag. Then I walked out to my car and drove home.

When I arrived home I got my tablet out and set it up in notebook mode. The piece of dust was back inside the visible screen area. Now it’s about one third of the distance from the right hand side of the screen and approximately 10mm up from the edge. You can see it in the photo (and yes my family thought I was a bit crazy photographing the screen of my computer!).

This must mean that there is some sort of gap between the layers of the screen and that movement of the tablet flexes the layers sufficiently to allow the dust to move.

Yesterday when I made the call to Toshiba Tech Support the technician suggested that to have this issue I must be working in a dusty environment. I will admit that I hate housework but need to make the point that there is no dust trapped inside any of the other equipment that we have here. I could (almost but not quite) be described as anal with regard to the care that I take over my electronic equipment. I am forever brushing out keyboards and cleaning screens. I have an eighteen month old pocket pc here (with a carefully applied screen protector) and have had no issues with dust inside its layers.

Anyway, I am going to map the path of the dust over the next day or so and then take the unit into a service centre. It could be interesting!
