I normally use on my office chair a connection over a slower network,  
using the grid,electricity network of my home.
So I tested the netbook directly wired to the server over a 1Gb-swith.  
Speed was very good but only for 10 min. Then the keyboard was locked.

Every time it locks the screen moves a little bit from left or right or  
vice versa. The only thing one can do at that moment is Ctrl-Alt-Shift-Esc.

In Belgium and Germany speed is almost Dsl.

The keyboard gets locked. No other input is possible beside  
Ctrl-Alt-Shift-Esc.

No the same problem is repeated

Maybe emails

So, on the local network, on every wifi and with stick same problem.

I have the impression that it has something to do with video rendering
These netbooks don't have much of videocards.

I have one netbook acer with linux on it. Maybe I could try the same on  
this portable.
