What CE Geek said. On the Epoc versions of the netBook, there was a design flaw that would make the screen cable come loose. Not sure if this effects the netBook Pro as well.
Q. My trusty Psion netBook has started playing up, with the touch-screen often mis-registering my stylus taps. I’ve tried recalibrating, to no avail, over and over again. Does this sound like a repair job?
This is quite a common problem with Psion Series 7s and netBooks. Your screen cable is loose and
(in the worst case
) may need replacing. One quick fix is to press firmly on the ‘netBook’
(or ‘Series 7’
) logo, above the keyboard. This is often enough to reseat the cable and restore a solid connection for a while. If this doesn't work, you'll need to partially disassemble your machine to get to the screen cable. It's not too difficult but don’t try it if you don’t feel confident with this sort of thing and we’re not going to go into too much detail here. Essentially, you remove the logo label between the keyboard and display, then remove the only screw that you’ll see. Lift off the top and then extract the pins that hold the screen. When you get to the screen cable, a semi-permanent repair is to insert a wedge of cardboard between the cable and the base of the unit. Good luck!
