Question about HP Jornada 690 Pocket PC

1 Answer

Touch screen problem

I recently purchased a Jornada 690 and I'm trying to determine if it has a problem with the touch screen. It seems to take fairly firm pressure from the stylus in order to register that I have clicked on the screen. I takes quite a bit of pressure to do the initial touchscreen calibration also. During calibration, it will not respond to a simple tap on each cross-hair location. It requires a firm press at each location. This would not be a problem, except that with light pressure the screen will sometimes reads the stylus position incorrectly and does things I did not intend. For instance... If I have the control panel open and click the close box in the upper right corner... If I apply firm pressure, the control panel closes. However, if I apply light pressure to the close box, one of the control panel icons may highlight instead of the control panel closing. I have also been able to illustrate this in the ink writer application. If I draw a vertical line and firmly press the stylus I get a nice vertical line. However, if I use lighter pressure while drawing the vertical line, instead of just skipping the spots where the stylus pressure is too light, the line jumps across the screen at times usually toward the center of the screen. I don't think this is normal. Any help would be appreciated.

I have seen a similar thing on a 680, and was only fixed by changing the screen. You could try cleaning the touchscreen film with an Isopropyl alcolhol wipe, but I think it's the screen gone bad.
