Fujitsu Q550 problems with digitizer in some pixel lines

[nebu]

hi,


ive a problem with my Q. If i write with the stylus in windows journal, there are 2 or 3 pixel lines which cant be "overwritten" in a certain angle.

the problem appears only if the tablet is in battery mode and additional to the pen my hand lies on the display.

I use windows 8CP, but with WIN7 there was the same problem. A friend bought the same Q550 in the same shop at the same time and he has the same problem!

ive made a video and hope you see the problem:

Q550 problem - YouTube


my thought is that there are some inductive disturbances (maybe some spools on the circuit board and if i change any current because of the pluged in charger (or my hand), the magnetic field changes)

does anyone else have this issue?

nobody has this problem?

if yes, ill replace the display..

I have similar issues with one note where the pen refuses to write in some locations. It seems random though and I have not found any method to the madness.

my q is in repair. it gets a new display and a new on/off switch (its very hard to use the switch when the tablet is in the original folio case)

i will give a feedback if the problem still there

a fujitsu support shop changes the display now. With the 1st new display, the fingerinput doesnt work (only pen input). Ive tried a Windows 8 repair, but already cant control the setup with my fingers. So they change the display a second time... same issue! Still no finger input possible. And the main bug in Windows Journal (or other progs) with the pixel lines which cant be overwritten is still there. so i guess ALL Q550 have this issue!?!
Now ive two options.. 1) change back to the old display and live with the problem or 2) try to get a complete new Q550 (but i still dont know if this pixelline problem have all Qs)...

[nebu]

can please anyone give a feedback due to my problem? I guess here are more Q550 users...

summary:

- some pixellines, specifically the line with a distance of 74mm from the top of the display, is buggy and cant be can not be overwritten in a certain angle
- problem appears only in battery mode and when the hand rests on the screen



it would be nice if some q550 users give a short report (problem also exists or not)

Hi,

I have a similar problem, probably related. In my Q550 (Atom Z670, 30 GB SSD, 2 GB RAM) the digitizer have some problems in a 8x8mm grid. The problem is barely visible when I write, but if I try to fill an area the ink make a small "jump" creating a small grid.



In the picture, I highlighed in green the "grid". The 74mm line is one of the point where the problems occurs. The problems is present with battery or power cable connected.
