CF-30 touchscreen needs hard push by finger or pen !!!!

hello there
just bought 2nd hand cf-30k tough book ,,
windows 7 x64 installed
bios ver 3.xxx
all drivers seems installed nothing missed
but >>>
when i try to use my finger to touch the screen it seems i need to push too hard o n the screen
also with pen
for sure its not normal !!!
i tried to cali it by fju calib
but the problem still exist
i took another cf-30k ...but the same problem !!!
can anyone tell me what can i do ?
thanks

 

Welcome to the Panasonic Toughbook forum

Could you post your full model number CF-30??????? . This will give us a better idea what you have for a 30 .

 

thanks for ur response ..................the model number is
cf-30kcp1q2b also i triyied with another one c-30kcpal2m>>>>>>>>>>>same problem
i soent all the day trying to solve this problem ..but nothing

Use the Windows Tablet calibration in the control panel,not the Panasonic one. The Mk3 was the best of the bunch and should be easy to use,please state the bios hours of both units.

 

The hours can be found in the BIOS screen , first screen. Press F2 on startup. The hours will be listed at the bottom. I had a 30 just like yours with about 15,000 hours and I had to replace the touch screen on it which fixed the problem. One thing I do find the 30 works better with the stylus than your finger.

 

These were designed for gloves but I find that tapping with the fingernail....palm facing your face is fine.
No offense please but are you used to cell/smart phones and expecting the same response....not happening friend. safn1949 nailed it. Thanks Kerry....

 

To OP, Are you the original owner of this machine? I ask coz If the machine exposed to direct sunlight for certain period of time. The touchscreen panel tend to expand. The effect is when you touch panel, it tends to woble/move( I don't know if it is the right word, Lol..) that is why you need to touch a bit harder.

 

i did ..control panel calib used many times but nothing new ...today i brought 10 cf-30k family .....it seems they all have same problem idk y ....but most of them working hours r above > 11000 hours........bios v3

 

ya thats right ...stylus work better than fingers idk y ....

 

before days i broght cf-c1 multi touch ...every things r ok no need to push too hard on the screen !!! also ibm x201t multitouch too ,,dell xfr n so on ...im still trying to find someone who solved this problem ...is it in bios with win 7 x64 sp2 or not

 

i tried to update hid drivers in device manager ...it seems something in drivers i think the problem is still exist but not need to push more harder than before ...do u think its drivers or bios problem ?

 

This is one of the problems when using 64bit instead of the 32bit that Panasonic uses.
You can not get the proper drivers because Panasonic did not make them.
Your only choice is the generic 64bit driver on the Fujitsu site.

You can experiment with the Panasonic official 64bit driver for a CF31 mk1.

It is NOT a BIOS problem.

 

a couple of points ...
while the touch screen on my '30 is not as *sensitive* as the more modern devices , it works with a pressure of about twice as much as my phone .
this pressure is slightly greater than that required by my '31 .
but still , the pressure required by the '31 and the '30 are not what i would call excessive .

a part of the problem here is one of "subjective measurement" .
no two people *feel* pressure in exactly the same way ...
that is why gauges and torque wrenches were invented .
if the OP were to have said that he had to push so hard that he was afraid of breaking the screen then i would say that there is a problem .

another problem is as shawn mentioned : drivers different than what panasonic says work and are proven to work properly .
this is compounded by the fact that a 64 bit OS was installed versus the factory original 32 bit .
(off the top of my head i do not know if the panasonic 32 bit drivers will install on a 64 bit OS ... mismatch flagging) .

there are too many variables to accurately point a finger at one item and say that is the problem .
changing the touch screen is hard to do and expensive ... it would be better to get another HDD and load W7 32 bit , then try the factory drivers .

which brings me to another point ; didn't these machines come from the factory with a 32 bit OS installed ?
a 64 bit OS was not an option ?

 

The CF30 came with 32bit only.
Touchscreen panels are not that expensive anymore. $40.00 from China

Difficulty depends on your skill level.

 

ya my friend i replaced the hdd from one to another cf-30k families ..but it seems the problem still exist !!! i have now 10 units same problem !! im not sure if its come from factory with this issue (i call it issue ) ......

 

i did it ....mk1 cf-31 x64 drivers for touchscreen but the problem still exist !!

 

ya but do u think the problem in screen touch >? i got 10 units now im still trying now one by one replaceing same hdd from one to another but the problem still !!!
also 32bit drivers work very well with x64 win7 !! idk y

 

Thank you for the driver information.

One test is to run a version of Linux from a CD and see how it works.
You can also get a factory recovery disk and load win7 32 bit from it. The recovery image will have all of the correct drivers already installed.
It is starting to sound more like this is just a difference in how the touchscreen on a Toughbook feels.
It'ds doubtful that you have 10 bad touchscreens.
The touch on my cell phone is very responsive compared to any toughbook.

 

What I would do first is get yourself the factory restore disk . This will restore the 30K back to the way it was when it left the Panasonic factory with the correct 32bit drivers.

 

Is this the first Toughbook you have owned. The newer touchscreens work much better than ones from 5 years ago.

Think me and Shawn are thinking the same thing

 

shawn i feel crazy lol ...i tiried linux backtrack the touch work but it seems need to calibrate but still need hard kick )
also i noted in win 7 x64 if i use my finger nail or styles it will work ok ,,so soft so easy but finger mm no need hard push ...
i tried to download bundle drivers for this station took 150mb but idk how download win 7 image recovery cuz it has coa vista ....
now i uploaded a pic for what i have in my room ,,,these laps make me crazy

 

Hah! LOL Looks like my couch before I got the roll-around book case. That just holds CF-19, CF-52, CF-30 and 31. CF-29 are EVERYWHERE else.

Larry used the word "subjective". My experience with ANY touchscreen started with a MK3 CF-29HTM50BM. So...several years later when I got a Smartphone it was way too sensitive at first.

New replacement touch panels are slightly more sensitive than a old one. Nothing fancy it's just that the connections are clean.

My biggest issue is I have to take a glove off to use the Samsung Smartphone.....many someone elses had this problem as I see many gloves advertised with "touchscreen sensitive". Doesn't matter if they keep hands warm as long as you can use the touch.

I swipe mine with my nose. rofl (to answer phone)

 

Same here Jeff . At least our fingers stay warm.

do you proffer your cell phone with undue enthusiasm when others ask to borrow it ?


as shawn mentioned ...
it is doubtful that you could have 10 bad/marginal touch screens :
i don't see 10 interface boards being bad
the software and associated soft/firmware on 10 machines can't be bad
unless all the machines were sold because they have the touchscreen problem caused by one or more of the above reasons .
someone could have bough those machines and discovered that all had the same symptom ... they in turn sold them to you .

there should be a way to measure the force required to operate the screen .
one way might be to use a stylus held upright on the screen (laid flat) and stack coins on the stylus until the screen "sees" the point closure .
measure the total weight of the coins and post it .
you may want to run several tests to get an average weight .
a couple of us can measure our '30 screens in the same manner ... then we will have a much better idea of what is real .

measure several of the screens ... to compare pressures and see if any are way out of range .

 

sir u cant understand what u r talking about ??? a way to measure the force???

 

to eliminate "subjective measurements" ... the pressure needed to operate the touch screen has to be measured in some way that eliminates "guessing" what is required .

for example , i can lift 200 pounds and do not think it is much .
another person might say that 200 pounds is too much for them to lift .

we (or at least myself) cannot say that what you say is "too much" really is ...
you need to provide an accurate measurement that removes the "human element" as much as possible .
stacking coins on an upright stylus is a bit tricky but can be done ...
a tentilometer could be used but most people do not have one laying around .

@ the others here ...
i looked briefly but could not find the actuation specifications/range of those touch screens .
does anyone have the specs ?

 

Operating Force
0.05~0.49 N (5 ~ 50gF) Measured with
a Silicon Measurement Rod R 8
(Round type 8mm) Silicon Rubber

from this
http://www.fujitsu.com/downloads/MICRO/fcai/touchpanels/4_wire_standard_ds_rohs.pdf

 

Figures that Shawn would find it. Good show.

heh! Now explain what it means. (kidding)

 

cooolll ...
5-50 grams with an 8mm soft rod
the silicone end emulates the end of an index finger .
the range is 10:1 ?! ... i bet that the lower number is for the point of the stock stylus .
i would imagine that less pressure is required at the middle than the edges .

aren't the screens on the cell phones and such pretty much capacitive types ?
those technically require no "pressure" to work ... they rely on on the actuation device (stylus) to provide a given minimum amount of conductive/partially conductive surface area to work .

@ OP :
the touch screens on the '30 are a "resistive cross point contact" (google search for more information and pictures) type ...
basically they are two sheets of glass with a vapor deposited resistive array .
the glass sheets have a very small gap between them .
the stylus bows the glass and they come in contact with each other in a small area at the stylus .
because this is a mechanical device it is subject to the effect of "distributed force" .
due to manufacturing tolerances , there will be a variance in the required actuation pressure between different touchscreens .

until *real data* is gathered by the OP , i cannot see where further diagnoses is possible .
