CF-18 Touchscreen to CF-19 housing

Good afternoon, first I wanted to say thanks for all the good information you guys have on this forum, I've used you a lot but I finally got to the point where I needed to ask a new question

I am working a MK1 CF-19 toughbook with a failed digitizer board. I went through all known troubleshooting steps but could not resolve (the mouse goes crazy, touchscreen loses calibration every reboot, when you touch the screen with the stylus it jumps all over the place).

I'm fairly sure this is a Touchscreen board issue after researching the issue, I have a CF-18 MK3 Touchscreen board from a parts laptop that I installed into the system however it is not working at all (I did test the old unit first, everything was working pre-swap).

My question is - do you have any good suggestions on where to go next? The client is a fire department

One thought I had was to release the old Touchscreen screen from the CF-18 and re-seal it into the CF-19 bezel, I don't know if that will work though. I don't want to frankenstien the CF-18 screen into the CF-19, there seems to be too many physical issues with that.

Thanks for all your suggestions, I will be monitoring!

 

Welcome to the Panasonic Toughbook forum

First could you post your full model number of the 19 and the 18. This will give us a better idea what you have.

 

Thanks for the response. The unit to be repaired is a cf-19cjbc3bm, the unit that is being used for donor parts is a cf-18gjhzxbm .

If you believe this unit to require a new board do you have a proper part number for it (or a service guide you can link me to?)

Thanks again!

 

I did find the part number with google-fu for the Touchscreen board, it's a dfup1605za

 

I looked up your configuration ( Panasonic Mobile Computing Configure Products) and found these details:
Model Number: CF-19CJBC3BM Status: DISCONTINUED MSRP: $4,749

Description: WinXP, Intel Core Duo U2400 1.06GHz (Centrino), 10.4" XGA Touch, 80GB, 512MB, Intel WiFi a/b/g/n, Dual Pass (Upper:WWAN/Lower:GPS), TPM, GPS, Bluetooth, Rubber Backlit Keyboard, No Drive, Sprint EVDO Rev A,
One of the items in Device Manager looking for a driver is probably the Sprint EVDO...
It's very possible that your "jumping mouse syndrome" might have been caused by the gps enabled in bios. If It was me, I'd put the MK1 back together the way you had it and disable gps in bios, and then install your operating system.
An alternate trial would be after getting her all back together again, install Linux Mint 13 lts. I had a Mk1 & Mk2 unit with digitizer that worked great with that operating system. If all is well, then you can put the operating system of your choice on i.e. Windows 7, etc....

 

Did you install the GPS Registry Patch Application

 

Did you try the 19 with the Touchscreen unplugged?

Considering the client and that LIVES may be involved, I would not put anything together without the CORRECT parts. Invest the money and buy the right parts for the 19. Dependability and Reliability are of utmost importance in this situation. Used parts that are not an exact fit is NOT A GOOD CHOICE. Not to mention liability issues if that thing fails while headed to a fire.............

Do it right the first time.....

 

In response to a few of these questions -

Did you install the GPS Registry Patch Application - Yes, already applied

- It's very possible that your "jumping mouse syndrome" might have been caused by the gps enabled in bios. If It was me, I'd put the MK1 back together the way you had it and disable gps in bios, and then install your operating system. - The GPS has been disabled in the BIOS, that was one of the first things that I tried, unfortunately that didn't work correctly

Did you try the 19 with the digitizer unplugged? - I have not, the application is touch based so we need to have a windows based OS with the digitizer working properly. I share your concern on the use and it won't go out the door without functioning properly, trust me

UNCNDL1 - I will create a mint live disk to test the possibility that it is something in the OS, but I have my doubts on it. Current OS is XP SP3 with the proper bios and driver patches installed

 

To follow up - I booted the unit with a mint linux live stick, the issue persists (although I really like mint, I've never used the distro, good recommendation!).

This continues to appear to be a hardware layer issue, any recommendations moving forward? The client will allow us to replace parts but if I could have a rough estimate of what needs to be replaced it will smooth the process.

Thanks again everyone, I'll be monitoring all day

 

Is this a digitizer or touchscreen? They are very different pieces of hardware. Digitizer REQUIRES a stylus. Touchscreen will work with your fingertip.

By the cf19 model number, its a TOUCHSCREEN not a digitizer. Try reinstalling the drivers for the mouse/touchscreen. Uninstall any DIGITIZER drivers.

 

Ok this is getting a little confusing...touchscreen...Digitizer ?? So going by the models you gave us both are touchscreens and not Digitizer screens so I am going back and fix the posts that say Digitizer (screen and board) and replace it with Touchscreen. This way everyone will understand what you have including me.

 

once in a while my over attention to details pays off..

 

This is getting me wondering if the GPS patch did not take. I know there is a certain way to install it and if not done right will not work. I think you have to disable the GPS in the bios first before you install the patch ?? or it will not work ??

 

Here are a couple things to try

Set the BIOS to default.
Then disable the GPS In the bios.
Try to run the GPS patch again

I guess it's a touchscreen then guys, it is finger capacitive. I apologize for all confusion on my part, let me do some more research. Thanks again for helping this old dog learning new tricks, I've been doing IT work for 15 years and I've never quite ran into anything like the toughbook

 

It's not a problem, these are 2 different dogs and we did not want you chasing the wrong drivers.

Where I work we have 4 CF-19's mounted to forklifts and when they do go on the blink the IT guys send them away to get fixed...it seams they only know how to fix Dells...very sad. Toughbooks are not that bad to work on once you are around them enough.
