Then Vista is not a factor. I own the rx3115 and let me check if it's still working. Yup, it's ok. I have the ROM date of 1/25/05 version 1.01.11.11ENG too.
Try pdaparts.com and see if they will fix it.
After weeks of struggling to sync my old iPaq with my new PC's Vista Home Premium operating system, I finally succeeded only to find that the touch screen is "dead." It worked fine before, although I'm not sure there's a causal relationship. I've tried both "soft" and "hard" resets to no avail. Does anyone know how to restore the touchscreen functionality?
