Notes file storage on AspireOne in Linpus

Does anyone know where data for the Notes reminder program is stored on the Aspire One (model AOA110) with Linpus? I want to recover the file information since my Acer won't reboot and just shows a blank screen. I can boot up in Ubuntu with a USB flash drive and can see file listings for Linpus, so I assume the Notes are stored in one of these files, but which one, and how to access them? All my other data files are intact on the 16GB memory card I added to the expansion slot, but not the Notes files. Thanks!
