I'm looking for possible solutions or areas to investigate.
When my FR's arrive I was going to investigate this area, but wondered
how easy it would be without a debug board..

Kind of like I used to do with my old Palm III back a decade ago, because if you let the battery wear down then you lost all your data (talk about design flaws... that was an awful one...).

Apparently the touchscreen is getting bumped and keeps waking it up when its trying to sleep.
