I keep my sony prs 505 in suspend mode for several weeks, when i started to use it again, got the warning "low battery", despite that I still can read. later I charged it for one or two hours, I can see 'charging' on the screen, then I closed the book even before it was fully charged. today when I open it, the screen has the main menu on, but not responsive, even I press the 'reset' button, during charging, i can the see the red light on, but nothing in the screen except the main menu, btw, the battery indicator displays no bar. any idea how to restart this? thanks.
