I dunno if this can happen, but I'm pretty sure that a press on the reset button is shutting it down properly. So you may do the counter-test by shutting it down whith a needle after your train ride... It's still possible that the battery has a problem. Certainly not due to simple age, as you pointed out, but LiIon-Batteries do not like the cold, for example. I've been told about batteries having lost a major part of the capacity (irreparable) after having spend a frosty night in a car and it's a common problem that cold batteries can not supply the same power than warm ones. > The other thing; does rockbox charge from usb if the battery is > drained beyond startup voltage?

It's planned, but not yet realized (as the startup on charger plug-in is) One possibility is, as you pointed out, to start the unit with rec+play, so the original iriver firmware is started which charges from usb. lImbus Received on 2006-03-07 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
