If you have ideas, let us know. I had the vague feeling, that the voltage recovered after use. Before turning it off it showed less capacity than what I saw after turning it on again. And that it stayed at a higher level it had before turning off (I vague remember seeing something about 40% before off and 55% after turning on again.) -- Holger Lembke Keep your Mailbox SPAM free: +49-531-334676 Disruptor OL http://hlembke.de/dol/Received on 2003-01-19 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
