Hello
I plugged my F40 into my usb cable overnight last night. When I plugged it in, the F40 was as 67% charge and was turned off. When I unhooked it from the usb cable this morning and tried to turn it on to check to make sure it was charged, it wouldn't turn on. It required switching the battery off and then on manually to boot the F40. Once booted, it was at 100% charge. So it worked, but I had a heart-pounding moment when I thought I had perhaps fried the battery or something.
Should this be happening? Is there some trick to usb charging that I'm not following? I like the idea of usb charging, but don't want to have to reset the time/date every time.
Thanks!
Nikolaus
