I believe this is a common problem but I haven’t found a working answer yet. My Fuze 4GB has been working fine for the last 3 weeks since I bought it, and this is the first time I’ve needed to charge it as it’s currently <20% battery life. Plugging it into my computer (tried all the USB ports, front and back) and it shows “Charging” for about a minute then goes back to “Connected”. Tried using a USB AC adapter and that didn’t seem to work either. I even formatted it once, but no luck.
Other than this charging problem, it works fine. Turns on and off with no freezing, syncing works fine, menu runs smoothly, and all that. Should I try another computer or is there another fix?
