I bought a Sansa Express 2GB on Ebay because mine finally gave up its ghost after 9 magical years. The new Sansa was still sealed in the injection-molded retail plastic box, so I can’t claim tampering.
When plugged into the USB, the display and dog animates “Charged” not “Charging.” Despite some long charges, it still displays in Windows explorer as “Critically Low” and 0%.
I’ve upgraded the firmware to version 1.01.12 on a 32bit machine. The Sansa Express still will not charge off the included USB.
The next step appears to be looking for a bad battery solder?
Any ideas are appreciated.
