Please specify if you own the Sandisk DAP 1gb or the Sandisk Sansa 1gb, which has an SD card expansion slot. I own the Sansa, which i reviewed (http://www.epinions.com/content_186478988932)and have had no problems with it. You should try getting brand new batteries (not rechargeable ones) and see if they power up with those.
Was wondering if anyone has had a problem with one of these players. I just have no power to it even after changing the battery.
