Why won't my sansa fuze come on?

Answer 1

There are a number of reasons, but one thing that especially worked for me was holding the power button up for at least 10-15 seconds; it's like holding it to turn it off, but you just hold it longer. The reason for this is that the Sansa Fuze has a nasty habit of freezing, and when it does that when the screen is dark, it looks like it's off. All you need to do is force a shut-down, then simply turn it on. Another thing you can do is to simply plug it in to a power source.
