My Sansa 8GB e280 Screwing up; Care to help ?

It connects to the computer via USB, it charges, but it won't be recognised on the computer; like, I can't transfer songs and etc to it.
Tell me if you need any extra information, but please tell me specifics.
Thankyou =]
By The way, the last thing I did with it is.
I connected it with a USB-to-Wall Charger converter which was damaged, which needed a wall charger converter.
It blew and broke the wall converter;
Do you think that it may be the reason why it's stuffing up ??
Thanks again =]

 

I guess that makes sense, but it's been working before that. So if I was to leave it charging all night, then in the morning tried to reconnect it, it would work ?

P.S. Is this in the correct section? Sorry if not.

 

Thanks =]
You're cool Loonylion.
You always seem to help with my technical difficulties. Yay =]

EDIT: More complications.
it says that the battery is full.
Now I'm really confused.
:s I think I'll try what you said Loony, then if it doesn't work I'll probably contact the Sandisk company.

2nd EDIT: I changed the battery, to an older, undercharged one. I also used a different cord, that didn't work.

3rd EDIT: I asked my friend who used to work for Sandisk, he said to let the battery drain completely then fully recharge it.
NOW I'm confused.

One of the hubs has a USB mouse, the other has a USB Keyboard. I've tried in all my four ports but still no luck. I'll put my keyboard with my mouse. maybe that'll work.
[I tried it] Still, nothing.
I think what I've done is I've gone and fried the connection port in the mp3 player.
Maybe.

EDIT: Oh and just so you know;
The MP3 player charges with the USB connector to the computer;
I have to connect the MP3 to the computer to charge. =]

 

The whole MP3 player almost dead?
Oh hell no. please tell me otherwise.
Oh and I switched the Mouse/Keyboard Hub with the MP3 player's hub. still nothing.

Now playing: Linkin Park - And One

I've only had it for a couple of months.
Although it was a refurb bought off ebay.
Oh crap.
Is there anyway I can at least try to preserve it's life?

 

I tried it on two other computers, all it does is charge.
I reckon what I'm gonna do is, use all the battery up, then charge it when it's finished, and see if it works then.
If not, well then I'll contact the seller and ask for a refund. I think there's a warranty.
And if he says no, I'll take it to Sandisk.
Thanks Loony.

Nah it was a Sandisk refurb.
I know because it had the "REFURB" sticker-thingy's on the back
=]

 

True that.

 

Really?
Cool.
Thanks Winter =]

 

Hey.
Bumping this because I need help (again)
I'm not really sure how to contact Sandisk.
Like, where do I email or whatever.
Could someone (preferably Winterreise, he has personal experience) please help me out here?
