Walkman NWZ-W252 wont charge anymore

[usernameless]

I cant charge my walkman anymore. When I plug it into my computer nothing happens like i never plugged it in in the first place. If I start the content transfer it asks me to connect my device. Never had any problems before. My battery went out the other day and i connected it to my comp and this is the first time this happened. I tried to reset already. Any advices???
