I have had a Sonicare toothbrush for the last 3 years. And I love it. Last week it stopped working. I don't know if it is the battery or the charger. I also don't even know how to change the battery if it needs replacing. Does anyone have one or have experienced the same problem with theirs?

I did Google it, and most say to just buy a new one. Which I will do if I can't fix this one.

I miss my Sonicare.  :'(
