how do i process a warranty claim? My toothbrush came with a promo that extended warranty from 2 yrs to 2 1/2 yrs. My sonicare is dead I have 3 chargers so I tried charging w/the other 2.. The charging indicator light on the toothbrush did not come on. Just for grins I left it on the different charger overnight but it was still dead this morning. I've searched the internet and can't find any info on how to process a warranty.
