My granddaughter knockedmy nook off table while charging , bought newwcord now no lights have had it plugged in for over 48 hr

Sounds like you may have damaged the charging socket for the Nook Tablet.

Try cleaning it with a toothbrush to ensure there is no dirt of obstruction in it ... put a little isopropyl alcohol on the brush.

Remove the battery and clean the contacts ... check and see if it has any charge in it with a multimeter.

If the battery is charged and it still will not turn on then the device is damaged.
