Not turning on or charging

Haven’t been on the forum in awhile and I know this topic has probably been mentioned before but I’m having issues with my OP. Went to turn it on this morning after a month or so on the desk and no power, won’t turn on, leds so do anything when charging. Only thing I hear is a slight crackle from the speaker when plugging in the USB cable or turning power switch on.
Is my OP dead?

leave it charging for a couple hours to a day or so. should kick back eventually if everything is okay.
