820-2530 no chime no display but turns on.
First post... Like the title says, 820-2530-A, charges battery, shows power and charge leds, turns on with battery or charger alone, fan spins normally for the first few minutes then slowly speeds up to max rpm, cpu warms, video warms...however no chime, hence no display.
