HP laptop cannot boot up or charge battery after battery went flat for 12 hours

Try removing the battery and power plug. Then hold the start button down for about 5 seconds. Then plug the laptop back in see if it boots up. If so then power down the laptop and reconnect the battery. See if it will charge then.
 
Is their a charge light on the laptop? if not have you checked the charger it may be just the fuse but if you can try a differant one and see if it works.
