charger light blinking orange and computer won't start up

My charger on my computer broke a couple days ago so I ordered a new one. While waiting for the battery to come in the mail, the battery on my computer went dead. Now I have the new charger and when I plug it into the computer it blinks orange but never gets a solid orange. Also, the computer will not fire up. Years ago I drained my battery dead and it took a little while charging before it fired back up. I'm hoping its the same problem but it has been over a hour now and still nothing. Anyone have any advise? Thanks
