Inspiron 1525 Plugged in, not charging battery?

I have read the posts and tried same remedy, but since battery is completely dead, won't let me turn on while unplugged. I have tried 2 different AC adapters. I don't want to buy a battery and find out that is not the problem. On battery info, says battery is operating correctly whatever that means! Tried taking it out, powering down, everything suggested! HELP!! Any ideas would be appreciated. :-)
