Dell m6300 wont power on


Nov 24, 2012
I have a dell M6300, It has been a work horse for years, Several days ago it powered off. When I try to re-start I get a green power light, a flash of a hard drive light and a battery charging light. Instantly the Hard drive light goes out, I get a tick from my CD and then nothing. The power light stays on and the battery light does the slow green blink. I cant get into the system bios or anything.
I've pulled various installed items, hard drive, CD nothing makes a difference. I've done the ram dance, I've pulled the graphics card and replaced it. I've tried booting up without the battery. I need a direction.
