Power out gateway mx6124

[deseraligears]

I recently had a problem with a gateway mx6124 i replaced the power cord as it was bad with a new one when I plug the new one into lap top the red light flashes and than stops
if I take the battery out and try nothing . is it the swithch? Is there a way to test to see why it won't power up when plug into source? Thanks

"I replaced the power cord as it was bad with a new one"... Did the old AC adapter do the same thing, red light flashes and stops?
