One of my co-workers brought me her laptop, and said it wasn't working anymore. When you plug in the charger, none of the LED lights come on and it will not power up. I have removed the battery and re-seated it. I have tried wiggling the cord where it plugs into the computer and slowly moving it in and out to find that "sweet spot". Nothing has worked. I am thinking it has to be the charger and/or battery or possibly the a/c adapter where it connects to the motherboard. I did look at the adapter and it doesn't appear to have a broken connection. I do not have another computer with a battery or charger to try out on it. Before I order a battery and charger, is there anything else that could possibly cause this? This is a Gateway, model M-6827, running Windows Vista. Thanks for any help.
