I generally do not work with PC's as I am a systems person but have a question. I have a M6700 DELL laptop and this thing up until a week ago was awesome. Now when I cut it on the fans kick on and after a few seconds it just shuts off. I get no display but did notice the battery LED light was orange. I replaced the battery with a DELL battery and also the power cord with a Dll. It does the exact samething except this time instead of the light being orange its now white along with the other lights just as the hard drive. Could this be the motherboard. I left it connected so that the battery could charge but I doubt that's the issue. I took it a step further and took the battery out. I tried to power on the laptop without the battery just the power cord and the samething occurs. Does this sound like a motherboard issue? I hope not please help.
