Laptop dead CPU?

I am trying to fix someones Laptop, a Toshiba Satellite L655 that is not turning on. The person who gave this to me said that they almost never turn the laptop off for months at a time and it is pretty much always plugged in/charging and they finally went to shut it off and the next time they tried turning it on it did not start up. When the charging cable is plugged in a white light on the front of the laptop turns on showing it is still receiving power however still does not start up. I tried taking out the battery/unplugging it from the charger and holding the power button for 30 seconds and tried turning it on again and no luck, I've tried this multiple times. I also tried reseating the RAM and still nothing. Is it safe to say that the CPU may be dead? Does anyone have any other suggestions I could try?

dead on/off switch? Pretty common for the flattened "cable" to snap over time.

It doesn't make any sense for their CPU to die from then turning it off. If the CPU had died it would have turned off during use.

Any ideas what it could be then?

You gonna have to open it up and take a flat head screwdriver to jumper start the motherboard where the power cable is. 

There is no enemy. The foe on the battlefield is merely the manifestation of that which we must overcome. The doubt, and fear, and despair. Every battle is fought within. Conquer the battlefield that lies inside you, and the enemy disappears like the illusion it is.
