Why does my white MB A1342 keeps turning off?

Hi,

My sons white A1342 keeps shutting down even if the battery is fine and the power cord is connected. It seems more like a short because it turns off in more or less a heartbeat (sometimes the turn off screen comes up) . If I start up with option+D for hard ware test it does keeps going.

I have tested with other RAM, another hard drive, I've made a reset of PRAM and SMC but nothing works..

The battery is suppose to be in fine shape and no hardware errors are reported.

Are there any known circuit failures that can short it? Any other known problems that could make this happen?

Best regards

Jesper

Have you ever spilled liquid on the machine?
