Mac book white 13 inches late 2006 4g ram, 500G HD WD brand new, OS 10.7.4, new battery. Some time shut down suddently. The charge indicator in the finder does not work properly. When the battery is full, I can read no battery, if i unplug it is the same. If I reset SMC some time the computer reboot with fan full throttle, some time indicator work well for few time. Now I am unpluged and I can read a X on the indicator like if I dont have battery. When I unplug the screen did not deem.

Bring your machine in for servicing. Even if you're battery were completely depleted, your Mac would still recognize it as being there. Either a component of the battery is damaged, or an internal sensor on your machine is broken. This is a hardware problem and no futher troubleshooting steps can be taken to solve your issue.
