Re: Toshiba L510 power problem

I think you have 2 issues. First one is the battery controller or some mosfet near power on, and the other is turning off after 5 min. Did you measure the temp before it shuts down?

Check the megathread on this issue.

Primarily, it is caused by a bad capacitor made by 'NEC-TOKIN'

Hope this helps you!

Is the CPU and GPU getting enough cooling?

You might have a bad joint somewhere, which could be heating up and disconnecting, making your computer shut down.

Hm, does the power jack plug get hot? Mine (an L645D) started to give error codes, and the battery didn't charge all the way - the power jack was very hot, which told me that there is a bad connection. The wires that are soldered to the power jack were broken, and had arced and they were discolored. Re soldered the wires, and all is good

But I don't know if this could be your problem or not.
