Kernel power event 41, task 63

In the past few months, my Toshiba Satellite L675-S7048, began to reboot on its own. No BSOD at all. After looking at a few postings on the subject and looking at my machine, I determined that it was a kernel power event. I turned on logging, waited for another crash and have collected the log files from the Seven Forum Diagnostic Tool. Any help would be greatly appreciated.
