After the responses here I reset the fans to default. The wife and used last night to watch video and mp3 streams. Checked the temps occasionally were between 45-53C. Woke this morning carried downstairs was still working great. Then all the sudden screen went dark cap lock & num lock lit up fan spining full speed. pulled the battery and power cord. Pluging in power cord only it turns dark amber almost red no power up. Battery only cap & num lock light up fan spins no boing. tried resetting pmu with shift-ctrl-option-power no change. Guessing the logicboard has gave up the ghost in the machine.
