Auto shutdown - HP Pavilion DV6700T Notebook PC

P0685 DODGE - Auto Shutdown Relay Control Circuit Failure
Possible causes - Faulty Engine Control Module (ECM) power relay
- ECM power relay harness is open or shorted
- ECM power relay circuit poor electrical connection
- Faulty (ECM
Possible symptoms:
Engine Light ON (or Service Engine Soon Warning Light) P0685 Dodge Description: Short or open in Auto Shutdown (ASD) relay circuit, this relay is under the hood in the relay center.

I don't think there is a way of turning off the auto timed shutdown. You can cover the solar cells, which will probably cause it to shutdown earlier.

Good luck,

On mine, until an electrical storm, was controlled through my computer via USB. Now, it shuts down in 5 seconds. I'm sure it's the thermistors, but I don't have time. Also, check for timing circuits.

Restart the Computer and keep tapping the F8 key till you see the advance boot options, You should be tapping the key as soon as you see the manufactures screen. Once you get the advance boot options -> Select the option which says Disable Automatic Startup on System Failure.
Good Luck!!!

Is it possible to repair the controller board some how? Replacement is not an option because I have approx 100 projectors of this model and X16 lying with me, requiring immediate repairs...

There is no switch. The relay gets a signal from the computer. If there is no signal from the crank position sensor the computer will not close the relay. If it runs with the relay bypassed, chances are good that the relay itself is bad.

Check to make sure that the auto shutdown is turned off. This should prevent any further problems.

Auto shutdown relay and fuel pump relay are by the battery under a cover.
