I extracted the hd and then tryied to boot, but I got the same error... I'm going to copy the important data from the disk just in case.
We've reached a dead end, right? Any other idea?
Thanks for your time!

Hi,
Sorry to say, but I think you're right - that's pretty much ruled everything out apart from a fault on the Motherboard.
Best regards,

My Friend:
I have the same problem, with a DV4 2116LA
I have read in Internet that blowing hot air into the cooler outlet (with a hairdryer), will enable the notebook booting.
Since I was lost and needed to boot the computer, and did not have much else to lose, I did try and to my surprise the computer and it worked perfectly.
But the problem persists and everytime i start it should apply hot air. Obviously this resolve the contingency, but the computer loses all sense and practicality.
I understand that the computer during startup, verify that the heat sink is mounted and is able to extract the heat. For some reason that I do not know, this check fails and then the computer will not boot.
Then, why heating it works? Probably because the initial test checks the temperature rate of change, only immediatly after turn on the computer. When heat is applied, the temperature sensor is out of range and then the rate of change of the temperature is zero (is out of range and max) and the boot computer normally.
Would be good that HP do something about this, cause sounds a design latent defect, since a lot of units of this models present the same failure.
I appreciate HP or somebody share the solution if found.
I wish not hear: "you should replace the motherboard", but "unfortunately this model was discontinued last year"...be creative!
Best Regards
