Not to mention that the issue with your laptop is a common HP/Compaq problem and most good techs or do it yourselfer's know the laptop is shutting down because it thinks it's overheating(most times) or it actually is overheating (rare). The steps to correct either are quick and easy. This issue goes all the way back to the PII & PIII's. Not exactly the brightest porchlights on the street, are they?
