[QUOTE="romeyn, post: 1752330, member: 183109"] UPDATE: Through trial and error I determined that there was something inherently faulty about the replacement display I received. When it was present, the LCD temperature sensor read HOT and the computer was dog slow with fans running. If I put the old, cracked display back on, everything was fine. I transplanted the sensor from the old display to the new one with the same result--slow when new display present. Diagnosis: faulty display. The vendor has replaced it. Last night I installed it. LCD sensor reads normal and computer is blazing fast. Although an "Ambient Temperature" sensor reads about 249 degrees C!! And yet the fans are behaving normally. I have looked and looked and can't find a diagram of where these sensors are located. Any advice on that? [/QUOTE]
