brutal shutdown and feeling of high heat on Probook 6540b

[ Edited ]

Hi all


I am working in a repair center an I am experiencing an issue I have never seen before.

System info :

Probook 6540b P/N WD685EA#AB6  I5-430M 15.6 2GB/320 PC CORE I5-430M 15.6 HD LED AG

First the system entered the repair center for an issue making the system powered-on but with no vidéo and with cpu-fan turning at high speed.


A system board have been replaced, since this time the video signal was recovered but the system still continue to spin the cpu fan at high speed and shut down. The thermal grease has been correctly applyed for précision and at each time. So the system board has been replaced again but with the cpu too. ->same problem occured. Then the system board has been replaced a last time->same problem occurs.


I have noticed that a chip near the cpu genarate a very high heat and seems to be the graphic integrated card. I dont't understand this because of the fact that HP did not equiped this chip with dissipator and that this is the third one that I have changed.


Could someone help me please ??
