Hp Probook 6560b 90b fan error at start


Jul 25, 2012
(fan needed to be cleaned from inside working now)


Everything was working fine. But for last 3 days this error is showing at almost every start. I tried Air Blower and Pin to clean the fan and the outside area. It didn't worked. Today at office TEMP was at 99C.

I opened the case and notice at start when i power on fan doesn't spin at all (only 30 degree spin than stop when i press power). After booting the OS. It spins at very low speed. After that it spin just okay. But not like before. I updated the BIOS to latest version and felt that it reduced the speed of fan. I am worried what should i do?

PS Error occurred before bios update. After update it reduced the fan speed even more.
