hi

i have a laptop here that its fan run at full speed from startup
and in HWmonitor is tz00 sensor with 86°C whitout any change

but cpu temperature is about 35-40°C

i change cpu and reprogram bios but not change in fan speed

There are 3 main possible reasons for it:
-PCH
-ME
-thermal sensor

So, first of all you should do - programm bios with CLEAR ME-region by programmer. Also, do this need to reconnect RTC battery.

write down the correct name of notebook from bottom case like K42Jx-Sxxxxx

Also you should read this article where you can find basic knowledges what is need to do.

MB Ver is k42ja

and correct name from bottom case is k42jp-vx77d


i read bios from similar board(k42jp-vx092)

no more help ؟؟؟

You need flash the BIOS with CLEAR ME, not from another mobo!
Read message from RsM again.

oh sorry

iv not used ME-Region yet
i think he means program bios whit similar file

now i should program bios whit hm55 ME-Region bin file(937kb)?

flash it
