We recommend using the "fan re- detect “option in the BIOS and if the issue persists remove the RTC (Real Time Clock) battery and leave it out for 20 minutes. After this period of time, insert the battery back in and turn the system back on; if it displays POST messages, go into BIOS Setup Utility by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Press <F10> to save the new settings and reboot the system.

Dear Dan, hello.
Thank you for your answer. But I could not find such option in my BIOS unfortunately. There is only "Restore Fan default settings" in the BIOS and it does not help.
Tomorrow I will try to remove RTC battery for a 20 minutes.
