when turn on its appear on the screen FAN ERROR then a few sec..automatically turn off

Hi @hukimoko, how long has you been using this computer? when you on, do you hear any fan sound?

  1. some possible problems, fan bearing has worn out, oiling helps, but issues will surface again, perhaps to look for replacement parts in ebay or aliexpress.
  2. check for any dust in the fan blades as it might obstruct the fan movement, causing low RPM values.
  3. on rare cases, is the rpm sensor on the mainboard is having issues. the system has been designed to shut the computer down when there is a fan error during POST, preventing damage to your laptop.

Possibly dust in Fan as after blowing it worked.
