Hi   I also have an older laptop with the W240HU/W250HUQ motherboard BIOS 1.01.06 and KBC/EC 1.00.02: D02A   The fan problem has been an irritation, but more of a practical problem is that I now could not use Android Studio with emulator since I could not activate virtualization in BIOS. So good reason to see if a BIOS update could fix things.   These are no longer found on clevo.com.tw which had ftp sites earlier. I downloaded from here in stead. https://repo.
