Clevo n240lu bios too big

[eukal]

Hello i have an Clevo N240lu from a friend that doesn't start anymore. It power on but not display black screen and after few seconds fan spin at full speed.
I have try to replace ram on both slots but nothing so i think the bios is possibly corrupted.
I have backup the bios and download a new one on the clevo website but the size is too big.
Could you help me to have the good size bios ?
Thanks.

Your bios backup is 1MB should be 8MB, so either you've dumped the wrong chip, or the chip is not read properly. Try again. Post SPI chip markings.

Hello, My bad, wrong ch341a software . Here is a good backup and i have succes to flash the clevo website bios.

Now the laptop stay on but always with fan at full speed and no picture. All power supply is up and running. Bios pin have 1.8v except pin 4 abd 7 so i thin no bios problem am i right ?

I doesn't find any other n240lu bios file, only the file of clevo website, just other on vinafix but i'm not no registered.

And no shortcut on the board.

In the zip file from clevo there are an ec file, i think i doesn't need them but maybee i'm wrong ? Peraphs with bios update i have to update this ec file ? If yes is this possible with ch341a ?

Thanks for any help.
