Dear ladies & gentlemen, I like to adapt fan control in the bios, but it is not possible to get into by using F2 or the advanced start setting in Windows 11, which produces after a restart the stop code 0x50. How to proceed? I have the BIOS revision AB525\_V00.01\_0002.

Try spamming F7.

A Google search will give you the information.

Found the solution: using an external USB-keyboard and pressing F2 during power up works fine.

In my case, also with Corebook X 7430U (although really with a 5500U), after trying different keys, the one that works for me is the “ESC” one.

On some devices the timing for entering UEFI can be really picky, especially with fast boot enabled. Using the advanced startup option from Windows has saved me a lot of frustration when the usual key combinations wouldn’t work.
