Good night indeed.

It will take our board enable specialists a while to create a board
enable for you, so don't expect anything tomorrow. If you know where to
find a service manual for your laptop or if you have any high-resolution
photos of your mainboard, creating that board enable will be easier for
us. We need to find out which SuperIO or EC (Embedded Controller) your
board is using. superiotool unfortunately didn't find anything.

In general, we recommend people to use the vendor flashing tools on
laptops because the risk is much higher than on desktops where you can
recover quite easily.
