Windows going to a black screen when the Intel graphics driver loads means the the VBT (video BIOS tables) data is missing or invalid. Does your board have a data.vbt file, or are you including an external vbt.bin? Which display init type are you using? run 'make savedefconfig' and past the resulting defconfig file - the full config is unnecessary and too long to parse.
For the battery, that comes from ACPI, and is usually included with the ec code. Nothing you should have to do there. Could be the result of an ACPI parsing issue, or something else. Would need to inspect your ACPI tables cheers, Matt On Thu, Sep 3, 2026 at 7:43 PM Logan Proctor <[email protected]> wrote: > Hello! Is this the right place?? I don't know how this works..
