Please post all inputs, and all outputs of that sequence of commands once they are finished being run.
If that is not successful I would recommenced doing the following:
Power down the laptop and remove the battery and power plug. Let the laptop sit without power for a few minutes. Then, hold down the power button for approximately 30 seconds. Pressing the power button will help drain all left over power from the unit’s motherboard.
Then reattach the AC power (no battery), and restart. Boot into your bios, then reset the bios to the factory defaults, save the default settings. See if it will boot correctly with the factory default settings. If not, you may have to change a few settings in the BIOS (such as secure boot, fastboot, AHCI) to get Garuda to boot correctly. After rebooting your adapter may be working properly.
