Re: [coreboot] Lenovo X200 running Coreboot drains 3-4W more power than with Vendor BIOS

Hey,

I guess the vendor bios activate pci clock power save and similiar
options. Some are supported by coreboot, but not activated by default.
I can only guess, but the native vga init might also miss some power
management features.

best,
