Re: XPS L501X - switching nVidia off
I can confirm (after repeating the procedure several times) that there is an
improvement of 200mA on the battery discharging rate (reported by acpi) with
an scatter of 30 or 20 mA.
It would be great to confirm if this is the power consumption of the nvidia
310m.
