Hello everybody, I owns a XPS L501X.
Upfront:  Linux and Graphics Adaptors are unknown to me, so what I write next might be useless. I cannot judge it.

machine: XPS L501X  
sysversion: A04

from lspci I got:

lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA controller])
02:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0df1] (rev a1) (prog-if 00 [VGA controller])

trying with the 'test_off' i got no positive results. However I fetch a copy of acpi_call from https://github.com/peberlein/acpi_call 
and running the "m11xr2.sh" script throw some positive results. 

then, a new lspci: 

lspci -vnnn | perl -lne 'print if /^\d+\:.+(\[\S+\:\S+\])/' | grep VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 18) (prog-if 00 [VGA controller])
02:00.0 VGA compatible controller [0300]: nVidia Corporation Device [10de:0df1] (rev ff) (prog-if ff)

Note how the nVidia line changed. It is not longer labeled as 'VGA controller' so I suppose it is off. 

On the same way, the 'present rate' of battery consumption (cat /proc/acpi/battery/BAT0/stat) dropped from 2500mW to 2000mW.

Finally I follow the steps on [#3 Disable the nvidia gaphics card to increase battery life] adapted to my card

http://robbyx.net/blog/?p=190

so that it is switched off on each system logon. I attach the nvdown that worked for me (the one in the article is for Asus Laptop).


Sincerelly I dont know If I really switched off the nVidia card or it is just an illusion. Hope anybody can help me to confirm that
