I'm using an asus U43Jc "bamboo"

$ sudo dmidecode -s system-product-name
U43Jc
$ sudo dmidecode -s system-version
1.0
$ 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])
01:00.0 VGA compatible controller [0300]: nVidia Corporation GT218 [GeForce 310M] [10de:0a70] (rev a2) (prog-if 00 [VGA controller])

and here is the DSDT.dsl:

Using the method described here: http://linux-hybrid-graphics.blogspot.com/2010/07/using-acpicall-module-to-switch-onoff.html
gives the following result:
Trying \_SB.PCI0.RP00.VGA._PS3: works!

however when I try:

echo '\_SB.PCI0.RP00.VGA._PS3' > /proc/acpi/call

nothing happens.

Someone seems to have had succes however using the method described
here:
