my notebook is acer 5755g and cpu i5 2430m
my laptops battery life is not problem. i can use bumblebee for optimus or i can disable second graphic card from bios.
i tried all kernels... always result:
dmesg |grep ASPM
[ 0.000000] PCIe ASPM is forcibly enabled
[ 0.243654] ACPI FADT declares the system doesn't support PCIe ASPM, so disable it
[ 0.406719] ACPI _OSC control for PCIe not granted, disabling ASPM
is there anyway activate aspm on this system
