Hi Diego,

I also have a brant new Clevo W150HNM, but the Nvidia GPU switch off isn't
working for me using Ubuntu 10.10 and kernel 2.6.35-28-generic 64bit (the
default kernel).

May I ask you which kernel and ubuntu version you are using ?

Moreover, I have stability problems: when the power isn't pluged in, the
wired network card isn't stable, I can see link up/link down message every
ten seconds or so in dmesg.
Do you also have this issue ?

Anyway, thank you for the fix for the suspend problem, I will try it this
evening.
Best regards
Loïc
