Not sure but think this will be of some use.

!1.04 kept crashing on me when I put it on my computer so I retuned to
10.04 till 11.04LTS comes out

Know this does not help but its my view on it.

you may have to go into Settings and adjust the power options.

I'd already adjusted it to never sleep.

Ian, I havent had any trouble with it crashing. Im testing this little Zotac out
for a project and the hardware is good and so far, except not for being able to
quickly move about the OS, Ubuntu is okay.

And Ill check out pm-utils.
