The power button does suspend my computer (I see text, then a black
screen), but it comes back to graphical mode almost immediately (1 or 2
seconds later) without me pressing the power button again. Does it mean
that it doesn't suspend, or that it just doesn't *stay* suspended ? Is
there anything to do for it to stay suspended ?

After that, I don't see any problem with X or with my network, or with
anything else.

I don't think I have any sleep button on this laptop.

Another thing: what is the laptop expected to do when closing / opening the lid ?

Thanks a lot for your work.
