I looked it up on wikipedia and "sleep" is the correct term. The power
switch blinks slowly and the sleep light comes on.

The machine has settings for integrated/discrete/optimus. Under FBSD,
I use discrete. The card is an nvidia nvs5400m, driver version 331.67
(I see now that the only driver versions ever used on this machine
were 331.49 and 331.67; initially, I started of with the integrated
Intel graphics, which had its own set of problems). Yes to new xorg
and kms.

I can reproduce this behaviour at will - boot up, log into desktop,
and press e.g. F5-F6 repeatedly (F5 - wlan; F6 - camera+head set).
Within seconds, the system goes to sleep, and I can recover by closing
and reopening the lid.
