[Lenny400] The sleep and the suspend state on Letux 400

[Dima]

Hi.

1. Seems that Letux 400 does not have sensors indicating that its lid is
   closed or open. Am I right ?

2. Does the Lenny400 system ability to put Letux400 in the `suspend' and
   the `sleep/hibernate' state. If yes, (1) how? (2) how is to wake it
   up from the `suspend' state?

Thanks, regards,
  Dima.
