[ltp] sleep problems on T21

[no have]

i am just answering myself. i noticed a way to let the labtop sleep in
peace: disconnect the labtop from the source, meaning work on battery, then
you can switch the labtop to sleep, after that you may connect the labtop
with electricity if you like.
i couldn't manage to bring the labtop to sleep while it is connected to
electricity source.
i don't have any explation. but it works.
greetings.
