I'm more frustrated w/ the n800 every day. In the old day, the nokia 770, I fliped the case over, and boom, screen lock& suspend mode all in one. On N800, I usually lock the screen every after use eg: hit power button follow by the square button, still it doesn't put the n800 into suspend(sleep) mode. I thrown(not literally) the n800 right into my DSlite case. And some time, after I picked up the n800 out of the case, the system ran out of the battery because it didn't go to sleep. I wonder if anyone have a hack that if I hit the sequence keys(power follow by square) and it put the unit into sleep+screenlock. Then I don't have to worry about the key or screen being press(sqeezed) in the case before it went to sleep.
