Well - the power of the "Search" function. Onan has asked exactly my question, and I too was told that you don't need passwords (and I certainly don't want one).
Did anybody get any further? My desktop PC runs 24/7, my laptop plugged in when I need it.
Use laptop to run as an alarm clock when I'm on the road (hotels) and it wakes me with nice music - but means that I (currently) have to have a password - which means I have to enter it every time I power up. Not good.
Repeat of paragraph 2. Did anybody get any further?
