Using Applescript to Sleep Computer

I tell it application "System Events". also run 10.5.5 and have no delay.

I use this:

--pmset changes and reads power management settings such as idle sleep timing wake on administrative access automatic restart on power loss, etc.

set current_mode to do shell script "pmset -g | grep mode" --look for current hibernate mode

if current_mode contains "3" then set the current_name to "sleep" if current_mode contains "1" then set the current_name to "safe sleep"

display dialog "I'm in " & current_name & " mode. Set new mode!" buttons {"sleep", "safe sleep", "cancel"} default button 3 set new_name to button returned of result

if new_name is "sleep" then set new_mode to "3" if new_name is "safe sleep" then set new_mode to "1"

do shell script "pmset -a hibernatemode " & new_mode with administrator privileges

display dialog "Go to " & new_name & " now?" buttons {"yes", "no"} default button 2
if button returned of result is "yes" then tell application "System Events" to sleep
