You should try using "Offline mode" from the power menu. Presence thing
in statusbar uses WLAN now and then, there are also some WLAN APs with
bad power management.

If that doesn't help, then you could try closing all applications
if you've left any open and disabling all Home applets.   As you
don't have really much 3rd party stuff installed, that shouldn't
be an issue though, but if it affects things, we can go through
things you had open/enabled.

Only for real boot.
