Well, the 'settings' are there on every reboot and are correct? Why should another reboot make any difference?
Update: I had an email 'trawler' (Mailwasher) set to trawl every 22 minutes (power settings at 20) but by changing that to 25 I seem to have cleared the problem, so I assume the timing of Windows 20 or Mailwasher 22 was not accurate.
