"If Macrium disables sleep mode while it is writing a backup, and re-enables it when it has finished the backup, what's the problem? Am I missing something here? (I use Macrium myself)"
If it actually did that (re-enable) it would have been fine. For me it did not. After reading some of the links that Geek sent I found out that I was not the only one. Threads in the Macrium Reflect Forums had others having the same problem away back when. One fellow was so upset that he was going to reload Windows.

You're the manMaybe the problem is really Vista.
Maybe this is a fix.
http://www.howtogeek.com/howto/windows-vista/disable-hybrid-sleep-mode/I was so sure that I tried all of the things mentioned in the previous links but I tried again with this link and this time it worked out perfectly. One thing that is different now, when the start button is clicked for( shut down options or?) the hibernate option is shown.
Within the sleep option in power settings, hibernate must be set to off. If the hibernate setting is set to on, the hibernate option does not appear with the start button. Sleep is shown(with start button) whether hibernate is off or on ( in power settings) but again sleep will not work without hibernate showing?. Thanks so much. overthehill
