After being left on 'sleep' for two-three days 10.5.6. turns off eventually.
Is that normal?
 
Do you have mild brownouts? Do the lights occasionally dim or flicker? You could simply be losing power for long enough that the power supply can't compensate while in sleep.

Is it "Safe Sleep" where the computer writes memory to disk and shuts down (analogous to Windows Hibernate) and powering on will reload the memory and leave you where you left off or (man, that was long) does it just lose power?
 
If you're not using it for over 24 hours, my advice is to shut it down. Sleep is made for shorter time, not for days.
 
If I leave my computer for that long I will always switch it off. My iMac is on all of the time as it is normally downloading podcasts or similar. My MacBook pro gets "put to sleep" whenever I have finished using it during the day, but shutdown overnight as I find it is a lot more responsive after a restart first thing in the morning.
 
Thanks for the replies, all.
No, as far as I know there are no burnouts.
I rarely let it sleep for that long anyway - although it happens on rare occasions.
Hmmm...
 
It sounds like a power issue. Technically, a computer can stay in sleep for forever, so long as it has the minimal amount of power that it requires to keep it's memory up. I can only reiterate what has already been said though, sleep is definitely not intended for that long.
What type of power source are you using? Surge strip, UPS, wall socket?
I keep my iMac, Mac mini (my home server), my linksys wrt610n router, and my Drobo all on a UPS. There are times when the voltage at my apartment fluctuates below 120v and the UPS is forced to kick in, although the power didn't technically "go out". You could have the same sort of problem.

Eh. I don't turn off my MacBook Pro. Ever. It'll sleep for days sometimes (rare that it sits for that long, though). I do restart when updates or a glitch causes me to do so (usually SMB sharing problems). Other than that, I only shut it down when I checked the battery info.

I was the same way with my PowerBook G3, my PowerBook 1400cs, and my PowerBook 190, as far back as fourteen years ago. I Hibernate my Windows desktop, because it is a power hungry beast. I use sleep on my Atom 330 computer here at work, and alternate between sleep and shutdown my main PC at work because Vista likes to install updates every other day or so.
 
Lol don't leave it on for more than a day, it isn't designed for that. Could either be power failure or that the machine shut down because you left it on sleep to long...
