Mac OSX 10.5 auto shutdowns

[strack]

Hi, I'm still very new to Macs. I've been having this auto shutdown problem ever since I upgraded to 10.5 from 10.4. I'll describe it as follow,

With the current 10.5 OS X, with the power supply continuously feeding my MacBook Pro, this auto shutdown problem will not occur. It only occurs when I'm running purely on battery whereby once it reaches around 80%, it'll just shutdown for no reason.

I've checked the energy savings options, don't see any options to result in the above.

Would appreciate any feedback on the above. It is very traumatising to be outside with a full battery life when I can only utilise only 20% for it.

btw, its on 10.5.1. I doubt 10.5.2 can resolve this problem so thought I'll ask about it first.

Thanks!!

Upgrading, if that was the path you took , caused a lot of hassles according to posts. Maybe back up the drive to external and do a clean install.

You could try and check under Preferences - Security - General and ensure the check box to auto logout after x amount of time is not checked. That was one of my problems....

Thanks for the feedback!

Doesn't seem like the problem's with auto logout. Reinstalling the whole OS would really be a last desperate resort for me.

Ok, should have checked the official Apple support too.

Seems like this is not an uncommon problem.
