Snow Leopard sometimes does not shutdown

[Nocturnalist]

I've just bought MacBook with pre installed MacOS 10.6.1, then updated it to 10.6.2. Sometimes (approximately 1 of 5 times) it does not shutdown - there are only my wallpaper and active mouse pointer. I've been waiting for a long time, then just turned off it with holding power button. It seems I have a problem after high hard drive activity (a lot of copy, delete and move operation), but I am not sure. Could you help me, please?

Some people have reported the following works:

Go to Macintosh HD > Library > Preferences > System Configuration > and delete the files named Com.apple.autowake.plist and com.apple.powermanagement.plist. > and reboot the mac

This resets the energy saving preferences on you mac and hopefully should sort out the problem.

It is my first Mac and the biggest disappointment. I tried that solution with plist files yesterday. There were no file with name com.apple.autowake.plist. Another one I deleted, but after several shutdowns problem appears again.

This happens to me all the time. I will try to delete that plist and see if that helps.

As a last resort have you tried resetting SMC?

I will try to reset SMC (I've found manual for portable computers that have a battery you should not remove on your own at). Is it safe to reset SMC?
