rebooting problem

[chuckbear]

About a week ago a strange new problem started. I have a Toshiba laptop with Vista Home and dual core processor. Lately on SOME occasions the computer reboots itself when I close the lid. It does not do it every time and will shut down fine every time normally. But on some shut downs, when I close the lid the system reboots. It might do this a couple of times in a row and it might not do it for 3 or 4 shut downs. I use the shut down from the start menu. I have changed all of the setting for power settings and what to do when the lid is shut to either never or do nothing and it does not affect it. This computer is only about 4 months old. Any thoughts? I have done a restore point before this started but no help.

Do you have hibernation mode enabled on your notebook?
Vista SP1 had a bug that messed up the hibernation shutdown . Instead of resuming from hibernation it went into improper shutdown and rebooted.

not sure where the hibernation mode would be enabled. This is not from hibernation shut down, just a normal shut down.

thanks guys but it does not help. Hibernation is not the problem . the problem is the computer starts itself back up when I close the lid on the laptop after a shutdown. Only when I close the lid.

Perhaps it is a setting in the BIOS. I am not familiar with laptops, but can the BIOS control this?
