Leopard Hangs when idle

[Magnetronkip]

Hi all,

 

i got a toshiba a200-1ck Laptop with succesfull running leopard 10.5.1.

when i am idle my laptop will hang after some 5 minutes. i got everything off at the power safe function even the "put the harddisk at sleep when possible" function. isn't helping

 

i searched the forums for some hours this week but nothing seems like my problem
