hybrid sleep mode

[Atol]

Hello I am new here.

computer setup

17" WideUXGA 1920 x 1200 LCD with Clearview Technology
Intel® Core™ 2 Duo T8300 2.4GHz (3MB Cache 800MHz FSB)
1GB of ram
320gb hard disk and 120gb hard disk. Soon 120 ssd drive.
Dual 256MB NVIDIA® GeForce® Go 8600M GT – SLI Enabled

Basicly when I want to watch tv I eather close the lid or manualy set the computer for sleep mode. So it save where I am at. Keyboard laptop light turn off and the Alienware head slowly glows off and on. Which is what it what it should do. When exiting sleep mode.

Now 15% to 20% of the time

1 The computer turns off Automaticly and when you reboot you get the message Your computer did not turn off right do you want to restart windows normaly.
2 The computer turns off automaticly and when you reboot windows starts up normal.
