• The thermal control may set the computer to hibernation if you use the computer in a high ambient temperature
and use an application that uses a lot of CPU power (for example, playing DVD-Video over an extended period).
Wait a few minutes (at least 5) before turning the computer on again if this occurs.
You can change settings to make it less likely that the thermal control will switch the computer to hibernation, even
though this will slow down application processing speed, and may result in less smooth video. Go to the Setup
Utility [Main] menu and change the setting for [Thermal Control] to [Extended].
