If the computer becomes warm during usage
• Check the usage environment
- Avoid using the computer on a highly heat retentive surfaces (e.g., rubber pads). If possible, use the computer
on surfaces that can dissipate heat, such as a steel desk.
- Do not use a keyboard cover, as this prevents heat dissipation.
- Always keep the display open in standby.
• Check the following
- If the computer becomes warm while the screen saver is displayed, set the screen saver to [Windows XP].
Screen savers that use 3-D images or other complex images increase the CPU utilization rate.
- If you are not using a wireless LAN, turn the wireless LAN off.
- Use recommended RAM module products. Non-recommended RAM modules may not operate properly, and
may cause damage to your computer.
• Double-click on the desktop and click [High speed], then click [OK].
- When you set [High speed], rotation of the cooling fan speeds up and the computer can be cooled down. Note
that the battery operating time will be shorter.
- When you do not frequently use CPU or the rotation noise of the fan bothers you, set [Standard] or [Low speed]
as necessary.
When Starting Up/Shutting Down

• Connecting or disconnecting the AC adaptor
