Solution: Be sure that the disk meets the standard for your country. Usually, a

disk that meets the local standards is marked with a CD logo (as shown

below) on the label. If you use a disk that does not meet these standards, we

cannot guarantee that it will play, or that, if it does play, the sound quality

will be good.

Problem:The system shows slow performance.

Solution: This problem may occur when the ac adapter is not attached. To

prolong battery life with the higher frequency of Intel’s Pentium 4/Celeron

processors, the ThinkPad G40 implements the Dynamic CPU Throttling

feature, which reduces CPU frequency dynamically: 1) when the system

operates in battery mode; 2) when the system increases power consumption;

3) when system temperature increases.

To avoid or reduce this problem, do one or all of the following:

1. Attach the ac adapter.

2. Close applications not being used.

3. Try to lower system temperature by increasing the fan speed with the

Battery MaxiMiser Wizard with Fan Control.
