Problem: Playback of DVD is not smooth in Windows 2000. Solution: If you select the Maximum Battery mode for the Intel SpeedStep® technology, this problem may occur. This mode is designed to achieve maximum battery life by switching the processor speed between the regular low speed and half of that speed, depending on how much the processor is used. If the use increases, Intel SpeedStep switches the processor speed to the lower speed. Operation in this mode can severely degrade the performance of the processor, and thus cause the playback of a DVD to be jerky. To avoid or reduce this problem, you can choose any of three other modes of operation, as follows: v Maximum Performance: Keeps the processor speed high at all times. v Automatic: Switches the processor speed between high and low, depending on how much the processor is used.
