Problem: Playback of DVD is not smooth in Windows 98 and 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. If the use increases, Intel SpeedStep
switches the processor speed to high.
v
Battery Optimized Performance: Keeps the processor speed low at all
times.
To choose a mode, do the following:
1. Start the ThinkPad Configuration Program.
2. Click Power Management .
3. Click the Intel SpeedStep technology tab.
4. From the list, select the mode you want.
5.
Click OK .
