Solving computer problems To avoid or reduce this problem, you can choose any of four different modes of operation other than Maximum Battery, 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. v Maximum Battery: Switches 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. 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. Problem: If you have been using Windows 2000 with the ThinkPad Dock attached to your computer, and you then detach the ThinkPad Dock while in standby mode, the system may not respond at all. Solution: Reboot the system. To avoid recurrence of this problem, be sure to detach the ThinkPad Dock only when the system is operating or turned off, not when it is in standby mode. 26 ThinkPad® T23 Service and Troubleshooting Guide
