Your machine supports the C4 state. Change the P_BLK in your DSDT to 0x06 e.g.: Processor (\_PR.CPU0, 0x01, 0x00001010, 0x07) to: Processor (\_PR.CPU0, 0x01, 0x00001010, 0x06) or use the patch from Pavel, posted on the 28.02.2004, 17:10. Unfortunately this won't enable the C4 state if you have one. What do mainters say about supporting Cn processor states in the future? ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
