I started X, told the battery monitor not to start on X startup, stopped X and re-started it, and the machine totaly hard locked. No Alt-Sysrq, no external ping.. no nothing.. After a hard re-boot, I can confirm that not running the ACPI battery monitor solves (works around) the problem. Problem being I now have no idea when my battery is going to die :p) Thanks for the quick response. -- Brad.... /"\ \ / ASCII RIBBON CAMPAIGN X AGAINST HTML MAIL / \
