If I don't switch to the console, the screen actually brightens instead of darkening...<BR /><BR />Any ideas? Btw, the documentation says that the BIOS settings for power management have to be changed using Windows utilities; however, my sysadmin won't let me have both Windows and Linux on the machine. Are there any Linux tools to configure these parameters?<BR /><BR />Thanks a lot,<BR />Stephan Thu, 06 Feb 2003 14:00:30 GMT https://community.hpe.com/t5/operating-system-linux/evo-n610c-power-management-linux/m-p/2898382#M78180 Stephan Merz 2003-02-06T14:00:30Z https://community.hpe.com/t5/operating-system-linux/evo-n610c-power-management-linux/m-p/2898383#M78181 Stephan,<BR />I've experienced similar problems with RH7.3 XFree 4.2.
