Using 18kmon may be no longer necessary, it's best to update the bios first and see if this fixes the problem.
Here's info on the bios update: http://linux.dell.com/wiki/index.php...dellBiosUpdate
On my Dell XPS M1330, fan speeds seem normal after a bios update and switching to the nvidia 173 driver on Intrepid, though the fan seems to run more than normal after wakeup from sleep (anyone else have this problem?). It seems the fan can't shut down once revved up after wake up.
Does anybody have good information on whether or not this is necessary after upgrading to bios update a13 on an xps M1330? I'd be interested to hear anyone's thoughts.
