There seems to be a problem on many of the Compaq systems where the thermal and battery zones do not properly initialize if AC power is applied at power-up. My Compaq Presario 2710CA has this problem, and if I power-up with no AC to after the BIOS has initialized (Boot loader appears) then all is OK with both the battery and thermal zones. The later BIOS updates from Compaq have still not resolved this issue. - Troy On Wed, 2002-10-09 at 14:25, Kevin Schmidt wrote: > I have a Compaq evo n1000v which is very similar (the dsdt says n800). > I am running 2.4.19+xfs+acpi-20020918 with a patched dsdt. > The dsdt changes were: > 1.
