Something appears incomplete in Chameleon's SMBIOS manipulation. These SMBIOS issues have been causing power management issues on 10.5.8/10.6 for laptop users - the Asus Eee series in my case. Battery and power management partially work:
The battery menu extra shows the proper battery status, and changes appropriately for AC vs battery usage
System Profiler appears correct, showing the battery, whether the system is charging, etc.
However, the text on the battery menu extra incorrectly says "Power Source: AC Adapter" when on battery
Energy Saver pref pane doesn't show battery vs AC options - just AC

I bring it up here, because to fix it, one needs both Chameleon's smbios.plist and a modified AppleSMBIOS.kext. In other words, I can put the same info in an smbios.plist and in an AppleSMBIOS.kext, and with one or the other, nothing is fixed. But with both it is.

I related it to Chameleon, as the fix for this is SMBIOS-related, and it seemed odd that Chameleon's SMBIOS support couldn't fix it on its own as I would have expected. Is this something we might see in rc3?

ioreg output is up at http://diamondsw.dyndns.org/Misc/SMBIOS.zip . I included output for when using only an smbios.plist and when using both that and a kext, and for when on AC and when on battery.

I've parsed through the two battery files, and the most likely difference is the following - without the kext, ChildrenPowerState doesn't exist:
Code: [Select]
| | +-o IORootParent <class IORootParent>
| | | "IOPowerManagement" = {"CurrentPowerState"=4,"DevicePowerState"=4,"PowerOverrideOn"=Yes,"ChildrenPowerState"=4}
Interestingly, when the system is on AC, the plist and plist+kext both have the "ChildrenPowerState"=4 key properly set. The only configuration that doesn't show "ChildrenPowerState" for that key is plist-only-battery, and it's only on that one key that it's missing. And of course, that's where we're seeing the strangest behavior.

You might find something I missed in the various other chunks of hex, but that one stands out to my amateur eye.

Hi, the link you posted to the zip file doesn't seem to be working.
