I'll probably add even more things later too.

Man, you rock! This looks great. Thanks

when i open dell efi, it says "it appears you are not installing on a dell mini 9, do you still want to install" any ideas?

Ignore it for now.

After several attempts I am giving up on 1.1.
The battery icon still displays the incorrect information and everytime I reboot a warning pops up telling me I am running on reserve power no matter if I have a full battery or its plugged in.

I wish I could get this one to work. I appreciate everything these guys have done.

This happens when the boot process cannot get the MAC Address somehow on booting. I have seens it a few times but no idea why..... Maybe someone understand the boot process know what the deal is. But reboot and usually it does not happen twice.

DellEFI tries to read the dell's built in nic's ethernet card. This problem happens when the drivers are not loaded up for it (or possibly if the wifi drivers are loaded first so that it reads a diff manufacturer). If the nic's drivers are not loaded, it wont have a MAC address and so it wont be able to detect if its running on a dell or not.

No idea if this is a dell efi issue or not, but is there any way to make the mini 9 actually go to sleep when it gets into reserve battery power (<5%)... the warning comes up saying it'll go to sleep, but mine always just dies once it hits 0% for a few minutes.

The easy way to do it is have the battery manager issue a sleep command. The good way to do it is to have it send a notification, and then have a user space program issue the sleep command. The even better way to do it is to figure out why the computer doesn't actually go to sleep.

I don't know if that kext is supposed to put it to sleep, of if something else is, but it would work.

Any idea which kext is responsible for this? I was digging through the AppleSmartBatteryManager and pmset code and didn't find anything specifically responsible for setting sleep... (pmset does have some variables like kIOPSLowBatteryWarningFinal kIOPSLowBatteryWarningEarly, etc but afaict I it doesn't do anything with them...)

It's weird, apples code doesn't seem to do anything when it gets a final low battery warning:

    /* Display a system low battery warning?
     * 
     * No Warning == AC Power or >= 22% on battery
     * Early Warning == On Battery with < 22%
     * Final Warning == On Battery with < 10 Minutes
     *
     * Once we enter a "warning" state, we can only leave "warning"
     * state by (1) having AC power re-applied, or (2) hibernating
     * and waking with a new battery.
     *     
     * This prevents fluctuations in battery capacity from causing
     * multiple battery warnings.
     *
     */

 if ( (intLevel >= 22) 
            && (_systemBatteryWarningLevel != kIOPSLowBatteryWarningEarly)
            && (_systemBatteryWarningLevel != kIOPSLowBatteryWarningFinal))
        {
            newWarningLevel = kIOPSLowBatteryWarningNone;
        } else if (combinedTime < 10) {
            newWarningLevel = kIOPSLowBatteryWarningFinal;
        } else if (_systemBatteryWarningLevel != kIOPSLowBatteryWarningFinal)
        {

That's from BatteryTimeRemaining.c, part of pmconfigd...

One solution could be to add a sleep call in the else if (combinedTime < 10) {} branch...

PSLowPower.c gives me a hint how real macs do it though:

            // Do not do UPS shutdown if internal battery is present.
            // Internal battery may still be providing power. 
            // Don't do any further UPS shutdown processing.
            // PMU will cause an emergency sleep when the battery runs out - we fall back on that
            // in the battery case.

So it looks like its the PMU's job to issue the final sleep call on a real mac...

Also, kind of funny, but apples code comments indicate PPC batteries did not supply accurate charge information at all
