While making progress on my Dell Latitude 3330 I have encountered an issue while making the battery status work.
After reading the guide I found out I was very lucky as all my EC fields are 8 bit.
However after installing ACPIBatteryManager.kext the battery status was not working. By debugging the DSDT with ACPIDebug.kext I found that the _STA method of BAT0 was not returning. Digging deeper I found that it was hanging in the SNVC method, because the SMIB value was 0x00.
Reading the above lines I thought the SMIB value should be 0xDA7D6000 instead of 0x00. Thus I applied the following hack:
Now the battery status is working! See also this excerpt from the log:
While it is working, this hack does not seem "right". Why is SMIB 0x00? I have searched my DSDT to find out if anything is overwriting the SMIB variable, but could not find anything.
How is it possible that SMIB is 0x00?

Code:
Scope (\)
{
Mutex(SMIX, 0)
Name (SMIB, 0xDA7D6000)
Name (PSMI, 0x000000B2)
Method (SNVC, 1, NotSerialized)
{
\RMDT.P2 ("SNVC value SMIB = ", SMIB)
OperationRegion (WWPR, SystemMemory, SMIB, 0x04)
Field (WWPR, DWordAcc, Lock, Preserve)
{
SCDW, 32
}
Store (Arg0, SCDW)
}Reading the above lines I thought the SMIB value should be 0xDA7D6000 instead of 0x00. Thus I applied the following hack:
Code:
\RMDT.P2 ("SNVC value SMIB = ", SMIB)
If (LEqual (SMIB, Zero))
{
\RMDT.PUSH ("SNVC patch SMIB value")
Store (0xDA7D6000, SMIB)
}
OperationRegion (WWPR, SystemMemory, SMIB, 0x04)Now the battery status is working! See also this excerpt from the log:
