NullCPUPowerManagement.kext has nothing to do with ACPI patching.
It has to do with CPU power management.
With NullCPUPowerManagement.kext your CPU will not idle, and therefore will generate more heat, even not doing CPU intensive tasks.
 
hi RehabMan, I recently followed this tutorial to get power management on my laptop, but even after accomplish that, my battery life still stays at 2 hours top (from 100%). Is this normal?

The ioreg shows Nvidia is disabled.

I can get 3:21 hours from full juice (based on Activity Monitor). Is it normal?

Time remaining predictions will vary depending on what you're doing with the computer at the moment.

FYI: Your USB configuration is wrong.
