CUDA switch
//draft
"The CUDA switch restarts the Power Management Unit, which operates the clock from the 4.5v battery, and allows the computer to power on/off among other things. The PMU is responsible for keeping the NVRAM active, which holds PRAM data.
Cmd+Opt+P+R resets the PRAM data to the default state only, leaving the PMU as it is."
