There's nothing in the plan that would put the computer to sleep after 3 minutes. You do have turn off hard drive after 10 minutes and I didn't convert but I believe 30 minutes on AC those could turn on the computer but only for a traditional HDD. If you have an SSD this setting does nothing. You also have shut off display after 10 minutes on DC (battery). I know HP has their own power utility but I don't know if it has it's own behavior or merely interacts with the Windows power plans.
