Without this plan windows and the Lenovo configured hardware do not cooperate correctly and the power slider and other settings were missing. We have had to side load this into our new windows 10 Pro install so that we gain optimal performance from our hardware. There are numerous setting within this LENOVO OEM build power plan (Lenovo Intelligent Power) that are required for the P53 model to actually operate correctly.
I tend to disagree with you that it does noting, in our case on the P53 model we saw significant performance problems without it.
