Modify Arduino pro Mini

I am looking into this link https://www.mysensors.org/build/battery to modify my mini so that I can save the poer consumption.
I bought A mini from Aliexpress which looks like this
This looks different from what is shown on mysensors page. Now per mysensor I need to
- Disconnect the Arduino's power indicator LED by cutting the track between the LED and the resistor in series. Saves about 1.5 mA
- Disconnect the 3.3 VDC regulator because it is not needed. Cut the Vout pin with a sharp fine wire cutter. See images to the right on how to locate regulator. Saves about 220 uA
since my Mini looks different , I am having problems trying to cut the required components. Can anyone help how to modify the Mini I bought from aliexpress.
I use the tip of a knife to pry loose the power led. The power led is easily located by powering on the Arduino.
For the voltage regulator, I use a small side cutter / wire cutter to cut the two legs on one side. I then bend the voltage regulator up and down a few times to break the other three legs. It is a crude method but has worked well on the 20+ devices I have used it in on. The voltage regulator is the only component with two legs on one side and three legs on the opposite side.
Agree with @mfalkvidd and most of the times im even more ungentle (is that even a english word?).
I just out my soldering iron, heat the led/regulator up and push them away with force.
