Arduino IDE giving a blow to battery back-up of PC When I have serial plotter open in the Arduino IDE with serial communication going on, the fans of my PC go full speed. On checking I found that Java(TM) Platform SE binary(32 bit) is using about 29% of the CPU.

This gives a big blow to the PC's battery back-up. Is there some way to reduce the CPU usage ? 


  The IDE version I use is Arduino 1.8.4


OS : Microsoft Windows 10 Home (64 bit)

PC : HP Au620 TX (laptop)

processor : Intel i5 7th gen (7200)

RAM : 8GB
Run Arduino IDE in a virtual machine which allows CPU allocation. Set a strict limit on CPU resources in that VM, like 200..500 MHz.
