Can someone remind me how to set the battery charging style? was it software or windows? I remember setting the battery to charge for battery long term life, versus full charge for when i am needing maximum time unplugged. I have p35x v3 windows 10 x64 pro - latest updates as of 7-24-17 - The problem i am having is everytime i am using battery power after about 1 hour (or maybe 50 minutes) the laptop will just instantly power down with no warning. just a click and its off. Maybe if i can find that setting and change it to full charge it might condiition things to work longer or hopefully i can condition it through a cycle of charge/drains.
