That's what I thought. I'll review my power settings.
Thank you for your assistance

Hi guys, I have an HP PROBOOK COREi5 laptop with 2 switchable graphics cards, an INTEL HD GRAPHICS 4000 and an AMD RADEON HD 7500.
I have installed and configured CGWATCHER with CGMINER.
MINING works well with the AMD GPU.
The problem is that MINING crashes when I plug the laptop into the mains to recharge it.
My laptop crashes too.
Can someone help me to fix this problem, please
