I have a laptop with hybrid Intel/AMD graphics. As far as I know, the configuration is muxless. This causes not-detection of discrete graphic card. And now my problem: I don/t know how to turn the discrete card completely off. I think it is powered all the time, because of critically short battery work time(approx. 3 hours instead of windows 7-8). Tlp and adjusting the brightness do not bring expected effect. I would really appreciate any help.
