Since last update of CentOS 7 (1503) and therefore kernel change to 3.10.0-229.1.2.el7.x86_64, bumblebee and bbswitch are not able to turn off nvidia card. Discrete card works fine but bug leads to high battery consumption. Everything was working fine on previous release. Method described here: http://elrepo.org/tiki/bumblebee used to install bumblebee.
Problem is still present with kernel 3.10.0-327.4.4.el7.x86_64:
[ 639.290565] bbswitch: disabling discrete graphics
