Hello, Rehabman. Is your repository up-to-date? I installed Sierra from scratch in a Probook 640 G1 (Haswell) and had issues with power management (no battery/plug detection) and screen graphics. I did it a couple of times to make sure I was not screwing things up. All problems disappeared when I replaced the ACPI/PATCHED folder with the PATCHED folder of an older installation, which suggests that some recent change is the culprit.
