I was able to fix this by disabling the Nvidia GPU, running only on the integrated Intel iGPU. After Windows was installed, it seemed to work with the dGPU enabled, although no drivers made it mostly useless.
However I have a friend with a Broadwell laptop, E5450, and they get this with the ACPI. No dGPU to disable, going to have them look through the BIOS to see if they can find anything.
