This laptop is HP Pavilion dv7-4272us. I'd be willing to help debug this problem, but I need some tools.
The first tool I need is a way to reliably turn off the DIS graphics & keep it off. The second tool would be a way to reliably turn off the IGD graphics & keep it off. Etc. When things keep switching back & forth for no apparent reason, I can't debug the situation. I did some Google searching, and it appears that there may be a way to disable certain PCI addresses during boot, which may be the only way to control this behavior. Thx for any help.
