Matt, It it is a Lenovo Thinkpad bios.., These bios options relate to Intel chipset, not specific to Lenovo brand.

I do not want to sound like I am advertising something, but I use program called Ccleaner It is great for viewing startup processes, cleaning registry from traces of old installations, and disabling items in startup. It could be that a Power Manager software (Dell, Lenovo, Acer etc.) is trying to kick in at some point and control power settings.
