It really shouldn?t be that hard to figure out. Get a power meter and run three tests. First test run laptop at full settings while plugged in with no battery. Second test run laptop for same period turn off laptop and see how much power it takes to charge it. Third test run laptop plugged in at the same power savings settings as on the battery to see how much power that draws.

Well not truly scientific it should yield a good result.

My bet is that the laptop with limited settings while plugged in would be the best. As the conversion from ac to spam deleted laptop battery and then battery to pc is a excess waste.
