Hi again, I did some more experiments with the vendor BIOS and made the following observations:
- disabling "cpu power management" makes the idle consumption raise to 12,8W - disabling "PCI Bus power management" and "PCI express power management" makes the idle consumption raise to 13,3W - disabling the AMT firmware had no effect - running the stress test still drains only 24,2W - performance is the same as before I still don't understand the whole performance issue. Therefore, I took another X200 with a P8600, CCFL screen and an older vendor BIOS and re-ran the benchmark there --- with almost identical results. So in the end I'm just confused. This would mean that running Coreboot makes the X200 *much* faster at the expense of battery life, both in idle and under stress conditions. Any ideas which could solve this mystery?
