PCI Express Active-State Power Management (ASPM) Disabled

[kay.one]

I have X201 and I noticed that I'm not getting more than 3 hours out of my laptop. so ran powercfg -energy

I have a few questions, (I have attached the full report)

is there a way to fix this? new drivers?

Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled
PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer.

and also i have an ssd installed. I thought windows is supposed to know your are using an ssd.

The disk is not configured to turn off after a period of disk inactivity.

Full Report


i tried posting this on X200 series forum but no replies after a few days, so I'm trying it here. (sorry for double post.)

My T410 gets phenomenal battery life (Close to 10 on a 9 cell). I did the powercfg -energy report and ASPM also reported as being disabled.
I have a 320GB 7.2k Hitachi (7k500 to be specific) and it also complained about the lack of disk-spindown. (I have it set not to.)
