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?

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.

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.)
