I'm having power management problems with my X200. Running W7 Enterprise x64 RTM with 3.05 BIOS (no significant changes in 3.08).
I've upgraded to most recent version of WWAN card but even after restart it does not go into power saving mode.
USB peatamine:USB-seadet ei peatata
USB-seade ei läinud peatatud olekusse. Kui USB-seade ei lähe mittekasutamisel peatatud olekusse, võib protsessori energiahaldus olla takistatud.
Seadme nimi Ericsson F3507g Mobile Broadband Minicard Composite Device
etc.

Seadme nimi USB Root Hub
It's localized, but the idea is that USB device didn't shut down and it may break power management. The root hub seems to be the one connected to WWAN card, but information is too scarce. It's just a logical conclusion.
Platvormi energiahalduse võimalused:PCI Expressi aktiivse oleku energiahaldus (ASPM) keelatud
PCI Expressi aktiivse oleku energiahaldus (ASPM) on selles arvutis teatud riistvara ühildumatuse tõttu keelatud.
Something is keeping PCIe power management disabled and i can't figure out what, because documentation (WMI, device manager etc) is very scarce. I can't find any tool that can report me the status of ASPM.
It's also reporting that WiFi power management does not work properly, but i guess it's because transmit power is set to default medium. Power profile has it set to maximum power saver.
To check out power managent yourself, run "powercfg -energy" from elevated command line.
