    Are the drivers working ok now for the switchable graphics? Last time I checked people were having issues with both GPUs running at the same time and killing the battery.

    That problem still persists but can be fixed by swiching back and forth once between the integrated and ATi GPU's after the PC is woken up from sleep. AFAIK lenovo hasnt released an update to the driver yet.
