When using multiple graphics adapters (including Optimus with a docking station), the display configuration might be lost when rebooting on the W510.



On an Optimus(R) ThinkPad system, the digital output ports on the dock are connected only to the nVidia graphics device. As such, when docked the system can use both graphics devices (Intel integrated and nVidia discrete) to output to four displays. However, when in this configuration, sometimes the display configuration (which displays are active, which is primary, what are their resolutions, etc.) might be lost during the system reboot.



Unfortunately, this appears to be a present limitation under Windows 7 - please see Microsoft KB article below for more details.
