Problem
The USB mouse or keyboard attached, either wired or wirelessly, will not wake the ThinkPad from the S3 (Standby) state by pressing the mouse buttons or the keyboard buttons if the USB devices are attached to the ThinkPad dock.
Limitations
This is not a limitation of the ThinkPad dock or of ThinkPad notebook systems. This function is by design.
NOTE: This issue also pertains to Wireless USB mice and wired USB mice.
Solution
Press the ThinkPad dock Power button to resume the system from the S3 (Standby) state or attach the USB devices directly to USB ports on ThinkPad system.
