One of my clients have this exact same issue.
When laptop ( ThinkPad X220 model 42912WG ) is inserted to dock while sleeping it wont resume from sleep anymore.
If i take DVD drive off from dock then it works fine.
Dock model: ThinkPAd UlrtaBase series 3 ( P/N 0a86464 )
Laptop BIOS 1.28
OS: Windows 7 64bit with Sophos 188.8.131.52 encryption.
