Resume problem on X220t with dock

Hi, I recently purchased the docking station with the DVD reader in the ultrabay. So far, things are working smoothly and I'm very happy with the dock. I do however run into a resume problem everytime my tablet is docked. Whether the laptop is put to sleep on the dock or put to sleep undocked and then attached, when I open the lid, the laptop won't resume. Any press (short, long) on the main power button doesn't do the trick either. I have so far only been able to get it to resume by pressing the power button on the dock on the power button on the screen for about 5 seconds. A short press on these doesn't work The same problem occurs when the tablet is turned off: no way to power it on using the main power button once it's docked. I'm running Win7 x64 with the latest BIOS and drivers (just reinstalled everything last week hoping to solve my touchpad problem -- which I assume is completely unrelated). Thanks for your answers, -LP

Re: Resume problem on X220t with dock

hey LordPhoenix,

i would believe that your Bios version is at 1.21 ?

Anyway, try this

- uninstall all Thinkvantage software.

With all the ThinkVantage software removed, test and see if the same thing happens.

OS: Windows 7 64bit with Sophos encryption.
