One of the great things about Lenovo ThinkPad systems is that they may have a dedicated docking station. This is especially useful if you like to connect many things to your laptop and then get annoyed when you have to unplug all of those cables. With the docking station you can connect all of your USB accessories and external displays and leave your laptop free of the clutter. Basically a docking station turns your laptop into a "ready for work" desktop.
I was going to the X200 Ultrabase from Amazon but Lenovo included it along with the review X201T unit. There are many sites like eBay that may have this docking station for a lot less money, so shop wisely.
Along with the convenience of "dock" and "undock" there are a few other extras.

DOCKING DISPLAY MODES
One of the advantages of the X201T is being able to use an external display. The external display can be a computer monitor, projector, or TV.
You can change the display modes by pressing the Win + P keys.
Disables the external display and enables only the X201T's screen.
This mode is also known as "clone" mode. The X201T's screen is cloned/duplicated to the external display. Some TVs and projectors will not support some resolutions.
This adds the screen as a secondary monitor. You can have different windows on each screen.
Disables the X201T's screen, and only the external display is enabled.
The system keeps the docked and undocked resolution and display mode saved. When you dock your X201T again it will automatically restore the previously set display mode.
DO NOT SLEEP WHEN LID IS CLOSED
If you keep your X201T in laptop mode and you close the lid the system will automatically go into "sleep" mode. When you dock the system you may want to close the screen, but keep the system on because you are now using the external display. So you have to change the automatic sleep behavior.
How to disable automatic sleep:
Now you can close the lid of the X201T while the system is docked or powered via the cable. It's a much better experience.
X201T LOSES WIFI AFTER UNDOCKING (FIX)
If you dock and undock your X201T from the UltraBase many times you will "lose wifi" connection after undock. There are several ways of reactivating the wifi.
Method 1 (Troubleshoot through Windows)
Method 2 (Disable and enable wifi card)
Method 3 (Reboot/restart computer)
Hopefully one of these methods fixes the problem.
