Does the hard drive light stay lit at that screen?

Re: T400 boot hangs at ThinkPad splash screen

A common cause on that model is a damaged USB port. (plastic tab broken off) You can unplug, remove the battery and try to straighten the pins enough so they are not shorted to each other or to the side. If you can do that, you can use the machine, but, obviously, not the port.
