Hey guys. Im having issues with an ultrabase I bought for my x61. The latch for releasing the laptop doesnt fully close, which causes the docking system to not work properly and cause different issues while I try to use it. I was gonna tear it apart and try to figure out whats wrong but I decided to ask you first, since theres not many ultrabase repair info online. Have any of you guys had a similar problem with this or other ultrabase? thanks

I did tear down 4337 dock once - in order to remove the grill at left-far-from-me corner. There is a theory that it partially blocks the vents on X220/T520 and besides you got to remove that if you want to also dock an X230T there. I followed some video on youtube. I was able to take it apart and put it back together. I'm unhappy with the result btw, X220/T520 have become much harder to dock Perhaps I should have cut out half of the grill to allow better air flow but kept the other half to allow me to place X220/T520 into them easily. So I'm using my other unmodified 4337 now. I'm not sure if this helps you at all though..

Never had this issue, but the latch-lever operates as a pusher, while there is a return spring. Check the return spring that should return the lever to the start position, if it has gone awry it could be the source of your blocking.
Good luck and remember take pics to see how things were while you opened it!
