X1 Extreme Gen 2 cover has a screw which had ripped the threads

2019-12-14, 11:31 AM

I noticed that the middle front screw, next to touchpad has ripped the threads completely. The screw turns endlessly if I try to turn it. Does anybody else has this or is it just me? I opened the case and I can confirm the threads have been ripped of the frame. And the screw itself is in perfect condition so it seems like a assembling machine with a perfect head for the screw has turned the screw and it has been set to too much torque. Lots of talk about loose screws on the sides or corners but how about this one screw on the middle? Do you mind trying to tighten the screw and see yourself? I attached a photo and circled the screw without threads.

I have the same problem with that exact screw. The threads are ripped from the frame, the screw is fine.

Is there any data on how prevalent this issue is? I had a ripped thread myself, and even after a replacement of the bottom cover and the mid-chassis, there is still relative displacement between the bottom cover and the chassis in the front right corner. Is there any internal knowledge about a design error or any problem with a certain batch of parts? How is the rigidity of the bottom cover attachment evaluated by quality control?

I looked very closely at the issue. I believe there is a gap between the back cover and the battery in which the screw does not take up that slack. Also the plastic tabs on the bottom of the case on the right side (upside down with trackpad facing away from you, fans nearest you) seem to be too thin therefor creating a gap when they "lock" in to the midframe. I'll try to grab a pic of the issue today. Also the screw doesn't seem to travel deep enough into the threads in the mid chassis. There's all sorts of different length screws used in this bottom case vs the S340 which were all the same. (Did a memory swap on 2 S340's yesterday so I had the chance to compare and look around). IDK why they didn't use brass inserts instead of threading directly into soft metal and only using one screw near the bottom. The s340 has 4 screws near the bottom vs 1 on a $2000 laptop. Nuts. Whoever was in charge of that design was an idiot.

Thanks a lot for sharing these insights! Let me know in case you come up with a good idea for workarounds or potential solutions to alleviate the issue. I wonder how this design could make it past the drafting stage and go into production, and how many people signed this off... it's just puzzling how this went into production and then on top of that, would not be detected by some measures of quality control.

Thinkpads are not what they used to be when IBM owned the brand. I'll keep you posted as I'm working on a fix. I'll shoot you a msg and post it on my blog when I'm finished.

Thanks a lot! Yes, I fondly remember my old X41, T43, and other older IBM Thinkpads, those devices were amazing.

I ripped three of them by myself. They are just too delicate.

You destroyed the threads in the holes or the screw threads?
