关于40AC扩展坞的问题
本帖最后由 l4433 于 2024-2-4 09:55 编辑本人目前使用X1 9th，闲鱼淘了一台洋垃圾40AC扩展坞（自带135W电源和雷电线），买回来后出现了奇怪的问题，开机无法识别扩展坞（主要表现就是无法扩展到外接屏幕），但是扩展坞上面的电源按钮可以使用（按这个在开机状态下可以进入休眠模式或者关机）， 需要反复插拔扩展坞电源直至电脑能够识别到它并自动扩展屏幕，一旦识别成功一次，接下来一天无论是重启、关机再开机后都能够正常识别无误，但是第二天上班又是重复前面的问题，本人已做如下尝试均未解决问题：
1.重新购买了100W的雷电4的连接线，问题依旧；
2.从联想美服官网下载40AC驱动并安装，问题依旧；
3.根据网上的教程修改BIOS里的雷电安全设置，却发现只有PCIe-Tunneling开关选项，无教程所说的用户安全选项；
4.去ThinkPad官方售后看过，当场使用售后的T480p及其他X1测试无异常，无法现场复现故障；
5.更新雷电4驱动，如果通过反复插拔电源是可以在雷电4控制器里看到40AC的信息的，如图；
6.无论电脑识别40AC与否，刚插上（我都是插电脑非供电口的C扣）时都会提示慢速充电，请更换原装充电器，我就怀疑是不是供电不够，遂在供电口插上笔记本原装电源再连接，但问题依旧，还是需要反复插拔40AC电源实现识别，目前购买了个150W方口电源还没到，到了测试一下看能够解决这个问题。
请问各位大佬能够判断出故障原因及给出解决办法么？跪求了

150w电源到了，试了试，问题依旧

花费600更换40AN00135CN的洋垃圾，完美解决问题。
看上去还是40AC的洋垃圾不太稳定，打算海鲜市场出了算了
感觉是不是你买的洋垃圾不太好啊。
我买的应该也是洋垃圾 说是全新的
接X1C 2018 以及X1C 2021都长期使用 无任何问题 zhangyongtao 发表于 2023-12-18 09:53

主要是你说他不好吧，一旦通过反复插拔电源成功连接，一天之内就一直可以正常使用，无论重启关机多少次进入系统后都能够正常识别，你说他好吧，有时候要反复插拔电源10几次才能正常识别，有时候插拔1,2次就能识别，真的奇怪 l4433 发表于 2023-12-18 10:03

应该是芯片或者固件问题
我之前用过一个客户的40A9 DP 只能用一个 zhangyongtao 发表于 2023-12-18 10:26

那请问最后解决这个问题了么？ 纯小白不懂，个人感觉是扩展坞供电有点毛病。
或者是你的本子跟扩展坞之间的连接有点毛病。 biandou000 发表于 2023-12-18 10:47

估计是，所以买了个150W的电源试试看 我也同样的问题，基本上要拔插几次外接屏幕才能显示。 看下雷电控制中心，
管理批准的雷电设备，要批准。是不是这里问题 lhmclhmc 发表于 2023-12-18 15:45

但是这个软件无法添加批准自动连接的设备，连添加选项都没有，我打算再去BIOS里面研究一下 升级到最新固件了吗？

升级了，问题依旧
有条件的话，换一台显示器试一试。偶尔会有某些显示器不兼容。我曾经用过X1C2018+40AC+EIZO(EV3237)这种组合，遇到过和你描述的一样的现象，换一台LG的显示器就没问题。后来升级40AC的固件后有改善，再后来电脑换成X13(Gen2, intel)就没再发生这种问题了。 40AC扩展坞，自带135W电源和雷电线，接1个4K+个1080,正常使用2年多了 l4433 发表于 2023-12-18 09:48

从该扩展坞在售后与其它主机测试无异常情况来看，感觉主机有电源控制部分有硬件问题，处于接近临界状态，造成该主机与该扩展坞匹配在临界状态，建议带该扩展坞与该主机同时去维修站看一看。估计买更大功率的电源不一定能够解决问题。如果情况属实，那就是时候换主机了。 yx2web 发表于 2023-12-19 09:02

我的nano出过类似问题，建议关机状态下按住开机键不动三十秒，就解决了。 biandou000 发表于 2023-12-18 10:47

刚试了最后一个方法，问题依旧，40AC在供电状态下连接依旧只充电，雷电控制器里不识别，但是在连接X1C的状态下拔掉40AC电源再重新接上立马识别，应该就是供电的问题，看我的150W电源到了之后能不能解决问题 l4433 发表于 2023-12-20 09:13

很奇怪啊，我的135W电源是没问题的，而且还是咸鱼买的二手联想电脑的电源。
建议你排查一下电脑的问题
另外注意是电脑关闭状态下按住开机键30秒，别松动，松动就会开机，这个办法就不行了
还有的人用别针点击reset之后成功的。 l4433 发表于 2023-12-20 09:13

另外建议准备一个无电源的雷电拓展坞排查一下，比如贝尔金或者绿联的
我那个是换了拓展坞发现是电脑的问题。 本帖最后由 moyu 于 2023-12-20 14:24 编辑

这个BUG的部分型号解决方案是升级9月底发布的雷电驱动1.41.1379.0后关闭雷电的PCI-E隧道。
第一感觉像是某个电容失效了 zhangyongtao 发表于 2023-12-18 10:26
应该是芯片或者固件问题
我之前用过一个客户的40A9 DP 只能用一个
同。感觉挺无奈的。我联想官方旗舰店买的，也是同时只能一个DP用。另一个显示器的输出只能靠USB-C。 我感觉是线/接口的问题，找一根苹果的80cm 雷电3的线，我记得X1 C9两个口都是雷电4，换一下计算机那面的口。 估计是扩展坞坏了吧，我的是40AF接X1c gen7，直接使用无任何问题。
