【原创】谨慎购入新版扩展坞！！

maimaitou

为T440S入手了新版的thinkpad ultra dock发现一个严重问题，当dock外接着音响时，移开或者关闭笔记本都会造成音响发出很响的嗡嗡声，移除dock电源也没用。打客服前后换了三台都是一样的情况。上网一查发现不论是ultra dock还是pro dock大家都是一样的问题：

从此帖得知联想在上个月已经出货修正版的扩展坞了，换了FRU，貌似解决了问题，现已打电话请求更换，请最近需要扩展坞的兄弟们留意，避免买到旧版的扩展坞。
对于ultra dock，有问题的那批FRU是 04W3947，最新版修复问题的是 00HM917。
pro dock的FRU还不是很了解。大家谨慎购入！

另外，那么一个简单的接地问题都解决不好，这已经不是品控问题而是设计问题了。

更新：今天下午联想北美客服给我打了个电话要了问题底座的FRU，说马上发个新的过来，但无法确认replacement的FRU，等收到了再来更新。

更新联想官方的回复：
All,

These symptoms (discussed in this thread) may not be universally experienced and this is not a recall, but if you have this issue, then please contact service during warranty.

In this case, there are new parts for the dock.

Ultra dock    Old FRU 04W3947 -> New FRU 00HM917

Pro dock       Old FRU 04W3948 -> New FRU 00HM918

You should contact the support number for "Think" service is your particular country.

If the agent seems unaware or is having difficulty finding information, suggest that they sign into the support site, select the system model (like T440s) that you have the dock attached to normally, and then have them select tips and then look under the section for sound.

I'm marking this as the solution for this thread.

Thanks

Mark
