的两个口接绿联的扩展坞指示灯都不亮，usb也不识别，扩展坞在别的电脑上是OK的，是不是只能换主板了？

据说绿联的扩展坞烧主板，听说而已，我也没有证据。

回馈一下版友，在各种搜索之后通过下面链接里面的办法问题已经得到解决，看起来并不是主板硬件问题。

以下方法我只把Step 1做了一次，就解决了问题。

Try the following:

Step 1. Static Discharge
- Remove all cables attached to the device (ac adapter/power, hdmi, external mouse/keyboard, etc)
- Ensure device is switched OFF
- Hold down power button for 60 seconds
- Re-attach all cables
- Connect the AC Adapter, then let the device charge for about 2 minutes (if it does) then start up as usual.
- Try this a couple of times in case it doesn't solve the issue the first time (2-3)

Step 2. No display after wake from Power save mode/sleep.
External monitors lose display after wake from power save mode/sleep mode.

Check if the Thunderbolt icon shows the dock is connected. If not, set to ALWAYS connected (Thunderbolt docks only).
Rescan for hardware changes in Device Manager.
Open the Graphics control panel. Check if the monitor is detected. Set to display if detected.
Power off and power on the monitor to check if it works.
Disable the following option and see if the issue still occurs.
Option

Step 3. Uninstall Thundebolt.
- Enter device manager, right click the Thunderbolt controller and select "uninstall"
- If prompted to uninstall drivers associated with the device, click yes and continue.
- Restart the device.
- Don't check for updates just yet.
- Enter the BIOS and check Thunderbolt settings.
- If enabled this time, enter Windows and check for updates, or leave it be if all is working.


Step 4. Reset docking station.

Check if the Wavelink has it's own reset function.  Disconnect all peripherals and perform the reset of the Wavelink.
