Every morning, the same behavior happens.
I wake my computer from sleep. At the Window login prompt, I connect the WD15 with my laptop (Dell Latitute 5580). The connection establishes (the attached monitor turn on and works). After 5-10 seconds, the WD15 shuts down on it own. The white led on the dock (and on the cable) shuts off. I have to disconnect the power of the dock, disconnect the dock from the laptop and finally reconnect the power to turn on the dock. When the white led are back, I reconnect the WD15 to my laptop and now, the connection is stable (does not disconnect) and everything works.
Is this a known issue ? How can I fix this ?
I'd suggest you run the Guide Me option in your Dell Product Support page to install latest Chipset drivers on your computer. Please follow instructions to run Guide Me option in the link below.
