Update = Dell chat agents setup service to exchange the dock.
Hello,   since a few days sometimes in the morning I find my laptop shut down. Laptop is connected to the WD19TBS docking station. It happened again this morning and at reboot I had a BIOS warning about the connected power supply which couldn't deliver enough power for optimal performance and had crackling noise from the docking station. I called the support, describing the problem, and they told me that Precision 5550 requires a lot of power (210W) and that WD19TBS is not fully compatible with the system as the maximum power is 180W. It was suggested to use a WD19DC or WD19DCS, but also this model is not fully compatible or use the power supply but then I can't use dual display. Note that I have been using this docking station for about 2 years and I require dual display and that WD19TBS is an official DELL accessory. I have disconnected the docking station for safety reasons, as the noise increased. Which docking station should I use? How can I get a replacement as the warranty expires in 2024?
