[NAME] 17  “Inspiron 15 3000” is not a laptop model. That is an entire laptop series. But the current Inspiron 15 3000 Series model on sale in the Dell US store appears to be the 3510. If that is the model you are looking at, then no it will not work with that work because it does not have a USB-C port, and the WD19 dock family models require not only a USB-C port, but one that supports video output and system charging, both of which are optional features and therefore are not available even on all systems that actually have a USB-C port. And for FULL functionality, the WD19TB requires a system that supports Thunderbolt. Lastly, if you expect to be able to use the dock’s Power button to control the system, support for that has at least historically NOT been implemented on Inspiron and Alienware systems, but rather only on Dell’s business-oriented product lines such as Latitude, Vostro, XPS, and Precision. If you want to find a better match for that dock, I would suggest looking at the Vostro lineup, and you will probably have to step up at least to the 5000 Series. The Vostro 15 5510 for example comes with a suitable USB-C port that gets upgraded to Thunderbolt if you order the system with an i7 processor.
I recently bought the "Dell WD 19TBS Thunderbolt Dock" and I wonder if this dock can be used with a Inspiron 15 3000 laptop? So I am considering to buy a new laptop Inspiron 15 3000, but I would only do this if the WD 19TBS dock, which I already have, is compatible with this laptop. I was already searching on the Dell website, but didn't find any relevant info. Any hints and advices would be much appreciated, Thank you very much! with best regards P
