WD 15 dock station charging
Hello, I have g5 15 5587 pc and wd15 docking station and this is pretty new. When I set it with my PC's AC adaptor(180 w), the dock works very well for all USB, VGA, and HDMI, etc. But also I want to use it for charging my pc with the same type-c cable. This pc is newer than the dock station so I can't see it in the suitability list for wd15. but it should work technically. when I set type-c to pc, pc realize that type c carry power but it won't charge. It says that type c input is not suitable for power input. but when I look next to the type c input there is a lightning bolt which means that there is the power input. I think I need to install a driver but I couldn't find it. Can you help me? I have to solve this problem.

@berkans Dell's Inspiron G Series systems do not support charging over USB-C. And this is not a driver issue because you can of course charge systems while they are completely shut down, in which case no drivers are active. The lightning bolt you are looking at means that the port supports Thunderbolt 3. That does not automatically mean that it supports system charging. In terms of WHY those systems don't support charging over USB-C, the USB PD standard currently maxes out at 100W. Dell did something proprietary to stretch that out to 130W on some of their systems and docks, but they have not implemented that on any Inspiron systems to my knowledge. And even 130W would still only be about 72% of the power your system is designed to have available, so using your system from that type of power source would result in performance throttling. So maybe Dell decided that supporting USB-C charging at reduced performance wasn't worth the customer support calls or the complaints/negative reviews from people who didn't understand why their system was slow when powered over USB-C. And actually even 130W from the WD15 is only possible when the WD15 itself has a 180W adapter plugged into it. The WD15 was also sold with a 130W adapter, and in that case it can only supply 90W to the attached system.
But regardless of what power adapter you have with the WD15, you won't be able to power your system over USB-C.

@jphughan hello and thanks for your answer, Your answer is very explanatory. However, what I do not understand is that this choice should not be presented to us, I think that the user is presented in two options with a simple explanation and the desired choice is selected. For me, the less I reduce these connection cables, the better, I bought this product with this plan. If I could only use the device without using the charging feature, it would be enough for me, but this time I would have to host two separate adapters, so it would be more logical to use a standard dock compared to the wd15. Well, because I trust your information, I would like to ask you: Is there any chance I can turn on this feature of my computer? I would appreciate it if you could help me. If we do not have a software chance, do I have a chance to use this dock without connecting an adapter as the 2nd solution, or as a 3rd solution, do I have a cable apparatus that turns the end of 1 adapter into 2 separate outputs so that I can connect one to the pc and one to the dock.

@berkans I understand your point about wanting a choice. Unfortunately, the real world reality is that many users when given a choice don't realize they are making a choice and therefore don't understand the impact. If Dell supported running the system from an undersized power source, then I guarantee you there would be people complaining about slow battery charging, low frame rates on games, etc. They wouldn't realize that they had made a choice to use an undersized power source. They would just say, "I'm using a Dell system with a Dell dock. It should work properly." And the reason I know that is what would happen is because I see that here all the time. People post complaints on this forum or negative reviews somewhere about problems that are the result of something they chose to do, or they'll complain that something doesn't work even though the documentation said it wouldn't work. Many users don't read manuals and don't pay attention to warning notifications. Some won't even look at those when they're having problems, and will instead just go straight to posting a negative review. So in that case, giving users more choices is not always a purely good thing. There are downsides to supporting reduced functionality levels because users won't always realize that they should expect reduced functionality based on what they've chosen to do.
You say that if you could use the WD15 without the charging feature, that would be enough for you. Well, you can do that. Just connect the WD15 and then your system's power adapter at the same time. That will not damage anything. Your system will take power from its own power adapter, and the rest of the WD15 will work as expected -- except that you might not be able to use the dock's Power button to control the system. That requires firmware support within the system, and Dell doesn't seem to have implemented that on their Inspiron systems. They still see docks as business products, so they focus on their business laptops (Latitude, Precision, XPS). But the displays, Ethernet port, USB ports, and audio jacks should all work.
I'm not sure what you mean about having to "host two separate adapters" and asking if a "standard dock" would be better than a WD15. But there is no chance of enabling your system to charge via USB-C. If it doesn't work now, then there's nothing you can reconfigure to make it start working. You can connect the dock without also connecting a power adapter, and the dock will work, but in that case you would be running your system on battery power.
And no, there is no adapter that you can use to separate the WD15's USB-C connection into two separate connectors for USB-C and power. That would not work because your system's power adapter connector would not know how to perform a USB PD negotiation with the WD15 to start drawing power from it, and the WD15 would not be able to supply enough power to run the system properly anyway.

thanks for your answers
1.when you wrote in your first message, when the computer is turned off, when I put the dedicator in the dock, the dock to the pc and the pc is turned off, unfortunately it did not charge.
2. When I plug it directly to the pc without plugging an adapter into the dock, usb etc. did not work.
now i'm looking for a different way for this i hope i can find it. thanks.
