9570 plugged in, not charging, replaced socket, but will charge still through USB C.

Run diagnostics (tap F12 immediately at boot) and watch for the battery and adapter status. Usually 3 things prevent charging, a bad adapter, a bad battery, or bad DC jack. If none of those tests bad then it could be the MB charging circuit associated with the DC jack.

Same story, is detecting the charger, says it's charging, but it isn't actually charging. Only the USB C will charge it now. 

I did inspect the surface mount components around the connector and there's no visible damage, missing surface mount components or debris.

Changed the jack twice, have two chargers at my disposal, so I guess something on the board has failed permanently.  At least I can still charge it by USB C, but it's a shame as I probably go back to MS Surface products again at the next upgrade cycle. 

Thanks anyway. 

Thanks, I will give it a go tomorrow evening and report back on the results. 

Given the frequency in which I've had to buy replacement chargers due to using it on my actual lap all day and the DC connector eventually failing, perhaps USBC charging is a blessing in disguise as I'm then not throwing away an entire charger and can just replace the cable if/when it fails.  

The only other thing I can suggest is a reset. Disconnect the battery and the adapter. Press and hold down the power button for 30 seconds then reconnect it all again. If that does not help then a MB may be the next step.

. On my 3rd adaptor and 2nd charging jack, then it refused to charge again. I got yet another charging jack and it made no difference.  I suspect the charging circuit on the mobo has failed, although I could see no visible damage when inspecting the motherboard.  

I also charged it via USB C with a 3rd party 100w USBC charger. This helped it with a slow charge while in use, but it also restricted the CPU to 2.8ghz no matter how full the battery was, and charging took a very long time.

I resolved it by purchasing a 130w USBC charger on Amazon for £37.99. It wasn't made by dell but it is compatible and states that it works on dell XPS laptops. It works now and charges at full speed and clocks the CPU back up to 3.8ghz turbo, so I'm back to the same condition I was previously in with a fully working charger and functionality, albeit through USBC.

Dell must be doing something funky with the USB C ports as they are only rated up to 100w, but dell use them at 130w with their USBC docks. 

The USBC connector would be a nightmare to replace, and I also don't want the same failure of adaptor, so I am going to put a heat shrink sleeve on the USB C connecter to give it more support and rigidity. 

I had thought about using a USBC extender so I could throw away a broken extender in future without having to plug the charger directly into the laptop, but I don't believe there are yet any USBC extension cables rated for 130w, but it is due to be implemented in the next version of USBC, which currently sits at 3.1 with the 100w power delivery limit. Future versions will support up to 240w, and so I will keep looking until one is available.

Could you drop the link to that charger here? Been having the same problem for about 2 years as well. Been limping it along with a slowly charging 3rd party charger. :(

@JOcean​ Can you help me out please? I have Dell xps 9570. My dell xps 9570 had undergone undervolting process. I was successful but now, My laptop would stop charging suddenly. I had to repair my Charging IC for 3 times. The repair man said that there is a 19.5 watt IC that is causing Problem and needs replacement. Can you tell me how to fix it? 

I followed this article on Reddit for Undervolting: https://www.reddit.com/r/Dell/comments/fzv599/xps_7590_160_uefi_unlock_undervolting_and_remove/

@dellxps9571​ Dell does not issue circuit diagrams for their systems. If it is an IC then a repair shop would be your best bet. Or if the problem keeps reoccurring possibly a system board replacement may be the best solution.

@JOcean​ Thanks for the reply. Let me tell you when It started to happen. When I purchased this Laptop, I installed the latest BIOS and this Laptop had a problem that It would stick at 0.79ghz. 

Somebody on Reddit told me to undervolt it so I did it and the problem went away. After few months, I accidently reset the BIOS and the undervolting went away. I then upgraded my Windows to the Latest version through windows update and to my surprise, the 0.79ghz Bug went away without undervolting.

My Laptop became very fast and It would load anything really fast. I was surprised but I did not know what happened to my Laptop. But after few weeks, my Laptop 19v IC was damaged. So the repair man told me to replace it and I did it. 

But I kept running it without undervolting and It keeps damaging my 19v IC and my laptop would not charge.

This is the forth time that my Laptop has stopped charging because of the same problem that is 19v shorting. All this happened After I downloaded the windows update files on my windows. 

Is there any solution to this?
