XPS 13 9350 not charging with USB-C or adapter

When you try a reset follow this procedure. Disconnect the battery. Then unplug the adapter. Now press and hold the power button for 30 seconds. Now reconnect everything and try again. If that does not work then run system diagnostics. Start the system and at the Dell splash screen start tapping F12. Run full diagnostics. Also check the battery and adapter to be sure they are detected in the BIOS. At the Dell splash screen start tapping F2. If battery health still is excellent and the adapter is detected as a Dell adapter then only 2 possibilities remain. The pin on the DC power jack is bent or broken and the jack needs to be replaced, or the problem lies on the motherboard. In which case the motherboard will need replacement.

The following post might help as well.

Thanks for your reply @JOcean, but unfortunately, it makes me feel like you didn't read my question. I've tried what you said, as I listed in my question.

And if the pin is bent or broken, then I'm assuming charging via USB-C would still work? That's exactly what I'm asking: am I right in assuming it's the motherboard?

Thank you for your message. Did this issue start after any BIOS update or BIOS changes?

Is the battery level the same in Dell Command, battery icon in the notification bar & in BIOS?

If you press the battery charge stats button does it indicate that the battery charge is low?

Have you tried to drain the battery completely & check if the system charges after that?

For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Dell-Sreejith R) & send a private message with the service tag, registered name & email address.

What is a Dell Service Tag and how do I locate it?

Sorry for the confusion and my misunderstanding. Just trying to cover all the bases before stating with confidence that the motherboard is the source of the problem. Please follow the steps that SreejithR has suggested and he will be able to pinpoint the cause.

This did not start after a BIOS update or change. Though I have tried updating my BIOS in hopes of solving the issue. It did not.

All tools (BIOS, Windows, Dell Command) indicate the same battery percentage. The LEDs on the side of the laptop indicate about the same (2 of them light up).

I will try draining the battery completely and report back.

Unfortunately, I only reached 30%.

This is what I did:

• unplugged both USB-C and adapter
• waited for laptop to shut down automatically at about 5%
• rebooted and entered BIOS
• waited for battery to drop to 0% and have laptop stop
• pressed the powerbutton 2 times to make laptop try to boot again (didn't work of course)
• plugged in adapter, waited for a while and rebooted

Dell Command | Power Management now says "30% available, plugged in, not charging". Though I've seen it sometimes switches to charging for a few seconds and then back to not charging. But I'm thinking that might be because it's using power when not charging, then notices it can charge, charges to 30% and then stops charging again.

So we're probably looking at a motherboard replacement here?

I'm using the original AC adapter.

As I'm also having the issue with USB-C, I assume it's the motherboard? Or does USB-C somehow use the DC-in cable? From what I could see, I think the USB-C is directly connected to the motherboard.

I'll send you the service tag and other requested details.

This does seem to be an issue either with the motherboard or the DC-in cable.

Are you using the original AC adapter shipped with the computer?

Please share the service tag along with the registered name & email address on a private message. I will assist you as per the warranty & get the parts replaced. 

For anyone coming here in search of a solution: I did not fix it.

I summed up above what I tried. Nothing worked. I finally ordered a new DC jack and replaced it. This did not fix it unfortunately. Another possible solution could be to replace the motherboard. But new motherboards for the XPS-13 come at around €700, which is not a cost I'm willing to make if I'm not sure it will be fixed.

I have found that putting the adapter in for a long time will "trick" the system into thinking it's at 100%, but it isn't really. The battery will still only get about 1 hour of usage. So even though it says 100%, it's still actually at around 30%. This can also be seen, because it drops rapidly.

This is very unfortunate, because I really like my XPS 13 otherwise. Alas, no fix here.

I bought 4 XPS here last year, and two are doing the same thing. All three USB-c adapters will not charge the computers. I purchased new charging cords from Dell, but that did not fix the issue. Now they are all out of warranty. I am completely done giving Dell my money. They never last

I purchased Dell XPS 13 along with 2 Dell Docking Stations (more like powered hubs as there's no real docking). From day 1, I would get a message stating that the XPS was not charging and that I should get a "DELL" product to charge my laptop. BOTH Dell hubs from DAY 1 gave me this message. My XPS was still getting sufficient power, so I  ignored the message thinking it was a glitch. (like Dell worked with a third party for the accessories, but forgot to certify them as "DELL") 2 years later, the Dell hubs no longer power my XPS. Both work to power and link external display, mouse, keyboard, speakers, but neither can power my laptop sufficiently. I purchased a separate (non-Dell) USB-c charger and it works great to charge my laptop. There's definitely a compatibility problem with the XPS and Dell docking stations/hubs.
