Why is Dell XPS battery not charging?

I have a Dell XPS 15 and gotten an alert before starting the laptop that reads "Alert! The AC power adapter wattage and type cannot be determined. The battery may not be charge. The system will adjust the performance to match the power available. Note: This warning can be disabled in BIOS setup."

Since this appear the battery won't charge but laptop will be on if the charger is plugged in. It's not the battery nor charger the problem because it's still fairly new laptop. I did used a 90w charger which probably cause the problem because the laptop uses a 130w charger. However I have both and its still given me issue. Any suggestions to fix problem?

We have two of these with this problem. Interestingly, they both have i7 processors. We have a bunch of these with i5 and none of these have charging problems. Any luck with this? We are still searching for an answer.

For me the solution was similar to the solution found at dell's support website - https://www.dell.com/community/General/D.... The last post mentioned that a prong needed be adjusted within the charging hole of the laptop. I saw a prong in my XPS 15 was sort of bent so I adjusted it, plugged the charging adapter in and it started charging finally.

Hey guys I just got my Dell Laptop less than 30 days again I was having the same Alert message about Power dapter and Apparently I was not pushing the plug all the way in to the laptop connection. I was only pushing it in half way thru. Just realized that and pushed it in all the way and now im charging back up to normal. So just FYI, make sure your plugging it all the way you just never know that could be the problem. Hope this helps, thanks!

This didn't help anyone. You are the only person on earth that would only push the power plug half way in.

2 things here.

"Alert! The AC power adapter wattage and type cannot be determined. " really does mean something is not right.

If you tried 2 separate genuine dell chargers, and both give you this error, then there maybe something else wrong. Enter the BIOS, and look at the battery/power section to see if tells you more. I have seen the power jack itself get messed up, and that may be the cause. Plugging in a 90W will charge slowly, but will not give a cannot determine message.

I am having the same problem, actually now for like fifth time already. I own my xps 9560, i7 for like 2-3 years. Dell is absolutely silent about this, so your only chance are forums like this (or Pro-Support, see below). I checked a lot of times and I am 100% sure it was never caused by wrong adapter, bent pin, worn jack, loose socket, bad battery or some software nor bios issue etc. People that are giving advice to check these things must be assuming you are a complete retard or maybe they fixed few computers like this and then they think they know everything. Let me tell you that about this particular issue, they know nothing. Nobody has so far solved this one and it is a very frustrating one. It seems to be not so rare either.

First time I let the Dell service solve it (pro support). After some initial remote troubleshooting to exclude the case you are an idiot who cannot use google, a technician came with a motherboard and replaced it. It worked for half a day until it happened again. Strangely enough, when I was messing with the computer myself (like unplugging/plugging battery at random times), I (very rarely) managed to charge it to full. However, it never stayed for long. So they took it, send it somewhere (Poland?), where another technician exchanged the power socket with AC cable + motherboard. Since then, it worked fine for a long time, although very occasionally, the battery stopped to charge, but only temporarily. What I observed is that the issue is much more likely to trigger when you don’t plug the adapter into the wall socket directly, but use whatever kind of an extension cord or fork. So it is likely to be caused by some fluctuations in the input power. Although one would think that the adapter takes care of that, it seems it doesn’t. To support this, I also observed there is relatively high probability of the issue to trigger when you plug the computer into a socket on a train and then they switch the power off and on again (at stations etc.). So it seems something gets (progressively?) damaged inside computer, but it is unclear what. Sometimes I managed to resolve the issue by disconnecting the adapter in the middle, reconnecting the wire to the computer’s socket and connecting the middle again (or some permutations of that). This time however, it does not work anymore and I am now running the machine without battery (it won’t start with depleted battery, but starts without it - makes sense). I already tried to replace the socket and AC cable myself, but it did not help.

In conclusion, it seems that the only reliable fix is to replace the AC cable + motherboard at the same time (and then stay away from extension cords and train sockets), but since I tried this solution only once, I can’t even guarantee that. The motherboard is not a cheap part and obviously lot of screwing to change, so you will probably be better with extending your warranty and letting them repair it.

I actually fixed mine 3 months ago. Gave it to a repair shop to do it for me. Cost me 240£, but they fixed it. Voltage distribution unit had burned down, so they changed it. Now both charger and touch screen is working back as normal. It is complicated motherboard repair that costs a lot of money, but it was worth it keeping in mind how much a new laptop this spec would cost me.

I suggest to bring it to professional third party service where they can fix motherboards. I was messing with it before myself, no luck with some bent pins in RAM. So I don't suggest to do it yourself if you are not professional.

The problem may be that the motherboard power section is not recognizing either power adapter correctly. You can check the BIOS settings, if there is a problem on the motherboard the power adapter will show up as 1 watt instead of 60 or 90 watt. The built in diagnostics might give you more information. You should also check the power connector, it should not move; if it does it could be loose enough that the contacts don't match up.

The laptop generally needs 60 watts of power to run all the installed devices. If you have a dock, it requires an additional 20 -30 watts to run the devices in the dock. Plugging a 90 watt power adapter into the dock will result in one or more devices connected through the dock to not work, most cases it is the external video that does not work. Plugging a 130 watt power adapter to the laptop will not hurt the laptop as the laptop will only draw the power it needs to operate.

Replace the mother board. If the power adapter shows as 1 Watt in BIOS, then the mother board is the problem.

My XPS 9560 stopped recognizing the power adapter. I tried changing the DC jack (twice), flashing the BIOS, removing battery from the system (so Windows would reinstall). Nothing worked. My battery got to 0 % and when I removed the battery, it would boot and run fine, but having no battery is frustrating. Finally, I saw a thread where someone said you could charge the laptop through the USB C port (but slow, since power is low). I saw a 90 W USB-C on Amazon and got it. It charged the battery in a couple hours while the computer was running. It may not be the full 130 W, but it’s very usable and charges fast enough. Here’s the Amazon link if you want to check into it:

I have the same model and this issue began last week for me. It appears that this DC jack is very faulty which is upsetting because this laptop was $1800.... I am able to get it to charge after messing around with the charger but its frustrating. I wish DELL would have a recall or something of the nature for these laptops because it is unfair.

I'm having the exact same problem and went through the exact same steps to try and fix it as you did. Buying that USB-C charger ASAP, thank you so much for this (hopefully) temporary solution. I hope it'll work as it did for you!

Hey David did it work?

I made a quick video showing how I fixed the problem on my XPS 15 9550. I have two Dell 130w power adapters and the center pin was fine on both. The problem on mine was the DC Jack was moving when I would plug the power cable in. Hope this helps someone else who stumbles upon this forum.
