"AC Power Adapter Not Determined" , and Power Adapter Won't Work

  • Problem
  • Updated 3 months ago
My computer recently displayed a "AC Power Adapter is not determined." message. I did not change anything, all I did was go to a friend's house and plug it in and it appeared there. Taking out battery and holding down power for 10 sec won't work. It appears everytime, and my battery is slowly being drained. Help!

Hi, bradr.

It sounds like you may have a problem with the data pin on the ac adapter. I can see about replacing it for you. I would just need your service tag. You can email it to me if you like at william_bivin@nospamdell.com.

No, it is not the data pin. It's not bent. I had a very annoying session with your very annoying technical support people that ended up with me buying a new power adapter for 100 dollars. ONE HUNDRED DOLLARS. Come on, that's retarded and expensive. Just because my warranty doesn't cover anymore doesn't mean you need to be outrageously expensive.

So, you bought an ac adapter that did not resolve your technical issue at the recommendation of tech support? I believe you would be entitled to a refund for that order. I can get that processed for you if you want to email me your service tag or that order number. I could also look at when your warranty expired, and any logged contacts we have to see if there is any way I can help you without your having to foot the bill. Not that I am guaranteeing I can get the motherboard replaced out of warranty, but it's worth looking into. At the very least, you should be fully credited for the purchase of the adapter.

Naw, I bought a refurbished and it works now. I have written about it on my blog, and Bill, if I am not mistaken, you have replied:

I bought a inspiron 1501 about 14 months ago. It has been a nightmare. The ac adapter broke. I called and they sent a new one. Great! Then the LCD screen failed. They sent me a new one. It works. Then the AC adapter broke again and would not charge my battery or power up. Dell sent be a new battery. Still no luck. Dell decides to send another AC adapter which would not charge the battery so I just have been plugging my laptop directly into the wall. Guess what..the new AC adapter now does not work. I can't power on my computer. I was sold a complete piece of you know what! I called support again...always in India and they informed me that my warranty was up. The warranty parts that were shipped to me do not work or fail soon after I receive them. I have probably spent 20 hours on the phone with tech support trying to decipher broken English for nothing. Is there anyone at Dell who actually cares about the customer anymore? I run a business and if I pulled this stuff on one of my customers I would no longer be in business, I own 4 Dell computers. I will not be buying a Dell product ever again! I simply cannot believe how far the customer service and product has fallen over the past decade.

Dell Bill - Can you point me in the direction of anyone at Dell who could help me?

Thanks,

Tim

Hi,

What is the problem if the message AC power adaptor is not determined comes up, but you can still have AC power. The battery is not getting charged only. It not the battery cause I have two. And why would the AC power be ON, if there was something wrong with the adaptor? Help, what is the problem?

Thanks

Bill_B has helped me with this problem. Dell Customer Service is not as prompt as I would like, but realistically and hopefully, everything will work out. All it takes is a little patience (it took almost 6 business days to get things almost resolved). Faith in Dell restored (as long as I get my adapter soon)

Hello Dell. I am having the same problem regarding getting the "AC power adapter cannot be determined mesage". I had this problem before and I was sent a new power cord but to my dismay, the problem is reoccuring now. I believe there is a problem with the motherboard since this will be the second power cord that has stopped working. I wish my motherboard would have been tested the first time this problam occured because my warrenty is close to being up if not already (will be checking this out soon). By the way, almost every time I plug in my power cord a spark shoots out from the metal prongs, that is when it actually works. The power cord used to "kick" back in and resume normal powering but now it has given up. I have about 2 hours worth of battery left and am hoping I get help before it runs out. Is this where I make a post to inquire help from Dell? My apologies if this isn't the correct place.

By the way, I have a Vostro 1000 (XP) and it was bought about a year ago.

If you are getting sparks when you plug in your ac adapter, you definitely need to report that to tech support. If your warranty is close to expiring, I urge you to call, email or chat with support as soon as possible.

Your warranty was recently expired. I sent an ac adapter. Please consider this a one time warranty exception. Thanks for your patience.

I have the same problem, what's the easiest way to solve this problem? Do I need to get a new AC adapter? I've only had my computer for 3 months, this is very frustrating.

I'm in the exact same situation. It really, really sucks. Dell Inspiron 9400 with an adapter that refuses to charge the battery. The laptop's probably out of warranty by only a few months. It's disheartening, really..:(

Can you post your service tag, please? I will have a look at it, and see if I can manage to get approval for a warranty exception.

Sorry, but I can't dispatch outside of the US and Canada. Your warranty expired back in March, so I doubt Dell EMEA will do a warranty excpetion. Your best bet is to buy an ac adapter from Dell Spare Parts in Ireland, or from another supplier of Dell adapters online. You can probably beat Dell's price, but with Dell you get an abbreviated warranty through us instead of whatever the vendor offers.

I have the same problem with a Insp. 1501. I think my warranty is expired. I bought the computer in March 07. My service tag is 3BF1MC1. Bill, could you please advise me as to my options?

Thanks.

Your warranty is expired, but I will request a warranty exception for you. Is your shipping address still the one that starts with 937-5 West XXXXXXXX?

My Address is 6051 BaXXX Huntington WV. It should be updated on the Dell website.

Hmm. OK. I pulled your yahoo email address from your service tag records on a previous contact. I will email you. Please reply to that with your current shipping address at your earliest convenience.

I have been so frustrated with this same situation. My adapter has been replaced twice, they just seem to burn out. Now I am out of warranty and without an adapter.
This seems to be a common problem with the inspirons.
Is there a way to resolve this?
Thanks so much

The only resolution is an out of warranty exception dispatch, which would depend pretty much on how long ago your warranty expired. Or you could find a new ac adapter pretty cheap out on the web or from Dell Spare Parts.

I have the same problem with my 9300, I had the mother board replaced twice and 3 new power supplies and the power supplies keep burning out. I run my own voice over biz, so im always on my laptop but my power supply works 75% of the time now. My warranty expired a year ago, is there anything I can do to prevent my power supplies from burning out?

Terry,
Without knowing exactly what you have going on, or where you are located, it is a little hard to surmize exactly what the problem is. I'll assume you are using a Dell OEM adapter that is of sufficient wattage. Your AC power is not nearly as well regulated as you might think. Some areas of the country are far better though than others. If you have unusually large power swings on your line, they could definitely cause you trouble. Sometimes you can notice them in your lighting.

I don't guarantee this to be your cure, but you may want to try looking at Tripp Lite's webpage. Here is a direct link to their better surge suppressors.

http://www.tripplite.com/EN/products/...

I'm not talking about a simple power strip here.. These are quality products and will protect your equipment from anything coming down your power line. I use an Isobar 4 to protect my equipment.

As I said, this is just a wild shot in the dark not knowing your specific circumstances. You may want to investigate a bit further before deciding to invest in one of these products. Good luck, Rich

PS. The ultimate resolution? Having the knowledge to never purchase another product with a proprietary power scheme. :)

I have a dell inspiron 9300 service tag# 5r4wp81. My computer doesn't recognize my power cord, but it only works when the power cord is plugged in. The battery and cord are both brand new, The battery shows that it is fully charged, but it will not stay powered up unless the cord is plugged in. What can I do to have this problem fixed. I own a business and have purchased atleast 15 dell computers. Any help would b e appreciated.

I just reported a similar problem to Dell. Inspiron 6000 under warranty another six weeks or so. New battery being sent out to make a first pass at problem solving. However, I have gotten the "ac adaptor not determined" on and off over the last 2-1/2 years. Now, power meter is stuck at 97% and "charging" but can't run off battery. Tech rep said if new battery does not resolve issue then motherboard would be replaced. So, after reading all these messages I am now wondering if the adapter should also be replaced? In system devices the adapter is displayed as "Microsoft AC Adapter" but it is a Dell original 65W adapter. Service tag DHT6191 if you are out there Dell-Bill.

I have this same problem, "AC power adapter could not be determined" Is there anything that can be done to fix it without spending hundreds of dollars? My service tag number is 8F200F1. I would appreciate any help.

i also have this same issue i contacted Dell and the service rep (Divya_178142) wasnt helpful at all just kept saying i must have had a powersurge and it fried the adapter but i kept telling her it was impossible since its connected to a very good surge protecter and i have another computer attached to which is perfectly fine. i purchased the laptop around end of jan and it has been giving me the AC adapter not recognized for about 4 months but i would unplug it and replug it and it would go away and start charging my battery but now it doesnt even do that. my service tag is D8PXCF1 DellBill if your still out there.

I have the same problem on a d630. I get the message: AC power adapter type cannot be determined and then the battery won't charge. To make matters worse, the cpu clock speed drops to 800 MHz (from 1800MHz). The computer becomes really painful to use.

This is all a scam by Dell to ensure you only buy their expensive adapters instead of cheap universal ones or cheap alternatives. The signal serves no purpose that benefits YOU, the end-user, the customer, the person paying money to Dell for their goods. There is no reason to drop the clock frequency, dim the screen or stop the battery charging. It simply cannot benefit you to do that, it certainly doesn't "protect" you or the machine. Any power supply that outputs 19.5V at the same or higher wattage (current) as the original would work perfectly if not for the lack of signal coming from it. End result, you buy an original from Dell and the big-wigs in Dell buy another holiday home in the Bahamas for a few million.

By the way, a lower voltage or wattage power supply does no harm; the laptop will simply refuse to function.

A higher voltage will potentially damage the laptop (I've tried it and it plays havoc, causing the laptop screen to die whilst voltage too high - the PWM inverter board supplying juice to the LCD's tubes goes into shutdown). The Dell signal nonsense will not protect against overvoltage, the true killer of motherboards (although they can usually be fixed - I've fixed a few). If you use a universal set to a voltage way higher than it should be, the lack of signal from the adapter won't protect the laptop.

A higher current does no harm whatsoever. Any electrical device only uses as much current as it needs. The exception is a fluorescent tube which requires a ballast transformer to act as a current-limiter, otherwise the low resistance plasma in the tube will pass as much current as it possibly can, creating a runaway current drawing situation. TVs, laptops, heaters, kettles, computers, stereos - all electronic goods - will use what they require. If you offer them more, all the better - they have plenty if needed!

I had the same problem. I was about to buy a new powersupply. Then I saw a post about the plug not seating all the way. Just enough to power the computer, but not deep enough to connect to the charging circuits. Well, low and behold, there was debris in my power plug. Some random plasitc had become lodged in there and prevented the plug from fully seating. Cleared it out with a paperclip, and it works fine. BTW: the plastic did not come from the computer, it was a different color.

I have the same problem as the people above. I started last time by buying a new adapter, and it worked for only two months, but things went back to the "abnormal normality". It is getting drained now I am so frustrated. Please help.
