Dell Inspiron 14z :: Not Recognizing AC Adapter
Dec 6, 2014
Yesterday, my laptop stopped recognizing the ac adapter. It's been functioning fine until now. Now, it will not charge the battery and I can only use my computer with the cord. I purchased in late 2011 or early 2012.
Have read other dell model posts that suggest replacing the adapter, battery, updating BIOS, etc. Haven't seen anything related to my model.

Every time I turn on my Dell Inspiron N5010 laptop, I get the following message:
"The AC adapter wattage and type cannot be determined. The battery may not charge. The system will adjust the performance to match the power available. Please connect a Dell 65W AC adapter or greater for the best system performance."
I don't know why I am getting this message since:
- I am using the 65W Dell AC adapter that came with the laptop- The adapter is charging the battery properly- The green light on the adapter stays on all the time when in use- The port connection is fine
So, other than this annoying error message, everything seems to be working fine. Should I just ignore it ? If not, what else do you recommend I do ?

My Inspiron 11 (3000 Series) is not recogning its own battery. its not even turning on unless I have it plugged in (I checked it on two separate cords). I've checked it in the utility boot, and the battery is registered as unrecognized.

Inspiron N7110 . Wouldn't boot in to regular windows. I booted in to safe mode and tried to run chkdsk in system mechanic. it only got to about 20% and hung up. Now it won't boot at all. It isn't recognizing the hard drive. Is there a way to have the bios look for the hard drive? Running win7 64bit

I own a Dell Inspiron N5010. I am having a problem with the mouse, both the touchpad, and when I plug an external mouse in (although the problem seems to occur with somewhat less frequency when I am using the external mouse). The computer is having trouble recognizing mouse clicks. Sometimes it recognizes them properly, sometimes it responds to left clicks as if they were right clicks, and sometimes it does not respond to them at all. The problem seems to be worse when I am using a web browser, but it occurs consistently.

an Inspiron 1150 that had problems with the AC adapter (or so we thought) so he went out and bought a working motherboard brand new. I put it all back together and it wont boot.
The fans turn on for a few seconds and the hard drive clicks but i get nothing. m pretty sure it cant be anything with the motherboard since its brand new. I also tried reseating the ram, removing the ram completely, reseating the CPU, unplugging the touchpad, using an external monitor but all i get is nothing.

Wondering if anyone else is having this problem with Dell.
I bought an Inspiron 1500 14 months ago. Early on I noted that the adapter dell sent would sometimes slip out if the laptop was touched.
Then at 6 moths I started getting a message on power up -AC adapter wattage & type cannot be determined.- 2 weeks later the battery was drained and the system wouldn't recharge it .....

I've had a Dell Inspiron 15 3521 since May 2013; it has been updated to Windows 8.1, 4GB RAM, etc. It's been a great laptop in all honesty.
However, in the last few weeks, I've had some issues with the laptop booting up. Originally, it would turn on, but then stick with a black screen (no other sounds of the computer starting up), and then beep 7 times. Per another forum post I read, that's indicative of a Processor Failure.
In this case, I'd remove AC Power, the battery, give it about 15-20 seconds, then reconnect the charger. The laptop would turn back on, no problems. I'd end up popping the battery back in a little later, and it'd charge with no issues. This has been my fix in the meantime for the last month or so.
Now, I can't get my laptop to even register that it's connected to AC Power. It'll just stay black, and then beep 7 times in a row repeatedly. I've tried using another AC Adapter, in the case my adapter died, and no such luck.
What are my options? My laptop is no longer under warranty, though I do have my service tag.

I've had a Dell computer for about 7 years and had no problem with it so when I needed a laptop, I obviously went for Dell. I bought an Inspiron 1545 3 years ago and it was fine for the first 2 years and then the nightmare started. Just out of the blue, it starting showing a message "plugged in not charging" and I could initially use it on AC Power but it failed to charge the battery no matter what I did. I called Dell to report the problem but since the warranty was over, they were not really going to support. They suggested me buying a new charger or battery and although I had tried someone else's Dell charger and battery and it made no difference, I felt like I had no other choice.

I have a Dell Inspiron 1520 and my friend has a Latitude D820.
Tonight she accidentally plugged my power adapter into her laptop. A few hours later, she noticed that her laptop indicated that it wasn't plugged in, and that's when we realized that she had accidentally used my adapter instead of hers.
Now my adapter doesn't work at all. We've tried the adapter with both our laptops with different outlets with the same problem, so we know it's the adapter. The green light also doesn't come on when it's plugged in anymore.
Did plugging my adapter into her laptop somehow screw up my adapter, or could this just be a coincidence? Is there any way to fix the adapter or at least figure out what the problem is? And if I have to purchase a new adapter, do the universal ones they sell at retail electronics stores work OK? I would order one from Dell but I'm working on a project now and I don't have time to wait for it to ship.

I received my E6400. In short, I like it. It came with 1gb of Ram. So I ordered 4gb of Crucial (2x2gb) ddr2 6400 to put in it.
Well. It's only recognizing one stick of it. The Ram itself is not bad. I've verified this by placing each stick in individually and I get no errors. Would there be any reason the computer would not be recognizing that second stick that isn't hardware?
The bios says the second slot is empty. Which either means that for some reason the software isn't recognizing the ram or the second slot itself is bad?
Ah...specs.
Started out with XP. It did the same thing. only 1 stick was recognized.
I've installed Vista Home Premium 64-bit.
T9800
Bluetooth upgrade was user installed.
What other system info do you need?

Iv read a few posts online saying that Dell blocks people from using non dell power adapters on their machines by not letting those adapters charge the battery.
My issue is, I need a new power adapter AND a new battery.
I really don't wanna fork over $130 for a new 6 cell battery, Especially because on the dell site the reviewers themselves had given it a bad review saying the battery usually dies in a year or less.
That and my Budget is about $100 for both battery and adapter.
I need to find a battery that works, and an adapter that will actually charge the battery and keep the notebook charged.
This is basically a question out for Dell Inspiron users that have had this same issue and have had to replace the battery or the charger. If you guys could tell me what has worked for you and what has not, that way I can at least narrow down my options on chargers and batteries.
Id like to find a charger with the same volts as the dell charger has If I can't find a non official charger that works, could you guys at least point me to a less expensive site where I could buy the dell power adapter.
I would much rather just buy a charger and battery outside dell though because their products are by no means high quality and are in fact well overpriced.

I have a problem with my Inspiron6400. The AC-adapter powers and runs the system correctly but does not charge the battery. In the BIOS set up I read "unknown AC adapter installed", which of course isn't the case: it is the original one that came with the laptop. I updated the BIOS to the latest version (A17) but this doesn't solve the problem.

I continuously have to reset my wireless network adapter on my Inspiron 17R. This normally happens about 5-10 minutes after startup.

My laptop model is Inspiron N5110, I bought it about 3 years ago.
Last week, there has been some power fluctuations and immediately the infamous message saying "AC power adapter cannot be determined" appeared, and the system is very slow right now even when the battery isn't inserted.
I tried uninstalling & reinstalling the "Microsoft ACPI Complaint Control Method Battery" and it did't work either.
What is strange is that one minute I can charge the battery with the same AC adapter & the system operates just fine, the next this infuriating message appears & hell breaks loose.

I have had this laptop for 2 years and after the first year I had to replace both battery and adapter.
The first generic adapter I got was fine until the cable split (my fault as I was wrapping the cord around the brick).
I got the second generic from the same place I got the first.
I bought the new one last month and since then I have sporadically received a message that the adapter wasn't OEM and that it wouldn't charge the battery.
It would get back to charging after a reboot or stand by.
Now I have tried everything but it won't get back to charging the battery.
I did a search here and found others with the same problem (different dell laptops) solving the issue by flashing the bios.
Can anybody point me to the correct file I should download for my laptop as well as explain what should be done to flash the bios

I have never had an issue with using the SD slot on the front on the laptop, until now. I extracted the SD spacer to insert an adapter with micro sd and the adapter will not fully mount into the slot. I have tried just a regular SD card with the same results. The adapter has no problem being inserted or popped out. I don't see anything 'jamming' it or a foreign object in the slot, as much as I can see in the little spot.

I have a 2 year old Inspirion 1545. The battery and adapter simultaneously died on me, so I bought new ones and can't for the life of me get the adapter to behave. One day,it will work,then the next day,nothing. I keep getting an error code saying that I need a65w adapter ,which the new one is. I have updated the BIOS and have done all of the other troubleshooting that I can find.

I have a dell inspiron m5030, which is out of warranty, and unfortunately it wont charge the battery, or boot from the ac adapter and since the battery is dead I can no longer turn on the laptop. I already sent this laptop back to dell 2 prior times when my warrenty was still active due to the 7 beeps and I think that the mother board is going bad for the 3rd time.

My Inspiron N4010 will not power on with the AC adapter or battery attached. I removed the AC adapter and battery then removed the memory modules.
I re-inserted the battery and the AC adapter but it sill does not do anything. When I plug in the power adapter the lights on the front of the laptop light up.

I just reinstalled windows 7 on dell inspiron 1525 and the wireless adapter isn't picking up any connections. When i troubleshoot the error it says 'turn wireless capability on' the switch on the laptop is on but the light isnt showing up on the laptop.
I checked device manager and there is dell wireless mini-card and it says it is working properly.
