Dell Latitude D620 :: AC Power Adapter Type Cannot Be Determined
Feb 3, 2013
I bought a new docking station to improve my workplace at home. Unfortunately I wasn't able to start a system because of warning during a booting sequence : "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge....etc". After that waring the only possible action is pressing F1 button to shutdown a system.I connect an AC adapter directly without a docking station, a system started properly.

I recently purchased a refurbished Dell Latitude D630 and everything was great. After a few months the laptop would every so often get a message saying:
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
It was ok after I fiddled with it and it would charge normally. Now the battery refuses to charge with my adapter and runs only on AC power. I assumed I just needed a new battery but then something weird happened. I used my girlfriends charger to charge my battery and it worked 2 times, but strangely after the last time her computer started getting the exact same message and hers was fine beforehand. Is the battery somehow draining the adapters? I've never heard of that happening before. What should I do?

This problem actually popped up on me a few months ago, but I was able to remove and insert the power cord a few times and the message would go away and I would be able to charge my battery. But as a month or two passed, it became more finicky, and I had to jiggle with it a little more, but still, I was able to charge my battery and use my laptop wire-free.
Now today, I've been trying all day, and cannot for the life of me get the battery to charge. I get the following message when I plug the wire in.
"The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 65W AC adapter or higher for best system operation."
Also, I think its worth nothing that a lot of people mention that this error message comes up while they are booting their Laptops, mine only comes up once Vista is loaded and I attempt to reinsert the cord.
So, I have tried another Dell charger, a 90W one, and the same problem does occur (My original is a 65W). I am planning on getting a different battery tomorrow to see if it is the battery, as this ones usable life was getting quite low, down to barely a half hour per full charge. My warranty, although I'm not sure of the specifics, was not expired when this problem first came up, but is now expired by I would say 2 months at the most.
Oh, I have a M1330, and I have gotten a lot of use out of this laptop

For the last two weeks, every time I start my Dell INSPIRON E1705 while using the power supply I am greeted with the following message. "The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation". I press the F1 Key and everything works fine. I've read about this on other websites and most say it's a design flaw in the power supply after the cord has been properly wound around the supply as designed. Apparently a few of the cords internal wire strands become broken and cause this message.

When I boot up my laptop, I get this exact error:
Quote:
The AC power 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 best system performance.
To resolve this issue, try to reseat the power adapter
Strike the F3 key (before the F1 or F2 key) if you do not want to see power warning messages again.
Strike the F1 key to continue, F2 to run the setup utility. Press F5 to un onboard diagnostics.

I recently updated from BIOS A08 to A09 if that matters. Any ideas?

Brand new Inspiron 13 7000 (7347) 2 in 1. Its just out of the box, and I'm just finishing windows updates and Dell Drivers.I seem to be getting this error message when I boot up, maybe 10-15 % of the time"AC power adapter wattage and type cannot be determined"..As with others, Press F1 to continue, F2 to check Bios, F3 to ignore this.In bios I see <unknown power adpater> I unplug and replug the power supply and it magically comes back as <65 watts>
When this issue is occuring, the battery won't charge, it held at 91%. I also got the warning in Windows one time.Is this just the power supply, or the laptop itself ?

I have a Inspiron n5110 laptop and for about a month it had a problem. It works fine (battery charges as usual) until a power drop (even for a second) occurs. When power comes back battery does not start to charge. It gives a error message "AC power adapter type cannot be determined"...
I suspected the fault may be with the power charger/adapter and searched for new one in the store. But there I came to know compatible adapter for my 15R laptop is a 90W adapter. [URL] ....
And I got a 130W adapter when buying this laptop. So I thought they must have switched it by accident and it didn't bother me since it worked fine until now. But according to store, the adapter I'm using now does NOT supposed to be compatible with N5110
This is what I have now : [URL] ....
I have a working 90W dell adapter from my friend and i tried it to my laptop. It also gives the same error as above except my laptop identifies it as a 90w adapter and asks for a 130W adapter instead(When my adapter is plugged-in it doesn't even identify it as 130W as you can see from the image).

So my power cord or battery is garfunkled and it doesn't hold a charge. I use my laptop (Dell Inspiron 1501) with the cable plugged in all the time. I'm perfectly happy with this and there is absolutely no way I'm paying any more for any charging equipment (battery or otherwise) when I can get a faster laptop for cheaper than the cost of the charging equipment. So I'm not going to spend any more money and I'm perfectly happy with how the laptop works.
I don't need a solution but when the laptop boots it stops at this error message (in the BIOS or DOS or w/e before the OS loads) until it gets some user input okaying it to continue booting.
I want to disable the message to allow the computer to boot into the OS when it is turned on. I either want the message to time out or not to appear at all. I looked in the BIOS (which is the simplest BIOS I've ever seen and has practically no options outside of boot protocol) and didn't see any options related to error messages or to act in any way.

I have encountered a problem with my laptop - a Dell XPS 15. When the computer turns on, or I insert the charger, the following error message appears:"The AC power adapter type cannot be determined. Your system will operate slower and battery will not charge. This problem might be solved by: Ensure the plug is inserted completely for best system operation. Connect a Dell 130W AC Adapter or higher." I first encountered this problem a few months ago but on occasion, I have managed to get it working by taking the charger in and out a few times.
Though over the last couple of days, it won't charge at all. I have tried using another charger, which yielded the same results; though it was not the exact same charger and actually has a lesser power output. I also checked the bios during start-up, and next to AC Adapter Type was 'Unknown'. Though the charger can power on the laptop without the battery inserted. Just yesterday, my computer also started operating a lot slower, at an almost unusable speed and I think this might be related.

I'm using a old dell inspiron 6400 this isn't my main laptop anymore but i still love it so i want to fix it a year or 2 ago the laptop wouldn't boot i fixed it by taking one ram stick out of DIMM B i have 2 slots it use to have 512mb on each side one on dimm A and one on Dimm B. I want to use the second ram stick so i can use 1024 mb of ram. if i put them both in numlock 9 is on(and shining green) numclock A and Numlock down arrow are blinking(green).
and also i get a arrow at boot saying the ac adapter type cannot be determined please connect a dell 65w charager or better for optimal preformance and blah blah the battery will not charge and performance will decrease. I purchased to dell chargers with my laptop a 65w and a 90w they both give the sam error i did research on both my problems until i joined this and someone said that the cords were flexed and the wires weren't connecting. well both of my chargers have been flexed for 1-2 years is this why?

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.

Whenever I connect AC adapter, display on my laptop goes black and it remians black even after I remove adapter. If I poweroff laptop while adapter connected and power on it again, the lights on keyborad just blinks and it shuts down. If I remove adapter and turn it on then it works fine.If I connect adapter while laptop is powered off then it charges the battery as usual .

My D620 suddenly stopped working with an AC adaptor, won't charge the battery, won't operate without the battery. I have several AC adaptors and none of them work now. However, when docked the ac works fine and the battery charges with no issue.

Has anybody tried to put a Latitude d620 ATG lcd display cover on regular D620? This seems like a simple switch but I would like to hear your opinions.

I've got a XPS 15 (L511Z) which recently stopped charging the battery. It says plugged in but not charging when I hover the mouse over the battery icon. Luckily I've got an extended warranty and on contacting Dell they sent out a new charger. I plugged that in and the same result. In fact now when I boot the laptop it gives me an "The AC adapter plugged in cannot be determined" message.
Dell then asked me to buy a new battery since batteries are not covered in the warranty. Did that but still no luck. Am thinking that the original battery was ok to begin with anyway! Dell then asked me to update the BIOS but when I tried to with the update they gave me it failed, saying incompatible with the current hardware.
I then ran the DELL Support Center utility which identified another BIOS update which updated successfully but then I noticed that it changed the Product to L501X now. The charging issue still persists though.I've sent a response back to Dell but based on what I've been reading on the forums it looks like the motherboard would have to be replaced.

trying to control the fan speed. I've tried i8kfangui31 but still no luck. Then I run the diagnostic software from Dell Support website, the result of the processor on/off test is error code 3700:011B -> my fan failed to slow down to 2500rpm. the fan keeps running at high speed (about 4500rpm). my bios is A10.

i recently bought a dell from craigslist a month or so ago and seemed to work fine, i recently installed ubuntu on it, i dont know if it has anything to do with my problem but anyways...
problem started when the laptop would shut off unexpectedly, but would start right back up fine.. i think it was due to overheating im not sure if the fan is working or not bcuz i hear no sounds coming from it. it showed a screen saying it shut down bcuz of it was getting too hot twice. i opened it up and checked for dust in the fan and cleaned it up. after it shut down about 3 or 4 times while using it, it wouldnt reboot. when i push the power button the three caps lock, number lock, and scroll lock will flash as does the power light then it will shut back down. occasionally it will boot and make it as far as the desktop screen then the screen will go black, but the lights will still be on as if the computer is still running, and i will have to hold the power button down to get it to turn off.
one thing i have noticed is that with the hard drive in the laptop it will make a beep noise then shutdown, if the hard drive is out it will shut down with no noise.
i have tried everything, i have reseated the ddr memory and tried running off just the power cable or just the battery with no success.

I have owned a Dell Latitude D620 for the last few years. Lately, i have realized that my 9-cell battery is only charging to 84% (4 weeks old), and it only gets about 1.50 hours on full charge.
Also, at random intervals, the LCD screen flickers and becomes blurry. All settings are default and there have been no modifications, here is my computer information.
Dell Latitude D620
Intel Core 2 Duo T7200 2.0GHz
2GB RAM
256MB Video Memory (nVIDIA Quadro 110)
Microsoft Windows XP Professional Service Pack 3 .....

Do you know of any ?
Does the "PR01X D/Port Replicator" have the IEEE 1394?
I have a lot of videos on my camcorder that I would like to burn on dvds and do not think the usb is going to work.

First want to say hi since this is my first post here, been a Thinkpad user for years(a regular member on thinkpad forums) but it died last week so I picked up a very nice D620 last night. So from now on you'll be seeing a lot of me here
I got a great deal on a D620 w/2Ghz Intel Core Duo & 2gb of DDR2 ram,
it's coming with XP Pro but I've been running Windows 7 here on my Dell Desktop since around February(RC/beta version then bought Ultimate version when it was released) and I have to say I like it a lot and would love to install it on the D620 when it comes,
has anyone here installed Windows 7 on their D620 and if so and have any driver problems or issues of any kind??
Thanks in advance and sure nice to be here...

I have a Dell Latitude D620 and I replaced the battery about a year ago. Now the Power Meter reads that the battery is connected and is charging but if I unplug the power,
the laptop immediately shuts off. It seems like the connection may not be good, but I have checked it several times and it looks fine.

A user of mine reported a problem with her screen being black. You can actually see the windows logon prompt but its really dark.
I set her up on a port replicator with an external monitor, which displays fine. So is it the display on the laptop monitor thats causing the problem? Its a Dell Latitude D620 noteboob

I bought a D620 a while back and added complete care since I travel a lot.
About a month ago the computer was involved in an accident and was completely destroyed.
Today I got the word that my D620 most probably would be replaced by the E5400.

My laptop (Latitude D620) is driving me..How do I turn off the touchpad and disable the top row (between touchpad and spacebar) of mouse buttons? When ever I'm in Word, or composing an email, the cursor moves up into previously typed text and starts typing from there instead of where I was at. I suspect it is the touchpad or the 'mouse' buttons between the touchpad and the space bar. On a ThinkPad there was way to turn off the touchpad, but still leave the joystick/pointer enabled. But I need to also disable the top row of mouse buttons.
In other words what I want is a set up where the joystick/pointer works and the bottom row (below the touchpad) of mouse buttons works, but not the touch pad itself, or the top row of buttons.It sounds funny, but it has become a severe productivity issue. The cursor jumping has happened 7 times just in this one email !!

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.
