    Had the same prob with AC adaptor not being recognized.
    In Device manager uninstall microsoft AC Adaptor - unplug AC jack and then plug back.
    Worked for me :-)

    I have a Dell 1735 with all of the Dells and Whistles, spare no expense. This was supposed to be the best computer that I ever bought and expected that it would last at least 5 years. But its only been two years and things are going to shi!. Guess its just a coincidence that the warranty is up...or not. Now this thing won't take a charge and I have no mobility. I'm very discouraged seeing all of the messages before mine. I can't believe that a big company like Dell won't fix an obvious defect. They should recall all of these systems if they cared about their customers at all. I will be calling Dell for perhaps no other reason to tell the most senior manager that will talk to me, that this is my third Dell and most likely about to be my last one. If I have to, I will pay the $400 or whatever it's going to cost to get this thing fixed. And it will be for no other reason than to sell it and buy a quality computer. I guess this explains why Dell has gone from #1 to #3. Who'd have thought Acer sells more computers that Dell now.

  • I keep telling everyone. Make sure you have the correct power adapter. eBay has some "great" deals on the PA-10 family of chargers. However, my dinosaur Latitude D610 needs the PA-12 to be recognized & charge the system.

  • For 2 years, I've been using the Dell power adapter that came with the computer. Its a 19.5 volt adapter and its worked well up until the night before last. I tried my wife's adapter which is also 19.5 volts. It also does not work.

  • Hossam - Why don't you just POST your information. I doubt anyone is going to call across the world and try to communicate with a stranger who could be pushing a phone number that would charge tons of fee's to anyone that tries calling it...

    IF you have tried replacing the battery - you have replaced the AD adapter - and you have replaced the DC power jack - THEN YOUR PROBLEM LIES ON THE MOTHERBOARD CIRCUITRY and you will have to get an Oscilloscope - the board schematic - a hair dryer to remove the damaged chip - and of course - you will need replacement chips. There are probably 1 - 5 chips that have become faulty (each chip costs about .001 cents in us dollars and you buy them in Reels of 10,000 and more - have fun buying ONE...). Florida motherboard specialists do this for about 100 bucks on ebay - Precision motherboard in Miami also does this for about the same fee. There are some obsure websites that will sell you motherboard schematics for a fee of about $10 to $20. USdollars. By the time you add it up its going to be cheaper to send it out to a mobo repair place for 100 bucks; unless you are lucky enough to find a Repair tech who has all this - and charges you less... (not likely since any oscilloscope costs $1500 to $30,000 ...)

  • DEAR FRIENDS,
    THE PROBLEM IS NOT WITH BATTERY OR POWER ADAPTER
    The problem is with the tiny centre pin of the power plug.
    The centre pin is only used for data communication between your adapter & laptop

  • I disagree - the TINY CENTER PIN of the dc power jack does nothing. - There MAY three terminal connections on the end connector - but there are only TWO WIRES GOING DOWN THE CORD - I am sure of this on all dell C series - D series - and the newer line comparable to the 1520's - I suppose that there would be a few models that DO have more than two wires going down the ac cable; however if you follow my trouble shooting guide your problem will be solved.
    1: Check battery
    2: Check AD adapter
    3: Check DC power jack to motherboard connector/wire/ whatever it is

    if it is not one of those three things then you have faulty circuitry on the motherboard that can be repaired by someone with experience - not by the folks at Best Buy - not likely at any local computer repair shop either... you need a tech that has advanced skills (and tools) - You could get it done for as low as $50 bucks if you look for a bargain - and for no more than $100 if you go with one of the ebay advertisers.

      Further to my comment 05/07/2013 (H0w did that happen - see present date!), I have tried all the suggestions so far to date - 21/07/2013! bar soldering hardware. Nothing has worked. My wife's Dell Inspiron 1750 laptop will only work when connected to the mains. Never another Dell.

  • Thanks for the info...it's very timely since I just bought a brand new battery and it did absolutely nothing to solve this problem. What I've noticed is that once I plug in the adapter (by the way, I bought another one of those too and it did not help)the charging light goes on for about one second, it turns red and then goes out. It really does seem like its a circuitry issue that was caused by something Dell did or didn't do when they built this piece of crap. Oh well, I guess I needed something tlike this o motivate me more to buy an Apple.

  • Anything can break - Buy the extended warranty and GET RID OF it before the warranty expires -

    Bah - Puke - Apple - People need to remember that companies don't set out to make a faulty product - sometimes its just an 'oops' on the engineering - sometimes its a cut corner on a supply part from a manufacturer who is cheaper - sometimes you just have bad luck. With ANY electronic product- purchase the extended warranty - nobody knows if it will last - not even the designers... it takes years to know how one laptop stacks up against another - and this type of problem could be caused by a power spike from your home that is no fault of the people who made the laptop. Yes sometimes companies (MOST of them) screw up on a design - and no they will never admit it - yes they will deny it - cover it up - and hope it goes away - APPLE is not going to make your life any easier - there has been documented proof that the Apple engineers subscribe to a policy of "Planned obsolescence" where they design and engineer their products to last through the warranty period - but also FAIL shortly after said warranty so that consumers will buy a replacement. - I'm sure most companies subscribe to that crappy system to boost sales and repairs.

  • I’m frustrated
    I have recently had this same problem. I have had my computer (Dell Inspiron 1501) for two years and it was a year old when I got it. It runs great, has no speed issues, and updates well....but a year ago my power supply went out. I got a new one. This fixed the problem until a couple of months ago. I noticed that my battery would charge sometimes then wouldn't others. This happen for three or four days before it finally stopped charging altogether. I decided to try a new battery. I just received my new one yesterday and it still won't charge. My computer recognizes that it is plugged in, but it just won't charge the battery. I have noticed that the place in the back where it plugs in seems to be lose. I am wondering if this could cause the problem. I just don't understand why it can recognize that the supply is there enough to not utilize my battery, yet not enough to charge the battery.

  • The problem affects many laptops with certain dell laptop power plug sockets, These sockets are soldered onto the mother board and can be replaced. The fault that i have found is that the plug gets hit or bumped hard and causes damage to the power cord female plug that is mounted to the motherboard.Solder joints that are on ths plug can become easily damged and often just reheating the solder can fix the problem. For dell to solder a power supply socket to a motherboard is a very bad Idea, the best method is for the power plug to be mounted seperately with wires ataching itself to the motherboard, This eliminates the problem.

  • In my friends laptop the same problem exist, it is found that the centre lead of the power connector to laptop is break in the adapter cable.
    The solution is simple.
    I just open the power adapter ,then removed the chip connected to the centre wire and solder the same chip inside the laptop itself. The old centre wire is disconnected. Now the laptop is recognizing the adapter, charging fine.

  • I’m indifferent
    The puppy chewed through the charger cord and my husband started getting the "this is not a dell charger" message and the battery would no longer charge. Ordered after market power cord and same problem. However, after reading through this forum I saw the post about reseating the battery a few times and it started recognizing it. Hubby tried is and sure enough, the computer is now reading the battery is charged, not giving the message about the power cord and is charging the battery while plugged in.

    Seems like this is a problem with Dells all across their product line. This is our LAST Dell for sure, but at least it is working for now. We started dealing with them about a hard drive problem way before the warranty expired. Well, they drug their feet and drug their feet to the point that it is now out from under warranty. With the charging problem solved, we'll buy a new hard drive and install it. As soon as financially possible, the Dell is going to the junk heap!!!

  • The problem is caused by Dell's own greed. The little pin in the middle of the charger tells the laptop that it's a genuine charger, the serial number of the charger, the power rating, the model number, etc. If the laptop's BIOS recognises it as being underpowered (eg, a 3.34A charger when it wants 4.46A), or if it doesn't get any of this information from the charger, it refuses to charge the battery (which also has a similar "genuine Dell product" detection system).
    After a while, it would seem that the circuit which monitors the charger and battery data dies, so even with a brand new genuine Dell battery and charger, it won't charge, giving you the "Power adaptor cannot be recognised" type error.
    I am trying to find a way of hacking the BIOS to ignore the battery and charger type.

    I've found a similar hack for IBM and HP laptops to ignore the wireless network card model/type. (Apparently they claim it's in order to comply with FCC rules, but personally, I think it's just to make you buy parts from them!)

    I have two Dell laptops which are saying "battery cannot be recognised", losing me money sat on the shelf even though they are otherwise fully refurbished and ready to sell.

    As a laptop repair specialist, the three brands I rank as least reliable (or most troublesome), are: 1) Sony, 2) Dell, 3) HP
    ...and most reliable: 1) Toshiba, 2) Acer, 3) Samsung
    (This is purely my own opinion, based on about 4 years of repairing and refurbishing laptops)

  • Well here's a thing... same problem. Nothing worked - tried all the suggestions out there, but to no avail... then... I had to splice a new jack onto the charger lead (original broke) which initially made no difference, but my soldering was crap which meant that I had to re-solder the joints. At which point I ran out of wire length up to the 'choke' - that block at the end of the power cable before the jack - and had to ditch it. having cut the choke out of the cable and re-soldered the joint, my laptop is now re-charging! RESULT!!

    The choke appears to be there to reduce interference, so it's not a power control issue and it's absence is not likely to be problem... So if you've got a good pair of wire cutters and can solder a joint, what's to loose!

  • I have a dell E4300 with the same problem and tried all. (bios upgrade, etc, etc.) what did work was to go into the device manager and remove all the battery related drivers that it would let me and then have it check for hardware changes. when the drivers re-installed it started charging again. Don't know if it will work in all cases, but it just worked for me.

    My Dell Latitude D430 problem isn't about the charger, it is a dell charger It's not that old so I'm assuming the one it came with it (gift from an inlaw) but my battery says it's not installed even when it's in. It runs off the charger cord just fine but wont charge or recognize that theres a battery at all. Would a new battery fix this or is it a hardware problem?

  • Rena, we have found no solution to this problem. It seems to only be found in Dells. No other computer brand we've ever owned has had issues with charging or not recognizing a power supply that has the proper voltage. I really like Ed's solution! We have since bought him a Toshiba and it's doing great!

  • My Dell Inspiron started having this problem as well. I spilled something on the keyboard and set the computer on its side quickly to make sure the liquid dripped off before it screwed up the keyboard. That's when the problem started. I then read this post and the post earlier about a piece inside soldered to the motherboard is probably right. I solved mine simply by turning the laptop on the opposite side and jiggling the power adapter a little. Now it works and indicates its charging (before it either said "discharging" or "idle"). Gravity probably pulled whatever piece is inside the other direction, bringing it back into place. A new battery or charger will not help this problem! It's just bad construction by the engineers. If you can't solve your problem easily, you will need to find someone who's comfortable taking apart laptops, so he or she can make the hardware inside is secure to the motherboard. I took my laptop partially apart once because the video cable had come loose (I fixed that problem, too) but taking apart a laptop is a tricky business for those who aren't comfortable doing such things. But when your laptop is out of warranty, what choice do you have! Many problems are simpler to fix than you think.

  • hi
    on dell latitude d620 i have problem with dc power.
    if i move dc connector, latop turn off (i do not have any battery because charger does not work) or monitor and fan off while hard disk stil on.
    sometime overheting error appear when i reboot.

    what i did:
    1. tried another power adapter - same problem
    2. cleaned from dust - same problem
    3. resoldered DC power jack on motherboard- same problem
    4. replaced the DC power jack - same problem even worst

    I do not know what to do next.
    Any suggestions - idea?

    thanks, michele
    • Carefully break the charger open. Cut the output cable about 3 inches from the block, strip it back and resolder into place on the charger PCB.
      This is a skilled job and requires good soldering skill, heat shrink and gluing the charger back together with epoxy afterwards.
      The thin white wire in the center of the wire (3 cores) gets broken by people wrapping it too tightly around the "brick". After doing this, your charger will almost certainly work! (Sometimes, but rarely, it's due to a faulty "receiver" chip on the motherboard)
      Again, this is not a job for an amateur, and the charger should be given at least an hour after use to discharge the high voltage capacitors!

    I was told by dell service centre at Bangalore that Charger is fine and Battery is fine
    Its due to motherboard issue that battery is not charging...ask to change mother boad which is very expensive for this simple issue i think so..Junk Laptop will throw it in dustbin

  • CHARGER NOT RECOGNIZED:
    1) Try removing "Microsoft AC Adaptor" or similar from Device Manager, unplug charging connector, plug back in. (If your battery is dead, remove it then restart)
    2) Check if the DC socket on your laptop appears slightly loose. If it has had any excessive force applied, it may have broken the solder connection to the motherboard. A repair shop (like me) will charge about £40 / $50 to repair it, as it involved stripping the laptop and taking out the motherboard.
    3) Buy a NEW GENUINE charger from ebay of the right charger family. There are several types of Dell charger and if you don't use the right one, it won't recognise it, so some research may be necessary. A genuine charger should only cost about £15 / $20, and will always have the Dell logo on it.
    Alternatively, if the output wire next to the "brick" has an obvious kink or bulge, you could try repairing it:

    CHARGER REPAIR:
    Carefully break the charger open (a chisel or flat screwdriver on the join, hit with your hand is normally enough to crack the seal open). Cut the output cable about 3 inches from the block, strip it back and resolder into place on the charger PCB.
    This is a skilled job and requires good soldering skill, heat shrink and gluing the charger back together with epoxy afterwards.
    The thin white wire in the center of the wire (3 cores) gets broken by people wrapping it too tightly around the "brick". After doing this, your charger will almost certainly work! (Sometimes, but rarely, it's due to a faulty "receiver" chip on the motherboard)

  • Thanks to the forum members for giving their valuable replies, I learned several new things from this discussion.coming to the problem I have some check list, that is this problem is of two types
    1) hardware
    2) software
    let us now
    first check with the hardware problem
    1) Power is there and all the power connections are properly earthed or grounded ( earthing prevents damage of tiny electronic devices of the computer)
    2)check that power plug is it is fine and working (use tester to check)
    3)check that the led (green or red) on the adopter is glowing
    4) if it is not glowing (check for any power failure from mains), move the adopter wire bit smoothly ( to find any loose contacts)
    5) if the light is glowing when the wire is vibrated or moved (it is due to loose contacts at the interface ( see this video: it is dangerous to work with AC be careful, and it is up to you to try as it is in the video https://www.youtube.com/watch?v=CAkfr2... ) hope your problem will be solved with this video, if it is the problem with out side hardware
    but be careful while opening the adopter,first take out or remove the adopter from the power plug from holders (main supply). then you do (ac power is too dangerous)
    If it is the problem with the internal hardware it is better to avail customer care services of dell tech support services
    secondly.
    if every thing is fine,
    main power is there
    earthing is there
    light is glowing on the power adapter
    and your lap top is unable to recognize that adopter is connected to ac mains means there is software problem try to follow the reply given by phil.
    for that first right click on the my computer icon on your desktop,
    select the computer management option
    leads to device manager here you can check for device manager select that
    on to the right of that when you select it you can see batteries section click it , now you can see 3 options microsoft ac adapter, microsoft acpi...etc..
    right click on microsoft ac adapter and uninstall and follow the instruction of phill
    hope now you could do it.

    still you need some support. Then it is always better to avail or consult the customer care services of dell tech support than fingering it on our own..
    If you want to have the details of customer care contact numbers of Dell tech support you can get it from the website link http://customercaresupportnumber.com/... directly
    other wise you can browse for different options from
    http://customercaresupportnumber.com/
    I hope this will help most of them facing AC adopter problem, discussed here.

  • I had the same issue occur a few times randomly. I figured turning the pin while its pushed all the way into the power jack solves the issue. Its definitely some rogue signal that causes that annoying message to pop up.

    As a precaution, do not stress or bend the cord too tightly near the choke (the cylindrical thing near the power pin) to avoid this issue.
    • It depends on your power settings in the bios. On the older Precisions I've had them setup to use full power and they refused to even recognize a 65W adapter was plugged in until you turn on all kinds of power saving and throttling options.

      However once you shut them down they will charge just fine off a 65W adapter.

      There's more to this than 65W vs. 90W. If that had been the only difference, you would not be having a problem. In selecting a charger unit, you need to make sure several items match up:
      1. Is the charger unit supplying AC or DC to the laptop? MUST be same as specified for the original charger.
      2. Type of battery in the laptop. Many chargers are designed for a particular battery type and supply exactly the right voltage and charging rate (current) for that. Some even are "programmed" to alter the charging rate depending on the state of the battery's charge. All have a limit on the battery's maximum voltage to avoid over-charging. All of these are important, and that's why using the wrong charger can cause trouble.
      3. Polarity of the connector - MUST be the same as original.
      4. Voltage MUST be the same.

  • I’m very very angry
    I am really annoyed that I bought a high end Alienware that can not even charge it's battery with the ac adapter it came with. This is an ongoing problem and there needs to be a fix. Why isn't there a driver we can install that over rides the microsoft driver. I am constantly uninstalling my microsoft ac driver to get my power cord to charge my battery. It is so annoying. I have to go through these motions constantly as it stops working everytime I turn of the computer. You don't have an emoticon for how I feel.. which is Muderous.

  • I’m hoping new modem=un-needed!
    My discovery: Dell (new-hardly ever use except weekends,odd days), Inpirion-laptap "adapter-plug into computer" (at back-left-side), "wobbles in and out" all-by itself! I also found "numerous" co-Dell-users, online, who have "also" figured-out the problem: The "plug-in" does Not remain "secure" in the hole (this plus-in is "round" with Zero "line-up" needed; it did fit snuggly when first purchased in Apr. 2013. Please note: persons are having this problem "right out of the box." PHoned AT&T "Tech-support" to "let them in-on" what many of their customer-issues with "dropped-Services" 'may' be with Dell-laptaps: After "implying" WIFI signal-dropping and/or "dropped-signal (Ethernet/WIFI/Service 1,2, or all 3) from AT&T; "and" ordering a new-modem (Dell laptop (new) Inspirion) would also not "even" screen-"on" (Geek Squad said zero wrong with WIFI: powered up @ Best Buy!); "and" ordering a "faster-service for $5 more per mo./from AT&T," I Finally" spent two early-am hours attempting to "figure out" "What the Heck Is Up With Dell Inspirion (new) laptop"! If you have "out-of-box/new/warranty still" check-out "this" Heads-Up issue,asap!
