Laptop not charging problem

I have dell laptop inspiron 1440 with woindows 7 ultimate. When I connect the charger for laptop, it says "Unknown adapter detected" but sometimes, it works fine, BUT then after the load up to 80% or more, he stops the charge and said "plugged in, not charging"... What could be the possible reason?

I have to buy a new charger? Please help its really annoynig.

Thanks in advance

Hi David,

Please go to the Microsoft Community Forums.
 
I want to tell you that it's a hardware problem. The card is faulty or the charger on the motherboard component does not work. In most cases, the problem is with the motherboard.
 
So, I suggest you to contact Dell for assistance.

  • IN BRANCH, NOT CHARGING problem

    Hello. my laptop does not load. It says PLUGGED IN, NO charging CURRENT. I thought it was the batterys foult but replace it with a new one, but still the same problem. Help, please

    ,

    Check with support from the manufacturer of their books online and the drivers and their forums system
    (as applicable) for known issues. Some manufacturer issued BIOS and other updates to help the battery
    problems.

    Control Panel control - plan change Options - power plans - power - advanced settings
    Parameters for the drainage and the use of parameters (this is how much to use and not how much or how)
    long to load).

    In fact, what causes a lot of wear on a battery empties it too low on several occasions. With today
    systems overload are not a problem.

    Here are some tips to help and troubleshoot battery issues.

    Old battery? Unplug the power to the computer - remove the battery and clean the contacts with a pencil
    eraser (do not use this, if your battery is fine slots - just clean up the edges of the knife which fit in)
    them and be careful). Batteries are old, or it could be a problem with the computer.
    Check with the support of the machine system, and many of them have on line forums.

    New Lithium-Ion type battery usually last longer if you do not unload then less than 30%
    However on a laptop that not extend their life a lot. Best is to use the a/c adapter
    When this is possible.

    I use the free version of BatteryBar to monitor my battery. Click on the green button on the
    Yellow box on the right side of the page to download the latest stable version.

  • HP-n240tx: laptop not charge up

    Hi guys...

    I have a hp laptop that is about a year and model n240tx... this problem has happened today when suddenly, my phone says connected but do not load on the battery and unfortunately when it happened to my battery said it was 9% and immediately turn off the power

    I did the thing to reset the power when I remove the battery and adapter and power button press and hold... I did it and my laptop did start up office and new such dangerously low battery 7% and closing down and now not even start flashing white led near port (mind you it was with the laptop connected to the power supply) load

    And it seems that my laptop doesn't start when the battery is removed because when I tried to do it just stops immediately with a little beep in the speakers

    PS: I also noticed that when the laptop started to 7%, he went back to the base... not even in the hd4400 or the gt740m display, also Ive rarely ever used my battery, he operated mainly on the sector (maybe this caused a dead battery?)

    Ive read abt this and many say this can be a defective Board on the laptop, but I think that this could be a dead battery problem? Since it is a question of holiday I can't remove for repair shop, so I would like some info of experts on this issue

    Hello;

    Let me welcome you on the HP forums!

    I read your post on your charger and battery problems and wanted to help.

    The diagnostic approach is to test both the dough and the charger, but in both cases, you must follow the instuctions that we could post a working laptop.  I'll post the links below:

    HP laptops - to help and the power adapter testing alternative | HP® customer support

    Computers laptops HP - HP battery check the frequently asked Questions for laptops (Windows 7 and Vista) | HP® customer support

    If you can't make it work enough to use these links, because we have no way of diagnosing the problem from here, your only recourse is to take the PC to a HP Service Center and ask them to look at.

    Here's a link with information about HP Service Centers: http://support.hp.com/us-en/document/c00372730?jumpid=reg_r1002_usen_c-001_title_r0004

    Good luck

  • Laptop not charging and not turning not not on also

    Hi, my laptop (dell Inspiron 15 7000 series-7537) is not load, tried the charger with another laptop and it works, certainly isn't evil, it also sometimes does when I load it charger 'as it indicates no current charging"on the screen... Any ideas on what to do or I have to send in repairs and how much it will cost me?

    The system light up at all?  If not, unplug, remove or disconnect the battery and hold the power for 30 seconds.  Remove the base and remove and reinstall the bars of memory.  Plug the AC adapter and see if it will turn on.  If it goes with the battery disconnected, but not with it connected, the battery is bad.

    If it still doesn't light up, check the USB ports for damaged pins that can cause a short circuit.  Otherwise, if you have already tried a new Dell adapter without result, the power supply is the next possible suspect - who is part of a $35:

    www.Parts-People.com/index.php

    If replacement that does not solve the problem, looking at a replacement motherboard - the order of several hundreds of dollars for the party as well as the labor to install.

    Dear Sir.

    My laptop a DV4-1199th does not rotate if the power light is on when the battery is out. When I installed a charged battery, it lights, but the power light is off and the battery won't charge (in fact that it discharges).  I have to recharge the battery when the phone is turned off. Laptop also only lights up the battery (disconnected from the power supply. What should be the problem?

Here is a link to calibrate and test the battery.  Here is a link to solve the problems of the battery on a laptop. You should be able to complete these with the laptop plugged into the AC adapter.

  • Pavilion 15 laptop: replacement charger problem

    My charger for this phone (740015-003) packed and I ordered the HP (741727-001) of replacement recommended a supplier online.

    I got HP 709985-001 and would like to know if this charger will be ok for my laptop?

    Difficult to contact HP directly ask the question, this Forum is my last resort?

    @Ralphie-2

    Works perfectly.

    It's OK to go higher on the amps.

    You do not have to go further down that which needs the laptop.

    Which will cause the adapter to overheat.

    One you have will work fine.

  • Pavilion 15-p035nd: laptop not charging

    Hello.

    I got my laptop from Komplett.ie last week, and he played well for the seven days later. However, while using it last night, it stopped loading all of a sudden.

    He has been connected to a pocket of work, since he had previously supported. I checked the cables for kinks and found nothing. I used a different power cable to plug the adapter into the wall outlet. I used another socket. I removed the battery and cable, discharged from the laptop and tried to turn it on so that connected without battery.

    None of this has worked. The powers single computer laptop on while battery is in, running only on battery power. The only thing I could not test is a second card.

    What can I do to fix this?

    If the duct is not powered when the adapter is connected, the adapter is likely to have failed. It is a part of replaceable warranty.

    Good evening.

    The problem with the battery of my XPS 17 L702X started a few months ago. My House has lost power 3 or 4 times in 2 minutes while my laptop was connected to the grid. Since then, my laptop not charging the battery. The message is: "plugged in, not charging. I bought a new battery, but the problem persists.

    Thanks for any help.

    Salvation ROAD, map

    You use the original Dell adapter for the model of this system? The adapter is frayed? The adapter stays in the company when it's plugged in or it falls easily?

    Reboot the system and press the f2 key to enter the BIOS - check the adapter status in the BIOS with and without the smart card. In addition, shake the plug of the adapter at the end and check if the status of the card changes at any time.

    Test with another adapter to power if possible.

    If the port is loose, then the DC port must be replaced otherwise, the adapter must be replaced.

    If there is no guarantee, then you can contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ

  • iPhone 5 c will not charge via USB on the laptop?

    Hi all.

    I have an iPhone 5 c and as about a week ago, does not charge via the USB port on my laptop. He sees very well in my wall sockets and Sockets USB as well, but not in my laptop. I have an Acer laptop running Windows 7. Windows is up to date, iTunes has the latest version installed. Whenever I plug in my phone, one of the following conditions occurs:

    (1) does not have

    (2) noise "plugged" USB lights, the window on the lower right, tell that a USB device has malfunctioned

    (3) (rarely) of phone calls after I tried several things

    What happened is I would plug my phone, she would charge via USB, iTunes opens automatically, and "trust to this computer" popup would come on my phone if I had unlocked it. None of this is happening now. I did the following to try to remedy:

    (1) power cord iPhone replaced (it was time for a new anyway)

    (2) uninstalled and reinstalled iTunes

    (3) restart computer and phone probably 29856 times

    (4) device Manager... nothing comes up at all, not even the unknown device. RARELY the unknown device comes up, then I get a "Code 10: this device cannot start" error, but it is * in a handbasket just trying to get to THIS point! and IF I do what they say to do to correct a code 10 (uninstall all USB and restart the computer, then USB devices hook to the top one at a time), so I'm now at my problem of a communication that don't meet pluse between my phone and PC

    5) tried to the registry editor, but not "upper filters" option rises

    (6) virtually every other option on this thread of 5 pages iphone not recognized by Windows 7

    Help, please?

    The USB port of your laptop does not provide sufficient power to recharge the phone. It is a hardware problem with your laptop, not the phone.

  • My laptop is plugged in but not charging

    My phone displays 'sometimes' that it does not load even if the power is connected.

    I called HP Tech Support twice.  Each time, they asked me to update the BIOS and firmware

    before performing the battery test (both at startup and using HP diagnostic S/W).  The test always

    said that the battery is OK.  I can run the laptop without battery installed without any problem, which

    probably does the charger.

    This problem comes and goes.  HP is unwilling to do anything until the problem can be clearly

    identified.  My warranty is about to expire (in 3 days), and I'm afraid that this problem won't get

    resolved before this date.  Could someone help me with this problem?

    Thank you.
