M40 - AC plugged in but no 'Tension' or 'Charge' light up

Are my laptop works very well yesterday. This morning, I plugged the AC power, but it seems that it is not at all connected. I changed the wires... changed the socket... Also the fuse on the power cable but nothing.

Please help me and tell me if it is like a button lock of power or anything of the sort... because I think that the problem is minor and stupid, but I don't know... Thank you.

Hi Mohammed,.

It seems that if the problem may be with your power adapter. Check that you have actually found a DC voltage at the plug that connects to your laptop using a multimeter. Also check your adapter cable carefully in case there are breaks in the inner core.

Kind regards

    Hello

    It could be a number of reasons of a battery discharged to a problem with the charging circuit.

    1. go to Start / all programs / Accessories. Click on the command prompt and select run as administrator.

    2 in the command prompt window, copy / paste the following command.

    powercfg-energy-output %userprofile%\desktop\energy-report.html

    Press ENTER.

    Wait for the command to complete (usually about 2 minutes).

    This create a file named energy - report.html and place it on your desktop.

    3 go to your desktop and double-click the file to open.

    Scroll to the bottom for the battery: battery information section.

    You will see:

  • E8C34UA #ABA - Split X 2: Split HP X 2 - 2 plugged but battery does not charge

    Hello, I have a HP divided X 2 model number E8C34UA #ABA. I keep having a problem that says battery plugged 2 but not supported or 2 Bttery undetected. I see that other users of Split X 2 have the same Botr question, this issue has not been resolved. Any help would be appreciated.

    I was contacted by a case manager HP on the problems I've had. Even if my product is out of warranty, HP gave me a discount on the repair. They have replaced the battery inside the docking station and fixed another issue. I must say that I am very happy with HP and their representatives and will remain a loyal customer.

  • Satellite L450D - 11 X, battery plugged in but not supported.

    My Satellite L450D - 11 X (fairly new) is plugged in, but the battery won't charge and the battery light is orange. Life flows or increases when using it plugged. I tried updating the BIOS but don't know if I did this correctly. Thanks for any help in advance.

    You can try the following:

    1 reinsert the battery
    2 unplug the computer from the power adapter and turn it on. Let the computer battery power until the computer turns off, indicating that the battery is fully discharged.

    If it still doesn't load, it can be the malfunction of the accumulator. In this case, you must contact the Asp (SAV) to replace. They will do it for free as you say it's always new.

  • Plugged in, but does not load?

    My g6-2116nr Pavilion is only 3 months ago, but it will not load. While it is plugged in, it says that it is plugged in, but do not load. the only way so he could start charging is to let the battery run out and load it then (I don't let not run out on purpose). Occasionally, while it is fully charged, it also won't tell when the battery is down, and it will be a strange ammount of supposed autonomy (it will say that it has 130 hours of battery life, which it doesn't). Can someone help me?

    Hello

    First, shut down the laptop, unplug the power adapter, remove the battery and then hold the Power button for 30 seconds.

    Now, plug in the AC adapter without the battery inserted, start Notepad, open windows control panel, open Device Manager, expand the entry for the battery, on the right, click on and compatible Microsoft ACPI control method battery and select Uninstall - do uninstall not something else here.  When the uninstall is complete, shut down the laptop, unplug the AC adapter, reinsert the battery and then start the laptop's battery.  Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shut down the laptop again.  Now plug the power adapter (with the inserted battery always) and start the laptop to see if it helped the issue at all.

  • CLIQ locks whenever I plug in USB, but not the wall charger?

    A few days ago only my CLIQ started crashing everytime I have connect my original OEM USB data cable. I hear the phone read the sound to be plugged in, but it seems to cut before the full "ding", the phone freezes for a few seconds and then restarts. After the reboot, it loads and allows me to use it as a USB key as usual. Also, when I turn off the USB drive feature, it's the same crash/restart. None of this happens when you plug in the same cable, using the wall charger.

    Help please?

  • Pavilion dv4: battery does not charge even when it is plugged (load plugged says), but doesn't move 19%

    Hello hp Support Forums.

    Hardware specifications of the machine (if required):

    Laptop model: HP Pavilion dv4 Notebook PC
    OS: Windows 7 Home Premium x 64
    CPU: Intel (r) Core i5 - 3210M @ 2.50 GHz (4 processors)
    RAM: 8192 MB RAM (4096 MB x 2) DDR3
    Graphics card: Intel HD Graphics 4000 @ 1 696 MB
    Audio: IDT High Definition Audio 16-bit
    HARD drive: 750 GB SAMSUNG Spinpoint M8 ST750LM022 HN-M750MBB

    I own a laptop PC hp Pavilion dv4 laptop and this morning there was a sudden battery problem, I was playing Dota 2 and the Steam interface told me that the battery percentage was 12% (7 minutes from the end) then I moved and grabbed the chager, plugged into the outlet and plugged the charger in laptop a few seconds later the laptop turns off suddenly and won't restart, even if the charger is plugged there no light came from the load indicator.

    A few minutes later do research for similar problems, there was a solution to remove the battery and the charger then press and hold power for 30 seconds and 3-5 minutes then return the battery but it did nothing.

    After with some research, the indicator load on all of a sudden and when I start the laptop it was on 12 percent and billed not (there is no indicator that the charger is plugged) and turns off suddenly without warning.

    Later, with a bit of panic and thought, I removed the battery and the charge light lit, which allows me to boot up the laptop and when Windows starts, I plugged it to the battery and it says: 19% (plugged in, load) so I track for a bit, but it didn't move at all, even when I changed the power of High Performance for HP recommended settings , window 19% available (plugged in, load) but it's just, it, don't move or anything like that.

    EDIT: When I unplugged the charger to move my computer laptop and plugged in again, the indicator not lit and does not charge the battery thus forcing me to shut down or Hibernate, and remove the battery to the charge light.

    Your battery is quite likely to be having no longer life left.

    It is that if your laptop starts up without the battery, since the race, the battery test is not a viable option.

  • Printer not responding not connections (wireless printer) is good and solid. I replaced my old router wirelessly with a router of valuation. I had to plug it, but the printer does not respond now.

    Printer not responding not connections (wireless printer) is good and solid. I replaced my old router wirelessly with a router of valuation.  I had to plug it, but the printer does not respond now.

    Is what brand and model of printer?

    I do not work unless your new router has the same SSID and password wireless as the old. Consult your printer documentation to find out how to handle the situation. For example, some Lexmark wireless printers have a program called Configuration Utility Wireless in the Lexmark folder under all programs on the start menu that is used to set up the printer when changes are made to the wireless network.
