MagSafe adapter does not work after all the stuff that followed and merge card Ok?

My Megasafe duck-head adapter used with a Macbook pro has stopped working while my back was turned!

After trying all the controls and the actions described in the Apple support pages, it always dows not turn on or show any current to the small pins when checked with a multimeter.

It is the death of the adapter or can it receive some kind of CPR?

Chris.

Hello!

Could specify you which checks and actions you have done already?

Your MacBook came with both a cable to connect to the power supply and plug adapter. Could you try both to see if it works? You might just have a broken charger.

Please find instructions for that here: reset the management system (SCM) controller on your Mac - Apple Support

If the battery is good behaviour

  1. Stop the Mac.
  2. Plug the MagSafe or USB - C adapter to a power source and to your Mac.
  3. Use the built-in keyboard, press shift-control-Option on the left side of the keyboard, then press the power button at the same time.
  4. All the keys to unlock, then press the power button to turn on your Mac

If the battery is removable

  1. Stop the Mac.
  2. Unplug the MagSafe from Mac power adapter.
  3. Remove the battery. (Learn about removing the battery in the MacBook and MacBook Pro computers).
  4. Press and hold the power button for 5 seconds.
  5. Reconnect the battery and the MagSafe power adapter.
  6. Press the power button to turn on the Mac.

Thanks for posting the results!

  • HARD does not work after changing the disk partitions recovery media creator

    Hello world

    After installing windoows 8.1 April major upgrade (win 8.1 presents as OEM), and have shrunk C partition to create a data partition "D", "Troubleshooting" option under advanced start menu is no longer available.

    Toshiba Recovery Media Creator does not work, too (it can not find any hard disk recovery partion).
    I got in the OEM recovery partition.
    I am also able to create a recovery using the Windows tool unit.
    You have no idea about it?

    Thank you very much!

    Hello

    Sorry to hear about all this. Unfortunately, you now have a big problem. I don't understand why you didn't create support of recovery before you started to change the factory settings, including to change the structure of the partitions of HARD drive.

    Mobile offered with factory settings a structure specific partitions and recovery recorded image is saved on the partition of drive specific and marked with invisible markers. These markers are visible for preinstalled Toshiba recovery media creator tool and when you start the tool can find points of reference and has full access to specific files.

    Unfortunately, after changing the original scores structure Toshiba tool cannot find these markers more and is not able to copy files from recovery media recovery. What you need now is the original recovery disk. Using this disk, you can install original recovery image and after doing this, you will have new factory settings.

    I know it sounds stupid now but you must order the original recovery disk and it can be done on https://backupmedia.toshiba.eu/landing.aspx

    If you have any other questions you are welcome.

  • Firefox does not work after all, uninstall them and reinstall.

    Very few of the buttons are used in the firefox menu. Add ons will not open the Manager. None of the buttons on the open Help menu, open only a few menu options. Does not work in safe mode. I completely uninstalled, went into effect the deleted data from the preferences file. Reinstalled several times and nothing... Kind of frustrating. Any ideas?

    In case someone else runs into this I thought about it. I had to remove the program, remove the Preferences folder in Appdata, then click on registry local machine > software > mozilla and then delete the registry keys. There are three folders, I don't remember the exact name, but they all began with Mozilla. Once I did, I rebooted and reinstalled. Now it works...

  • Y700 - Dolby Audio does not work after resetting the system

    After resetting my computer to factory settings, audio dolby does not work. This is the error message I get:

    "Your installation is missing components. Reinstall the audio driver or the stand-alone components available on the support site for the manufacturer of your PC. »

    His works on my computer, just not this request.

    Thanks for the help.

    Matt

    I have the same problem, I have a 70-Z40 and the Dolby Digital Plus open, but does not work, you can choose the profile but is not even, I have this problem after the last windows 10 updated a few days ago.

    I hope you can help, thanks in advance

    EDIT: I solved it after a few tries, I don't know if it is the best way, but it's how I solve this problem:

    (1) Delete last windows update (after that, it did not)

    (2) delete the sound driver from Device Manager and reboot (it did not)

    (3) download the driver for my lenovo model page and install it (it did not)

    (4) any uninstall Conexant audio and Dolby of my computer and re - install again (it does not), it seems that my dolby 7.6.4.9 driver version is not correct, I need the 7.5.1.1

    (5) again to uninstall everything and restart

    -From there, he solved my problem

    (6) go on my computer (my system is in Spanish, so I don't know the correct name for the version in English, sorry) and then go to the Lenovo partition, then open drivers > Audio > Setup.exe This will install your Conexant audio driver, and then restart.

    (7) after you restart your laptor, do the same thing... Lenovo > drivers > Audio > DolbyGUI > x 64 > DolbyDigitalPlusHT.msi, and then restart your computer and it should work fine.

    Sorry for my English.

  • Update of Vista 32 bit does not work after replacing the hard drive

    A month ago the hard drive of my computer (ACER Aspire 6920) had to be replaced. The disk image hard precedent (which includes the c: with Windows Vista Home Premium 32 bit, SP 2 build 6002) has been mirrored to the new hard drive. Everything seemed to work fine until I noticed that I don't have more updates from Microsoft. I tried a manual update and got the message that the update service was not working and I have to restart the computer. However, the Task Manager showed that the update service has been executed. Of course, I rebooted the computer, but nothing has changed.

    I found a whole bunch of recommendations for this issue in this forum, but nothing seems to work:

    • The Microsoft FixIT tool indicates a problem with the update of components, and then said that the problem had been solved successfully. However, the problem is still there and rerun the FixIt tool Gets the same message on a problem (yet) found and fixed.
    • I also stopped the update service, delete all content in Windows/C:\Windows\SoftwareDistribution and restarted the service. without success.
    • I've temporarily disabled my security suite (Eset Smart Security 6) and tried the update. I also have fittings the folder C:\Windows\SoftwareDistribution to the scope of the antivirus, without success. On the old hard drive, I used a different security suite so I thought that maybe the ESET (that I installed everything recently) could be the cause of the problem, but that doesn't seem to be the case.
    • I also followed the instructions provided by Microsoft at http://support.microsoft.com/kb/971058, but again, no change at all. However, it should be noted that registering some DLLs that Microsoft listed does not work (message that the DLL is not found or some server entry point (my translation, I'm using the German UI and don't know English good term; sorry) could not be found.)

    Http://support.microsoft.com/kb/947821 , I found another tool that supposedly can solve some problems of updating; I downloaded the version for Vista 32-bit, but it cannot install it on my computer (error code = 0xc8000247 during installation).

    So I'm really lost now what else to do. I would appreciate any suggestions. Please note that I am not technically very warned :)

    ARG, apologies.

    Was not aware that they had dropped support for Vista... (I myself have 'graduated' Vista earlier)

    The fact that you have not already installed TSRI is exactly your problem.

    Recent hard drives using 'Sectors 4 K', also known as 'Advanced Format Technology'.

    If the installed hard disk driver currently is not compatible with this specification,

    It will result in oddities like the status of the service Windows Update is not recognized correctly.

    Installation TSRI will fix this in most cases.

    Alternatively, if you are using Vista SP1 or later version (or 7 SP1), you can use the real driver.

    Since you are already updated to SP2, we will see if it is a viable solution.

    Go to: start-> Control Panel-> programs-> programs and features

    In the list of installed programs, locate and remove if found.

    -Intel Matrix Storage Manager

    -Intel Turbo Memory

    This should force your computer to go back to the real driver provided by Vista.

  • Restart-VMHost does not work after unplug the vCenter

    Hello

    Hope someone can help me with this.

    The restart-VMHost does not work in my script. The output says vCenter connection error is required by the current operation. The connection does not exist, perhaps because it was actively closed or expired.

    What I try to achieve in the next script is all virtual machines stop and then restart the host. Since the vCenter is a virtual machine that needs to be stopped. If the script connects to each guests instead of vCenter

    SE connect-VIServer-get server #to "vcenter01", a list of hosts before stopping the vCenter
    $hostlist = get-VMHost
    Disconnect-VIServer *-confirm: $false

    {foreach ($string in $hostlist)
    SE connect-VIserver-server $string - user 'root' - password "abcd".
    }

    $vmlist = get - VM

    {Foreach ($vm to $vmlist)
    write-host 'Shutting down $vm' - blue BackgroundColor - ForegroundColor white
    $vm | Stop-VMGuest-confirm: $false
    }

    Sleep 10

    {foreach ($path in $hostlist)

    Restart-VMHost $path - force - confirm: $false
    write-host "$path restart" - blue BackgroundColor - ForegroundColor white
    }

    I suspect that the message could be caused by the parameter that you pass to the Restart-VMHost cmdlet.

    You use the retrieved by Get-VMHost VMHost object when you are connected to the vCenter.

    You can try this part of the code as follows

    ....

    {foreach ($path in $hostlist)

    Restart-VMHost $path. Name - force - confirm: $false
    write-host "$path restart" - blue BackgroundColor - ForegroundColor white
    }
