XZ291UA: dv7 - 4260ca - failure of the adapter?

Hello.

I think that my adapter has failed, but before ordering a new, I'd be really grateful some advice...

The symptoms are

1. works with the battery

2. does not work without battery

3. the battery is not

4. the light next to the port on the adapter when everything is connected (so I don't think that the problem is the power cord)

Idea?

Thanks a lot for your help.

  • Power failure causing AC adapter

    As indicated whenever I Plug and on my adapter on power point, there would be a power failure, and the trip is changed. What is the problem? And is covered by a warranty? My warranty 3 years on local warranty site, including the part and the work that is still valid with the exception of the battery (which is only a year)
    Thank you.

    Yes.

    If it trips the circuit breaker for any outlet plug in, then it is defective and a fire hazard. I do not recommend using again.

    The power adapter is also a replaceable unit of warranty. Contact HP for warranty repair.

    Please perform steps listed to find out if it is a hardware or software problem below:
    1. remove all cables and devices, disconnect them and try to turn on the device
     
    2. check the LED light situation and ensure the action of the spring button / stop is normal
     
    3 Exchange with a well known power cord and the AC adapter
     
    4 Pack no adapters are available, check if the power adaptor is slightly warm
    Note: This will give us an indication that the power adapter could be good
     
    5. do you know if the laptop was in battery or power adapter when you used the last time
    Note: Make sure that there is no spill of liquid or cutting
     
    6. check if the Port of the AC adaptor is loose/broken

    -Jeremy

    Hi, Jeremy:

    You can call HP and see what they have to say about SATA II/III, but I think that if your laptop is not under warranty you could get pay for technical assistance.

    I have never installed a secondary HARD drive in the notebook, so I don't know what port you plug the other end of the cable in.

    The problem is there are 2 configurations dv7 is why there are 2 different cables to the HARD drive.

    I think this post might answer your question: read the info of the carloprimo. It shows where to connect the other end of the cable into your model.

    Finally, it is my pleasure to be able to help the people on the forum free HP.

    I have problems to restart of Yosemite, after power failure during the new backup, and now HD is also blocked.

    I tried the holding of 'command-r' and 'option' to see if the problem can be resolved or try any boot from a boot disk, my old backup, USB function start - but after a slow long process it all just stops.

    There is software on my HD that I don't want to lose by simply reformatting the computer, because I am now in a different country, far from my house, which is another problem of the Apple Store, to reinstall my OS from Yosemite on the www.

  • Airport express to extend wi - fi using the adapter but NOT extreme airport

    Hello

    I am looking to buy an express airport in order to listen to music through my stereo and also create another network wireless upstairs in my house.

    My question is, I currently have no apple down wireless router and I have connected to a line adapter with an adapter of the power line on the floor. If I connect the airport express base station to the adapter on the floor, I'll be able to create another network on the floor as well as the flow of my music, even if the router that comes from the connection is not apple router?

    Thank you

    Andy

    If the floor of the Airport Express will be connected via the WAN port using a regular power adapter ethernet cable carrier online and will be in Bridged mode, you can create a wireless network to the floor. Not bridged mode, you can see double-NAT issues, which should be avoided.

  • coaxial cable of the adapter cable ethernet to the airport

    where can I find a coaxial cable to the adapter cable ethernet to my Airport - have time warner line coming into the House but need to ethernet adapter to use the airport for router and modem

    Unfortunately, a co - ax for Ethernet card will not help you.

    The reason is that the Apple AirPort routers do not have a modem on board, you therefore need an external modem separated if you want the airport to be able to provide Internet access to clients connected.

    Co - ax cable connects the modem. Then he use an Ethernet cable to connect the modem to the "O" WAN port on the router from the airport.

    Check with Time Warner for recommended modems that are compatible with their service.

  • Interesting solution of failure of the fans occasionally cold start?

    Interesting solution of failure of the fans occasionally cold start?

    Normally I do a reset of the SMC, sometimes it's the solution.

    When kick cooling fans as soon as I start my cold iMac, I just quickly swivel the iMac slowly from right to left and the cooling fans have stopped.

    Strange?

    All the answers?

    Note: I use an iMac 21 inch end 2013-2, 7 GHz Intel Core i5

    Thank you in advance for the answers.

    This sounds like a sensor loose or pinched wire.

    You may be able to see the problem of sensor or sensor wire with the diagnosis of Apple to test or a third party temp. followed by the application, but the best would be to book a service appointment at your local CENTRE.

  • Opening, Firefox screen turns blue, not a failure, just the entire screen is blue.

    There isn't a "Blue Screen of Death", the site does not load and the Firefox screen becomes completely (without search left bars) tinted blue color that uses Windows 7. I'm guessing it's related to an add-on, but not sure. Here's a picture: http://i1176.photobucket.com/albums/x328/Deathtomyfoe/MozillaError.png

    Hello Thomas_Hunt, can you try to start firefox in safe mode by pressing the SHIFT key during startup of this and see if the problem occurs there too? Maybe a theme or hardware acceleration intrudes here...

    If safe mode does not work, you can try to disable hardware acceleration in firefox > options > advanced > general and or disable addons that could cause the problem. It would also be interesting what graphics hardware (description of the adapter, driver date and version of the driver) you use - you can access this information in firefox > help > correct information to the bottom of this page... Thank you

    Troubleshoot extensions, themes, and issues of hardware acceleration to resolve common problems of Firefox

    edit: another user, we discovered that this could be related to malware, you could see if you have the same addons installed, remove/disable the & run a scan of your system with security software - see https://support.Mozilla.org/en-us/questions/940393#answer-377118
