HP Pavilion dv7-1240us: Pavilion dv7-1240us | Does not - battery LED flashes constantly

Greetings!  I bought a laptop HP Pavilion DV7-1240US.  When the battery is connected to the laptop and the power adapter is plugged in, the battery light flashes continuously in intervals of 1 second.  When I take the battery, the laptop power not on at all.

I did a hard reset of the laptop, I checked the ram slot connections, deleted and reinstalled the hard drive and still can not get the system to work.

When the battery is connected to the laptop, if I press the power button, while the battery LED is lit, the system will try momentarily in power all keys quick adjustment on the Strip at the top momentarily illuminate, and he tries to switch to the top, only to die as soon as the led turns off.

Does anyone have an idea what could be the cause of this? I would like to point out that the caps lock and caps lock Num-buttons Flash at all, and there is no beep sounds to speak, so I am at a loss.

Any help would be GREATLY appreciated!

Thank you!

  • HP Pavilion dv7t-3000 does not start

    My HP Pavilion dv7t-3000 does not start. I checked this article: http://support.hp.com/us-en/document/c01732674

    According to who, the error condition is: 'non-functional CPU.

    So if I buy a new processor and disassemble the laptop and replace the processor, it will fix the problem?

    Perhaps, but it is much more likely to be the motherboard. If the motherboard is bad, you can't trust the blink codes that it generates. Failures of the CPU but rarely occur. Motherboard failure happens all the time.

  • DV7-1232NR does not start

    DV7-1232NR does not start. The lights above the keyboard, the dvd player makes a bit of noise, then eventually the lights Verr Num and caplock do a slow blink continuously. As I understand it, flashing for default codes flashing one to six times, and then exit.

    Hello

    As you have no doubt already concluded, it would look like a significant failure of hardware, in particular given the fact that there was no change when the memory has been removed completely.  Unfortunately, the most likely component is the video chip which really means a new motherboard.

    The only other possibility might be interesting to try is to remove the module WLAN (Page 51), leave the battery and try to start Notepad on the entire sector.

  • The sound on my HP Pavilion G6-1a19wm does not work

    Hi the sound on my HP Pavilion G6-1a19wm does not work.   His "only" works when you use the audio plug with external speakers.   I tried to uninstall the driver, update the driver, microsoft fix - it and troubleshooting steps.  audio device present in the Device Manager and supposedly working properly, mute is "not"on."  visually everything audio related things suggest that the audio is fine and troubleshooting finds no problem... what else could it be?

    Hello

    Try the following.

    Download IDT Audio Installer on the link below and save it in your downloads folder.

    http://ftp.HP.com/pub/SoftPaq/sp55001-55500/sp55036.exe

    One time finished, open windows control panel, open Device Manager and open sound, video and game controllers.  Right click on the IDT device and select uninstall - also, you should get a command prompt to delete the current driver, check the box allow this and then proceed to uninstall.

    When you're done, shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

    Allow Windows to fully - charge it will automatically load an audio driver, but let just this complete.  Then open your download folder, right-click on the IDT Installer and select "Run as Administrator" to launch the installation.  Once this done, do a right-click the speaker icon in the taskbar and select playback devices.  Left click 'Speakers and headphones' (or speakers/HP) once to highlight and then click the Set Default button - check if you now audio.

  • Recovery Manager HP does not recognize my flash drive!

    My computer is HP Pavilion p6 desktop computer - 2317c, running windows 8.

    I am trying to create a recovery media and have a 32 facet of Cruzer Sandisk of Go that I intended to use for this. Unfortunately, Recovery manager does not recognize the flash drive... it never appears in the menu at all. The drive appears when I click on the computer icon in the section files, with no problems at all, as you can see.

    I have not created a game of recovery media, and it shows not enough space error, he just lets it appear at all!

    What can I do to fix this? I really want to do a recovery set, to prepare for a visit to the demon responsible for foulups visit.

    Hi Savvy2,

    SanDisk has changed the firmware in their most recent products so that the USB appears as a local drive and not as a removal media device. Keys older HP Recovery Manager on this information, and that's why the HP Recovery Manager is not recognized your USB key.  Review of the information that has been compiled by Erico below.

    I would like to point out something that you may not realize: Windows 8
    has two interfaces; the modern/Metro Interface (which may be all the)
    you have looked at) and the traditional desktop Interface. You can use
    one or both. This traditional desktop Interface is almost
    identical to the interface of Windows 7. the biggest difference is that
    There is no Orb start clicking to bring up the start menu.

    But note that you can get the ORB start by using one of the many
    third-party programs, are free or very cheap (the classic interface
    http://classicshell.sourceforge.NET/ and debut8 to
    http://www.stardock.com/products/start8/; my personal preference is
    Debut8, but they are both very good).  And goes from an interface to
    the other is very easy; There are several ways, but simply by pressing
    the Windows key is perhaps the easiest.

    Just install one of these two and using the traditional desktop computer
    interface may be a better choice for you than going to Windows 7.
    I use Windows 8, almost exclusively with traditional workstations
    the interface and with 8 Start installed. If you were to look at and use
    my computer, you may have a hard time realizing that it is not
    Windows 7.
    I also recommend to read "how to make Windows 8 or 8.1 watch and.
    Want Windows 7 "to http://www.howtogeek.com/elk/298/45121/4206
    I can't address the issue with your games, except to say that
    whenever you move to a new version of the operating system, some of
    which is used to run on the former does not work on the new. And it's
    much more likely with utilities and games with companies
    applications.

  • C-level extensibility does not work in Flash Pro CC

    It is now impossible to create a native C/C++ library and export C functions that can be used by Flash commands for example. The sample "SampleDll" C-level extensibility project now does not work in Flash Pro CC as well:
    http://help.Adobe.com/en_US/Flash/CS/extend/WS5b3ccc516d4fbf351e63e3d118a9024f3f-7783CS5.h tml

    http://download.Macromedia.com/pub/Developer/Flash/Flash-Pro-samples.zip

    When Flash Pro CC is installed the "< user_home_dir > / AppData/Local/Adobe/Flash CC / < language_code >/Configuration/external libraries" already contains a dll that exports the MM_Init and the MM_Terminate, so presumably the extensibility of level C is still available, but its likely new use may not yet be documented.

    Hi Pierre,.

    C-level extensibility is supported by Adobe Flash CC just that you need to build the 64-bit version now. What is the error you get? You can try the link of file sample shared in my post above?

  • What should do? IE 64 bit does not work w/flash 10.0 or 10.1

    What should I do?  IE 64 bit does not work w/flash 10.0 or 10.1

    I (we) have the same problem. We do not wish to use the 32-bit browser. It's time to finally get to the next step and use all 64-bit applications.

    I cannot help thinking that Adobe delays this compatibility on purpose for some reason any. This is absurd.

    It will cost them market share in the affirmative. It's frustrating we're talking everywhere on the Internet.

    Adobe, you feel that you have reputation. Whether you like it or not, windows 7 64 bit is hot right now and is widely sold in every store in the small and large computer.

    You repeat for 3 years that you "will have a 64-bit version in the next release. Is not what some might call a lie? Of course I do. It is causing you to lose credibility because you're not be truthful.

    Hello

    I have a HP Pavilion dv7-4065dx laptop with Windows 7 64 bit that won't start or go to the Bios screen.  When the laptop is turned on, you hear the fan from the system start, start button / stop brighter lights and the caps lock button starts to Flash continuously once every three to four seconds.  The activity of the disc is also light on but with no flashing red.  No changes have been made to the laptop and it worked perfectly well a few hours earlier.  I tried the hard reset of the computer and the reinstallation of the memory cards, but the laptop would be still not start.  Any help to determine what the problem is with the computer would be greatly appreciated.  Thank you.
