• Pavilion dv6tse - 3100: laptop screen turns sometimes and sometimes does not work

  When I turn on my laptop, there is a chance that the monitor does not light. What to do when this happens is I turn it works again and again until the screen lights up finally. When it lights up, it works very well and stays on until I turn it off and then the problem can repeat once again. Notes: I tried to connect to an external monitor and the TV via HDMI, and there is no signal when the monitor won't turn on, but works perfectly if the monitor does not light. If the screen lights up or not, everything else seems to work fine as I can blindly off keys and hear the music of connect/disconnect.

  Please help me!

  Im trying to open the tutorial of 23 minutes on how to use different tools in photoshop and it continues to come with unable to resolve the DNS servers worked fine yesterday? Ive had creative cloud on my laptop for a week and not yet able to get past the basics make me very frustrated.

  I guess you meant the links when you open photoshop CC. I tested all four videos of the 23 min tutorial and they all played fine. If something between you and adobe does not work correctly.

  • Check that your firewall is blocking the net. Try to access youtube videos and see if they play very well
  • Go to the adobe tv site and try to play one of the videos here. Adobe TV
  • If youtube plays very well and adobe tv does not work, next is to check if you have flash installed. Some videos require flash, others are html 5. Sorry that I could not confirm what player has been used for this tutorial. I think that html 5 but not sure.
  • Next is to look at the properties of your browser and check multimedia settings are not disabled if it y in a. (this is totally dependent on the browser)

  Pilots may also need to be updated:

  Control Panel - device - SOUNDS - look for HD Audio Manager - Mine said RealTek high definition
  Audio (this is an example and you can have an other name/maker).

  Make sure you write down the description and model double click top - tab drivers - write version. Now
  Click on update drivers who cannot do anything like MS is far behind the certification of drivers. Then RIGHT
  CLICK above and UNINSTALL - REBOOT - this will rebuild the driver stack.

  If your driver shows 06 you have the default windows and part of the question.

  Go to the system manufacturer's website and get the latest Audio/Sound drivers - download - SAVE - go to the place where you
  Put them - right click on Reboot - RUN AS ADMIN -.

  Check the Version tab of the driver in the Device Manager as the restoration of the sound card drivers often
  and then install the latest version. Restart and check after each test, not
  rare to have to run the pilot of 1 to 4 times or more. Just the version make sure you
  installed shows upward on the tab of the driver.
  
  Then navigate to the site of the manufacturer of the device and search for the drivers more recent and repeat the installation procedure.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  Hello.. I have laptop (hp probook 4520 s), keyboardis does not. only the letters 'B' and 'n' How do I reactivate? because when I use a keyboard external usb it works? Help, please

  Helder salvation,

  Did you of recent changes made to your computer?

  We will reinstall the internal keyboard drivers and check.
  
  a. click Start, type Control Panel in the search box, press enter, click System, click Device Manager, click on keyboard.
  b. you should find the internal keyboard part as well as any external keyboard used.
  c. right-click on the keyboard integrated in the list, click on uninstall.
  d. unplug the external keyboard.
  e. restart the computer and check if the keyboard internal works.

  Since the external USB keyboard works, if drivers did not fix the internal keyboard problem, I suggest you to contact the manufacturer to check if there is a hardware problem.

  Hope the above information helps.

  To run all the applications of the laptop or install download applications works does not error message indicating that the application is not valid "win32.exe or win32.application.

  Hello m.velentino,

  Not sure if you are still having the error message isn't valid win32.applicaiton.

  Get the error: not a valid 32-bit application can have several origins:
  I have listed some of them below.

  The file is corrupted, bad or missing.
  -If the hard disk is damaged or hurt it cause work programs to fail, either because not all data can be read from the hard drive the program is damaged on the drive. Run scandisk and defrag on the hard disk to check for potential errors.
  -If you run the program from a shortcut on the computer, verify that the program is still on the computer. In some cases if the program is no longer installed on the computer, you can get this error.

  File is not designed for your version of Windows:
  -If you try to run a program that is not designed for your version of Windows, you can get this error.
  -Although many old programs designed to work in older versions of Windows will work with new versions of Windows, unfortunately, not all programs will not work.
  -If the program is an MS-DOS program more former start program or Windows, you can get this error.
  -If the program is designed for a 64-bit version of Windows and you are running in a 32-bit version of Windows, it will not work and generate this error.

  File is a virus, worm or other malicious program file.
  - This error can be generated by a file that is a virus, worm, Trojan horse or other type of malware file. Often, this will result because the antivirus installed on the computer will not allow the file to install or run. Try to analyze the file to check, it is not a virus or infected.
  -If the file has been checked and is clean, it is always possible that the virus protection program or a another program installed on the computer is at the origin of questions during installation or execution of the program. Start the computer in Mode safe and try to run the program. start the computer in Mode safe will be that nothing is running in the background that could cause this problem.
  
  Hardware incompatibility.
  -If you get this error during the installation of a program, it is also possible that the CD-ROM drive or the drive that you are installing the program from is not compatible with Windows or has drivers that are not compatible with Windows.
  -Download the latest drivers for your CD player or other of the manufacturer of the computer or the manufacturer of the equipment. (Microsoft does not pilot for other materials)

  Let us know if these suggestions help you.

  Are there other downloads or solutions that will help w / this problem?
