Close out help and support window. Locate the the recovery manger and  Click yes in prompt window if displays then select Microsoft System Restore in next two screens click on next You well eventually end up with dates listed choose a date before this event occurred then click next follow all command promts.  Ounce recovery point has been completed run your antivirus software. Then do a PC Tune Up.  Go to your control pannel and open up Performance Information and Tools  select Adjust power settings on the right hand side. Then select Choose when to off the display. Next window switch all boxes to never. You will never have to worry about this ever again.  On top of that the issues you face trying to wake up the computer from sleep mode.

  • I have a touchsmart 520 pc and installed windows 8 but it says the hp software is not compatible

    I am running windows 8 on an HP TouchSmart 520 but it says the HP Software is not conpatible with windows 8 is it possible to get a compatible version

    When requesting assistance, please provide the complete model name and/or product number of the HP computer in question. HP makes hundreds of TouchSmart models that are all different. Without this information it may be difficult or impossible to assist you in resolving your issue.
    THIS is HP's position on Windows 8 support and any HP computer not supplied with Windows 8;
    Not all Windows 8 features may be available on all PCs.
    Your particular experience with Windows 8 will be determined by the capabilities of your PC.
    HP is providing upgrade instructions and drivers will be available for most Windows 7 systems sold after 1st October 2011.
    If you want to restore the original operating system after upgrading, you must create HP recovery media before you upgrade.
    Please note that if you purchased your system prior to October 1, 2011, HP has not tested these PCs or developed Windows 8 upgrade instructions or drivers for them. Upgrading such systems may be difficult or impossible.
    and
    Important information regarding additional limitations and requirements;
    Screen Resolution Requirements
    Limitations with DVD playback software
    Limitations with Blu-ray playback software
    Limitations with TV Tuner software
    Secure Boot & other UEFI dependent features
    Secure Boot & other UEFI dependent features
    Limitations with touch screen capabilities
    Windows 7 PCs with touch screens will not have full Windows 8 touch capabilities after upgrade.
    HP PCs with touch input hardware designed for Windows 7 will provide a comparable experience for only two touch point applications after the upgrade to Windows 8. HP Windows PCs with touch input hardware will not support Windows 8 applications that require more than two simultaneous touch points.
    Additionally, Windows 8 edge swipes may not be available due to the recessed bezel on HP touch systems shipped with Windows 7.
    HP TouchSmart Magic Canvas and HP TouchSmart applications are not compatible with Windows 8 and must be uninstalled before upgrading. Note that content created using the TouchSmart applications such as Graphitti will not be available after upgrading.

  • TouchSmart 520 Windows 7 Home premium Problems after critical updates

    After my TouchSmart 520 auto ran critical updates on 13 Feb 2013,I cannot connect to Internet at all.It was still able to connect to my home wireless network.
    I did a systerm recovery, to restore up to just before the critical updates on 13 Feb, then it's able to connect to internet. After that, it auto ran critical updates 2 times, and the same problem started.I have done the system recovery again and  now turn off the downloading and installation of critical updates completely, but this should not be long term solution.
    Has anyone encounter same problem or is able to help me on this? What else do I need to do?
    Appreicate any help.TIA!

    Hello sgcosimo,
    You’re not able to connect to the internet after updates have run. I’ve had that happen before and usually Microsoft will send out an update that fixes the problem a few days later.
    You can try to run the updates again to see if you still get the error.
    If you’re still not able to get online, go into device manger and uninstall the Wi-Fi adapter and restart the computer.
    Here is a link to uninstall the adapter.
    Let me know if this helps.

  • Can I connect an external monitor on an HP Touchsmart 520 PC, using an HDMI to USB converter?

    I am attempting to connect a second monitor to my HP Touchsmart 520 all in one deskop PC, which does not have a VGA or HDMI port. The monitor has an HDMI cable, to which I have connected an HDMI to USB adaptor and connected to one of the USB3.0 ports. The monitor is not getting a signal. Does anyone know of a solution?

    This article will walk you through the process.

  • Can I add a second monitor to a TouchSmart 520-1070?

    Can I add a second monitor to a TouchSmart 520-1070?  Can it be done through a USB port with a USB to DVI converter?

    To connect your HP TouchSmart 520-1070 desktop computer to a second monitor or a TV, you will need to purchase a USB-to-video adapter. I recommend the eVGA UV Plus+ 19 USB-to-Video Adapter, however many of these other USB-to-video adapters should also work.
    FYI... with a touch screen, you can only "clone" the desktop... trying to "extend" the desktop may cause problems using the computer.

  • Cannot play any video (even youtube vids) on my HP TouchSmart 520 with Windows 8 in Metro Mode.

    HP TouchSmart 520 PC
    Windows 8
    Just upgraded from Windows 7 to Windows 8. 
    Upgrade was uneventful.. went very smoothly.
    Problem is now I cannot play any videos in the new Metro Mode (I tried using various apps... Video, youtube player, etc).. not even youtube videos. 
    However, when I select Desktop mode.. everything still works fine.
    Any idea what is wrong ? 

    Hello WongKO:
               Welcome to HP's forum. I do not know much about Windows 8. Reading this fact sheet it says that you need to purchase the media software and upgrade to Windows 8 pro. This fact sheet should guide you. http://www.windowsupgradeoffer.com/en-US/Home/Faq? Windows 8 system requirements section.Will DVD playback work after upgrading to Windows 8? This one is in general section. Will installation media be available for purchase? Back to Windows 8 requirements. Is Windows Media Center included in the upgrade to Windows 8 Pro? Least you are able to watch videos in other mode until you figure out what is best. Good luck frrw. Ounce you have figured out the software purchases you should post it to help others out. My computer is to old for upgrade. No drivers were made for it.

  • HP TouchSmart 520-1047c Webcam Issue

    My webcam has gone MIA. My Chrome Hangouts tries to launch and place a video call and reports it could not access my video camera.
    The Camera HP High Definition 1 MP shows in the imaging devices of my Device Manager. I have uninstalled and reinstalled the device there it is using the latest Microsoft USB Camera video drivers.
    I went to the Touch Smart Webcam application and launched it from there and particle reported several missing files that it uses for special effects. That didn't stop the camera from coming up and working OK.
    I then went to the HP website and followed their webcam troubleshooting guide. It reccomends that you  reinstall the webcam software using the Recovery Manager. So I deleted the existing Touchsmart Webcam software package from the Programs and Features Contro panel app launched Recovery Manager and Selecte HP Webcam software to be reinstalled. The install seemed to fo well no errors were reported. My problem is I now can't find the TouchSmart Webcam softare application to launch the webcam. Recovery Manger thinks it is installed as it asks be to uninstall it if I try amd reinstall it.
    How do I find where the PC installed the software. Ir is not in Program Files(x86)/Hewlett-Pacard/Touchsmart where all the other TouchSmart aps are located.
    Any ideas where I can find this or force the recovery manager to install it again?
    Thanks in advance...

  • Flashing bars intermittently appearing on edges of Touchsmart 520 screen

    I have an HP Touchsmart 520 PC which is about 2 years old
    Product Name: 520-1061uk
    Product Number: H0N10EA#ABU
    Operating System: Windoes 7 Home Premium 64-bit Service Pack 2
    Recently white flashing bars have started intermittently appearing at the edges of the screen. I have run diagnostics and all pass OK. Have attached a couple of pics showing the flashing bars as the HP diagnostics was loading below. 
    I presume this is a hardware failure but could anyone tell me whether it's most likely to be the screen, motherboard or video cable?

    I have read your post on how there are flashing bars intermittently appearing on the edges of Touchsmart 520, and I would be happy to assist you in this endeavor!
    Since the lines on the screen are likely to have been produced by the graphics card overheating, I recommned following this document on Reducing Heat Inside the PC to Prevent Overheating. This should help clean out any excessive dust, allowing the fan to cool the desktop effectively.
    If the issue persists, I recommend contacting our technical support at 1-800-474-6836. If you live outside the US/Canada Region please click the link below to get the support number for your region.
