Light ambient TouchSmart IQ816 no longer works

About two days ago, I got a weird error that says that the pc has not turned off properly.  It starts fine, performed tests, defragmented.  Today, I realized that the ambient light does not work.  A system restore before the weird error.  Still no light.  Tried to reinstall the slight update, still does not.  The card mother tests all the passes, nothing shows an error.  Just this light is out.  The switch on the side of the pc won't turn the light and the keys on the keyboard so that it won't either.  Is there anything else I can do?  Or anything that could tell me why it doesn't work?  Just burn something?  I don't really have any idea.  I'm afraid just because it happened with connection to my pc network earlier in the year where I had to buy a usb thing just to connect to the Internet with this pc.  Can be burning things simply on the motherboard, and it does not appear in the diagnostic tests?

My ambient light is finally back.  I think it's the bug with NVIDIA drivers.  I've updated my video driver this week, and once I did a true reboot with the pc completely turn off and then turn it on again, the light finally returned.  I was very surprised, it was off since October.  So if someone has this problem with the ambient light doesn't work do not try to update on the latest NVIDIA video driver, NO area of HP update, I had the driver on a site driver on the net.  The HP here isn't the newest one.  Looking for latest drivers in January or February of this year.

  • Light ambient 5.71 cursors not working do not.  Develop Module

    I am currently using a MacBook Pro with OS 10.8.5.  I used the room light 5 during about 2 years.  The sliders just stopped to change the images after my last import of 50 + photos.  I did have a problem with until last week.  What can I do to remedy this situation quickly?  Please let me know.  The images appear, but the sliders do not change the quality of the images.  I don't want to uninstall the program.  Are there patches, I can use for my cursors to return to life.

    I wonder if you are in the adjustment brush, graduated filter or Radial filter tool - these have familiar sliders, but they do not affect the image until you define an area of the photo to be affected. Press the Esc key or twice - if you were in one of these tools, it will close. Do not forget that you are using the sliders in the basic Panel or other below.

  • Script no longer works when I remove beep

    I am trying to create a script that will get the number of words in a Pages document, and then save in a Numbers spreadsheet. I am a novice coder and until about 6 hours ago, I got this script, I had never even heard of Applescript. But with trial and error, I came up with this script to display the number of words in my document:

    say application 'Finder '.

    activate

    Set myFile to alias "user: boldfish98:Desktop:Aviator alias.

    myFile Open

    beep

    say application 'Pages '.

              tell front document

    say text body

    the value myCount to count words

                   end say

              end say

              close front document

         end say

    end say

    myCount

    (I posted only myCount to make sure it works, ultimately, it will not display). This script was working fine so I started on the part that would put the number of words in the worksheet. I have made good progress on this front, I noticed a really annoying problem with the above code. When I was working on this part I put a bunch of beeps at different points that I would like to know when the code stopped working. I deleted most of them, once I knew that the code worked and I was ready to move on to the next part. But when I tried to delete one of the beeps (the only one left in the code that I put in this post), the script no longer works. I get this error in script, emphasizing "word count":

    Pages has been an error: failed to get document 1. Invalid index.

    It did not make sense to me so I checked over and over again to make sure that I had not deleted anything else, but it was just the beep. When I put the beep back in at exactly the same place the script developed, when I pulled it again I got the error. Even with my extremely limited experience I am sure that something is wrong and my coding script should not to beep to run. I looked through the internet to see if anyone else has had this problem and found nothing, so I started to browse all the posts here the applescript, and I saw someone ask if error a poster that's happened on the compiling or running. I know type of compilation of what means but I do not know how it is applied to the script editor. I guess this is what happens when I press on save and the light purple text gets formatted with 'say' in "BOLD", "application" in Blue italic and so on. I don't get the error, then, it happens when I run. Sometimes when I run the script with the beep I always get the message, so I think that there could be something wrong with the way I count the words (if you know it please report it), happened only 5% of the time that I run with beep. And it happens 100% of the time when beeping is not there.

    Here are the things I've tried (none of them worked):

    -copy and paste the code without the beep in a new document from the script editor

    -Retype the code without the beep in a new document from the script editor (I got the same error but when I added in the beep it worked)

    -restart script editor and pages

    -restarting my laptop

    -Commenting on the beep

    -replacement of tone with screen of dialogue ("Hello world!")     the dialog box display worked, but after I clicked OK in the dialog box the script stopped running, and I got the same error

    -remove the beep and but leaving empty line

    -remove the beep and the empty line

    -change slightly the other parts of the code as a substitute "document before closing" by "quit".

    a lot of these I didn't work, I was just desperate. I also didn't expect the success of my script a beep. I feel like script editor knows I'm brand new to this and so he's trying to trick me. Any help would be greatly appreciated. And if you know other ways I could improve this code, I'm all ears. Thank you!

    Also I just got this new laptop as a week ago, so I don't think that this problem is related to my software is obsolete.

    When I tried cela it is line 3 that caused the problem; It should read

    value alias myFile "alias Users:boldfish98:Desktop:Aviator.pages".

    As you, it did not work even with the beep; with this change, he worked with and without the beep. Other than that, "beep" takes back you to the inventor, but I don't see why that should be a problem.

  • Satellite S50t-B touch screen no longer works

    Hello

    My partner bought a S50t-B Satellite probably 5-6 months and everything worked perfectly, until she had a few updates to windows that has happened, and now the touch HID compatible drivers are apparently disabled in Device Manager?

    The touch screen no longer works, and I've pretty much exhausted all the options I could think.

    I tried to reinstall windows, apply all updates via the service center, I can't find the drivers for the touch screen on the support Web site downloads section and the bios etc is all to date.

    I was hoping someone could shed some light on how to proceed with this issue, since the main reason, she bought there the touch screen function.

    Thanks, Keegan

    I don't have any idea what system you have installed, but if the laptop was equipped with touch screen, additional drivers for touchscreen are not necessary.
    If touch screen is working properly, the Windows (Win 8.1) should detect it automatically.

    What Satellite S50t-B-ooo do you excatly?
    From my point of few, the laptop must be set to settings factory just to check if its really a software related issue... so I wonder why you do not use HARD drive recovery or recovery media to restore the laptop to factory settings?

  • Equium L20-197 no longer works

    Can I invite you for a little help on this one.

    I received an Equium L20-197 that no longer works. Not having is not the chance to see never work I'm not sure on a number of things.

    It is totally dead, with the power supply connected there is no sign of life, no power, light nothing.

    I know there are a lot of things it could be.

    This is should it lights up while there is no battery connected, only the power supply plugged in?

    If she will be so at least I can pass a battery problem, yes the battery is perhaps still defective, but this would mean that the motherboard is probably us. If she must have a battery equipped, even a plate, then it could be the battery.

    Just try to work through step-by-step.

    Any help much appreciated.

    Hi mate,

    hehe, looks like a technician is here. :) It s a very good idea to do it step by step because every good techno acts like you. So I do, and it has helped me several times.

    Regarding your question: the battery must not be connected to start the machine, so if the machine start-up even won´t just with connected AC then you can be sure that there is a serious hardware problem.

    In this case, you can remove all (disk, CDROM, etc.) and try again. You can also share the adapter of the ca and the RAM. Thus, if the won´t still machine starts, then contact an ASP (Authorized Service Partner) and ask for a review of health/repair of equipment. It would be the last resort.

    Here´s a link to find the nearest ASP in your country:

  • Portege M800 LED button no longer works

    Hi all
    the LED button, that normally turns on/off switch lights up and the led lights up next to the touchpad no longer works.
    When pushing blinks for about 1 second, then turns off.
    Thanks for the replies

    May I ask what operating system do you use?

    As I m not wrong not you mean the control of Toshiba button next to the switch.
    Am I wrong?

    According to the M800 model, you can use this button to mute the volume or to turn on the lighting in the touchpad, logo of the brand and the keys and.

    The M800 is unknown to me, but I know that some other series of portable supports an option in the BIOS called LED lighting. You can turn it off and turn it on.
    Please enable it in the BIOS and save the settings.

    In addition, you should check the settings of the Toshiba control utility. Maybe there is an option that could help to control the properties of the button.

    Last but not less a new reinstalling driver could solve this problem.

  • HP Compaq 6910p touch controls no longer works...

    I installed windows 7 Home Premium 32 and also installed Snow Transformation Pack 1.5. I have used and deleted some kind of buttons 1, 2, 3, 4. I did not restore point before using it. Now, I want to use the original Windows 7 without additional extensions. Everything is almost OK except touch buttons. The volume upward, the volume and mute no longer works. When I touch the buttons, they are light, but without result.

    Can someone help me with this kind of problem. Is how to configure these touch buttons (enabled/disabled)?

    That you have a solution, but I have to say that it did not help me.

    I found a solution of forum in notebookreview.com. Very simple solution:

    "Shut down the computer, unplug the adapter, remove the battery and hold the POWER button for about 45 seconds, THEN reinsert the dough and all and start the computer" and it helped!

    Hopefully it helps someone else too...

  • bar who control the volume no longer works on nb dv6-1341el

    Hello, I have a computer laptop dv6-1341el who has never had any problems so far, but now the bar which lets you adjust the volume and the wireless light control that touch seems to not want to work more, that is, the display is okay, but as with the touch controls no longer work. I have not changed anything in the configuration, I just used a pair of headphones, and since then has disappeared. I don't believe in coincidences, then, can anyone suggest me what I have to reinstall drivers or programs, before thinking to format the pc?

    A hard reset works sometimes. Disconnect all external devices first.

    battery and power cord 1 / removal

    2 - Press the power button for 30 seconds

    3 reinstall only the power cord for the first start.

    4. turn on
