HP Envy dv4 Notebook PC Touchpad not responding

Hello

All of a sudden I lost my touchpad. It is no longer allows her to follow my mouse movements. The power toggle button touchpad seems not too much work. I can't turn or no more. I rebooted my system a couple of times with no result. Also tried to uninstall Synaptics Pointing Device Driver and later installation of the latest version without any positive impact. Will be great if you happen to have any suggestions.

Hello

It is always interesting to try the following.

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.

Kind regards

  • HP Pavilion dv4 Notebook PC: touchpad scroll function not working after installing windows 7 (64)

    After a complete hard drive failure, I installed Win 7 everything works, as far as I know, except scrolling on the touchpad. I went through all the troubleshooting I can find.  The last one I tried was in the Control Panel, mouse and look for the details of the touchpad. It is not listed there.  I can't find a driver to install HP and Driver Downloads. Where can I find a driver for the touchpad with scrolling? The only thing listed under the mouse in the menu of device driver is a PC mouse.

    I'm sorry that the link of the page didn't work.  HP has problems with the website support, and even for me at times, page links do not work.

    As for the installation of Windows 9, how to acquire that is to order the HP recovery media. It is a DVD and CD set that will erase the hard drive (removing all data, applications and settings, reinstall the original OS, drivers and utilities for HP.  You get these by contacting HP Customer Service.

  • Equium A100-027 touchpad not responding

    I have an equium a100-027 and today the touchpad was funny.
    For example, I went to move and sometimes it wouldn't be no move, moved very little, or when he moved quickly moved to around to the same place that it was before.

    I assumed that maybe it's just that my computer has been used too much memory or something. But then later, it no longer responds. I restarted my computer and the same problem, it does not move.

    Before anyone suggests, I in fact checked all the settings for it. I know there is a shortcut (fn + f9) to turn it off.
    However, I already checked and it is activated.
    I am falling quickly with this computer, six months old and already had two problems with it.

    Anyone can suggest a way to solve this problem, or should he be returned to be repaired?

    If it must be returned, how should I do this?
    I bought of Dixons, and when I came down to them with my last number, they said they have no responsibility and I had to call "the tech guy".

    This ended up being A £1.50 tech support number overcharge, which I'm not call again.
    This laptop has only 6 months, clearly under warranty. I don't have to pay who knows how much on a phone call just to get it fixed.

    Sorry if this sounds like a hangover, just in a bad mood with this computer at the minute.
    Thanks for any help! =-)

    Hello

    I see that you're desperate. Sorry to hear this story.
    But before you send this laptop to any point of service, you must reinstall the laptop with the Toshiba Recovery CD.

    This procedure will put the laptop to factory settings!

    If the touchpad does not work after reinstalling new contact ASP in your country.
    The service provider authorized in your country will be able to help you and if your warranty is valid, everything must be done for free.

    I can't believe that the appeal could cost about £1.5 because it s a common phone number.

    If you want to find the ASP please check this:

  • NB100 - bottom of 10mm of touchpad not responding is not in Windows XP

    Hi all

    I bought the NB100 Ubuntu version and have been very happy with it.
    Because I like to tinker, I installed XP on it to see how it would compare.
    So far, I prefer the version of XP, but I have a little problem, and I don't know if it is normal that the version of Windows?

    I have install the Synaptics driver, and the touchpad works very well except for one thing.
    The pad simply does not meet a vertical movement in the bottom of 10mm or more, even if it does not meet the horizontal movement.

    It is also very well - it's as if the driver thinks that the touchpad is smaller than is it supposed to be 10mm.
    I disabled all of the advanced features of the driver, with the exception of the vertical scrolling support (and I think + I tried just turning out too).

    Also has anyone seen this problem?
    Is it possible to 'train' the driver to recognize the lower part of the cushion?

    Thank you

    Graeme

    Could at least tell me that their NB100 (XP) does the same thing?

    It's OK on the default Windows driver, so I use that for the moment, but I have which gives me all the most useful features of the Synaptics software :(

  • HP Envy X 2 touch screen not responding do not when waking from sleep

    About half of the time when I wake up my HP envy X 2 version sleep 128 GB touchscreen is unresponsive. The mouse pad and the keyboard usually work but screen tousch work again until it is restarted.

    I took a peek in the Device Manager, while the touch screen did not work and I don't see under User Interface devices, I have a HID I2C device that has a yellow warning sign. When I open it under device status, it says "Windows has stopped this device because it has reported problems. (Code 43) »

    Someone at - it information on how to solve this problem?

    I had already tried to upgrade the Synaptics drivers and it does not solve the problem.

    I noticed several times that when I wake the PC from sleep that Google Talk would be stuck with about 40% of the use of processer according to the Task Manager. I usually just close and re - open Google talk and he would not stuck using the processor.

    A couple of days ago I closed Google Talk and did not restart the program, during the last 2 days I didn't only once when the touch screen has been non-responsive after waking up from his sleep.

    I've said before, but I had a similar problem with the rotation sensor, after waking up from his sleep, he would be intermittenetly does not work and I could also see in Device Manager that another I2C HID device was a code 43 error. Also since the closing of google talk, I didn't freeze the rotation sensor.

    Like I said its only been a couple of days, so it can always happen, but 2 days is the longest I can remember never go without this problem.

    mfhengst, you have google talk installed on your laptop?

  • Half of the touchpad not responding completely on my G56

    This product usually 2-3 minutes after the opening of the laptop and when he returns to hibernation / sleep. Literally half of the touchpad is completely insensitive to gestures, tapping and the lateral and vertical movements. The other half works very well. I reinstalled the drivers from the HP website. It will fix itself if I close the lid and open it again or reset the device in the Panel of Synaptics.

    Install the latest firmware (BIOS) from here and also to install the latest drivers here for your laptop touchpad and let us know if the problem persists

  • Pavilion Notebook M1Y13UA #ABL: clickpad does not respond immediately when you tapoterez

    Hello

    I have constant problems with the clickpad installed on my laptop. I can say that it is the touchpad/clickpad WORSE I've EVER had. It has been repaired twice by HP under my warranty coverage. First of all, they have changed a few son/cables inside and completely uninstalled Windows 10; Then, because the problems were still present, they installed a new clickpad, which changed the hardware. Some issues have been resolved, but others continue to be present.

    At this point, I'm trying to any parameters used for the clickpad, via settings-> devices-> mouse and touchpad-> properties of the mouse-> settings-> properties for Synaptics ClickPad ClickPad, very often, but not always, the clickpad is not responding when I type the first time after that I was doing something else. When I type the second or third time, I'm finally starting to get answers. In other words, whenever I type somewhere - to close a window, to follow a hyperlink, to place the cursor in a text, to select a part of a text, etc. - my first tap does NOTHING. I must repeat my cock at least once more before there is a response. I can type very gently or hard, it doesn't matter. It applies both to pressure alone to double tap. It is the same for the two fingers tapping.

    Pointing-> sensitivity feature is at its maximum. (If I reduce, the clickpad becomes even more that don't meet liked). Smart Sense functionality is almost extinct. (If I put it near Max, nothing changes.) Filter activation time option, which apparently blocks the clickpad for a certain period of time after you type, is zero. For the feature settings-> devices-> mouse and touchpad-> Touchpad (to help prevent the cursor to move accidentally while you type, change the time before work clicks)-> without delay. Turning or turn off of the button (on the clickpad) doesn't change anything. Clicks properly. All the drivers are up to date. All Windows 10 operating system up-to-date. When I attach my USB mouse, the mouse works fine, there is no delay in responses.

    I assumed that contacting HP for the third time will be not successful. Anyone have the same problem? If so, how to solve it? Other users seem to have had a similar problem (http://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Synaptics-Clickpad-Smartsense-M... but not found a solution.)

    Thank you very much in advance!

    I think that I recently found a solution (a partial solution at least) for this problem. The root of the problem seems to be the drivers supplied by Microsoft. The pilots, even new ones, for this clickpad are just horrible.

    What is worse, updates to these useless drivers are installed in my system without any agreement from me either. Try to avoid updates, using a Microsoft program (https://support.microsoft.com/en-us/kb/3073930 ), doesn't help - for the clickpad updates are installed in any case.

    What I did to make my clickpad works much better is the following:

    1. Download a driver directly from the author of the clickpad, Synaptics (http://www.synaptics.com/resources). For my camera, I used "Windows 10 I2C v19.0.19.1 devices". Do not install the driver again, your system will you not allow to do so due to a 'new' version of the driver 'already installed '.
    2. Disable automatic updates of your operating system, using the Protocol according to (http://www.thewindowsclub.com/turn-off-windows-update-in-windows-10). This change is not permanent, you can always activate the automatic system updates, if you wish. Of course, if you enable automatic updates, Microsoft crap drivers will be installed automatically too, deletion of all other good drivers you have installed previously.
    3. Completely uninstall the driver automatically installed for the clickpad using Device Manager (you can advance this Manager by right-clicking the Start button). Restart the computer, as required in a message box.
    4. Install the driver previously downloaded from Synaptics. In my case, I don't have to install manually, my system installed this driver 'default', without doubt, as the only available driver for clickpad on my hard drive.

    Here are the steps that I have lived to correct the problem. Now my clickpad is not as frustrating as it used to be. Make sure when you try these steps, they may not work in your particular case, because your computer might have a few important differences from my camera.
