I know that the material is ok because I downloaded the Synaptics site driver, but windows seems to lose it when I turn it off? Did anyone had this problem if so can help you.

Thank you very much

In the Menu start, open the all programs, open accessories, right-click on command prompt and select "run as Administrator".  In at the prompt, type the following command and press ENTER.

sfc/scannow                (Note that there is a space between sfc and /)

Let the entire process, then the output type and press ENTER.  Reboot the laptop.

Now reinstall the synaptics driver and when you are done, reboot the laptop again.  If during the reboot, the driver was deserted again, from windows control panel, open Device Manager and open to mice and other pointing devices, right-click on your Touchpad device and select uninstall.  Once done, reboot once again and see if Windows will find the device and install the appropriate driver.

Kind regards

  • Keyboard and touch pad stopped working on Satellite L750

    My laptop L750 keyboard and touch pad stopped working on start up. I now use a USB mouse and on-screen keyboard to do anything either. I have tried several things to fix, but nothing seems to work.

    I've updated keyboard drivers, tried related work key, updated and run antivirus software and restored to a point in time before the show. Still no luck.

    Any ideas?
    Thank you

    In any case, can you use keyboard and touchpad if you start the operating system in safe mode?
    Are you using the original pre-installed OS that you got with your laptop?

  • HP Pavilion dv7-3170ez: volume indicator not showing when the volume control

    Hello

    I own a Pavilion dv7-3170ez and when I change the volume using the slider button in the volume on top of the keyboard, the volume is adjusted accordingly, but no volume indicator appears on the display.

    Previously, when you adjust the volume, a speaker icon with a cursor jumped in the middle of the screen showing the current volume level.

    I use Windows 7 Home Premium and Windows Update and HP update shows that I have the latest version of the software. Also, I have the latest version of the BIOS installed.

    Note: the touch buttons on top (volume, speaker and enable wireless, etc) stopped working a few days after the disappearance of the sound meter, I have fixed that by connecting battery power and disconnectiong for awhile. However, the indicator is still not displayed. Don't know if this is related (I guess not).

    Thank you

    The Volume OSD is a HP MediaSmart Menu function. He has to load at startup. To do this, go to msconfig and make sure that it is enabled under the Startup tab...

  • Tecra A3X-112: Fn + F1... Touch pad to work stoppage

    Hello everyone,

    I have a Tecra A3X-112 on which Windows XP has been recently reinstalled.
    I installed Windows XP before with other different copies, but this is the first time that I've known a few misadjustments.

    My problem is that the combined with F1, F2... Fn keys stopped working, as well as Assist bottom on top of the keyboard.
    In addition, the touchpad works, but I cannot turn it off.

    I've been looking at the posts of some other users, and it seems that it is a problem to download the proper drivers from Toshiba Web page.

    My question is: what drivers for the keys?

    a. for * Fn + function keys * should I intalled * utilities * or * Hotkeys utility for display devices? * There are even some users who recommend to installed a BIOS update or a common Module driver, but I'm not sure about this. By installing the appropriate driver, are all combinations FN + function keys work, or only some of them?
    b. for * Touch Pad *, should I intalled only * Touch Pad on / off utility * or * Touch Pad Driver * is also necessary?
    c. for * help the bottoms? *

    Send me the answers, please.
    Thanks in advance for your help.

    Hello

    The features of FN keys depend on several different factors. As a first step, it is important to have installed common modules. She is named for the other Toshiba designed tools and utilities.
    Just for example: for the use of the keys FN + F2 (standby power options), you need to install modules common and tool watch.
    While the first step I recommend to install common modules again.
    When you are finished, check the functionality of the FN and post the result.

    For FN + F9, you need to install TOSHIBA Touch Pad on / off Utility. Before that, it must be installed ALPS Pointing - device Driver.
    You know, it's not easy to simply offer a solution to this. All the drivers, tools and utilities must be installed in order to good facilities. After having done that, everything should work well.

    One thing, to help buttons try with TOSHIBA controls again.

  • Replacement keyboard on Pavilion DV7-7012NR-backlit or not?

    I spilled water on my HP laptop and now the keyboard doesn't work. Everything looks very good, and it works very well when a USB keyboard is connected.

    So, I'm looking to replace the keyboard. I had a hard time finding a good game, but... HP part Surfer said that my laptop has part #681981-001 or 698782-001, "Island style paint black backlit keyboard." I found this article on ebay and elsewhere.

    BUT my original keyboard was not backlit. However, I am sure that there is a connector to the Ribbon backlit. See photo (finger pointing on this one).

    A feedback?

    This is the original factory specifications for your HP Pavilion dv7-7012nr Entertainment Notebook computer. According to the specification, this model left the factory with a "full-size island-style keyboard backlit with numeric keypad" installed.

    Of the HP Partsurfer.

    681981-001 keyboard ISK PT BL BLK U.S. (ISK = keyboard style of the island, PT = paint, BL = backlit, BLK = Black)
    698782-001 Island style paint black backlit keyboard Win8 - U.S.

    From the MSG for this model;

    681981-001 keyboard ISK PT BL BLK U.S. (ISK = keyboard style of the island, PT = paint, BL = backlit, BLK = Black)

    Part # 681981-001 is the correct keyboard, and it must match with the part number of the existing keyboard. This was the original keyboard comes with Windows 7. The 698782-001 keyboard is not listed in the MSG and probably was shipped later, when Windows 8 was introduced.

    If you have any other questions, feel free to ask.

  • HP Pavilion dv7 Bluetooth adapter no longer works

    HP Pavilion dv7.  #ABC product number WQ641UA.  My built-in bluetooth stopped working a few weeks ago. It caused an error from Outlook that seems turned off the bluetooth adapter.  Yesterday, the HP support assistant recommends an upgrade of the Bluetooth software for the wireless Broadcom 43224AG card.  Software will not load because it cannot detect the Bluetooth adapter.  I don't know how to re-enable the bluetooth feature.  It does not appear in either the BIOS or Windows Mobility Center.

    Yes... seems to be a problem with the hardware only. As a result of the manual, you can also try reinstalling the Bluetooth card once.

    You can get the Bluetooth card replaced either by calling technique supports directly or if not under warranty you can order it online at HP parts store. You can buy the piece by calling technical support also.

    HP parts store

    Enter the serial number and the number of the product in the link above and it will show you all the spare parts available for your laptop. The contact number for Bank of parts is also listed in the link. If the part is not available it also will show you all dealers allowed to the Canada.

  • HP Pavilion dv7-4020sa - fingerprint reader not detected

    Hi had this laptop new Nov 2010... HP Pavilion dv7-4020sa product number WR867EA #ABU

    warranty expired dec 2011.

    Until this afternoon everything was fine, but to turn on my laptop an hour ago, the integrated fingerprint reader is no longer detected.

    Also get an unknown usb device with problems appearing in Device Manager...

    Uninstalled the usb device and connected to the Internet via ethernet... but when I reconnect via wifi, usb device reinstall itself... ???

    Attempted to restore backups, repaired and even uninstall and reinstallation of HP Simplepass... all with no impact in this regard... I have still some no activation sensor of joy... .He tells me the fingerprint reader is not connected.

    The laptop is not fallen, bumped or mishandling somehow.

    I am running the latest version of Windows 7 Premium, with all the updates that are installed via the HP Wizard. My security suite is Kaspersky 2012... and I even disabled by attempting a restore of the system... restoration returns with a file that are not accessible, but does not tell me which file?

    I have no virus or malware on my laptop

    Help, please... It's driving me crazy...

    Thank you

    Hey Midsyork,

    Looks like you run Digital Persona SimplePass flavor.

    Two things to try, in order:

    • Hard reset
    • Remove and reinstall the validity sensor driver

    Hard Reset:

    Sometimes, all you need to do is the computer suddenly.  This method works for a variety of connection and "glued" program issues.

    • Disconnect all the external devices first.
    • Remove the AC power and battery
    • Press and hold the power button while in the minus 30 seconds
    • Reinstall the power supply for the first start only * see Note
    • Power on - connect
    • Next time you shut down the system, replace the battery.

    * Note: You can ignore the little battery aside.  If you wish, replace the battery the first time and do it with her.

    Check the software...

    If it still does not work, go ahead.

    • Control Panel > Device Manager > biometric devices > Validity Sensor > uninstall > delete
    • Reboot ...

    Validity Sensor V2.1.0.2

    • Install the validitysensorDriverinstallationpackage: it if called sp*.exe - the package will be most likely located in the downloads folder.  If you have control of "Admin", you can highlight the package and "double-click on ' to install it, otherwise just right-click, select"Run as Administrator"and install.

    This can kick things hard enough to restore the Digital Persona software.  You can hit him harder, but first...

    ======================================================================================

    What about the rest...

    You could consider running a full system scan.  I'm a demon for this.  I like a healthy file system.  It cannot solve the problem, but it will ensure that the issue is not a messed up system files, which CAN cause all sorts of unpleasant and troubled issues.  You do not really have to 'look' like a mother hen during analysis, look at the logs or 'DO' something.  He's going to take care of yourself and try to fix what it can.  The only time where that must involve it is things do not go well...  Is there a doc to help at the end to tell you what does this thing.  It is not harmful and, unless your system is broken, and it's going to die anyway, it will only make things better than they are now.

    scannow SFC

    Analyze and fix the system.  The sfc/scannow command. who will do - it will scan the operating system, looking for corrupted files and inconsistencies; He will replace or repair everything he can.  If it finds corrupted programs or libraries, it will try to correct them.

    • Start menu > all programs > Accessories > right click on guest > select ' run as administrator'
    • In the command prompt window, type (or copy / paste) sfc/scannow , and then press enter.

    (Note the space between sfc and the ' / '.)

    The sfc scan will report its findings and you can look at the results:

    • Open an command prompt (it doesn't have to be as an administrator):
    • Use the command copy to create a copy of file readable by the output:

    %windir%\logs\cbs\cbs.log copy %userprofile%\desktop\cbs.txt

    If "scannow" does not properly complete, try running:

    SFC /verifyonly

     

    Copy the results to a text file, extract the output file in Notepad and look for errors that could not fix the full scan.

    Help file for the System FIsland Checker command:

    The Windows Vista or Windows 7 System File Checker tool

  • Pavilion dv7-4180: LAN - does not connect

    Hi all

    I myself have set up in a new home and now am using a modem to the computer's LAN connection.

    I could not receive a signal when the connection of the modem to my computer, but on wi - fi systems, it works.

    Then on another computer, the LAN connection starts a blinking on the modem and there I go, connection

    through the LAN.

    The first computer that does not have a connection on the LAN-

    Q: what could cause that?

    Once again, it is very well when instead of a Wi - Fi connection and scoring in just this old LAN connection to my new residence

    does not cause it to connect to the top.

    Any advice on a particular problem is appreciated.

    Hi @AtAF,

    Thank you for your query.

    I understand that after moving into your new home, you cannot connect to your local network, is another computer.

    You are able to connect to hotspots Wi - Fi with your CV.

    When I did a search for your model of laptop, I got several results that you forgot to enter the two letters after the model number (example Pavilion dv7-4180us).

    How can I find my model number or product number?

    On this particular model that Windows 8 is not supported by HP so they do not list the drivers updated for it.

    Download or update of software and drivers for HP computers

    You did all your Windows updates?

    You use the same Ethernet cable that worked with the other computer?

    Have you ran the Windows troubleshooting tool?

    If you check device manager there is an error on the network card?

  • HP Pavilion dv7 - 2277cl "blocked, do not load"-HELP!

    HP support team,

    First of all, I really want to thank you for holding this type of support.  I have technical questions for laptop and it happens to be your guy - for Expert days how unfortunately had the chance of me!

    I have a 4 years old HP Pavilion dv7 - 2277cl, Windows 7 operating system. I had a problem for months now with my recharge battery.  Whenever I plug in the AC adapter, it is said "plugged in, not charging."  For the last two months, I was able to get away, stirring the adapter so that it can load, even if my method 'all or nothing' does more work.  I opened the Device Manager and updated the three drivers under "Stacks" (which were all updated), tried to uninstall the Microsoft ACPI Compliant Control and restart my laptop (nothing has changed). I tried to stop the laptop and tried to turn it back on with only the AC adapter is plugged (who doesn't) and even calibrated my battery - who only left until the point where I have a charge of 5%, and it has connected for more than 12 hours...

    So, somehow the battery IS loading, but only when the laptop is turned off. While the battery icon is always displayed "blocked, do not load," the battery changed miraculously since a 38-78% more than a day to load (stopcock).  Ditto for when I calibrated the battery somehow it responsible for a charge of 5% of weakness, but full of hope...

    The culprit would be the battery, the power adapter or the laptop itself? I am a broke college student so it would strain my wallet to get help in the store, I am looking for help!

    Desperate and concerned,
    Princess of pop corn

    If you turn on the laptop without the power adapter there is of course a mistake with the AC adapter. Substitute must address your situation.

  • Equium L10 - touch pad stop working (mouse)

    Hi guys,.

    really need your help. I have an Equium L10-300 and my touch pad has stopped working. A few days back, he started to freeze, but reboot solved the problem... but now it has stopped working all together. The icon that normally indicates at the bottom right of the screen disappeared. Have done the FN9 thing and tried to look at the settings...

    Help, please

    Thanks, Pete

    Hi friend

    have you already tried to remove the mouse from the Device Manager? Or reinstall the driver would also be a very good attempt to resolve this situation as a whole.

    The first step that needs to be done is to exclude a software error, then go-> http://eu.computers.toshiba-europe.com/-> support downloads & -> support-> download home page-> download drivers

    Get the driver for your mouse and reinstall. If it shouldn´t work then come here and we will see what could be the next step...

  • Pavilion dv7, tpm chip enable - not-possible or not?

    HP Pavilion dv7-4285dx laptop. This laptop has TPM or not? bought this machine about a year ago. didn't want to turn on Bitlocker and Bitlocker-to-go at the time I intend to upgrade to win 7 ultimate/Enterprise.

    When I got to the hardening of the BONES, I checked the BIOS - but could not find the option to turn on the TPM. I read many pages of documents to support, so far have not found any mention of TPM being on the MB. I'm seriously believe that it wasn't an installed feature.

    Normally the TPM is not installed in the notebook computer or consumer

    This feature is part of the PC company the of except in the two countries where it is illegal to have RPM installed on a PC.
