update the touchpad does not appear

Hello

I am currently running windows 7 on a dell vostro laptop 3550.  In order to disable my touchpad, I was told to update my mouse for Alps Touchpad Alp driver: www.dell.com/.../DriverFileFormats .  I installed and restarted my computer, but the new driver does not appear in my control panel.  What should I do?  Please let me know how to view the new driver, or how to turn off the touchpad.
Thank you

Hello

This looks like some system files are corrupt, and that's why the computer is not able to detect the correct drivers correctly. So, I recommend you to please follow the steps that might help you solve the problem below.

Method 1: Create user account

Try to create a new user account and check if you have the same problem.
To create a user account
1. to open user accounts, click the Start button, select Control Panel, click user accounts and parental control, and then click user accounts.
2. click on manage another account. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
3. click on create a new account.
4. type the name you want to assign to the user account, click an account type, and then click on create an account.

For more information follow the link below:
http://Windows.Microsoft.com/en-us/Windows7/create-a-user-account

If it works in the new user account, the user account may be corrupted.

To fix the damaged user profile, you can check the link below:
http://Windows.Microsoft.com/en-us/Windows-Vista/fix-a-corrupted-user-profile

Method 2: Scan (Scan SFC) System File Checker

(a) click Start
(b) select run and type CMD
(c) type sfc / Scannow

It contributes to the digitization of all immediately protected system files and it allows to know the system files corrupted on your computer.

Also, take a look at this article.

  • Satellite C850D-11 q - keyboard and the Touchpad does not

    The laptop is a little more than a year and worked ok until recently.

    Symptoms were the keyboard and the touchpad does not not on page 8 of windows logon. Pressing power to put the laptop into sleep and pressing still often got their work.

    He progressed to the keyboard and the touchpad works do not randomly points while the use of the laptop.

    Finally cleared the HARD drive and restored windows 8 alone, the laptop still BSOD quite frequently - refuses to install the updates required for 8.1 and the keyboard and mouse often do not work even in BIOS Setup page. I reinstalled the RAM and HARD drive.

    Short of ideas, the keyboard and the touchpad work and so I guess that their connections are correct - but often they just stop.

    Any ideas appreciated?

    Thank you

    Hello

    > Finally cleared the HARD drive and restored windows 8 only
    I hope that you created before Toshiba recovery disks you have formatted the system.
    Did you?

    The recovery disks will allow you to reset the laptop to factory settings; on the same State as at the first day of the purchase.

    > First symptoms were the keyboard and the touchpad does not not on page 8 of windows logon. Pressing power to put the laptop into sleep and pressing still often got their work.
    Well, usually the keyboard problems are not problems system or software as the keyboard driver is part of the system and an additional installation of some drivers is not really essential and necessary.
    That is why in most of the cases the keyboard problems could be the causes of physical problems.

    However, after using the recovery disc and the parameters of the laptop back to factory State, both parties (keyboard and touchpad) should work perfectly.

    > the BSOD laptop still quite frequently - refuses to install the updates required for 8.1
    BSOD doesn't look very good. As mentioned above; parameters of the laptop back to factory settings should solve all the problems in the system. In the case where the BSOD appears even if the power has been turned back to factory State, a hardware problem could be the reason for this.

    I had also some problems with the update 8.1 Win. The system to win 8 could not find the Win 8.1.
    But the reason for this was simply. I had to install all updates to Win 8 and had to update the State system before trying to update to the next level following 8.1 Win

    So, what can I say: I will try to put the laptop initial configuration using the recovery disk.
    Then I would try to get automatic updates (a few reboots were essential too). After that, I would check the functionality of the keyboard and the touchpad. In the case where them parts would not work, I would contact the service to check if the two pieces.

  • FN + F3 disable the Touchpad does not work. Dell XPS L702X

    Hello, I am new to this forum.

    The function FN + F3 that disable the Touchpad does not work, my laptop Dell XPS 17 (L702X)

    I googled my problem and the only thing I found was this: http://en.community.dell.com/support-forums/laptop/f/3518/t/19454265.aspx

    I think that my problems with the touchpad started when I plugged a mouse into the USB port. It didn't work (it worked well before), and in material-sound-mouse control panel, the system asked me to uninstall a driver or other. I do not remember, but later the mouse worked.

    After this weird thing with the mouse, I noticed that the touchpad was malfunctioning. While I write, the cursor moves without touching the touchpad, it is annoying because it makes me write bad because he is moving in the middle of writing, as I write so it's a mess.

    The second oddity, the Fn + F3 does not disable the touchpad, the orange light come on (the led on the top of the touchpad), but the cursor can be moved in any case, with or without a connected mouse.

    I checked for driver updates, perform an audit of the system, checked for viruses, spywares and I don't know what I could do. I don't know if the problem with the mouse had nothing to do with the function Fn + F3 problem.

    I have not formatted or re installed windows 7, never.

    In Device Manager I have this:

    -mouse and other pointing devices:-Compatible PS/2 mouse

    Help, please. Thank you.

  • Satellite X 200-219 - the touchpad does not work as it should

    Hi all

    I recently bought a 2nd hand Toshiba Satellite x 200-219. Had some problems with it that I have overcome now, except one... The touchpad does not work as it should. I think that the cable has been damaged at some point.

    So I'm wondering if I should use the same ribbon cable to connect the keyboard to the motherboard or can I get one of a different model of PC Toshiba laptop?

    I tried searching on the net for advice but have resulted in nothing so thought I would try the forums.

    Any help you can give will be greatly appreciated.

    Thanks in advance,

    Lee

    I think you can use the items to the satellite X 205 series since this seems to be the same series as X 200:
    Found some related parts the touchpad:
    Satellite X 205 / X 200 touchpad Board with cable: reference number: K000047950
    Satellite part number for the TOUCH PAD FFC X 205 / X 200: K000047980

    But why you n t come into contact with a Toshiba authorized service provider in your country and order the part necessary and compatible?

    If you encounter this flicker, then the next troubleshooting step is to restore from a backup. If the behavior persists after the restore, then the last step is the factory restore. If after the factory restore and adding no additional content, you see always this problem, then you must make an appointment at the Genius Bar to the nearest Apple store or service provider authorized Apple to have the material examined. If the behavior goes after the factory restore, then sync again your content manually, without using the backup. It seems to me it's corrupted content in the backup.

    I have laptop (hp probook 4520 s), the touchpad does not work. How can I turn it back on it?

    This is a question which would probably respond by HP support, because it isn't really a Windows problem.

    Are you sure that the touchpad is not just turned off? Many laptops have switches, power switch, so you can rest your palm while typing one is not worry by pressing the key.

    Sometimes, there is a button above the key, a key on the Ko, or some have a stain on the pavement you waiting/tap/double tap/etc. to toggle the pad.

    If not, you could try to go on the site of HP and DOWNLOAD/reinstall assistance the SW for the touch pad.
