    Dell Vostro 3550 touchpad not working


    Hi,
    This Dell Vostro 3550 had Windows 7 Pro on it then I upgraded to Window 10 Pro then during installation the screen went blank and after searching I connected to HDMI and completed the installation then updated the BIOS and the screen was fixed.
    After the screen was fixed I then noticed the keys on the touchpad worked but the touchpad wouldn't move the cursor. After uninstalling then rebooting it seemed to work then a reboot notification popped up and after rebooting the touchpad stopped working again even after blocking driver updates in Windows Update and Policy editor.
    Thanks in advance.

    Hi, first- a basic check- boot to BIOS - does the touchpad still work there?

    If so, boot to Safe Mode- - does the touchpad still work?

    You've not stated the exact model number or given the drivers download page.
    Up to which O/S are drivers available?

    Consider downloading and using the last available touchpad driver for that laptop, then blocking updates solely for its driver by hardware id (Tutorial available). (It's not necessary to block ALL updates just to stop the touchpad driver being updated).

    Note- it goes without saying that by upgrading a laptop to an unsupported O/S means you take responsibility for any issues.

    Have you just accidentally turned it off? Some laptops have key-shorts for disabling trackpad.

    The touchpad and mouse do not work in BIOS I think because it is not that type of BIOS.
    The touchpad and mouse work in Diagnostics and in Hiren's Boot CD PE.
    The touchpad does not work in Safe Mode.
    Here's the support page.
    https://www.dell.com/support/home/en...o-3550/drivers
    I have tried the drivers there with the same results.
    I used the Windows 8 64-bit drivers.
    I don't see any other model number. It just says Dell Vostro 3550 Made in China then gives the service tag and express service code.

    And thank you for your reply.

    unusual- perhaps you mean you can only navigate using keyboard

    The touchpad and mouse work in Diagnostics
    - could you explain what you mean by 'Diagnostics'?

    The touchpad and mouse work in Diagnostics and in Hiren's Boot CD PE.
    - it might be interesting to find which driver is used by the latter.

    Potentially if it is a driver issue, you could export that and use it.

    Yes I can only navigate the BIOS using the keyboard

    The built-in diagnostics that can be accessed through the boot menu.

    - it might be interesting to find which driver is used by the latter.
    After uninstalling Dell Touchpad then setting the hardware ID into the policy and restarting the touchpad worked.
    It now shows in Device Manager as PS/2 Compatible mouse by Microsoft with a date of 6/21/2006 and driver version 10.0.19041.1.

    Potentially if it is a driver issue, you could export that and use it.
    I'll see if I can save just that one driver using Double Driver.

    - - - Updated - - -

    I was able to backup that one driver using Double Driver.
    Thanks for your help.
