Problème de la "molette" du touchpad

In the installation CD of the system, or online, on the official manufacturer's website, or on other well-known sites where you can find all the drivers... ;)

Because the manuals don't say everything...

Here I am after two hours of research and struggle, it's working again by downloading the latest driver, good luck to you, here is the link http://www.station-drivers.com/page/Synaptics.htm

I had the same problem on an HP laptop, I restarted it and it worked again.

Good luck to everyone who has this issue!

alicemcht is recovering the system, that solves the problem. ^^

Same problem, the scroll wheel just stopped working overnight... Same computer.

Hi, I also have the same problem, the touchpad scroll wheel isn’t working anymore, I think it’s after the Windows update I did (Windows update), well I'm not sure, I'm not a computer whiz ^^, if someone could find a solution that would be great :)
(for info, I have a HP DV7 1199 ef)

To all: reinstall the original driver for the touchpad.

And avoid posting things like "I have the same problem," as it takes the forum out of the 'unanswered' list, decreasing the chances of getting a response... solution! ;)

Hello, I have a problem that's a bit different from this one; actually, it's my touchpad. I tried yesterday and managed to get there, but it told me to uninstall PS/2 because it was not found or something like that. I clicked yes, and since then the Dell Touchpad tab has disappeared. I have a system and driver CD with my computer that I tried to use, but it doesn't execute; it just opens the folders inside. So, does anyone have a solution, please?

Thank you.

Hello, I have read all the solutions you provide but none of them work for me. I am on Windows 8 Pro with a Samsung. No matter how much I go into all possible settings regarding the touchpad, the mouse, etc., nothing resolves my issue. The scroll wheel on the touchpad works with two fingers on the touchpad, and for some time now, it has stopped working. I once managed to fix this issue by pretending to modify the touchpad settings, as everything was enabled. Unfortunately, this time, it didn't work... Could you help me?

Hello everyone,

Conf MSI GT72 Q, uh, brand new of the day.
What a hassle, yes ^^ Windows update most certainly removed the two-finger actions.
ON/OFF touchpad: fn + f3
You won’t find anything in Windows mouse settings.
It’s found in a separate driver, for me, located in the hidden toolbar next to the update flag (bottom left of the desktop).
Utility called “SYNAPTIC TOUCH PAD” or “Synaptic pointing device.”
A window opens “mouse properties” > click on “device settings” > “settings” > expand the “Scrolling” option > “two-finger scrolling”
wow, the Alibaba cave for fingers that smell is here!

And be careful where you put your fingers! lol

The issue on an Asus G751 is different in part > drivers to be reloaded from Asus by digging well, and beware of a secondary Windows 8.1 update that can screw everything up :) and fingers up your nose.

For HP, there's the touchpad lock in the indentation, otherwise mouse settings or ergonomics.

Be careful with the ergonomics functions especially for the numeric keypad on W7 and W8.1!!!

A little aside :)
(
Don’t forget to thank artisans and small businesses by giving them work instead of going to big retailers where it’s often more expensive and surely risky all around with a bunch of incompetencies that exceed those of the RSI (organized gang of legal racketeers that kill artisan shopkeepers with illegal methods).
But why don’t we learn French law in school? When no one is supposed to ignore it. To create uncultured privileged people and fearful sheep!!!

and where do we find the driver?

Hi, you need to go to the control panel, then in "mouse" go to the trackpad tab and reactivate vertical scrolling.
