ALPs Touchpad

polaris6 · 10-08-2009, 08:48 PM

I have a Dell Latitude C840 that has a stick and touch pad, neither of which seem to work. I connect a USB mouse to the USB port to move the cursor. I can't remember when it stopped working, but I need it to work now and I can't get it to 'budge'. I also have a PS/2 mouse which also works.

I have installed the appropriate driver; my Device Manager tells me that it the Alps touchpad is installed and working properly but it won't budge when I try to move it (neither does the stick).

All my other Dell laptops have touchpads that work with the Alps driver.

Any help/direction.

Thanks

Most laptops (Dell included), have an application package installed which controls laptop specific features (such as touch pad and stick). Ensure it is enabled.

I have that software/drivers installed. The Device Manager tells me it is working properly, yet, nothing moves when I slide my finger over the pad or move the stick.

I am at a loss for what I can do about this. but thanks for your effort.

Have you verified the pad is active in the software? There's more to it than just installing the software. The software has options to enable/disable the various hardware, as well as configuration options for how it is used.

Sorry about the basic questions, but how do I verify that the pad is active?

I have viewed the software options, but I have not found anything that indicates an active/inactive pad. All I have done was to verify that the Device Manager recognizes that the device has a driver that works.

Give me a little push in the right direction.

thanks again.

Looks like they've changed things a bit. According to the user manual, the touch pad and stick are configured using the Mouse Properties.

The 'Mouse Properties' show the Alps touchpad being installed; the properties of the 'pad' gives me the same display I get when I go to the Device Manager, namely that the device is working properly. If I update the driver, I am 'told' that what I have installed is better than anything else they can find.

What has to be done to 'configure/activate the pad?

According to the user manual for your laptop, it simply states that it can be enabled/disabled and configured to your preferences via the Mouse Properties.

All of the Dell laptops that I've used, have a separate Dell application for also controlling these functions. It shows up under programs and usually has an icon in the task bar.

Try downloading the latest software/drivers from Dell. Then uninstall your current "ALPS" driver, and install the new drivers.

polaris6 · 10-17-2009, 10:29 AM

I am doing that as we 'speak'. I will be back to you in a few minutes.

I also just found this: http://support.dell.com/support/topi...doclang=en&cs=

My BIOS is pointing to 'Touch Pad/PS-2 Mouse. I have installed the softtware 'fresh'. I have the ALPS touchpad icon displayed at the bottom right of the screen (task bar).

My Mouse Properties shows that the ALPS mouse is there, but I have no 'configure option that I didn't have with the mouse.

I do have a USB mouse installed and working; that is what I have to use to get things moving on the screen.

Dogg · 10-17-2009, 10:47 AM

Does it work if you disconnect the mouse?

polaris6 · 10-17-2009, 10:49 AM

no...

Dogg · 10-17-2009, 10:52 AM

I'm out of ideas. If I had to guess, I'd say it likely needs to be replaced.

Maybe someone else will have a better idea, and this likely needs to be moved to the laptop forum.

polaris6 · 10-17-2009, 10:54 AM

Could/would you do that for me?

pettyfog · 11-15-2009, 09:42 PM

I also have a Lat C840 and the touchpad started acting up about three weeks ago, right after a Win {2000 Pro} Update

polaris6 · 11-15-2009, 10:12 PM

I still have not solved this problem. It drives me crazy since all my othere computers have a working touchpad and this one does not.
