Thinkpad Yoga Touchpad Driver Issue

Hello, my Thinkpad Yoga touchpad has decided to entirely stop working. Here's what happened:

 

A couple of days ago, I re-start my computer. On boot, I get a beep error saying something along the lines of "device not found" and another saying "device number not correct." Sorry if I don't remember the details, I didn't think it would be a big issue at the time. It told me to press escape to continue and enter to enter setup. I click continue.

 

It boot up, yet my touchpad was entirely non-functional. When looking at the device manager part of Lenovo Solution Center, I see the following:

 

Drivers                                                            Status

Unknown Device                                            Not Installed

ThinkPad UltraNav Pointing Device               Disabled

 

When I go into device manager, I see something different, however. I click "show hidden devices" and under "Mouse and other pointing devices" there is "ThinkPad UltraNav Pointing Device".

 

Here's what I see when I view the properties of that device:

 

Device Type: Mice and other pointing devices.

Manufacturer: Lenovo

Location: Plugged into PS/2 mouse port.

Device Status: The device is not present, is not working properly, or does not have all its drivers installed. (Code 24)

 

When I connect a mouse to a USB port, then that mouse works fine. Its just the touchpad which is broken. I tried re-installing the mouse driver, but nothing ever seems to change. I've also tried refreshign the machine, also no change.

 

If anybody could help that'd be greatly appreciated.

Re: Thinkpad Yoga Touchpad Driver Issue

I managed to get the errors to come up again (somehow). Here's what they are:

 

0187: EAIA data access error

2200: Machine Type and Serial Number are invalid.

 

Here is the Machine Type Model in bios: ???? (I'm not joking it literally lists ???? next to Machine Type Model)

System Board Serial Number: 40C1KS30S0?

 

What's weird is, I searched both of the errors on google, and when they came up, on ALL of the results, the person complaining of those errors couldn't get their computer to boot. On mine, it boots fine, just a specific device (touchpad) isn't working. Also, I went into the "Keyboard/Mouse" section of my Bios, and the only thing it showed was switching the control & fn keys. Nothing else. Possible bios error?

Re: Thinkpad Yoga Touchpad Driver Issue

I had very similar issues with the latest driver; device would disconnect, freeze, interfere with keyboard, display as "disabled" in device manager.

 

I simply just removed the synaptics driver and use the touchpad as a standard PS/2 device. Vastly improved stability but however you lose two finger scroll and gestures. 

 

I also am looking for a better solution.

 

(I also disabled the active protection and transition software from lenovo - much better keyboard/touchpad performance and stability).

How would I go about doing that? Every time I try to do it, it still displays an exclamation mark and defaults back to some kind of synaptics device.

Re: Thinkpad Yoga Touchpad Driver Issue

Swwils, when you disable the gesture support and just use the touchpad as a ps/2 device, are you able to get middle-click functionality from the top center of the pad?  Or are you left with just lef/right click? 
 
I was surprised to see how much cpu the pad uses.

Re: Thinkpad Yoga Touchpad Driver Issue

Pressing the middle click acts as sort of a "sticky" key to enable/disable scrolling; so under the PS/2 device it is still a sperate button.

 

Merry christmas!

Re: Thinkpad Yoga Touchpad Driver Issue

Hello,

 

I tried changing the driver to a PS/2 Compatible Mouse, still says "This device is not present, is not working properly, or does not have all its drivers installed. (Code 24)". Any other ideas for possible fix?
