Fix - T440s noisy trackpad

So I called Lenovo the other day and asked for a new track pad since mine was noisy as all heck. An entire new keyboard bezel made it to my door within a week. However, the part, dated April 2014, was still noisy. 

 

Video of the original noise: here

 

RIDICULOUS.

 

So I saw 4 screws on the back, and proceeded to disconnect it from the bezel. 

A video of the noise from the trackpad itself is here

 

MUCH QUIETER!

 

I concluded that the noise was coming from 2 sources:

 

1 - Lenovo messed up the palm rest design. The back of the trackpad sheet metal was hitting the magnesium palm rest, creating that clanking sound. 

 

2 - The trackpad design itself was undamped, creating a secondary vibration whenever pressed. 

 

FIX:

(Disclaimer: I take no responsibility if anyone follows in my foot steps. This was meant more to shame Lenovo into seeing what ONE engineer could do in ONE day, and still doing nothing despite the hundreds of complaints filed by loyal customers.)

 

1 - Add damping material between the back of trackpad and the palm rest. I had a hot glue gun handy, so I spread some rubbery glue on the backside as shown here.  I imagine thin foam tape to also work.  (note: Do not add too much material, as the pad should not rise above the bezel at any cost. Otherwise it might start damaing the LCD.)  

 

2 - Add some damping material into the spring retainer clips. Myself, I dabbed some hot glue in there. Anyone with damping grease, that would work better. Location of the clips are here

 

End result:

Video taken from same camera, same distance/settings as above here.  
Much better! I enjoy using my laptop a lot more now. 

 

Lenovo, you could have fixed this with 5 cents worth of tape and grease a year ago. 

Shame on you. Stop ruining your brand with this nonsense. 

 

PS

How about some drivers to make the virtual mouse buttons work properly in Linux? Those of us who "do" would love to scroll a webpage one day.

Re: Fix - T440s noisy trackpad

The synaptics Linux driver for the clickpad works just fine, you just have to play with the config to find area and button definitions which make you happy.

 

For example 3 buttons on top side of clickpad

Option "SoftButtonAreas" "60% 0 0 2500 40% 60% 0 2500"

Option "AreaTopEdge" "2400

 

or slide finger on right side for vertical scrolling:

Option "VertEdgeScroll" "1"

 

etc.

 

This works somewhat, but as I said already in a previous post, for "real work" beyond basic left-clicking in a stationary desktop situation the clickpad is basically unusable - this is my last Lenovo....

Re: Fix - T440s noisy trackpad

[ Edited ]

Hello, I am having the noisy issues with my T440. I am interested in trying this fix, but I'm wondering the best way to access the back of the trackpad. Is it necessary to remove the system board? I'm guessing based on what I have read you almost have to completely disassemble the laptop to get to the touchpad. Please advise if you have the opportunity.

Re: Fix - T440s noisy trackpad

I'd love to apply this fix.

 

Its the only thing left I haven't managed to fix/workaround on the T440s.

 

Its looks like you need to remove just about everything to get access.

 

More than I'm prepared to do for now. 

 

Be nice if Lenovo were prepared to offer repair for this but from past experience I think they will refuse.

 

I'll have to get used to the looks from fellow travellers and the frightened birds leaving the trees when I click the trackpad.

 

Michael
