T450/T550 touchpad on T440/T540 mod

Hi all,
T450/T550 Thinkpads (Broadwell) have been announced and there have been a few pictures and videos on the web: Panoramic, Front

I am very curious to know if the touchpad of T450 with the physical buttons can be fitted on the T440 (Haswell).
I've measured the dimensions of the T440 touchpad+buttons from the pictures, and they seem to match exactly the clickpad size of T440.
My measurements rely on the assumption that the keyboard dimensions remain the same (I used keyboard as a reference to scale up the picture).

I know that even if touchpad/clickpad sizes are the same, cabling, form factor of underneath area etc might ruing my dream.

What do you think ?
Any brave souls out there who have tried it already ?

UPDATE A: The modification has been performed successfully

Hi all,
today I received the new touchpad with the physical buttons , and fitted it on my T440p.

Fitting the new touchpad
***************************
Before you proceed, download and have a look in the T440p maintenance guide:
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/t440p_hmm_en_sp40a25467.pdf

1. Remove bottom panel
2. Remove all screws marked with "C" + the screw under the DVD drive + the 3 screwas located in the battery area
3. Remove keyboard (slide keyboard plastic, unscrew the small keyboard bolts, disconnect the 2 connectors)
4. Use a credit card to carefully separate the top panel from the bottom and slowly remove the top panel (make sure you also disconnect the 2 ribbon cables before taking off the panel)
5. Remove the 4 short screws which mount the touchpad on the top panel, remove the old touchpad
6. Safely screw the new touchpad with the 4x short screws
7. Connect back the 2 cables of the top panel, fit the top panel back on the laptop base (you'll listen multiple click sounds)
8. Connect the keyboard cables, screw the keyboard bolts, slide down the keyboard's plastic cover
9. Put back all screws which were removed in step 2
10. Secure back the bottom panel.

****************************************
Making it work under Ubuntu Linux
***************************************
I use Ubuntu 14.04LTS with kernel 3.13.0-45-generic.
I followed the steps of " camerongray" but unfortunately things didn't work out of the box.
Here follows a short walkthrough.

The touchpad was recognized as a "PS/2 Generic Mouse"
#/> cat /proc/bus/input/devices
I: Bus=0011 Vendor=0002 Product=0001 Version=0000
N: Name="PS/2 Generic Mouse"
P: Phys=isa0060/serio1/input0
S: Sysfs=/devices/platform/i8042/serio1/input/input86
U: Uniq=
H: Handlers=mouse0 event4
B: PROP=0
B: EV=7
B: KEY=70000 0 0 0 0
B: REL=3

This is also confirmed from xinput:
#/> xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Generic Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Video Bus id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Integrated Camera id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]
↳ ThinkPad Extra Buttons id=13 [slave keyboard (3)]


This happens because my kernel's module " psmouse" does not support Alpsv7
#/> dmesg | grep -i alps
[ 1.334186] psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 0a, EC=88 b0 13

To resolve that, you either need to instal a recent kernel (e.g. 3.17), or patch+build the psmouse module with alpsv7 support:
https://github.com/he1per/psmouse-dkms-alpsv7

If you do not care about the touchpad , but only for the UltrNav + physical 3 buttons, then the guide of " camerongray" should be enough for you with a minor change:
1. Create file " /etc/X11/xorg.conf.d/90-evdev.conf " and add the following contents:
Section "InputClass"
Identifier "Touchpad/TrackPoint"
MatchProduct "PS/2 Generic Mouse"
MatchDriver "evdev"
Option "GrabDevice" "False"
Option "EmulateWheel" "1"
Option "EmulateWheelButton" "2"
Option "Emulate3Buttons" "0"
Option "XAxisMapping" "6 7"
Option "YAcisMapping" "4 5"
EndSection

2. Create file " /etc/modprobe.d/psmouse.conf", and add the following contents:
options psmouse proto=imps

3. Reboot and enjoy



===============================================
UPDATE B: Perfecting Linux configuration for a better experience
===============================================
With the previous configuration touchpad didn't work properly, and had no multitouch support.
This was because the psmouse kernel module of Ubuntu 14.04 kernel 3.13.0-45-generic did not detect properly the hardware.

The part I received from the ebay seller is an ALPSv7 hardware, and is best supported from more recent kernels (e.g. 3.18 or later).
The X11 uses the synaptics + evdev drivers.

FYI the seller answered my question and claimed it is a genuine Lenovo part (how is that possible??):

"Yes, it is New and original from the lenovo."​

I have produced a patched psmouse kernel module which makes the new (eBay) touchpad with physical buttons perfectly usable under Ubntu 14.04.

You can grab it from here, and use it at your own risk:
https://github.com/dimosped/psmouse-dkms-alpsv7

 

Even if cabling, form factor etc. fits, there is still a problem, called UEFI BIOS - it might fail at this point, even if you succed with fitting the new UltraNav into the old palmrest.

 

Very true, but I guess if the new touchpad has the same dimensions/cabling, then it's worth giving it a shot.

 

I would be very interested in this as well. One of the few things I dislike about my T440s is the lack of discrete trackpoint buttons. Although I am one of the few (apparently) who thinks the trackpad is pretty fantastic.

 

I think the trackpoint is pretty good - tracking, 2 finger scrolling, etc, with the MAJOR exception of the button design. If they took that trackpad and gave it discrete buttons for both the touchpad and trackpoint, even if it reduced the surface of it, I'd be happy.

 

Go ahead and try it out: ThinkPad T440 T440P T440S T450 T450S Touchpad Clickpad with Left and Right Keys | eBay

 

I would pay that gladly, but do we know if you can reasonably remove the touchpad from the palmrest? Don't these come out as a single unit?

 

Haha, $50!! People really are cashing in.

 

Anyone give it a shot yet to see if it works?

 

this time last year when I was looking at the t440p or e440 I would of gladly payed for one of these EASY. but for me no point now. but if you are happy with what you got already do it. infact the main advantage with the t440p is the cpu is socketed and the t450/t550 is all soldered in and im sure they are low powered cpu. where as id like to upgrade my cpu to quad if I had dual core.
if I can get a cheap t440p. then I think I wpuld do the whole buttons swap.

 

Just got a T440p of fleabay for ~500. Looks brand freaking new. I might be willing to give this a shot, but the cost has to come down from $50. I can't do that on a student's budget.

 

I knew I wasn't the only one to want to do this... If the t450 is the same size it should be possible to swap the entire top of the t440p....

once we see some reviews with measurements it should be easier to tell if it's doable..

This would take care of my only complaint with my t440p... fairly often I'll wind up moving the cursor when I'm using the trackpoint and clicking (which is all the time... )...

 

I think it should be doable. Lenovo has a habit of using the same platform (chassis, connectors, etc) for a few years in a row. The T440P was a new platform so I suspect that the T450 will be similar to that platform, if not an outright clone.

 

There is no T450p yet. The T450 is the successor to the T440, not the T440p.

Your only option is to fit in the new Trackpad into the old palmrest.

 

Hi i posted about this recently on reddit and the seller said that this will work as long as you use the t450 drivers. He also gave me the dimensions and they do match up with the t440.

 

Just noticed a new synaptics driver on lenovo's site.. in the release notes it adds support for the w541 (which has the new touchpad)....


EDIT

I upgraded to the new driver and so far, the experience with the clickpad seems better...

 

T550 / X250 driver is out now:

Hi all,
I ordered a clickpad with buttons from here:
http://www.ebay.co.uk/itm/251805759114

Waiting for it to arrive, probably within a couple of weeks.

FYI I own a T440p with dual boot (Win8.1, Ubntu 14.04 ).

I'll let you know about my experiences once I get my hands on the new touchpad.

 

This seems really exciting. I hate the touchpad but love this keyboard.

 

Would this fit on a X240? The Clickpads of T440/T450/X240 look identical to me.

Here's hoping so.

 

Guys, while browsing the Lenovo forums, I came across a thread:

A poster claims to have successfully upgraded his ThinkPad Yoga buttonless trackpad to the new trackpad, see below:

https://forums.lenovo.com/t5/ThinkP...Clickpad-with-new-TrackPad/m-p/1926801#M34208

EDIT: Scroll up on the thread to see pictures.

 

Great to see that the two parts are fully interchangeable (in terms of physical dimensions and shape).
It is also good to know that UEFI does not cause issues.

The user however initially had some problems with the physical buttons, but as it turned out, it was software/drivers related.
I am curious to see how the new trackpad will be driven by a recent Linux kernel.

For the moment, I am still waiting for the new trackpad to arrive.

 

These are step-by-step instructions how to integrate 3+2 clickpad into T440s, in Chinese though

part 1 http://www.51nb.com/viewnews-97681.html
part 2 http://www.51nb.com/viewnews-97681-page-2.html
part 3 http://www.51nb.com/viewnews-97681-page-3.html

Anyone to reproduce, huh?

 

Wow, looks like a fairly complicated process.

 

Wonder if it's any easier for a T440p.

 

Not sure about the T440P but the T540 is very easy - you only have to remove the internal battery:

Any idea where you can get these button stickers?

 

Good news!

The touchpad for my T440s arrived today and I have just finished installing it.





The hardware
============
Feels fantastic, especially the buttons which have a nice, solid feel. The touchpad itself feels pretty good as well, it is hinged at the top and clicks at the bottom (like a MacBook does) which makes it much quieter than the original one.

Installation was fairly easy although it did require the motherboard to be unscrewed and moved to the side to access a pair of the screws holding the touchpad in. The new touchpad didn't include a cable so I needed to transfer the one from my previous touchpad, thankfully this can be easily done.

How does it work?
===========
I can confirm that it works great under Linux (Arch in my case). Everything seems detected and working fine so all I need to do now is configure it to my liking. The only caveat was that I needed to put "options psmouse proto=imps" in my /etc/modprobe.d/psmouse.conf as per the instructions here.

Because this is a new piece of hardware there is limited information about it online, however some people already have the 3rd gen X1 Carbon and there is quite a bit of information about that for use under Linux. Therefore if you have issues, look up the same issue with the 3rd gen X1 Carbon.

As far as Windows goes, I have only briefly tried getting it working under but I was not yet successful, I uninstalled my current drivers but the updated ones refuse to find any Synaptics devices. I wouldn't give up hope though since I haven't tried that hard to get it working and due to it working under Linux, the hardware itself clearly works so it's just a software issue.

EDIT - Everything works under Windows with the driver here (Thanks to siya-u here)

TL;DR - Everything works perfectly under Linux, works under Windows using driver linked above.

 

camerongray: can you confirm whether this driver works under windows please? (latest t440s driver including W541):

http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/n10gx29w.exe

http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/n10gx29w.txt

 

Nicely done.

 

The touchpad only pushes down toward the buttom (like more traditional ones with integrated buttons), right? I might just have to get one of these, and use the trackpoint more - or at least use the trackpoint buttons with the trackpads. (Both of which I do when dealing with x131e carts at work.)

 

Update - I have written a short blog post here explaining roughly how I got it working: http://camerongray.me/2015/02/fitting-physical-trackpoint-buttons-to-a-lenovo-thinkpad-t440s/

I was unable to get that one working myself but I have probably missed something, in the end I installed n10gx25w which worked and I've not risked fiddling with it since

 

Yeah, it clicks down at the bottom and is hinged at the top. It can be clicked from approx half way down.

I wonder if the designers behind the clickpad got fired?

Lenovo just basically admitted that they made an awful mistake and drop the clickpad after one generation.

 

Someone on the Lenovo forums has spotted that the Lenovo FRUs are available for T550 and T450 keyboard bezels now (strangely, the T450S bezels aren't listed in the current BOM):

https://forums.lenovo.com/t5/T400-T...less-touchpad-of-a-T440s/td-p/1845449/page/3#

Looks like the T550 bezel (FRU: 00NY459) is available for $51 which, if it definitely includes the clickpad, is a bargain for a genuine item.

My concern with the Ebay item linked in this thread is that it's probably a clone and was made to work with the driver that was current at the time. I can't think of any other explanation and I'm starting to regret ordering one now..

 

The part I received from the ebay seller is an ALPSv7 hardware, and is best supported from more recent kernels (e.g. 3.18 or later).
The X11 uses the synaptics + evdev drivers.

LOL. Do you really think that somebody would bother cloning a Lenovo clickpad? How large do you think the market for these is? We're talking about Thinkpads here, not iPhones.
I'm pretty sure it's a genuine part. The seller probably has some access to the supplier who makes these for Lenovo, and they made some extra ones that they are selling on the side at an inflated price. Happens all the time.

 

Yes I do. While it does seem unlikely, how would you explain the fact the new W541 (which uses the new clickpad) compatible driver doesn't work?

A possible explanation is that they are samples containing now outdated firmware I suppose but you'd think they would still be at least recognised by the new driver.

 

I swapped out the trackpoint last night and for the life of me, cannot get the software to reveal the synaptics options. It correctly installs smbus and tp drivers but under the Mouse menu in control panel, there is no option tab to configure. I tried mulitple drivers ranging from the X230 laptop to the T450s laptop.

Any ideas?

 

I replaced my T440s touchpad with this one. Running Win8.1, can't get the ultranav option.

 

You have to uninstall your old driver and install this driver here: http://driverdl.lenovo.com.cn/think/download/driver/7448/UltraNav[n10gx25w].exe Then it will work...

 

I did. It still doesn't give me the ultranav tab in the mouse settings. The driver looks alright, but it doesn't work like a normal touchpad. No 2-finger scroll and no lenovoe-style middle button scroll.

 

Have any of the new clickpad owners here using win7/8 tried the driver on this page?:

http://support.lenovo.com/jp/ja/downloads/ds101836

Lenovo did a u-turn on the latest T440s driver (18.0.7.100) re. W541 compatibility and the english equivalent of the page currently has no content.

The potentially interesting part is the filename: n10gw15w.exe which is similar enough to the current, old working driver filename: n10gx25w.exe to look hopeful

Excuse my arguably tenuous logic but it may be worth trying..

 

I also noticed that there's an SMBus driver that works in conjunction to the main PS/2 Mouse driver. I wonder if that's whats causing the issue.

 

Guys I might be missing something here, but I guess that you have already tried to purge old drivers and install these ones:
http://support.lenovo.com/gb/en/pro...ies-laptops/thinkpad-t450s/downloads/DS102029

On a different (and maybe more risky side), if I had windows installed and the above didn't work, I would also give a shot to the followings:
Windows 7 (64 bit)
http://www.toshiba.co.uk/innovation...116&page=1&ID=94133&OSID=30&driverLanguage=42

Windows 8.1 (64 bit)
http://www.toshiba.co.uk/innovation...116&page=1&ID=94133&OSID=46&driverLanguage=42

The above 2 are drivers for Toshiba Portege Z30 which I believe have very similar ALPS hardware.

 

Didn't work on Win8.1.

 

I purchased the new trackpad on ebay and installed it on my T440s with Windows 8.1. It basically works however I have the same problem where there is no UltraNav property tab in the mouse properties (Device Manager shows the UltraNav) and no 2-finger scrolling. I have tried all the previously mentioned solutions including the new T450s driver and nothing has worked so far. The T450s driver package caused the machine to become unstable and had to be re-started. No solution yet for me. According to the seller fromChina on ebay, UltraNav[n10gx25w].exe was supposed to work but it does not.
