T440/p CLUNKPAD: Pics and installation of T450 Synaptics and Alps Touchpad+buttons

#1 Post by RealBlackStuff » Thu Aug 16, 2018 2:34 pm

Got my hands an a T440p with clunkpad and -more important- FHD IPS.
That clunkpad needs to go, I want the Trackpoint buttons!

Here are some pictures of the back of a T450/T550 Synaptics and Alps Touchpad + 3 buttons.

Comparing Synaptics (left) vs. Alps (right):

Notice the dotted (Syn) vs. the smooth (Alps) backplate.

Here's a link to more and larger of these pictures: https://imgur.com/a/z5TgiBI
In the larger pictures, please note the differences in the red/blue key insides!
I hope this will help you getting the right one for YOU.


If you (for whatever reason) get an Alps, do not despair.
If you don't use the Touchpad and just want those 3 buttons for use with the Trackpoint, the Alps is more than good enough.
FYI: I described the ALPS install further down.

How to install a T450 Synaptics touchpad+buttons driver in a T440/T440p:

1. Download the latest W7/W8 Synaptics T450 driver from Lenovo, do not install yet!
==>> https://download.lenovo.com/pccbbs/mobiles/jbgc28ww.exe

2. Go to Control Panel\Programs and UNinstall your current Synaptics/Alps drivers

3. Reboot

4. Doubleclick the T450 driver you just downloaded, run it, but UNtick the option to install now.
--- It will unpack to C:\DRIVERS\Win\UNAV

5. Go to C:\DRIVERS\Win\UNAV\WinWDF\X64\SynPD.inf for 64-bit (or X86\SynPD.inf for 32-bit)

6. Edit SynPD.inf and
--- find and delete all lines with LEN0036 in it
--- find all lines with LEN200E and change LEN200E into LEN0036
--- save the file

LEN0036 is the T440 hardware ID for both clunkpad and touchpad+buttons.
LEN200E is the T450 hardware ID for the touchpad+buttons.

7. Go to C:\DRIVERS\Win\UNAV and doubleclick on Setup.exe
--- when Windows complains about unsigned stuff, click on "install anyway".

8. Reboot and enjoy!

9. Now go protect these W10 drivers against Micro$haft updates overwriting your hard work!

How to install an ALPS touchpad+buttons driver in a T440/T440p:

1. Download this (Lenovo Yoga 14) ALPS driver: https://download.lenovo.com/ibmdl/pub/p ... gh09ww.exe, do not install yet!

2. Go to Control Panel\Programs and UNinstall your current Synaptics/Alps drivers

3. Reboot

4. Doubleclick the ALPS driver you just downloaded, run it, but UNtick the option to install now.
--- It will unpack to C:\DRIVERS\Win\ALPSUNAV

5. Go to C:\DRIVERS\Win\ALPSUNAV\Vi64\Apfiltr.inf for 64-bit (or Vi32\Apfiltr.inf for 32-bit)

6. Edit Apfiltr.inf
--- there are NO lines with LEN0036 in it, so we use another (not needed) LENxxxx one
--- instead, find all lines with LEN002D and change LEN002D into LEN0036
--- save the file

LEN0036 is the T440 hardware ID for the clunkpad and touchpad+buttons.
LEN002D is an UNKNOWN TO ME hardware ID, but which is not needed here

7. Go to C:\DRIVERS\Win\ALPSUNAV and doubleclick on Setup.exe
--- when Windows complains about unsigned stuff, click on "install anyway".

8. Reboot and enjoy!

9. Now go protect these W10 drivers against Micro$haft updates overwriting your hard work!

Just wanted to say thank you for this. I purchased a T440p over the weekend and a new trackpad but didn't know I purchased an Alps. Just one note to add: I was having difficulty installing the ALPS driver on windows. I kept running into installation failure so I turned digital signing off and that allowed me to install the drivers. Not sure if that helps anyone else, but it could save some people the headache of looking google for an answer.

Cheers,
Alex

I would just like to share that I bought an Alps touchpad for my T440p, considering I could not find any Synaptics one in EU for a decent price <50£.
Under Linux(Arch Linux) it was a simple plug & play with libinput, everything works and there's no issue with two-finger scrolling nor palm rejection when writing/using the trackpoint.

All in all I'm satisfied! :D

And for people who insist they need W10, here's how you can stop Micro$haft from constantly "up/down"grading your drivers:

If you have W10 Pro or Enterprise, there's this also:

That article does not mention anything specific about drivers, but it does mention a legitimate way to disable automatic updates in Windows 10 Professional. Another way is simply placing a REG_DWORD in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU\NoAutoUpdate with the value 1.

Sadly, neither method works for the unfortunate with Windows 10 Home.

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

I did try two suggestions to keep my 3 button touchpad functionality upon restart. Now I need a fix to allow the middle button to work.

I just installed my SYN T450 touchpad and it's wonderful, however is was not without some driver troubles. I uninstalled the original driver then installed the windows 10 driver after I did the editing to the driver the install failed. This was due to driver signing I used powershell to disable driver signing (enabling driver testing mode) the other methods to disabling it requires more effort and if after a restart there is a problem you have to disable it again each time you restart, this way you just restart once and its disabled until you turn it back on despite a watermark at the bottom of your screen. Anyway after my first attempt the touchpad buttons would not work at all even though the buttons would somewhat work with drivers uninstalled. After several attempts over and over again I used the windows 8 driver offered on this thread and after editing and installing the first time it worked like a charm! After installing this driver I was able to install the windows 10 driver, after editing, and it installed and worked like a charm as well! One think I noticed is that the windows 8 driver installed drivers for a few devices whereas the windows 10 driver only touches on one device. In summation if you have windows 10 install and edit the windows 8 driver first then the windows 10 driver after editing of course. I also disabled windows 10 from installing updated for drivers in the future, I will also note I have Windows 10 Pro.

I now have the touchpad installed and IPS FHD screen, an SSD, a quad core I7 and coming soon a blacklit keyboard its not a bad machine coming from classic xx20 series thinkpads I also have a cheap X240 coming soon I am going to to this mod for as well but I hear there is double sided tape you have to fight with to hold the touch pad on, yuck!, there is no reason for that Lenovo! Anyways I may need to find some way to keep that touch pad attached when the time comes. I wish I could run windows 7 on these machines but it's support is ending soon :( Happy Thinkpading!

Just updated the above install instructions with this:

Thank you for this thread, I had no idea I bought Alps, just was wondering why none of Synaptic drivers wasn't working, lol.
Well, it was working as a generic touchpad and buttons, just no control panel and settings.

I'm interested though, is there any way to distinguish them without disassembly, looking from the top?
