finally, I found the way to use T450 driver to fit my T440P on Win10….
Pre-requirement:
1. uninstall any Synaptics driver.
2. download the tool from the following website that can prevent the driver update from windows update.
[URL]https://support.microsoft.com/en-us/kb/3073930[/URL]
3. Download the latest T450 driver from lenovo web site [jbg206ww.exe]
Setup the latest T450 driver on T440P:
1. Run jbg206ww.exe and only extract files without installation.
2. Edit x64/SynPD.inf under the folder to which the driver is extracted.
3. you will find three line as follows.
Be aware that “LEN0036” is the T440P Hardware ID.
please check your hardware ID from device manager in control pannel.
===================================================
%SMB.IBMDeviceDesc% = LENOVO_GROUP36_InterTouch_Inst,ACPI\LEN0036
%SMB.IBMDeviceDesc% = LENOVO_GROUP36_InterTouch_Win8_Inst,ACPI\LEN0036
%SMB.IBMDeviceDesc% = LENOVO_GROUP36_InterTouch_Win8_Inst,ACPI\LEN0036
======================================================
4. delete the three line.
5. find the three line below.
%SMB.IBMDeviceDesc% = LENOVO_GROUP41_InterTouch_Inst,ACPI\LEN200E
%SMB.IBMDeviceDesc% = LENOVO_GROUP41_InterTouch_Win8_Inst,ACPI\LEN200E
%SMB.IBMDeviceDesc% = LENOVO_GROUP41_InterTouch_Win8_Inst,ACPI\LEN200E
6. replace “LEN200E” into “LEN0036” for the three line
LEN200E is T450 hardware ID.
7. save the change and close the SynPD.inf file
8.Restart by command in cmd: shutdown /r /o /f /t 0 (other method: Hold shift down and click restart)
On the boot manu
Select Troubleshoot > Advanced Options > Startup Settings > Restart
In restart, select option 7. (you must select 7 to bypass digital signature ,otherwise the driver installation will be failed. )
9. Go to the folder to which the driver is extracted.
Run setup.exe normally.
During the installation, the warming message will pop-up that metioned without digital signature.
please agree it to complete the installation.
now the latest T450 driver will be installed ,but the driver did not have digital signature just because SynPD.inf was modified…….who cares….
