firstly get the generic driver from synaptics
then go to device manager and go to the ps2 mouse and uninstall previous driver
1) Extract the files to another folder
2) Open the folder with extracted files copy the path of the x64 drivers
3) Go to Control PanelDevice ManagerMice and other pointing devices
4) Right click mice and other pointing devices, select Update Driver
browse the computer
then select HAVE DISK VERY IMPORTANT
5) Add the x64 drivers path
6) Select Dell Touchpad or synaptics
7) Install drivers
8) Restart
-------------------------------------------------------------------
but it probably wont work so
so see here forum.notebookreview.com/.../page-2
and here answers.microsoft.com/.../ca01bc04-0db7-4241-bff9-192cfb5af012;auth=1
So what you need to do is:
1. Disable PTP drivers
2. Install generic drivers (force way)
1. Disabling PTP drivers:
Go to device manager and locate "Human interface devices" node (node means the little arrow which expands). Locate "HID-compliant touch pad" item and disable it. (To make sure, you may open device properties and on Details tab, in the dropdown go to Hardware IDs property will have this line HID_DEVICE_UP:000D_U:0005 - this is how TPT reports itself). (with mine i had a 4 instead of a 5
Now, in the same node, disable "I2C HID Device" item.
Done. PTP is dead.
the mouse wont work so use touchscreen
(i cant remember if i did a reboot here or not)
2. Installing generic Synaptics drivers:
Download generic Synaptics driver here: synaptics.com/.../drivers.php
In device manager, go to "Mice and other pointing devices" node and locate your touchpad disguised as "PS/2 mouse". Select "Update driver" from context menu and make it hard way: "Browse my PC" - "Let me pick it myself" - "Have disk" - point to folder where you have unpacked downloaded driver into (x64 subfolder, to be precise). Windows will say that driver is not compatible. That's a lie. Press Yes. Reboot. You're on generic driver now. Scroll and 2/3/4-finger gestures are at your disposal.
During phase #2 Windows may complain about missing digital signature at driver's package (Synaptics' fault). There are 2 ways to circumvent it:
1. Disable driver signature enforcement (just google this whole phrase). This is easy but potentially creates security risk as from now any unsigned driver can be installed to the system.
2. Sign it with a valid certificate if you have one (also requires installed WDK).
I did mine by signing .inf file with my company's certificate, but I'm not sure if I can redistribute it.
From my experience, precision of generic driver is inferior to PTP, but it's free of PTP bugs and offers all extended features Synaptics has to offer. Or maybe it just requires tweaking (it has so many parameters).

now for chirascroll do this
Requires use of regedit
Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\03TabScroll\ 4OneFEdgeScrollChiralInfoText\ and inside the other window there will be a key called visibility
also do this for Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPCpl\Controls\03TabScroll\ 4OneFEdgeScrollChiralCheckBox\ and inside the other window there will be a key called visibility
Find the items and
Change the Visibility key of both from 4 to 0
Open the Synaptics control panel, go to scroll tab, it will have appeared
----------------------------------------------------------------------------------------------------
finally mess around with
If you want to tweak the settings for the three mouse-speed settings (MouseSpeed, MouseThreshold1, and MouseThreshold2), launch the registry editor and go to HKEY_CURRENT_USER\Control Panel\Mouse\.
Along with a few other settings, you'll see the three mouse-speed values in the right panel. Mouse-Speed is a multiplier that is set from 0 (always run at the basic speed) to 2 (multiply the calculated speed by 4). MouseThreshold1 indicates the number of pixels you must move the mouse between interrupts to automatically double the basic speed (unless MouseSpeed is not set to 0). By default, MouseThreshold1 ranges from 0 (do not introduce speed-doubling) to 10 pixels, but you can set its value to higher than 10 if you like. Setting the value closer to 1 makes Windows introduce speed-doubling sooner, which causes your pointer to pick up speed.
The last of the three pointer values, MouseThreshold2, behaves like MouseThreshold1 except that it causes Windows to again double the mouse's speed.
but i am not sure if it makes a difference
i have tested it and i dont think it makes any difference
-----------------------------------------------------------------------------------------
BUT here is what i did and it does work!
i downloaded a program called regshot which is free and it compares the registry before you make a change and after you make a change (there are probably other programs as well but i found this the simplest of the lot)
i then changed the mouse speed in the synaptics driver. i then used the reg compare and it directed me to a folder in the registry hkey current usere/software/synaptics/syntp/touchpadps2tm3014/pointermotionspeed
edit the speed to a higher number such as 300 instead of 190
i could not find this in the default windows program called regedit but i downloaded a program called registrar registry manager which shows a lot more than regedit and you can edit it there
you can use this method to find the appropriate registry key to edit for whatever you wish
i am no computer expert and accept no responsibility for these methods but hope you have enjoyed hacking and credit to the forums which got me this far
regards
