Toshiba Satellite C55A Synaptic touch pad not working

[malti]

Toshiba C55A Laptop, with genuine OEM windows 8.1 4gb ram with Celeron dual core processor.The Synaptic V7 touch pad stopped working.

It stopped working when :

Windows update failed
Did a system restore
Re-installed updates
Touch pad still not working
Microsoft tech suggested windows re-instal due corrupt files.
Re-installed windows, problem persists

At the Device Manager:

Uninstalled the touch pad driver
Re-installed various versions of the driver, including the latest one from windows update
Still the problem persists
I am working with a usb mouse 1
HELP !

The timing sounds like a coincidence. You seem to have played around with the driver as much as you can. I think you have a touchpad that just failed on you (that or the cable for it is loose or faulty).

But just in case: Check for a hotkey toggle on the keyboard. Some laptops have hotkeys that will enable/disable the touchpad. Make sure that's not all it is.

The problem was solved long time ago, it was the EFI bios

Paul, I am having a similar problem. Can you describe what the "EFI bios" issue was and how you resolved it? Thank you.

Randy - on my different version of Satellite - the F9 key toggles the touchpad on & off - give that a try!
