my touch pad stopped working 3 days ago. For reasons I had to remove the battery and after I turned the laptop on, there was no cursor. I tried Fn+F5, but nothing happened. I reinstalled the driver couple of times, I made updates, I did a clean boot and other recommendations from the internet. I can't find any touch pad options. When I go to the additional mouse options it says "Unable to connect to the Synaptics Pointing Device Driver" and I should uninstall it, but I did it like 20x. Seems like the laptop doesn't recognize the touch pad. I don't think that there's a physical damage.
Came across this in an article:-
type msconfig from search
On the startup tab open taskmanager
right click the synaptics touchpad
and under compatibility tab check run this program as administrator then restart
Have you tried rolling back the driver or your laptop to a previous date before the problem occurred?
Does that include returning your PC to an earlier time before the problem happened?
Which OS are you using and what make is the laptop?
Have you tried doing another hard reset, taking the battery out, removing the AC adaptor, pressing and holding the power-on button for 20 seconds, then using the fn + key to toggle the touchpad on/off?
When you reinstalled the drivers did you go to the manufacturer's website?
Have you tried all of the other suggestions? YOu have not said which OS you are using.
Have you tried this?
Go to Start -> Control Panel -> System -> Hardware tab -> Click "Device Manager" -> Find the item called Mice and pointing devices and click the + sign. If synaptics is listed right click and select Uninstall. After that completes go to the top of the Device Manager and select Action -> Scan for hardware changes...it should find the device and attempt to reinstall it and the driver.
