The left mouse button has suddenly stopped working on my touchpad. I tried to restart including taking the battery out but this didn't help.

I tried to uninstall the driver (called Synaptics Ps/2 touchpad port on my control panel). It then asked me if I wanted to uninstall the software. I clicked yes.

After this, the driver now changed to being called just PS/2 touchpad port but there is still an option to uninstall available.

I tried to uninstall again but nothing happens. I tired to download new driver software for Toshiba touchpad from the website, but it is failing to download.

I am able to use an external mouse normally but would really like to get my touchpad working normally again.

Can someone please advise on what might be causing this problem and how to fix it?

Thanks.
