Just a few minutes ago, my touchpad left click and tapping stopped working (with no mouse plugged in). I was just doing normal Excel work on my computer when it happened. The right click still works, and when I plug in a mouse, left click works with the mouse (but still not when I use my touchpad with the mouse plugged in). I tried restarting my computer, but that didn't help. Also, when I change my touchpad settings to be left-handed, the left button still doesn't work, but the touchpad tapping starts working again.
When I go to Device Manager, it says that the touchpad I have is the "Synaptics PS/2 Port." I'm running Windows 7. The laptop is a Toshiba Satellite C650.
Any advice you have that can help me fix this would be greatly appreciated. I'm curious if you think this is a hardware or a software issue. I would guess software since both the left click and the tapping stopped working at the same time (but scrolling still works). Let me know if I need to provide any other information.
