I was using my Toshiba Satellite and it froze up. I turned it off and then back on and my mouse pad stopped working. My cursur will move and highlight an icon but will not follow the command when clicked. I tried the function key and f9 and nothing.
Just press simultaneously Fn+F5 or Ctrl+F5 (or Fn + F9 or Ctrl+F9) and that should do it!
Edit:: Try swiping on the touchpad from right to left. This will bring up the little sidebar on the right of the screen and the date on the lower left in Windows 8. Then your touchpad should work as normal. F5 is the button to lock the touchpad. If your problem goes beyond that and is stuck in scroll mode like mine was, try the swipe from right to left and see if that normalizes things. I discovered this trick by accident when trying to wipe dust off my touchpad. ;)
There is an icon that is called "Synaptics Pointing Device" at the bottom of the laptop it looks like a computer screen
Click on it and it will have a command "Tap to Click."
That will get the keys working again.
Just fixed the same problem on my Toshiba Laptop. I think I may have clicked it in error .
f5 is for enabling and disabling touch pad on toshiba satellite; however mine would switch back from able to move the pointer to scrolling from object to object while touchpad is enabled. It is annoying. Does that make sense?
None of these options fix my problem. I know that the f5 key disables and enables it but I have not accidentally hit the key. I have a new laptop have only had it 12 days and only used it 4 times its a brand new laptop not reconditioned, or have ever been used in any way and all of a sudden the cursor will not respond to my touch on the mouse pad. I have had several problems with laptops in the past where its been brand new and something will start going wrong with it the moment I touch them. If any one else has any other possibility as to why my mouse is malfunctioning please let me know.
Please try these generic troubleshooting steps and see if this fixes the issue:
1. Some computers have a touchpad disable and enable hot key, refer to User's Manual of your laptop to see if your computer has this hot key and how to use it. (When your computer does not have the hot key or the hot key did not correct the issue proceed to the next step.)
2. Turn off the computer (when the touchpad does not respond hold the power button down for up to 15 seconds to turn off the computer).
3. Unplug everything except the power cord (AC Adapter).
4. Power on the computer and retest the touchpad. If the touchpad still does not work correctly proceed to the next step.
5. Make sure the latest driver for the touchpad is installed (you may need to use a external USB or Bluetooth mouse to install the drivers).
