FN + F9 should enable / disable the touchpad goto control panel - mouse - and see if you can change disable/enable touch pad from there Otherwise post back what windows version you have
Touchpads
you can enable and disable the touchpads Touchpad: - to enable or disable a touch pad/pointing device from the Start Menu > control panel > Change to classic view - {on left hand menu} click on the mouse icon Mouse Properties dialog box, click "Device Settings tab" select the device click to Enable or Disable OR You may need to enable in the bios/setup menu - as the PC boots - you should get a message on how to get into the bios/setup - usually using F2 or DEL Key or F10 see if touch pad needs to be enabled there OR one of the F keys may disable/enable - depends on the model of the Laptop - toshiba sometime use FN+F9 key

----- control panel - mouse - see if touch pad disabled there ----- have a look in the bios/setup and see if the touch pad is disabled there, as the PC boots - you should see which key to use to enter the bios/setup F2, F10, DEL KEY are often used ----- On some machines a combination of FN and F key can disable/enable the touch pad - F7 or F9 ----- If you point the mouse to the top of the screen you may get a menu dropdown, which will also tell which key to use to disable/enable the touchpad ----- control panel>system>{vista}lefthand side device manger or {XP}hardware>Device Manager>Mouse and other pointing devices>Touchpad>highlight touchpad and right click, Properties, may be an option here to Disable/enable,

Fn+F9 is the hot key for enabling or disabling the touchpad

maybe your driver is not working well http://www.rudytarigan.com/laptop/toshiba-satellite-l310-drivers.htm go to this site you can find drivers of toshiba there. reinstall some of your not compatible drivers.

Try going to Toshiba's support page and re-install the driver for the touchpad. If this does not work. You may need to replace the touchpad itself.

Hold down the [Fn] key and then press the [F9] Key to toggle touchpad on and off

On my Toshiba Satellite 1135-S155 Fn key is in the middle of Control [Ctrl] and Alt [Alt]

Disabling touchpad for toshiba laptop is easy. Press FN and F9 simultaneously. Touchpad will stop working.

My Toshiba Satellite A45 S120 keyboard has a problem, some of the keys are not working. When you type it does noting. Sometimes when you start the computer, it continuously types the letter eeeeeeee. You can hit some keys randomly and this will stop, but if you start a program (eg. ms word) the same thing happens.

Ok so here goes.... I had the same problem:

Go to the 'start' button and then hit the 'control panel' option, then click 'mouse' then go to 'Device Settings' and then to the 'settings'. When you get to this screen it shows a list on lthe left hand side choose the 'tapping' option and then ok.

Hope it works for you...it did for me.
