Synaptics touchpad not working

Press the "Fn" and "F9" keys simultaneously.
Test your touchpad. If it works, it was simply disabled. Press the same key combination any time you want to toggle your touchpad on or off.
Plug an external mouse into a USB port on your laptop if the key combination didn't work. Follow onscreen prompts to install the mouse driver--if necessary. You can also move the cursor using the "Tab" key and the arrow keys, as well as click by pressing "Enter" until the mouse is operational.
Click the link in the Resources section if you are using a Toshiba Satellite with Windows Vista. Follow the onscreen prompts to download and re-install the driver.
Open a web browser and navigate to Synaptics.com if you have a different Toshiba model or operating system. Synaptics brand touchpads are used in all Toshiba laptops, and this site provides a generic driver.Hover your mouse over "Support" on the top menu, then select "Drivers" from the drop-down menu.
Select your operating system from the list provided and download the generic driver
Follow the onscreen prompts to install your new driver, and then test the touchpad again. If it still does not work, take your laptop to a licensed repair technician.

If battery works and ac adapter has problems that means electrolytic capacitors maybe dried up(not supplying the current needed to run the laptop) and has to be cured by using the laptop more often.

Check to see the make of your touchpad (in most cases it would be a synaptics one.) If so, go to http://www.synaptics.com/support/drivers and download the corresponding driver according to your operating system.
NOTE
I'm assuming you already went through the basic steps such as checking if there's a dedicated touchpad button which might be turned off, checking if from control panel\mouse the device is not disabled, etc.

Hi there.
The touchpad drivers could be corrupt, try reinstalling the touchpad drivers again.
Go here to Toshiba Support fill in the details of your model laptop and download the synaptics touchpad driver and reinstall it, see if that helps.

Update synaptics driver from Hp.com that should fix the issue

Hi!
I resently had the same problem on my HP laptop and search Google for possible solutions. No solution works until I tried Windovs Update and then got 5 alternatives - Synaptics PS/2 port TouchPad was one of them. I update and restart and finally solve this problem.

Most laptops work fine with default Synaptics drivers: http://www.synaptics.com/support/drivers

Very useful for people who keep bumping their touchpad with their palm.

That's a sign that the synaptic touch pad needs to be replaced. Eventually they wear out.

Have you looked at the Device Manager to see if there's a problem with the touchpad?

Start -> Control Panel -> System -> click on Hardware tab -> click on Device Manager button. Do you see anything that indicates a problem with the touchpad?

Also, you might want to check the BIOS to see that the touchpad is still enabled. I doubt that this setting would have changed, but it's worth checking. When you boot the computer you should see a message that says something like: "To enter setup press XXX" where XXX is the delete key or some other key. Once you're in the BIOS poke around to see if you can find the settings for the Touchpad. Different manufacturers use different BIOS' so I cannot tell you exactly where to look.

Good luck.
