Advent laptop computers are equipped with a touchpad and two buttons that service the function of an external mouse. The touchpad can be turned on or deactivated, depending on the user's preference. It's not difficult to either activate or deactivate it.
Power up the computer. Connect a plug-and-play computer mouse to a free USB port on the laptop. The mouse is just temporary to help you get the touchpad working again. Locate the touchpad icon, which is in the lower right-hand side of the screen. The icon will appear as a gray square or rectangle, with two rectangular buttons underneath. Use the mouse to double-click on the touchpad icon, opening a window on your laptop screen. Inside the touchpad window, click the option labeled "Enable Device". Select other options for the touchpad, such as pointer speed and shape. Click "Apply", then "OK". Disconnect the mouse from the laptop.

Had a similar problem a couple of months ago, The left button started playing up, not working with every mouse click, it gradualy got worse till it was nearly unusable.. I suspected that the microswitch under the silver button had some dirt in it. After taking a deep breath I removed the battery and the screws that hold the case lower and upper halves together and was able to seperate the case front by about 3/4 of an inch. Then using a contact cleanerServisol Super 10 and supplied flexible straw I squirted cleaner into both mouse click buttons. After waiting for cleaner to evaporate and resecuring case halves and replacing battery I switched on .... The button works 100%..
some laptops have a switch that turns off the touch pad (usually a button right on the topside of the touchpad)
did you reboot completely? full shutdown, then power on?
goto the device manager (with a usb mouse of course) and find the touchpad... delete the device... then reboot again it should try and find the touchpad and ask for the driver, point it to the directory that you have the driver located.
If you have a wireless mouse or a USB mouse plug in and get online to find a downloadable driver for your touch-pad. A lot of file adding and shifting with a touch-pad can get the system fragmented (Defragging may help) and driver files, .dll's, and others your touch-pad needs and uses can get buried in the clutter (file fragments) all over the floor so-to-speak. If defragmentation of your hard drive doesn't work just download new drivers. Here is a safe Download link to look in. There is just about everything here, free and safe too...
