If the touchpad is not coming on, it needs replacement. With a little bit of effort (or perhaps a lot of effort), the internal circuitry of the touch pad can be determined. This may require peeling it off of the front panel). Then, use resistors to jumper the proper contacts on the flex cable connector to simulate key presses. This should permit the functions to be verified before a new touch pad is ordered.If you are not comfortable doing this, I suggest call a technician. Your safety is most important.

Should you wish to know the part number for the touch pad, it is NAM02-00.

All the best!
