The touchpad on a Dell laptop is usually located under the keyboard. Moving the finger on the pad moves the pointer on the screen. The buttons near the pad act as a right and left click. Windows includes a method to troubleshoot the touchpad. In addition, if the touchpad is still giving you issues, Dell recommends draining the "flea" power the standby power from the computer to restart it. Both methods are simple and only take a few minutes.
Open the control panel from the Start menu. Click on "Mouse." This will open a window with several tabs. On the first tab, click the touchpad to open a new window to change the settings for your touchpad. You can customize the settings to how you want your touchpad to work. If this does not solve your issue, proceed to the next step. Click the Hardware tab on the screen that pops up. Select the Dell Touchpad and click "Troubleshoot." A new window will open with the Windows Help and Support Center to bring you through methods for troubleshooting the touchpad. Follow the methods described until your touchpad is working properly.
Drain flea power Shut down the laptop and disconnect all external devices, such as a thumb drive, headphones and the AC adapter power cable from the system. Take the battery out of the laptop. Hold down the power button for at least 5 seconds without releasing it. Return the battery back to the laptop. Power the system on. If your touchpad still is not working properly, call Dell for customer support.

Dell Inspiron 1525 Touchpad That Is Not Working
Turn your Inspiron 1525 off and remove any power cables that are connected to the device. Close the computer, turn it over and slide the battery lock button down to release the rectangular battery from its compartment on the underside of the computer. Turn your laptop right-side up and open the computer so the monitor is facing you. Insert the tip of your flat-head screwdriver in the seam between the plastic keyboard guard and the side of the computer. The keyboard guard is located just above the keyboard. Pry up on the guard until it pops out of place. Be sure to do this gently, as you do not want to damage the guard. Remove the guard from the computer and set it aside. The two keyboard screws will now be visible underneath where the guard used to sit. Use your Phillips screwdriver to remove the two keyboard screws and use the tips of your fingers to lift the keyboard up from the top. Place the keyboard facedown over the touchpad and locate the thick connector ribbon that runs from the motherboard inside the computer to the back of the keyboard. Use your fingers to gently unplug the ribbon from the back of the keyboard and set it aside. Insert the tip of your screwdriver in the seam at the bottom of where the keyboard used to rest and gently pry it up. This will release the top plastic frame from the Inspiron, revealing all of the broken touchpad. Use your fingers to disconnect the thick ribbon from the side of the damaged touchpad and slide the touchpad out of the Inspiron. Slide the new Touchpad (available from your Dell retailer or online) in its place, fit the top frame in place and reassemble the computer in the reverse order you took it apart in.
