Given description and the replies from and , here is a safe, practical sequence to diagnose and try to recover the pad before buying parts or paying for service.

First, confirm software vs hardware:

  • Plug in a USB mouse so you can work comfortably. In Windows check Settings (or Control Panel > Mouse) to ensure the touchpad is enabled and look in Device Manager under “Mice and other pointing devices” for the touchpad driver; try uninstalling/reinstalling it. Many Inspirons also have a function-key or small switch that disables the pad—check for an icon near the F‑keys or a tiny switch by the pad.
  • To prove the pad is dead at the hardware level, test outside Windows (reboot and try in BIOS or boot a Linux live USB). If the pad never responds anywhere, it’s almost certainly a hardware problem.

Safe inspection and cleaning (if you choose to open the laptop):

  • Power off, unplug AC, remove the battery and wait until the system is completely dry. Do not power on while moisture or sticky residue may remain.
  • If you open the chassis, use the service manual for disassembly steps and an anti‑static precaution if possible. Carefully release the touchpad ribbon cable and inspect the connector and flex for sticky residue or corrosion.
  • Clean contacts with 90%+ isopropyl alcohol and lint‑free swabs; gently remove sugary/acidic residue. Allow everything to air dry thoroughly (24–48 hours) before reassembly.

When to replace or get help:

  • If reseating and cleaning don’t fix it, the pad assembly or its controller is likely damaged and should be replaced. Parts for the Inspiron N4110 are inexpensive and a local shop can fit them if you’re not comfortable disassembling the laptop.
  • While troubleshooting keep using a USB mouse and avoid powering the machine if you suspect internal moisture.

Sounds like you have killed the touchpad and need a new one fitted.

The sauce probably got into the system, shorting out the interface to the pad. You need to take the case apart and clean it up thoroughly.
