What should I do if the buttons don't work in my daily life?
1. Check the touchpad settings:
Verify if the touchpad is disabled: some notebooks are equipped with a touchpad switch or shortcut key to enable or disable the touchpad. Usually, pressing a specific key combination on the keyboard (e.g. Fn+F6, Fn+F10, etc., depending on the laptop brand and model) will toggle the status of the touchpad.
2. Restart your laptop:
By restarting your computer, the system will reload and return to its normal state, which will help to solve the touchpad abnormality problem.
3. Update the touchpad driver:
Uninstall the current driver or install the latest driver.
Touchpad Cleaning
If there is dust, dirt or liquid on the surface of the touchpad, it may affect the normal operation of the touchpad.
Use a clean cloth or paper towel to gently wipe the surface of the touchpad to remove dust and dirt. （Be careful not to use cleaners containing harsh ingredients such as alcohol or chloroform to avoid damaging the touchpad.）

Dell has videos of laptop disassembly and replacement. Pretty easy fix.
