There are several ways to address issues with a touchpad’s left-click without replacing the entire touchpad. Checking that the touchpad is enabled and that the left-click function is configured correctly can help. Updating, reinstalling, or rolling back drivers may resolve software-related problems, while adjusting sensitivity or click settings in the operating system can improve responsiveness. Cleaning around the touchpad buttons to remove dust or debris can help with mechanical issues, but it should be done gently to avoid damage. External devices, BIOS/UEFI settings, or internal hardware connections can sometimes affect functionality. Even with these steps, some problems may persist if the touchpad is physically worn or damaged, in which case replacement may be necessary. There may be additional factors depending on the specific device or system.
