  Replace the touchscreen digitizer

  Why it's wrong here

  Replacing the touchscreen digitizer is a drastic hardware repair that should only be considered after exhausting all software and driver-related troubleshooting steps. A digitizer replacement implies a physical defect or damage, which is a less common initial failure point for a brand-new all-in-one PC compared to configuration issues. Performing such an invasive and costly repair prematurely would be inefficient and potentially unnecessary, as driver problems are far more prevalent.

  Check if the touchscreen driver is installed in Device Manager

  Why this is correct

  Checking Device Manager for the touchscreen driver is the most logical and effective first step because drivers are essential software components that enable the operating system to communicate with and control hardware devices. If the driver is missing, corrupted, or incorrectly installed, the touchscreen will not function, regardless of its physical integrity. Device Manager provides a centralized interface to verify driver status, update drivers, or identify hardware conflicts, making it crucial for initial diagnostics.

• ✗

  Clean the screen with a microfiber cloth

  Why it's wrong here

  Cleaning the screen with a microfiber cloth is a superficial maintenance task that addresses cosmetic issues like smudges or dust, not fundamental hardware or software malfunctions. While excessive dirt might occasionally interfere with touch sensitivity, it is highly unlikely to cause a complete and total non-responsiveness of the touchscreen on a new device. This action does not diagnose or resolve underlying driver or hardware component failures that prevent the touchscreen from registering input.

• ✗

  Disable and re-enable the touchscreen in BIOS

  Why it's wrong here

  Disabling and re-enabling the touchscreen in BIOS is generally not a primary troubleshooting step for a non-functional touchscreen on a new all-in-one PC. BIOS settings typically control the fundamental enablement or disablement of integrated hardware components at a very low level, but they rarely cause a specific peripheral like a touchscreen to fail if it's enabled. Driver-related issues within the operating system are significantly more common culprits for such problems than incorrect BIOS configurations, making this a less probable initial solution.
