Asus A455L laptop – Troubleshooting Notes (DriverFiles)
Most cases recorded here started with the assumption that the Asus A455L was failing due to a driver or software problem. What followed was often less clear. In several situations, driver-related changes had no effect, behavior contradicted expectations, or the issue appeared rooted in hardware or power states rather than anything the OS could correct.
Problem: Battery shows 0% available and never charges
What users observed: After weeks of inactivity, the laptop powered on only when connected to AC power. The battery remained at 0% indefinitely, showed no charging progress, and the system shut off immediately if the charger was removed.
What was tried: Power cycling, reconnecting the charger, and reseating the battery were attempted. Brief charging animations appeared on startup, then stopped.
How this played out: The system continued to behave as if no battery was present. No recovery or charging behavior was reported afterward.
Problem: Touchpad permanently disabled with hardware not detected
What users observed: The touchpad could not be re-enabled using function keys. In device settings, it appeared as disconnected hardware even though it was a built-in component.
What was tried: Driver state and device visibility were checked, but the system continued to report the touchpad as not connected.
How this played out: The touchpad remained unusable. No permanent solution was identified, leading to the replacement of the hardware component.
Problem: Laptop powers on but remains on a black screen with audible noise
What users observed: The charging indicator lit normally, and the power light turned solid white after pressing the power button. The display stayed black, and a steady internal noise was audible. No image appeared on the built-in screen.
What was tried: Power resets, AC-only startup, memory reseating, and external display testing were suggested and attempted.
How this played out: The system did not display output on either the internal or external screen. Unplugging the entire system and reconnecting provided a temporary solution to some.The problem was suspected to extend beyond software or drivers, but no confirmed resolution followed.
