ASUS A455L Drivers, Boot Errors, and Device Failures
The ASUS A455L driver set allows Windows to communicate with internal hardware components including the battery controller, touchpad, and display system. When devices stop responding or the system fails to boot correctly, drivers are often assumed to be the cause, but in many cases the behavior relates to power state failures, hardware faults, or internal component issues rather than software.
This page provides ASUS A455L driver context together with troubleshooting notes describing situations where the battery does not charge, the touchpad is not detected, or the system powers on without producing any display output.
Problem: ASUS A455L battery shows 0% and does not charge
What users observed: After a period of inactivity, the laptop powered on only when connected to AC power. The battery remained at 0% with no increase, and the system shut down immediately when the charger was removed.
What was tried: Users attempted power cycling, reconnecting the charger, and reseating the battery. In some cases, a brief charging indicator appeared at startup before stopping.
How this played out: The system continued to behave as if no battery was present. Charging did not resume, and the battery level remained fixed at 0% with no recovery observed.
Problem: ASUS A455L touchpad not detected and cannot be enabled
What users observed: The touchpad could not be enabled using function keys, and the system reported the device as disconnected hardware despite it being built in.
What was tried: Users checked driver status and device visibility within system settings, expecting the issue to be related to missing or incorrect drivers.
How this played out: The touchpad remained unavailable and unusable. The system continued to report it as not connected, and the issue led to hardware replacement in cases where no recovery occurred.
Problem: ASUS A455L powers on but shows black screen with no display
What users observed: The laptop powered on with normal indicator lights, including a solid white power light. The screen remained completely black, and a steady internal noise could be heard. No image appeared on the built-in display.
What was tried: Users performed power resets, attempted startup on AC power only, reseated memory, and tested external displays.
How this played out: No display output appeared on either the internal or external screens. In some cases, disconnecting and reconnecting power temporarily changed behavior, but the issue returned. The condition did not resolve through driver or software changes and was suspected to extend beyond the operating system.
Across ASUS A455L troubleshooting reports, the recurring pattern is that battery failures, missing input devices, and no-display boot issues are typically not caused by drivers. Instead, these problems commonly trace to power delivery faults, internal hardware disconnection, or component failure, where driver reinstall attempts do not change system behavior.
