Fix Power-On and Charging Failures with a Genuine Asus Power Board
Reliable Solution for Laptop Power Issues
If your laptop no longer powers on, shows no charging light, or behaves unpredictably when plugged in, the Asus power board may be the issue. This vital component manages power input, the power button response, and charging signals from the adapter or USB‑C port. A failed power board can lead to no LED activity, boot loops, or complete power loss.Typical symptoms include "charging LED doesn't light," "power button unresponsive," or "charging only works when adjusting plug angle". Rather than replacing your entire motherboard, installing a replacement power board offers a quick, affordable solution with OEM performance.
