Restore Your Asus Laptop's Power-On Functionality

What Does the Power Board Do?

The Asus power board is responsible for managing power delivery from the charger to the motherboard. It houses the laptop's power button, LED indicators, and in many models, handles the charging path and switch logic. When your laptop won’t turn on, the power button doesn’t respond, or LED indicators fail to light up, a damaged or disconnected power board may be the root cause.
This modular board enables clean, solder-free repairs that avoid disturbing your mainboard. It’s a vital part in models where power circuits are routed through a dedicated daughterboard rather than being soldered directly to the logic board.

Top Benefits of Replacing Your Asus Power Board

1. Restores proper power-on and shutdown control.
2. Re-enables charging LED indicators and status lights.
3.

OEM fit ensures secure switch alignment in the chassis.
4. Avoids full motherboard replacement and high repair costs.
5. Resolves stuck, loose, or dead power button symptoms.
6. Maintains safe and stable power delivery to the laptop.
7. Quick plug-and-play installation—no soldering required.
8. Includes 12-month warranty for peace of mind.
Typical failures include no power response, shorted button circuits, cracked board housings, or torn ribbon cables. This board is a precise solution when the laptop is otherwise functional but fails to respond to the power button.
