Fix Charging Problems with a New Asus DC Power Jack Board

Why Replace the DC-In Power Jack Board?

The Asus DC power jack connector board provides the essential link between your laptop's AC adapter and the internal power circuitry. When the jack becomes loose, intermittent, or sparks during use, it's not just inconvenient—it can cause internal board damage or permanent power loss. Replacing the full DC jack daughterboard is the safest and most effective fix for charging instability, flickering power, or burnt connectors.
This board securely mounts the DC barrel jack to the chassis and ensures stable current delivery, preventing stress and solder damage to the motherboard. It’s a cost-effective, OEM-quality solution to keep your laptop powered up and reliable.

Top 8 Benefits of a Genuine Asus DC-In Board Replacement

1. Stops random shutdowns and charging loss when the cable moves.
2. Replaces wobbly or cracked jacks that no longer hold the plug securely.
3. Eliminates visible sparks, overheating, or shorting during connection.
4. Prevents further damage to power flex cables or system boards.
5. Avoids risky motherboard soldering with a modular board replacement.

Symptoms like "laptop powers off when plug is touched" or "Asus not charging despite new charger" are common signs of jack failure. Replacing the DC power connector board resolves these safely and reliably.
