USB IO Power Button Board Replacement for Dell G15 5510 5511 Gaming Laptop, Part Number TR4T5 0TR4T5 CN-0TR4T5 LS-K663P, Dual USB 3.2 Daughter Switch Panel with Power Control Function

This replacement USB IO power button daughterboard is specially engineered for Dell G15 5510 and G15 5511 gaming laptops equipped with RTX 3060 graphics, corresponding to official part numbers TR4T5, 0TR4T5, CN-0TR4T5 and board model LS-K663P.

It combines dual high-speed USB 3.2 interfaces and power switch circuit on one compact PCB panel, fully restoring two core laptop functions: external peripheral connection and system power-on control. All metal contact terminals adopt gold-plated anti-oxidation treatment to avoid common faults like unrecognized USB devices, intermittent data dropouts and unresponsive power buttons caused by aging original boards.

The circuit routing, screw hole positions and motherboard connector are strictly consistent with factory original components. No trimming, cutting or wiring adjustment is required during maintenance, supporting fast DIY replacement for computer repair shops and personal users. Each board undergoes strict functional testing after production to verify normal USB read/write speed and sensitive power key triggering performance.

Built with durable reinforced PCB and anti-interference electronic components, this IO board maintains stable long-term operation under gaming high-load conditions. It only matches Dell G15 5510 and 5511 RTX3060 models, not compatible with G15 5515, 5520, 5521 and other series laptops. Ideal spare part to solve damaged side IO panel, broken USB port and dead power button issues on Dell G15 gaming notebooks.
