0T981T LS-B758P USB Audio IO Board with Cable, OEM Replacement CN-0T981T T981T DC02C009G00 Side Port Daughterboard for Dell Alienware 17 R3 Gaming Laptop Repair

This USB audio side IO board is a factory-matched replacement component marked part numbers 0T981T, CN-0T981T, T981T and LS-B758P, specially designed for Dell Alienware 17 R3 gaming laptops. The full set includes the IO circuit board and original compatible ribbon cable DC02C009G00, eliminating the trouble of separate cable matching during maintenance.

The daughterboard carries two standard USB ports and dual 3.5mm audio jacks for headset and microphone, restoring full peripheral connection capability when the original board suffers from port damage, liquid corrosion or internal circuit failure. Every board undergoes strict power and signal testing before shipment to ensure stable data transmission and lossless audio input/output without static noise or intermittent disconnection.

It retains the original factory PCB layout, mounting hole positions and connector pinout, perfectly fitting the side slot of Alienware 17 R3. Users only need to disassemble the laptop shell, unplug the faulty old board and install this replacement directly without soldering, wire cutting or structural modification.

Instead of replacing the expensive whole motherboard, this dedicated IO board greatly reduces laptop repair costs, ideal for computer repair shops, DIY hardware enthusiasts and personal Alienware 17 R3 maintenance. The reinforced ribbon cable features anti-fracture wrapping to prevent loose contact and short circuit after long-term frequent use, bringing back reliable daily USB and audio performance for your gaming notebook.
