Replacement board for Lenovo IdeaPad 3 15IAU7

This board replaces the original side I/O assembly on Lenovo IdeaPad 3 15IAU7 (82RK) laptops. It combines a USB port, power switch button and SD card reader into a single circuit board. The part matches OEM numbers 5C50S25335 and NSE342 for direct substitution. It is intended for repair technicians and owners fixing a damaged I/O board.

Verify model number and connector before ordering

Confirm that your laptop carries the exact model designation IdeaPad 3 15IAU7 with the 82RK identifier. The board fits only that chassis and connector layout; other 15-inch IdeaPad 3 variants use different part numbers. Inspect the existing board for physical damage or liquid residue that could affect the new installation. No soldering or firmware changes are required for the swap.

Restores USB, power button and SD card functions

The integrated design returns all three side-panel features in one replacement step. A working USB port reconnects peripherals such as mice or flash drives. The power switch button restores normal on/off control. The SD card reader re-enables direct media access from cameras or other devices. Installation uses the original mounting points and ribbon connector for a plug-and-play fit.
