Replacement I/O SubBoard for Satellite A660 A665

This SMUGDESK LS6064P USB audio jack board is a dedicated replacement I/O subboard for Toshiba Satellite A660, A665, P750 and P755 laptops. It integrates dual USB ports and a combined 3.5mm headphone and microphone jack on a single circuit assembly. The part arrives new with a preattached flexible ribbon cable matching the original NWQAA specification. It is intended for repair technicians and owners fixing failed side-panel connectivity.

Installation requires full laptop disassembly

The board is a plug-in replacement that requires no soldering; the original ribbon cable disconnects from the motherboard and the new unit connects in its place. Professional disassembly is recommended because the subboard sits behind the chassis plastics and keyboard deck. The most common issue is ordering the wrong part number, so verifying LS6064P or NWQAA against the original board before purchase avoids fitment problems.

Restores reliable port function under daily use

Once installed, the dual USB ports and audio jack operate as the factory design intended, handling repeated insertions and continuous peripheral loads. The ribbon cable is routed to match the original layout, preventing strain that could cause intermittent contact over time. This repair addresses loose jacks, dead USB ports and total audio loss permanently. It does not add extra ports or upgrade the USB signalling standard.

Questions about this item

How can I confirm the LS6064P board is functioning after I install it?

After fitting the board, plug a USB device into each port and verify the laptop recognises them, then connect headphones and a microphone to the 3.5 mm jack and check for sound output and input.

What comes with the LS6064P board and is anything else needed?

The board ships with the matching flexible ribbon cable already attached; no extra cable, connector or solder is required for the swap.

Which part number should I match to my Toshiba Satellite before ordering?

Look for the original part number LS6064P or NWQAA on the existing I/O subboard and confirm your model is A660, A665, P750 or P755.
