Genuine Dell IO Board for G3 3779

This is a new original Dell IO circuit board designed for the G Series G3 3779 laptop. The part number is 110K9 and it integrates a USB port, an SD card reader slot and the CMOS battery cradle. It replaces a damaged or faulty daughterboard inside the chassis.

Direct replacement for the factory daughterboard

The board fits the G3 3779 without modification and restores the side USB connection and SD card slot. It also provides the correct mounting point for the CMOS battery. Installation requires opening the laptop case and disconnecting the existing board.

For owners repairing a G3 3779

This part suits anyone fixing a broken USB port, dead card reader or missing CMOS holder on that exact model. It is not for other Dell series, different G3 model numbers or any non-Dell laptop. Buyers needing a different port layout or extra connectivity should look elsewhere.

Questions about this item

Does the USB port on this 110K9 board provide enough power for a portable hard drive?

The board carries a single USB port and an SD card slot; power delivery matches the laptop's original specification for that port.

Will the CMOS battery cradle on the 110K9 board overheat during continuous use?

The cradle is a passive holder for the coin cell and generates no heat of its own.

Must my G3 3779 already have the CAL73 daughterboard installed for this part to fit?

This 110K9 board replaces the existing IO daughterboard directly; no additional parts are required.
