Genuine Dell Inspiron 7573 daughterboard

This original Dell part combines the power button, USB ports and card reader on a single green daughterboard. It carries part number 23G91 and is built for the Inspiron 15 7573 2-in-1 chassis. The board restores front-panel I/O and power control when the original fails.

Sustained daily insertions and button presses

The USB and card-reader contacts are rated for repeated mating cycles typical of laptop use. The tactile power switch maintains consistent actuation force over thousands of presses. No active cooling is required, so thermal throttling does not occur during continuous peripheral access.

Replaces a faulty THB02 board in the 7573

Swapping this daughterboard fixes dead USB ports, unreadable memory cards or a non-responsive power button. The repair is worthwhile when the mainboard and display remain functional. It is not for users needing additional ports beyond the factory layout or those servicing a different Dell model.

Questions about this item

How much power does the THB02 23G91 daughterboard draw when the Inspiron 7573 runs all day?

The power button, USB port and card reader on this daughterboard draw only a few watts combined, so they add negligible heat to the 15-inch chassis.

Which internal cable or connector must the laptop already have for the 23G91 board to plug in?

The board mates with the existing motherboard header on the Dell Inspiron 15 7573; no extra cables or adapters are required.

Will the green THB02 card reader work with older SD cards I used in a previous Dell laptop?

Yes, the reader supports standard SD formats, so legacy cards from earlier Dell models will read and write normally.
