Suitable for Precision M6800 repairs

Technicians restoring a Precision M6800 with damaged or non-functional left-side connectivity will find this direct replacement part. It is not suitable for any other Dell model or laptop series, nor for desktop motherboards requiring a similar I/O function. Buyers needing right-side ports, internal headers, or a different form factor must source the correct alternative board.

Dell part number 1PN90 confirms fit

The single specification that guarantees compatibility is the Dell part number 1PN90 stamped on the board. Only the Precision M6800 is listed as a compatible system in the manufacturer data. Verifying this number against the original component is the only way to ensure the part will install and operate correctly.
