Precision 7720 Palmrest Junction Board

This genuine Dell circuit board sits beneath the touchpad palmrest assembly in Precision 7720 and Precision 7520 laptops. It carries the DPN identifiers FX6M6 and 3PJ1V along with alternate part numbers CAP10 and LS-E325P. The component is supplied new and is an original Dell OEM part.

Suits Precision 7720 and 7520 palmrest repairs

Technicians replacing a damaged junction board in the listed models will find the correct fit and connector layout. Builders working on other Dell series or non-Dell chassis should look elsewhere because the mounting points and flex-cable pinouts are specific to these two model numbers.

DPN FX6M6 and 3PJ1V confirm the exact variant

Match these two codes against the label on the original board before ordering; they are the only identifiers that guarantee the right revision for the Precision 7720 or 7520 palmrest assembly.
