Precision 7710/7720 Base Assembly with USB-C
This genuine Dell OEM bottom base assembly replaces the lower chassis on Precision 17 (7710) and Precision 17 (7720) laptops that already feature the optional USB-C port. The part includes the integrated USB-C port cutout and the Smart Card reader slot. A battery bay spring latch is supplied with the assembly.
Direct Replacement for Damaged Lower Chassis
Install this assembly when the original base is cracked, the USB-C port housing is broken, or the Smart Card slot is misaligned. The jump is worth it if the laptop frame is bent or the port mounting points have failed, restoring structural rigidity and port alignment without replacing the entire system.
For Technicians Repairing 7710 or 7720 Models
This part suits repair shops and owners servicing Precision 17 (7710) or Precision 17 (7720) units that shipped with the optional USB-C port. It is not for laptops lacking that factory option, nor for other Dell series, because the port cutout and internal mounting points differ.

Questions about this item
Does the 4M07T bottom base assembly align with the existing screw points on a Precision 17 (7710) chassis?
Yes, the Dell OEM base is built to the original factory layout for the Precision 17 (7710) and (7720), so the mounting holes and standoffs match the chassis without modification.
Which step is most often missed when fitting the replacement base on a 7710 or 7720?
Transferring the battery bay spring latch from the old base to the new one; the latch is included but must be moved over during the swap.
Will the Smart Card reader slot in this base require a separate module later?
The slot is moulded into the assembly; only the Smart Card reader board itself needs to be reinstalled or replaced if it fails.
