Dell XPS 15 Battery Cable 503K4

This genuine Dell flex cable carries the battery power status LED and dual-array microphones for XPS 15 9550, 9560 and 9570 models. It also fits Precision 5510, 5520 and 5530 workstations. The part number is 503K4.

Sustained Operation Reliability

The cable routes under the palmrest where heat and repeated flexing occur during daily use. OEM construction matches the original routing and connector tolerances so signal integrity for the LED and microphones remains stable over long sessions.

Compatibility Check Before Ordering

Confirm your service tag matches one of the listed XPS 15 or Precision models before purchase. This cable does not support other Dell 15-inch series or earlier XPS generations. Professional installation is recommended due to palmrest removal.

Questions about this item

Does the 503K4 cable generate any heat or noise during continuous use?

The cable is a passive flex assembly carrying only battery-status LEDs and dual-array microphones; it draws no measurable power and produces no audible noise or heat.

What laptop model must I already own for this 503K4 cable to fit?

It fits Dell XPS 15 models 9550, 9560 and 9570 and Precision 15 models 5510, 5520 and 5530.

Will the 503K4 cable work if I keep my original palm-rest assembly on a Precision 5520?

Yes, the cable sits on the underside of the palm-rest assembly, so it installs directly beneath the existing palm-rest on a Precision 5520.
