XPS 15 9530, PD 3.1/EPR

I paid $3,000+ for an XPS 15 9530 and discovered something frustrating:

• The Embedded Controller (EC) only negotiates Dell’s proprietary 130 W SPR extension, not proper USB Power Delivery 3.1 / Extended Power Range (EPR).

• With the official Dell brick, the laptop pulls ~130 W (20 V @ 6.5 A) — a non-standard trick that works only with Dell hardware.

• With a standard 140 W PD 3.1 charger, the system falls back to 15 V @ 4.5 A (~67 W), because the firmware never exposes EPR PDOs.

So let’s be clear:

• The hardware is capable (it already runs >100 W with Dell’s charger).

• The firmware deliberately blocks EPR.

• Users are being forced into buying Dell chargers when the open PD 3.1 standard already exists.

To make matters worse:

• Dell’s charger has a fixed cable. When it fails (and they do), you can’t replace it. That’s designed e-waste and extra cost on top of the thousands we’ve already paid.

• If Dell cared about users, the brick would have a detachable USB-C cable like most modern PD 3.1 chargers.

Other manufacturers (Framework, Lenovo, ASUS, etc.) are already enabling PD 3.1 up to 240 W. Dell is lagging behind — and worse, deliberately restricting features the hardware can support.

👉 Dell: do the right thing. Push out a BIOS/EC firmware update that enables PD 3.1/EPR on the XPS 15 9530. Stop forcing us into your overpriced, proprietary chargers.
