Describe the bug

Official Framework 240W charger is stuck at 100W SPR instead of 240W EPR. Battery discharges under GPU load despite charger being connected.

Steps To Reproduce

1. Connect official Framework 240W charger to any USB-C port
2. Run journalctl -k | grep ucsi
3. Check sink caps: cat /sys/class/typec/port*/usb_power_delivery/sink-capabilities/*/desc

Expected behavior

Charger negotiates EPR at 48V/5A = 240W.

Operating System (please complete the following information):

• OS/Distribution: Arch Linux with Hyprland.
• Version: Linux fw16 6.19.6-arch1-1 The link in "Framework Laptop 13 Intel Core Ultra Series 1 BIOS 3.04 BETA Release" is wrong #1 SMP PREEMPT_DYNAMIC Wed, 04 Mar 2026 18:25:08 +0000 x86_64 GNU/Linux

Additional context

The EC returns unknown error 0 on GET_CABLE_PROPERTY:
ucsi_acpi USBC000:00: unknown error 0
This prevents the kernel from reading the cable e-marker. Without confirmed 5A capability, the PD stack never requests EPR mode and the charger never reveals its 48V PDOs.

Sink caps via /sys/class/typec/:
variable_supply 20000mV / 5000mA = 100W max
No EPR PDOs present. Charger source caps never show 48V entries. Whether the root cause is EC firmware, ACPI, or kernel driver is unclear.
