System Details

  • Device: Yaviks (15a-nb0013dx)
  • OS: Fedora Linux 44 (Workstation Edition)
  • Firmware Type: UEFI Full ROM
  • Firmware Version: MrChromebox-2603.2 (05/17/2026)

Summary of the Issue

[Briefly describe what is happening]

I recently switched from CachyOS to Fedora. On CachyOS charging worked fine after adding an ACPI flag to the grub config. After switching to Fedora, even with that same ACPI flag and the cros_ec_typec loading fix, I noticed my charging speed would drop from the typical ~30W to ~7W.

Doing an EC reset (Refresh + Power) fixes it temporarily, but it breaks again the next time the charger is connected.

ectool chargestate show shows chg_current = 100mA locked after charger connect.

I’m not sure if it’s a firmware issue, but I did recently upgrade it from the April release.

Steps to Reproduce

  1. EC reset to start from a clean state.

  2. Check if charging is working normally with sudo ectool chargestate show, chg_current should be above 100mA

  3. Unplug and wait a few secs

  4. Plug the charger and run sudo ectool chargestate show again, chg_current will be stuck at 100mA

Expected Behavior

After plugging in the charger, the EC should negotiate a proper PD contract and charge around 30W.
