These laptops are the same as the already known 14-fe0xxx models, but
with a Purwa SoC, SKU number 14-fe1xxx. [1]

The supported features are the same as for the original Omnibook X14:

- Keyboard (no function keys though)
- Display
- PWM brightness control
- Touchpad
- Touchscreen
- PCIe ports (pcie4, pcie6a)
- USB type-c, type-a
- WCN6855 Wifi-6E
- WCN6855 Bluetooth
- ADSP and CDSP
- X1 GPU
- GPIO Keys (Lid switch)
- Audio definition (works via USB and with internal speakers)
