- Both DIMM slots with 5200 MT/s memory
- Both M.2 SSD slots
- All USB ports
- Webcam
- Ethernet
- WiFi/Bluetooth
- Integrated graphics using Intel GOP driver
- Internal microphone
- Internal speakers
- Combined headphone + mic 3.5mm audio
- 3.5mm microphone input
- S3 suspend/resume
- Booting Pop!_OS Linux 22.04 with kernel 6.2.7
Not working:
- Discrete/Hybrid graphics
- Thunderbolt
