S3 Sleep sometimes takes a few minutes to activate; crashes upon wakeup if any USB3 storage devices are mounted.
All integrated and external PS/2 devices work and are independently configurable.
The 2-button PS/2 pointing stick is identified as a "PS/2 Generic Mouse", and works best if libinput is installed and reconfigured to provide scrolling while the right-button is held; I cannot get middle-button emulation working on the pointing stick, despite using this configuration successfully with Debian 9.
The PS/2 Synaptics touchpad defaults to middle-button emulation and fully supports 2-finger gestures.
Integrated 3D accelerometer could be useful for detecting and defeating "snatch-and-run" attack.
Integrated fingerprint scanner lacks driver support for Linux.
CPU and GPU are both (theoretically) upgradable.
