I poked around at mine for a bit, trying to see what I could find. None of the usual suspects like F2/F10/Del work, but Volume Up + Power brings you to a glorious menu with 7 options:

0 Enable Secure Boot
1 Disable Secure Boot
2 Boot USB First
3 UEFI Menu
4 EC Version
5 Reboot
6 Shutdown

I'm not sure what will qualify as a valid disk test, I'm all ears though. I fear anything running through the x86 translation will skew the results. And using dd in the Subsystem for Linux isn't really exercising the block layer. Suggestions?
