Lenovo ideapad 100 needs some tweaking before we can enjoy it.

BIOS Hack

In BIOS change “OS Optimized Defaults” to “Win8 64bit” and loaded defaults.

Disable Secure Boot, then change “OS Optimized Defaults” back to “Other OS” - but do not load defaults.

Suspend, resume, reboot and shutdown should work well.

SD Card Reader

Package rts5139-git from AUR has to be installed.
