Atma has reset the Idea-pad now (reinstall of windows and delete of all apps), finished the undertaking.
It seems that the keyboard now works again (currently writing with it).
Since like mostly, when buying computers in Cambodia, they come along with a set of "standard" robber-copies of software, Atma will now install the sangha-given softwares,
Libreofffice and
notepad+ of which had always been enough till here, for the last an many year+ to maintain this host and sort Dhamma-Dana.
It wouldn't be complete if not noting the pleasure/ease to work in a clean environment.
