I'm trying to help someone upgrade their XO-4 Touch to the latest firmware (Q7C05) but this isn't working, seemingly blocked by the EC which cannot detect good white batteries inside this XO (each white battery's we tried is fully charged, as verified by other XO's).
The ok prompt announces this XO-4 has firmware Q7B23 but when running "menu" at the ok prompt, manufacturing tag BV is set to Q7B01 FWIW. When running "watch-battery" at the ok prompt, it responds: EC command result timeout When clicking on battery within http://wiki.laptop.org/go/XO_Self_Test the screen goes all red, showing: Testing /battery Selftest failed due to abort When running "test /battery" at the ok prompt, it responds: No selftest method for /battery Any workarounds or things to try, regardless whether EC (Embedded Controller 0.3.04) or some other hardware issue on this very early XO-4 Touch might somehow be to blame? Thanks for ideas!
