Update: After draining the battery (disconnect the power supply, connect USB devices to charge them and... wait), the PC was able to restart normally. The BIOS indicates well version 2.22. For the parameters, the only visible change is that the password requirement has changed from "always" to "setup". Now, how can I check the integrity of the installed Bios? Since the update of the Bios could take place at least until the EC block verification (where it crashed), it seems that only the "/L" was not done (program all ROM Holes); is this a problem? Thank you Michel
