Mistake, eh? You do realize (now) that your mouse and keyboard are connected via USB?

You should have keyboard and mouse connected. I have not tested this, but it should work.
Thank you for submitting your question on this Intel® Community.
Based on the description of the issue, the troubleshooting performed, and the steps recommended to address this problem, there is little we can do to further assist you. The options available to set BIOS settings back to factory default values require a keyboard.
In this scenario, it is worth mentioning that opening the unit voids the warranty.
If this issue occurred in more than one unit, and you did not open the unit, then our recommendation is that you contact Intel Customer Support in your region. Keep in mind that additional information may be required.
