Were you able to update your firmware?
Here is a fix that appears to work on the rollover to 2011 loss of keyboard and mouse:
XO-1s running Builds 650, 653 and 656 when rebooted in 2011:
- download http://dev.laptop.org/pub/firmware/q2d14/bootfw.zip
- place on a USB memory stick, in a folder/directory named "boot":
- boot your XO-1 with the USB stick inserted, and confirm this signed
firmware upgrades successfully, from Q2D06 or Q2D07 to Q2D14 (2 reboots
might be required)
- remove all power from your XO for 30sec (battery AND power cord)
Please do report back if this fix works for your issue.
