I've had this occur several times on different OQOs and this reset of the "Embedded Controller" seems to potentially resolve a frozen track point or unresponsive keyboard:
1. Boot into the BIOS (on boot, hit the 'delete' key (FN + BSP) repeatedly until you get into the BIOS screen)
2. Navigate to System Configuration > Restore OQO EC Defaults > NEXT BOOT
3. ESC to the main BIOS screen
4. Write to CMOS and Exit
This is speculative based on old oqotalk forum readings and my own testing, but there appears to be some sort of relationship (certainly on Windows 7) between OQO Manager communicating to the EC via ACPI, the Toshiba Bluetooth stack, and the track point. I haven't fully identified the relationship, however when the above steps didn't fix a stuck trackpoint, disabling Bluetooth in the BIOS and rebooting cleared the issue in at least one instance.
