Sometime during the flash process, the EP121 just shut off. I was not watching bit-by-bit what was happening, so I'm not sure if this was during the end of the process or the middle of the process that it happened. The charge light remained on, even when I unplugged my power supply. I used the pin between the two USB ports, and that resulted in the charge light turning off, but now when I plug the power supply back in, the charge light does not light up. Toggling the power button does not appear to do anything. My machine simply won't power on with the usual buttons. Is there any emergency BIOS recovery routine or keypress combination? Thanks.
