M82 fails to boot following BIOS flash

After flashing an M82 ThinkCentre BIOS using the M82 flash for Spectre/Meltdown the system failed to restart.  The failure mode is that upon application of power (plugging in the AC), the CPU fan will spin and you can hear the DVD drive try to start.  After several seconds, everything spins down and the cycle repeats.  Nothing appears on the display; there are no error codes (beeps or otherwise).  We have attempted to clear the BIOS several times by removing the BIOS jumper, removing the CMOS battery and gone so far as to pull the motherboard and removing all components to resent. The failure mode remains the same.  Looking for input on any other way to clear or reflash to BIOS.

Re: M82 fails to boot following BIOS flash

Burn a bootable CD with CD ISO image, and follow directions exactly for "recovering from a failed BIOS update" in the HMM.  May take multiple tries.

Google for "lenovo, M82, bios", and see the "Read First" pinned thread above for HMM.
