G580 CMOS/BIOS access failed, now black screen

I recently purchased a used G580, MN:  20157, SN:  WB08182885, BIOS:  62CN89WW, the system was equipped with Win 8, and 500 GB SATA HDD.  

I upgraded the RAM from 4 GB to 6 GB and the HDD to 250 GB SSD, and installed a new CMOS battery.  Now the system will not display any Lenovo logo nor can I access the BIOS setup, Boot Menu, nothing!  It's like the system just dropped dead.  I'm a certified system tech so all the standard and advanced troubleshooting was tried.... System gets power and HDD lights and webcam light comes on, you can heard CPU fan spinning, along with DVD drive spinning... but nothing else.  Am I looking at replacing the MB?  I saw a YT video of a guy looks like he removed the chip and resod onto the board.  I also heard this unit has two BIOS chips?  

Any help would be great.  My customer is waiting for pickup.  

 

Thanks Lenovo Community
