Hi all I have lenovo B560 it dos not work , I had used SPI flash programer to programming its BIOS chip and EC chip ,
the operation has been succeeded but some times it dos not shunt down properly , and when it restart , it take about 15 seconds to restart .When I had entered the bios using keyboard ,
I have found the BIOS version is 39CN16WW and EC version is 39CN12WW ,so is this difference between version cause that problem ? I hope any one could send BIOS image file and EC image file (same version) to my Email and thanks so much........

Here U will find proper main BIOS (it will fix Your shutdown poblem)
