Hello, Following a keyboard problem, I downgraded the "BHCN42WW" bios with the "BHCN27WW" version. I did not have an error message, however The computer is found with a black screen and the power light blinking. I got here the BIN file version BHCN38WW to reprogram the eprom. The computer is working again, but I still have the same keyboard problem. it must be reset with "Fn + s + v" at each start. But the other problem is that now in the bios I no longer have the name or the serial number of the motherboard! How to do ? In attached file I put the old saved bios
Attached Files
File Type: rar BHCN27WWold.rar (5.34 MB, 20 views)
