post the backup of the bios

Don't have any bios for it, the thing is I bought one with no screen but start up,
Than I forgot to save the old one and clear the chips both, and now I try both bios, (the ec bios for the 25l8006e, and the normal bios for the 25l6473e)
But now nothing happen no light on the powerbotten nothing)
What did I done wrong.?
And when I write the ec bios (1MB) it's say complete writing, but I I want try to read it (so I make sure, the writing was successful) nothing is on the chip.

I have a strange problem with this AIO. The hard disk is not recognised in the BIOS, but the HDD itself if removed and connected to another PC is recognised. I tried the same thing with another HDD, still the same. I thought there was a problem with a SATA cable or even the power connection so i changed the sata cable and gave power to the HDD from an external source. Still nothing. Then I tried upgrading the BIOS (with a windows live cd, because the procedure was to be done from within windows), and still nothing. Has anyone else ever had this problem. I'm considering buying the motherboard, but it should be an expensive solution

I've seen several AIO lenovo with problems in the sata power cable, you can try with another sata power cable, in my case the easy way to fix it is: cut the sata power cable by the middle and paste a working connector from another power supply, i hope this work for you.
