I managed to fry my board, but before that I noticed the same problem with the RAM voltage line. It was 0.3V instead of 1.2V. I don't think the BIOS is the culprit.

It is late reply... What you should do, is put the original charger in the laptop and get a powersuplly with 1,2volts on the rail you are getting the 0,3v. Check the amps and try power it on with keeping the powersupply on the rail. This could be a ram issue but can also be a controller issue. If it would be a shorted cap you wouldnt have 0,3V. I hope this info helps for someone who encounters this problem. Be carefull with amps you put in!

Thank You.
But problem still exists - I used NeoProgrammer V2.2.0.10
Writing both BIOS chips was successfull: The CRC32 checksums were the same as the file's ones.

On the motherboard the DUAL BIOS chips are printed like this:

JBIOS 1: W25Q128JVSQ (16mb)

JBIOS2: W28Q64JVSIQ (8mb)

I attach a copy of the bios
