Finally, here is the working dump for boards with U1 chip only, after I remove the password, the custom logo and update it to the latest version A15.
For more BIOS'es problems you can always contact me at [email protected] or [email protected]
Tested and works 100%. Same as new.
Enjoy

You can download bios above.

 

[Ciprian Baroncea]

Yes i`ve seen that. but if i will flash the bios chip... it will fix the u7 ?

That depends on your computer is damaged. I can not identify ( you can test )

Thanks

Ok. I`ll tell you the hole story. So i bought this laptop ..that had a bios password. We tried to remove it ..but to be honest I`ve never flashed a bios chip. There was very hard to find a schematic..or anything that could help me to identify the bios chip. Until then a friend of mine toke the u7 chip and wiped. After that I was aleardy waiting the new chips with the bios already flashed. But because the u7 chip is wiped..it starts but will not boot or show anything on screen because of that chip. Is it worth fixing or shall I just buy another one? I`m a tehnician ..but this is the only thing i`ve never done ..like bios chips. thank you and sorry for bodering you.

Thank you,
With respect Ciprian Baroncea.
