Lenovo IdeaPad U160-M436GGE 0894 33CN14WW BIOS needed

Dear BIOS Gurus!

Im in big trouble, you are my last hope!

I have bought a Lenovo netbook(IdeaPad U160-M436GGE), the netbook is broke down. I took it to the local service, but they cant fix, [undefined=undefined]since Jan 4[/undefined]! because, they didnt find any BIOS file! (charge Controller and bios chip must be replaced, bios needed to write it...)
I call the local Lenovo service, and they say the same, "sorry we didnt fint any BIOS file to upload your netbook", and they cant call back again...
I call it again (x4) without any result.
Than i call and write to the international support, but they say the same, amazing... I write for 5 different people (on the net) who have the same netbook, for backup the bios, but they dont want to help...
I write for the phonix company, again without any result...

So anyone have an idea, where to got a BIOS file?
