Hopefully someone can help me figure this out.

I have an HP Pavilion Gaming Laptop DK1056WM

Board has been thoroughly cleaned and worked for a while but now this.

when the power button is pressed, the fans spin for a few seconds then stop no boot or anything on screen.
I would like to note I've removed the ram and pressed the power button and it's completely the same with fans spin 2 seconds then nothing.

When power cord is plugged in and no battery installed the light on the jack lights until the battery is plugged in then it goes out....

Short Version.

I need a good bios for a Lenovo L340?
Motherboard Says NM-C091 it's non touch screen.

Not mine. I'm repairing it. No serial number available. It would not boot only power button flashing. No Stickers I'm only going by what the motherboard says. And did some research to get L340
I'm including my bios dump. If someone could help that would be awesome!...
