Dell Latitude E5540 Schematics Request

[Thabto]

Hi everyone,
I am requesting for schematics for a Dell Latitude E5540.
Mainboard: LA-A101P Rev. 1.0 A00

The Issue...
My laptop will not boot successfully / complete boot. When I press the power button the CPU fan spins, and after 2 or 3 seconds the laptop powers off. But during the 3 seconds, you can hear the hard drive spinning also, but I don't get display. After it powers off the wifi and hdd led's are lit solid white, and the battery/charging led will be flashing (white).
I am planning on backing and flashing all three winbond chips U1, U2 and U7. Will that solve my issue?
Let me know. Thanks
