Akoya S6212T Medion MD99270 schematics

Would love schematics for above. Seems to have weird power on circuit.
MoBo labelled as HannStar J E89382

Invalid motherboard model number. If you can't find the correct one, post pictures.

The only labels (other than "Made in China" and component labels) is:-
E89382
HannStar J MV-4
94V-0 1 330

I am assuming the MV-4 must be significant but it was well spaced away from the rest.
My apologies, my first post and request.
Normally work without schematics.
If the MV-4 does not compute, please reply & I will try and post a couple of photos.
The laptop was sold under the Medion brand which is Aldi here in Australia.
The bottom cover carries a sticker Akoya S6212T

No that's just generic markings from PCB manufacturer. Most motherboards will have those markings.

Hidden under the heatsink tube is P/N:15BFT4-0011000 and what appears to be a series of modification state check boxes. Does this help?
Have photos - now how do I attach them?

Thanks - I guess that is why my many hours of searching was without success.
Any idea who made the board? Maybe another schematic from the same manufacturer might give some indication of the power on circuit - it seems that the pwron button applies 3.3 rather than shorting to earth and then I cannot find connection to the startup chip.
Do you feel that flashing the bios would achieve anything?
Thanks. anyhow.
