But i need the power supply pinout. Could you help me, with this??? Please!

@Totos82 .... two years late, but here is the power pinouts for the Hyundai Super LT-3 286.,
I did not have a powersupply, so i made one of a normal stock 19v powersupply connected to two buck-converters, one for the 5v and one for the 8v.
Works like a charm.

I took the computer apart, and looked at the connections, you can see the connections at the attached pic.
If for some reason, the image cannot load you can verify it like this using a multimeter, without having to take the computer apart.

- There are four ground connections, all connected to the thield
- There are three +5v connections, all connected.
- There is one +8v connection
