At begin, laptop has not turn on. I have replace damaged elements, and correct paths, which i saw. After that, i get 3V and 5V.
At now : after plug in DC jack current is growing up to 0,4A without pushing power on button.Graphics chip RC415ME is getting hot little extremely. After 10-15 sec. impossible to touch. I replace him whitch used another chip but nothing has change. Voltages appear at coils: 3V, 5V, 1,2V, and 19V on charger.
After swich on, current is ~1A and grow to 1,3A. Power led lights and it's over.
All measurement are on board with CPU and RAM.

RC415ME греется может по 3 причинам
1- неправильное питание ( проверяйте напряжение и его пульсации),
2- не исправен он сам( то что вы его заменили не исключает это),
3- что то его просаживает по внешним шинам.
-------------------------------------------------------------------------------
RC415ME heated may to 3 reasons
1 - unhealthy diet ( check the voltage and ripple),
2 - defective himself( what you replaced it does not exclude it),
3 - that it reduces external buses.

These not all voltages needed for starting mainboard. You need check all voltages on the coils.

----------------------------------------------------------

3V, 5V, 1,2V, 19V - to nie wszystkie napięcia potrzebne do uruchomienia płyty głównej.
Zmierz napięcia na wszystkich cewkach.

You forgot about another voltages, check the "V" on VGA chip. Also check the power converter witch one give power to the graphic card.

That are all voltages. Im worried about 3V and 5V. They are little too high. When i put 3,3V on that coil from power supply or same 5V, there is shortcut somewhere. Supply takes maximum ampers, i tried 1,5A and still the same. NB is not getting hot. Indeed nothing is hot, or i cant find.
resistance on that coils:
3V going from 1M to 10Kom and stop
5V falls to 30kom from ~2M in 30 sec.

Have you soldered or reballed NB or not? Do you have a POST card?

I have replace NB from other mainboard, X51RL v. 2.0. Both were hot in the same way. I have post card but nothing is changing when computer turns on, circut stop instant on 1,2A. Only growing up when cpu and bridghes coimg hotter.
I have desoldered two points after 3.3V and 5V coils and still the same. Im worried about that, when i put voltage to one of them, power supply takes max amps. Ofcourse good voltage to good coil.
Why resistance on that coils going to ~10-20kom from 2-3Mom? Its normal? Additionally voltages on that coils are little too high.

Может проще новую плату купить?

Może lepiej kupić nową płytę główną?

In fact if i need that computer for customer i had probably bought new board as you suggest. It's hard case, but it's good for training. Ofcourse will be nice to fix that mobo :). I bought at start same board for replacing elements, so it's easier anyway.

I dont have the schematic right here but..... what about memory power supply ? usually works with 1.8 /1.5 and i didn't see these in your checklist.

Don't worry so much about 3V and 5V, these lines are controlled by a IC that have so many "protections systems", if something is wrong the voltage is pulled down.

Electronics is something inpredictible but i bet for a short in secondary lines
