Toshiba satellite L850 13U Inventec DK10FG MP 6050A2491301 rX01

Hello!
I would need a schematic for the toshiba satellite L850 13U laptop and advices for repair options.
The MB is: E89382 Hannstar J MV-4 94V-0 1215

The problem is the user hijacked the power supply and now the laptop does not turn on. I measured with own PS and it does not have 3V/5V on it...
After the power plug connects to the board the ~19/20V decreases to 0.8/0.9V.
I think the bad part is a FET...
I am not so prof right now, i am learnin into it...
Thank for any help!

I can find for example the power in but the number on board is not found in the pdf...
Any ideas?

Re: Toshiba satellite L850 13U

Is possible.
The motherboards for the major brands are made by a couple of factories. Most common are: Compal, Quantra, Foxconn, Hannstar, Inventec and Wistron.
Often the major brands order a motherboard for 1 type of laptop (In your case Toshiba L850) by different factories. That's why you have the missmatch with the components. Basicly the board functions are the same, but the composition differs because of different factories.
That's why the boardnumber is very important when you ask for schematics.
Mostly there are numbers on both sides and you learn to recognize the factory number and name.
